Congenital facial teratomas in neonates pose diagnostic challenges, necessitating a multidisciplinary approach for accurate diagnosis and management. We present the case of a four-day-old female infant delivered via Lower Segment Cesarean Section (LSCS) with a protruding nasolabial mass noted since birth. CT brain plain revealed a soft tissue density opacification arising from the left maxilla with an underlying bony outgrowth, suggestive of a benign congenital developmental anomaly most likely teratoma. Further evaluation is warranted to delineate the exact nature and extent of the anomaly. This case underscores the importance of meticulous evaluation and interdisciplinary collaboration in managing congenital anomalies, with surgical intervention potentially required based on individual patient factors. Continued research and collaboration among medical specialities are essential to improve understanding and management strategies for congenital facial teratomas.

Mixed connective tissue disease (MCTD) is characterized by mixed features of systemic lupus erythematosus, systemic sclerosis, and polymyositis/dermatomyositis and is rare in children. Here, we report a case of MCTD in a 10-year-old girl who presented at our hospital with arthralgia, Raynaud's phenomenon, and fatigue. Blood tests were positive for anti-U1-ribonucleoprotein (RNP) antibodies and for rheumatoid factors (RFs) IgG-RF and anti-galactose-deficient IgG. Levels of myogenic enzymes and hypergammaglobulinemia were elevated. Macrophages were prominent in bone marrow, with scattered phagocytic macrophages. MCTD was diagnosed based on the patient's symptoms and laboratory findings. Methylprednisolone pulse therapy combined with oral tacrolimus was administered, which led to resolution of symptoms. Three months after pulse therapy, arthralgia worsened and methotrexate was administered. Arthralgia improved but did not resolve. Magnetic resonance imaging performed to investigate the hip pain revealed a mature ovarian teratoma, which was surgically removed. Because the pain persisted and interfered with her daily life, she was treated with tocilizumab for joint pain relief, which decreased the pain level. Tocilizumab is a candidate for additional treatment of juvenile idiopathic arthritis-like arthritis associated with childhood-onset MCTD.

Review
Pelvic masses frequently originate from the pelvic cavity and are often associated with uterine, ovarian, or intestinal disorders. This report describes the case of a patient with a pelvic mass diagnosed as a retroperitoneal dermoid cyst at our hospital. We analyzed this case and conducted a literature review, to mitigate the risk of misdiagnosis and enhance the treatment of retroperitoneal masses.

Neonates are obligatory nasal breathers hence nasal obstruction is a very important symptom to be evaluated. Although causes can be trivial most of the time, they can be life-threatening in some. Respiratory distress immediately after birth, feeding difficulties, paradoxical cyanosis, and failure to thrive are the most evident symptoms, and determination of unilateral or bilateral involvement guides the rationale for elective or emergency intervention. This study aimed to evaluate the causes, presentation, and management of neonates with nasal obstruction. We collected the data of all the neonates evaluated for nasal obstruction at our hospital over the past 20 years from June 2003 to May 2023 and assessed the strategy of approach for diagnosis and management of those cases. In our study, the commonest cause for neonatal nasal obstruction was found to be choanal atresia and the rarest was iatrogenic. A variety of other causes were also reported. As neonatal nasal obstruction has a multitude of rare causes each carries a unique assessment and treatment plan. History taking and clinical examination are the most important parts of evaluation including endoscopic evaluation in an office-based setup. Imaging studies add to the evaluation of cases of anatomical obstructions and associated anomalies (syndromes). Early diagnosis and swift intervention can be life-saving. The need for follow-up visits and second-stage corrections should be emphasized in getting the best long-term results.

A 51-year-old male presented to our tertiary referral hospital with progressive shortness of breath and orthopnea. A computed tomography (CT) of the chest was performed that showed a large cystic middle mediastinal mass. Magnetic resonance imaging (MRI) of the chest demonstrated a large, well-circumscribed, T2-hyperintense cystic middle mediastinal mass resulting in significant compression of the trachea, brachiocephalic artery, superior vena cava, and azygos vein. The patient subsequently developed a right hemispheric stroke due to compression of the brachiocephalic artery and was too clinically unstable to undergo or definitive operative management of the mediastinal cyst. Percutaneous CT-guided aspiration of the cystic middle mediastinal mass was performed, with successful decompression resulting transient improvement in mass-effect on the surrounding mediastinal structures. Six days after successful aspiration of the mass, the patient underwent attempted bronchoscopy for management of tracheobronchial secretions which was complicated by massive pulmonary hemorrhage leading to cardiopulmonary arrest and death. An autospy was conducted, revealing pathological finding consistent with a mature cystic teratoma.

