Background Acromegaly is a rare disease that is frequently associated with thyroid diseases. The exact prevalence of goiter and thyroid dysfunction remains uncertain. Objectives This study aims to provide a comprehensive description of the clinical, morphological, and biochemical features of thyroid disorder in Saudi patients with acromegaly and to establish its correlation with the activity and duration of the disease. Methods This retrospective study involved patients who were diagnosed with acromegaly during the period 2006-2023 in an outpatient endocrine clinic at a tertiary hospital. Results A total of 40 patients with acromegaly (27 males and 13 females) were identified and included in the analysis, with a mean age of 46.78 ± 13.76 years and an estimated duration of disease of 8.08 ± 6.43 years. Goiter was diagnosed in 28 patients (70.0%), including multinodular goiter (MNG) (70.0%), solitary thyroid nodules (14.2%), and thyroid cysts (14.2%). Primary hypothyroidism was present at 40.0%. Goiter was not correlated with estimated insulin-like growth factor 1 (IGF-1) levels or disease duration. In 40 patients with nodular goiter, fine needle biopsies were performed in six cases; five nodules were benign, and one nodule was a follicular lesion of unknown significance (Bethesda III). Conclusions The patients with acromegaly have a high prevalence of nodular thyroid disorders and thyroid dysfunction. No cases of thyroid cancer were found in our study. The periodic ultrasonography assessment of the thyroid is needed for evaluating patients with acromegaly.

Multinodular goiter (MNG) is a chronic benign nodular enlargement of the thyroid gland. It presents as an anterior painless neck mass, potentially progressing to exert pressure on the trachea and esophagus and giving rise to compressive symptoms. MNG is a common thyroid gland disorder; however, retropharyngeal goiter is considered rare with few reported cases. We report the cases of two patients who presented to our institution with MNG with retropharyngeal extension: a 62-year-old female patient who presented with a progressive anterior neck mass with dilated neck veins; and a 49-year-old male who presented with a painless anterior neck mass. Both patients successfully underwent total thyroidectomy with an uneventful postoperative recovery. The clinical presentation of MNG with retropharyngeal extension varies with patients; hence, a high index of suspicion is of the utmost significance. While the retropharyngeal extension does not cause compressive symptoms, it should raise the suspicion of a large retrosternal component.

Thyrolipoma is a rare disorder marked by substantial adipose tissue growth inside the thyroid gland. Fatty tissue is frequently seen in salivary glands, thymus, breasts, and pancreas but rarely in the thyroid gland. The fascinating and unusual illness known as thyrolipoma presents challenging diagnostic and therapeutic issues. Due to the rarity of thyrolipoma, doctors must evaluate thyroid nodules with a high index of suspicion, especially those who are radiologically and clinically worrisome. We present a study of a 50-year-old female who came with the complaint of midline neck mass for one year. On clinical examination, a diagnosis of multinodular goiter was made. Computed tomography (CT) scan was suggestive of a heterogenous enhanced thyroid mass lesion. Thus, a total thyroidectomy was performed. On histopathological examination, a final diagnosis of thyrolipoma was made. The abstract aims to provide an overview of the clinical presentation, diagnosis, and treatment options of thyrolipoma, as well as highlight the importance of early recognition and appropriate management of this rare tumor.

parapharyngeal space can have a mass of thyroid origin following metastasis from the thyroid or ectopic thyroid tissue. The extension of multinodular goiter into the parapharyngeal space is rare. A 54-year-old female presented with a 5-month history of neck mass and dyspnea. On examination, a large mass was seen on the right side of the neck which was bulging into the right parapharngeal. In the sonography, a large 50 × 57 mm cyst seen at the upper end of the right lobe of the thyroid. Computed tomography (CT) identified a 46 × 56 mm lesion medial to the right carotid sheath with a mass effect on the parapharyngeal space from the posterolateral aspect and appeared to be an exophytic cystic nodule arising from the upper pole of the right thyroidal lobe. The patient underwent total thyroidectomy, and the final pathology of multinodular goiter was reported. The spread of masses of the thyroid origin to the parapharyngeal space should be considered one of the differential diagnoses of these space masses.

