(1) Background: After thyroid malignancy is ruled out, treatment options for multinodular goiter patients include surgery, levothyroxine suppressive therapy, and 131-I therapy. Surgery effectively reduces goiter size but carries risks of surgical and anesthetic complications. 131-I therapy is the only nonsurgical alternative, but its effectiveness diminishes with goiter size and depends on iodine sufficiency. This study aimed to assess the efficacy and safety of 0.1 mg rhTSH as an adjuvant to a fixed dose of 131-I therapy in patients with a recurrence of large multinodular goiter, several years after the initial thyroidectomy. (2) Methods: 14 patients (13 females and 1 male), aged 59.14 ± 15.44 (range, 35-78 years) received 11mciu of 131-I, 24 h after the administration of 0.1 mg rhTSH. The primary endpoint was the change in thyroid volume (by ultrasound measurements) as well as in the diameter of the predominant nodule during a follow-up period of 10 years. Secondary endpoints were the alterations in thyroid function and potential adverse effects. (3) Results: A significant decrease in the volume of initial thyroid remnants (32.16 ± 16.66 mL) was observed from the first reevaluation (at 4 months, 23.12 ± 11.59 mL) as well as at the end of the follow-up period (10 years, 12.62 ± 8.76 mL), < 0.01. A significant reduction in the dominant nodule was also observed (from 31.71 ± 10.46 mm in the beginning to 26.67 ± 11.05 mm). (4) Conclusions: Further investigation is needed since this approach could be attractive in terms of minimizing the potential risks of reoperation in these patients.

Lipoid lesions of the thyroid gland are very rare. Fat-containing thyroid lesions include a variety of clinical-pathological disorders, such as adenolipomas, thyrolipomatosis, and lipomatous tissue, in the event of amyloidosis. Herein, we report a case of diffuse thyrolipomatosis with amyloidosis and incidentally detected papillary carcinoma of the thyroid in a 51-year-old female patient who clinically presented with a multinodular goiter. Amyloidosis in papillary carcinoma of the thyroid is very rare and can be primary or secondary amyloidosis. Thyrolipomatosis, amyloid goiter, and papillary carcinoma of the thyroid is a rare combination, and to our knowledge, this is the third reported case in the literature. The association of amyloidosis and the rare occurrence of a differentiated carcinoma have to be considered, as in the case of thyroid lipomatosis.

Insufficient thyroid hormone production in newborns is referred to as congenital hypothyroidism. Multinodular goiter (MNG), characterized by an enlarged thyroid gland with multiple nodules, is usually seen in adults and is recognized as a separate disorder from congenital hypothyroidism. Here we performed a linkage analysis of a family with both nongoitrous congenital hypothyroidism and MNG and identified a signal at 15q26.1. Follow-up analyses with whole-genome sequencing and genetic screening in congenital hypothyroidism and MNG cohorts showed that changes in a noncoding TTTG microsatellite on 15q26.1 were frequently observed in congenital hypothyroidism (137 in 989) and MNG (3 in 33) compared with controls (3 in 38,722). Characterization of the noncoding variants with epigenomic data and in vitro experiments suggested that the microsatellite is located in a thyroid-specific transcriptional repressor, and its activity is disrupted by the variants. Collectively, we presented genetic evidence linking nongoitrous congenital hypothyroidism and MNG, providing unique insights into thyroid abnormalities.