KEY CLINICAL MESSAGE
When treating a painless or asymptomatic mass in the submental or floor of the mouth, sublingual epidermoid cyst should be considered. Despite its irregularity, preventing malignant transformation is essential for a successful outcome.
ABSTRACT
Dermoid and epidermoid cysts are rarely found in the head and neck region. They account for less than 0.01% of all oral cavity cysts. This is a rare case of a sublingual epidermoid cyst of the oral cavity in a 25-year-old male. The patient presented with a painless sublingual swelling for a duration of 1 month. The clinical examination revealed a non-tender swelling in the sublingual region extending to the submental triangle. Magnetic resonance imaging confirmed a 6.2 × 7.7 × 3.2 cm cystic lesion in the sublingual space. Fine needle aspiration cytology confirmed dermoid cyst contents. Intra-oral surgical excision under general anesthesia was performed successfully. Histopathological analysis revealed that the cyst wall was lined by stratified squamous epithelium. The presence of a prominent granular layer and keratin flakes confirmed the diagnosis of an epidermoid cyst. Postoperative recovery was good, and no recurrence was observed during follow-up. This case emphasizes the infrequent and unusual presentation of a case of a giant plunging sublingual epidermoid cyst and promotes awareness and potential studies in the enhancement of patient care in this area.

OBJECTIVE
Gliomatosis peritonei (GP) is a rare entity characterized by multiple mature glial tissue implants in association with ovarian teratomas in the peritoneum and omentum. To date, only 100 cases have been published. Not much is known about the origin, clinicopathological profile or prognosis of GP. SOX2 and OCT4 are recently recognized markers of embryonic stem cell differentiation. Here, the role of SOX2 and OCT4 in the pathogenesis of 11 cases of GP are reported and clinicopathological factors are described.
MATERIAL AND METHODS
This was a retrospective study of six years duration (2017-2022). All the cases of GP were retrieved from archives, the diagnosis was confirmed and clinicopathological factors were noted. Immunohistochemical (IHC) investigation for glial fibrillary acid protein (GFAP) and S100 was noted wherever available. IHC for SOX2 and OCT4 was performed using an avidin-biotin technique.
RESULTS
There were 11 cases of GP identified. The median age was 29 years and 1/11 cases had nodal gliomatosis as well. There were eight cases of immature teratoma and three cases of mature cystic teratoma. SOX2 was positive in all foci of GP, while OCT4 was negative. These foci were also positive for GFAP and S100.
CONCLUSION
A possibility of GP should be considered as a differential, clinically and radiologically, in cases of omental nodularity. Adequate sampling at the time of surgery is essential to rule out metastasis or growing teratoma syndrome. SOX2, a stem cell marker inducing neural differentiation, may play a crucial role in the development of GP in association with other transcription factors.

OBJECTIVE
The authors analyzed the clinical features and treatment results of surgical patients with a final diagnosis of dermoid cyst on the floor of the mouth over 14 years at our hospital.
PATIENTS AND METHODS
A total of 5 patients with a final diagnosis of dermoid cyst of the floor of the mouth from January 2010 to December 2023 were enrolled.
RESULTS
All patients complained of swelling in the submentum or floor of the mouth. The mean tumor size was 4.2±1.0 cm. All patients underwent complete surgical resection. A transcervical approach was performed in 3 patients, and an intraoral approach was implemented in 2 patients. There were no major complications after surgery with either method. The follow-up period was 71.4±75.7 months. There was no disease recurrence during follow-up.
CONCLUSION
Dermoid cysts rarely occur on the floor of the mouth but should be considered in the differential diagnosis of other oral cavity tumors. Dermoid cysts on the floor of the mouth can be safely removed using the current transoral approach without scarring or recurrence.