Review
We aimed to analyze the management of the ectopic mediastinal thyroid (EMT) with respect to EMT-related cancer and non-malignant findings related to the pathological report, clinical presentation, imaging traits, endocrine profile, connective tissue to the cervical (eutopic) thyroid gland, biopsy or fine needle aspiration (FNA) results, surgical techniques and post-operatory outcome. This was a comprehensive review based on revising any type of freely PubMed-accessible English, full-length original papers including the keywords "ectopic thyroid" and "mediastinum" from inception until March 2024. We included 89 original articles that specified EMTs data. We classified them into four main groups: (I) studies/case series (n = 10; N = 36 EMT patients); (II) malignant EMTs (N = 22 subjects; except for one newborn with immature teratoma in the EMT, only adults were reported; mean age of 62.94 years; ranges: 34 to 90 years; female to male ratio of 0.9). Histological analysis in adults showed the following: papillary (N = 11/21); follicular variant of the papillary type (N = 2/21); Hürthle cell thyroid follicular malignancy (N = 1/21); poorly differentiated (N = 1/21); anaplastic (N = 2/21); medullary (N = 1/21); lymphoma (N = 2/21); and MALT (mucosa-associated lymphoid tissue) (N = 1/21); (III) benign EMTs with no thyroid anomalies (N = 37 subjects; mean age of 56.32 years; ranges: 30 to 80 years; female to male ratio of 1.8); (IV) benign EMTs with thyroid anomalies (N = 23; female to male ratio of 5.6; average age of 52.1 years). This panel involved clinical/subclinical hypothyroidism (iatrogenic, congenital, thyroiditis-induced, and transitory type upon EMT removal); thyrotoxicosis (including autonomous activity in EMTs that suppressed eutopic gland); autoimmune thyroiditis/Graves's disease; nodules/multinodular goiter and cancer in eutopic thyroid or prior thyroidectomy (before EMT detection). We propose a 10-item algorithm that might help navigate through the EMT domain. To conclude, across this focused-sample analysis (to our knowledge, the largest of its kind) of EMTs, the EMT clinical index of suspicion remains low; a higher rate of cancer is reported than prior data (18.8%), incident imagery-based detection was found in 10-14% of the EMTs; surgery offered an overall good outcome. A wide range of imagery, biopsy/FNA and surgical procedures is part of an otherwise complex personalized management.

BACKGROUND
Despite the presence of evidence that establishes a strong correlation between oxidative stress and thyroid cancer, there exists a scarcity of research that investigates the specific role of glutathione as an important antioxidant in this particular context. The objective of this study was to assess the altered balance of oxidative stress in cases of thyroid cancer, which includes both papillary thyroid carcinoma (PTC) and micro PTC (mPTC), by examining and comparing the total antioxidant capacity (TAC), total oxidant status (TOS), oxidative stress index (OSI), reduced glutathione (GSH), oxidized glutathione (GSSG), and GSSG/GSH ratio with those of individuals diagnosed with multinodular goiter (MNG) as well as Healthy subjects.
MATERIALS AND METHODS
Plasma samples were collected from 92 patients (23 mPTC, 23 PTC, 23 MNG, 23 Healthy). The levels of TAC, TOS, GSH, and GSSG were measured using a commercial assay kits, and the OSI and GSSG/GSH ratio were calculated for each sample. Statistical analyses were performed to compare the oxidative stress between the groups.
RESULTS
The plasma levels of TOS were significantly higher in the mPTC, PTC, and MNG groups compared to the Healthy individuals (p < 0.05). The OSI in the mPTC and PTC groups showed a significant increase compared to the Healthy group (p < 0.05). The levels of GSH in mPTC and PTC were markedly lower compared to the Healthy subjects (p < 0.01). Interestingly, the concentration of GSH in mPTC was found to be considerably lower than in PTC and MNG patients (p < 0.01).
CONCLUSION
These findings indicate that GSH may be a useful biomarker for evaluating oxidative stress and antioxidant system status in patients with PTC, especially mPTC. Low levels of GSH may indicate increased levels of oxidative stress, which may contribute to the development and progression of mPTC to PTC.