Thyroid nodular disease can present in different forms, such as a solitary nodule, multinodular goiter, nodular goiter caused by autoimmune goiter, and nonpalpable thyroid nodules. Among children, thyroid cancer is the most common type of endocrine cancer. Pediatric thyroid cancer is usually detected as a neck mass without any symptoms, leading to variable stages of progression when diagnosed. Papillary thyroid carcinoma is the most common type of thyroid cancer in children with thyroid nodules. We are presenting a case of an 8-year-old male child who was referred to Jimma Medical Center after he developed swelling on the right side of his neck. On examination, multiple, matted 8 × 6 cm, firm to hard, non-tender right lateral neck masses were found, which moved with swallowing. Thyroid function tests were normal. An ultrasound diagnosis of thyroid carcinoma and a cytologic diagnosis of suspicion for papillary thyroid carcinoma (Bethesda V) was made, and an excisional biopsy was advised. A total thyroidectomy was done. A histopathology diagnosis of Papillary thyroid carcinoma (Classic variant) was made. This is an unusual case of Papillary thyroid carcinoma in an Ethiopian child, with plenty of examples previously recorded in the literature but no such report of its occurrence in our setup to our knowledge. When children under 10 have cervical masses, thyroid cancer should be considered. The evaluation of a palpable thyroid mass typically begins with a blood test to check thyroid function, along with ultrasound and fine-needle aspiration biopsy. Currently, fine-needle aspiration biopsy is the most reliable way to diagnose malignancy and determine the appropriate surgical approach. In most cases, treatment will involve a total thyroidectomy. Lymph node dissection is necessary only if lymph node disease is detected during preoperative evaluation.

BACKGROUND
DICER1, a cancer predisposition syndrome (CPS), seems to escape timely diagnosis in pediatric patients. Case report 1: A 16-year-old female patient was referred to the endocrinology ward due to a large goiter. Her medical history indicated normal sexual maturation, with menarche occurring at 13.5 years. Over the past 2.5 years, she had developed pronounced androgenic symptoms, including a deepened male voice; facial, back, and neckline acne; hirsutism; and menstrual irregularities leading to secondary amenorrhea. A thyroid ultrasound identified a multinodular goiter (MNG) with cystic-solid lesions containing calcifications. An abdominal ultrasound identified a 5.7 × 6.9 cm solid mass in the right adnexal region, displacing the uterus to the left. Histopathological examination confirmed a Sertoli-Leydig cell tumor. The patient was subjected to a total thyroidectomy. Histopathology revealed benign follicular cell-derived neoplasms. Thyroid follicular nodular disease (TFND) was diagnosed bilaterally. DNA analysis using NGS, confirmed via the Sanger method, revealed a pathogenic heterozygotic variant c.2953C>T [p.Gln985*] in exon 18 of the gene. Case report 2: A 12-year-old male patient was admitted to the pediatric surgery unit due to a 33 mL goiter. A month prior to his admission, the patient discovered a palpable nodule in his neck, accompanied by hoarseness. An ultrasound revealed MNG. Molecular analysis revealed a pathogenic heterozygotic variant c.2782C>T [p.Gln928*] in exon 17 of the gene. Subsequently, a total thyroidectomy was performed, and histopathological examination revealed TFND bilaterally.
CONCLUSIONS
Recent advances in genetic evaluation and in histological approaches indicate that MNG/TFND, although rare in the pediatric population, when accompanied by characteristic ultrasound and histopathological features, and by additional features such as androgenization, may warrant assessment also of the gene within CPS molecular panel screening.

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.

BACKGROUND
Dermatomyositis is an inflammatory myopathies causing proximal muscle weakness accompanied by muscular inflammation and skin rash. Dermatomyositis patients have a higher incidence of malignancy as compared to the general population.
CASE REPORT
A 52-year-old known female patient with a toxic multi-nodular goiter presented with insidious onset of itchy erythematous rash on her neck and bilateral hands and progressive muscle weakness of 4 months' duration. Associated with this, she had photosensitivity, and periorbital edema of 2 months' duration. On physical examination, she had an anterior neck mass, proximal muscle weakness, periorbital edema, and violaceous skin rash on her bilateral arms, shoulders and neck. Thyroid function tests were normal, creatinine kinase was elevated, and muscle biopsy revealed inflammatory myositis. Ultrasound of the anterior neck mass and analysis of fine needle aspiration suggested thyroid cancer.
CONCLUSION
A high index of clinical suspicion is usually required for early diagnosis of dermatomyositis in resource-limited settings in order to prevent adverse outcomes and identify associated malignancies.