PURPOSE
We evaluated the magnetic resonance imaging (MRI) features of ovarian teratomas with somatic-type malignancy (TSMs) and benign ovarian mature cystic teratomas (MCTs) to determine the diagnostic contribution of the MRI findings for differentiating these two teratomas.
METHODS
We compared the MRI findings between ovarian TSMs (n = 10) and MCTs (n = 193), and we conducted a receiver operating characteristic (ROC) analysis to determine the MRI findings' contribution to the differentiation of TSMs from MCTs.
RESULTS
The maximum diameters of whole lesion and the largest solid component in the TSMs were larger than those of the MCTs (p = 0.0001 and p < 0.0001, respectively). Fat tissue in solid components was seen in 73/116 (62.9%) MCTs but in none of the TSMs (p = 0.0001). Ring-like enhancement in solid components was seen in 60/116 (51.7%) MCTs and none of the TSMs (p = 0.0031). On dynamic contrast-enhanced MRI (DCE MRI), all of the solid components in the TSMs showed a high- or intermediate-risk time intensity curve (TIC), and those in 113 of the 116 (97.4%) MCTs showed a low-risk TIC (p < 0.0001). The area under the curve of the ROC analysis using the high-/intermediate-risk TIC on DCE MRI was the highest (0.99) for differentiating TSMs from MCTs: sensitivity 100%, specificity 97.4%, positive predictive value 75.0%, negative predictive value 100%, and accuracy, 97.6%.
CONCLUSION
Compared to ovarian MCTs, ovarian TSMs are larger and have larger solid components with high- or intermediate-risk TICs on DCE MRI. Ovarian MCTs frequently show small solid components with fat tissue, ring-like enhancement, and a low-risk TIC on DCE MRI.

PURPOSE
Pediatric lung tumors are primarily discussed in the surgical literature. However, limited research has been reported on their imaging findings, and only a few tumor types have been documented. Therefore, the aim of this article is to describe the imaging features of primary lung tumors in children.
METHODS
The archives of the pediatric radiology unit were reviewed for primary lung tumors documented between 2007 and 2023. In total, 24 patients (9 girls and 15 boys; aged 5 months to 16 years) were included in the study. Their demographic characteristics, clinical presentation, and histopathologic results were obtained. All imaging studies were reviewed by two radiologists for various findings (e.g., lymphadenopathy, atelectasis, pleural effusion, calcification, multiplicity, pneumothorax, axial and lobar location, laterality, tumor margin, mediastinal shift, contrast enhancement pattern, signal intensity on T1- and T2-weighted images, and diffusion pattern), and a final decision was made by consensus. The mean tumor size was compared between the benign and malignant groups using a t-test.
RESULTS
There were 15 (62.5%) benign tumors, as follows: inflammatory myofibroblastic tumor (IMT; n = 10, 41%), hemangioma (n = 2, 8%), pneumocytoma (n = 2, 8%), and mature cystic teratoma (n = 1, 4%). Moreover, there were 9 (37.5%) malignant tumors, as follows: pleuropulmonary blastoma (PPB; n = 6, 25%), adenocarcinoma (n = 2, 8%), and lymphoepithelioma-like carcinoma (LELC) (n = 1, 4%). The most frequently reported symptoms were cough, fever, dyspnea, chest pain, and recurrent infection; six patients reported no clinical symptoms. Fifteen tumors (62%) were located in the right lung. The mean tumor diameter at the time of diagnosis was 6.4 ± 3 cm (benign group: 6.7 ± 3.4 cm; malignant group: 6 ± 2.3 cm, > 0.050). Calcification was present in 80% of the patients with IMT. At the time of diagnosis, two (8.3%) patients were found to have metastasis: one was diagnosed with adenocarcinoma and the other with LELC. Tumors were located peripherally in 18 (75%) patients.
CONCLUSION
The symptoms associated with lung masses are non-specific. There is no correlation between tumor size and malignancy. The most common tumors observed in this study were IMT and PPB, respectively. IMT is highly associated with calcification.
CLINICAL SIGNIFICANCE
Primary lung tumors are rarely seen in children, and they have different histopathological types. Calcification might be an important radiological clue for the diagnosis of IMT, which is the most common lung tumor in children.