Review
Thyroidectomy is common and is performed for malignancy, goiters with pressure symptoms, and certain types of Grave's disease. Weight and body mass index (BMI) following thyroidectomy were discussed controversially. This meta-analysis aimed to assess weight and BMI following thyroidectomy. A systematic literature search was conducted in PubMed, Medline, and Google Scholar with interest in articles that assessed body weight and BMI following total or subtotal thyroidectomy. The search engine was limited to the period from inception up to January 2024. Keywords "total thyroidectomy", "subtotal thyroidectomy", "Graves' disease", "multinodular goiter", "differentiated thyroid carcinoma", and "toxic nodules" were used. Out of the 634 articles retrieved, 89 full texts were screened, and only six studies (five retrospective and one prospective cohort) fulfilled the inclusion and exclusion criteria. No differences were evident regarding weight and BMI before and after thyroidectomy (odds ratio: -0.63, 95%CI: -1.50 to -0.24, P-value for the overall effect: 0.15; and odds ratio: -0.12, 95% CI: -0.41 to -0.16, P-value for the overall effect: 0.40 respectively). No heterogeneity was observed ( for heterogeneity: 0.0%). No association between thyroidectomy (when performed for differentiated thyroid carcinoma and hyperthyroidism), weight, and BMI was found. Further studies assessing thyroid-stimulating hormone (TSH) levels, radioactive iodine therapy, and thyroxine dose are needed.

BACKGROUND
The preferred standard treatment for retrosternal goiter (RSG), a slow-growing, often benign tumor, remains thyroidectomy. An alternative strategy may be required when the goiter is intrathoracic. Data on the results of RSG procedures are rarely reported. Careful patient selection and assessment are critical to avoiding an unexpected sternotomy during surgery and postoperative complications. This study aims to examine the clinical findings and treatment outcomes of RSG and to identify the variables affecting postoperative complications in a resource-limited setting.
METHOD
A retrospective study was conducted at Al-Thawra Modern General Hospital in Sana'a, Yemen, on 69 patients diagnosed with RSG and undergoing thyroidectomy between April 2019 and February 2023. Initial clinical characteristics, radiological and laboratory findings, treatment approach, and outcome were collected from the patient's medical profile and analyzed. To determine the variables influencing postoperative complications, a bivariate analysis was carried out.
RESULTS
The mean age was 51.0 ± 13.6 years, and 45 (65.2%) were female. The most commonly reported symptoms were palpable masses (66; 95.7%), difficulty breathing (45; 65.2%), and neck discomfort (20; 29.0%), with 7 (10.1%) patients being asymptomatic. Previous thyroid surgery was reported in 10 (14.5%) cases. According to the grading classification, grade 1 was the most prevalent (42; 60.9%). Total thyroidectomy was the predominant surgical procedure in 59 (85.5%) cases. Using a cervical approach, all patients underwent thyroidectomy, and a sternotomy was required in one case. Histopathological analysis revealed benign multinodular goiter in 79.7%, followed by papillary thyroid cancer in 10.1% and thyroiditis in 6.7%. The postoperative complication occurred in 22 (31.9%), and the most common complication was transient hypocalcemia (11, 15.9%). There was no mortality during or after the surgery. In bivariate analysis, advanced age, difficulty swallowing, tracheal deviation, large RSG mass, advanced RSG grade, previous surgery, and malignant histopathology were associated with postoperative complications and were statistically significant (all p<0.05).
CONCLUSION
RSG is a rare disease that may require challenging surgical intervention. In this study, the cervical approach was the most practical and least intrusive surgical method. In addition, postoperative complications were associated with advanced age, difficulty swallowing, tracheal deviation, large RSG mass, advanced RSG grade, previous surgery, and malignant histopathology. Low postoperative complication rates can be achieved by understanding the surgical architecture of the neck, essential clinical RSG presentation, thyroid pathology, and necessary surgical treatment.