BACKGROUND
Global data reports a low malignancy risk, whereas regional data report a variable risk of malignancy in Bethesda II thyroid nodules. The limited availability of surgical histopathology might have underestimated the risk of malignancy. Here, we report the prevalence of malignancy and its predictors in Bethesda II thyroid nodules for which the surgical histopathological diagnosis was available.
METHODS
This retrospective study was done at a tertiary healthcare center in South India between January 2008 and September 2015. Case records of adults with thyroid nodules who underwent surgery were collected. Patients with inadequate data were excluded from the study. The data was analyzed using SPSS version 21.0 and a p-value of < 0.05 was considered statistically significant.
RESULTS
A total of 563 patients were included in the study with a mean age of 36±12 years. Serum thyrotropin (TSH) was low in 87 (15.4%) patients whereas 362 (64.2%) patients had multinodular goiter (MNG). Sonographic evidence of suspicious cervical lymph node and microcalcification was seen in four (0.7%) and 48 (8.5%) patients, respectively. A total of 48 (8.5%) patients had thyroid carcinoma in the final histopathology. Of these, 42 (87.5%) had papillary thyroid carcinoma, five (10.4%) had follicular thyroid carcinoma and one (4.1%) had anaplastic carcinoma. Age, gender, and maximum nodule size were not associated with malignancy. Thyrotoxicosis was negatively associated with malignancy whereas multi-nodularity, thyroid calcification, or suspicious cervical lymph node on ultrasound and total thyroidectomy were positively associated with malignancy on univariate analysis. On binary logistic regression, only the former four, but not total thyroidectomy, were independent predictors of malignancy.
CONCLUSIONS
We report a high (8.5%) prevalence of malignancy among South Indian patients with Bethesda II thyroid nodules. Thyroid microcalcification, presence of suspicious cervical lymph node on ultrasound, and multinodularity were associated with high and suppressed TSH with low risk of malignancy. Further prospective studies are warranted to confirm the study observations.

: Incidental thyroid cancers (ITCs) are often microcarcinomas. The most frequent histologic type is a papillary microcarcinoma. Papillary thyroid microcarcinomas are defined as papillary thyroid tumours measuring less than 10 mm at their greatest diameter. They are clinically occult and frequently diagnosed incidentally in histopathology reports after a thyroidectomy. The aim of this study is to evaluate the rate of papillary thyroid microcarcinomas (PTMC) in patients who were thyroidectomised with indications of benign disease. : We retrospectively evaluated the histological incidence of PTMC in 431 consecutive patients who, in a 5 year period, underwent a thyroidectomy with benign indications. Patients with benign histology and with known or suspected malignancy were excluded. : Histopathology reports from 540 patients who underwent a total thyroidectomy in our department between 2016 and 2021 were reviewed. A total of 431 patients were thyroidectomised for presumed benign thyroid disease. A total of 395 patients had confirmed benign thyroid disease in the final histopathology, while 36 patients had incidental malignant lesions (33 PTMC-7.67%, one multifocal PTC without microcarcinomas-0.23%, two follicular thyroid carcinoma-0.46%). Out of the PTMC patients, 29 were female and four were male (7.2:1 female-male ratio). The mean age was 54.2 years old. A total of 24 out of 33 patients had multifocal lesions, 11 of which co-existed with macro PTC. Nine patients had unifocal lesions. A total of 21 of these patients were initially operated on for multinodular goitre (64%), while 13 were operated on for Hashimoto/Lymphocytic thyroiditis (36%). : PTMC-often multifocal-is not an uncommon, incidental finding after thyroidectomy for benign thyroid lesions (7.67% in our series) and often co-exists with other incidental malignant lesions (8.35% in our series). The possibility of an underlying papillary microcarcinoma should be taken into account in the management of patients with benign-especially nodular-thyroid disease, and total thyroidectomy should be considered.