IMPORTANCE AND IMPORTANCE
Thyroid lipomatosis is a rare entity of thyroid gland lesions. The exact etiopathogenesis of this condition is unknown. Most patients presented with compression symptoms. Radiological investigations such as neck ultrasonography (U/S) and computed tomography (CT) are crucial to evaluate and diagnose fat-containing thyroid tumors, while the definitive diagnosis is achieved by the histopathological study.
CASE PRESENTATION
A 78-year-old female patient, with a background medical history of diabetes mellitus type II and chronic kidney disease, presented to our hospital with a seven-month history of large-sized neck swelling. On physical examination, the neck mass was firm, nodular, hard in consistency, and asymmetrical. The neck swelling was associated with swallowing difficulties and minimal voice changes. Laboratory investigations were unremarkable. Neck U/S showed thyroid goiter. FNA and FNAC were also done. Then, neck CT was performed, and bilateral lobulated fat density was detected. So, a total thyroidectomy was performed, and the resected specimen was sent for histopathology studies. The postoperative period was uneventful.
CLINICAL DISCUSSION
Diffuse thyroid lipomatosis is an unusual non-neoplastic lesion. The clinical features of thyro-lipomatosis include compression symptoms. Radiological tools and cytology aid in diagnosis demonstration but the specific diagnosis is achieved by histopathology.
CONCLUSION
Due to the rare etiologic origin and unknown pathogenesis of thyrolipoma, we report the case of a 78-year-old female patient with enlarged neck swelling, found to be thyroid lipomatosis.

BACKGROUND
Papillary thyroid carcinoma (PTC) is the most frequent thyroid malignancy. Histopathological examination is widely accepted as the gold standard test for the diagnosis of PTC. However, the histopathological examination sometimes can't differentiate PTC from other thyroid diseases. Differentiating PTC from other thyroid diseases is essential for a therapeutic approach and prognosis.
OBJECTIVES
The current study was performed to investigate the utility of TROP-2, SPL-2, and CXCL12 mRNA and protein expression in discriminating PTC from other thyroid diseases that mimic PTC.
METHODS
The current study was performed on 75 cases of surgically resected thyroid glands. The cases were distributed in two groups: the PTC group and the non-PTC group. The PTC group consisted of 35 cases (25 patients of the classic PTC variant and 10 patients of the PTC follicular variant). The non-PTC group consisted of 40 cases (10 cases were multinodular goiter, 5 cases were Graves' disease, 5 cases were Hashimoto thyroiditis, 15 patients were follicular adenoma (FA) and 5 cases were follicular carcinoma). TROP-2, SPL-2, and CXCL12 mRNA expression were estimated by qRT-PCR, and protein expression was estimated by immunohistochemistry.
RESULTS
There were upregulated TROP-2, SPL-2, and CXCL12 mRNA and protein expressions in PTC compared to non-PTC (P< 0.001, for each). There was a statistically significant upregulation in the mRNA expression of the three genes among PTC cases with larger tumor sizes (P< 0.001, for each), those with tumor stages III and IV (P= 0.008, 0.002 and < 0.001 respectively), and those with LN metastasis (P< 0.001, for each). Moreover, there was a statistically significant upregulation in CXCL-12 gene expression among PTC cases with extra-thyroid extension (P< 0.001).
CONCLUSION
mRNA expression of TROP-2, SPL-2, and CXCL12 among PTC cases increased in larger tumor size, tumor stages III and IV, and LN metastasis. Moreover, there was an increase in CXCL-12 gene expression among PTC cases with extra-thyroid extension. Thus, TROP-2, SPL-2, and CXCL12 expressions could be possible diagnostic and prognostic markers in PTC.
