Teratoma of mediastinum is rare germ cell tumor. Anterior mediastinum is the most common extragonadal site. Benign mediastinal teratoma accounts for 60% of all mediastinal germ cell tumors. Benign mature teratoma has excellent prognosis after surgical excision. We present a case of 20-year-old woman diagnosed as benign mature teratoma which compressed main pulmonary trunk. The patient underwent surgical excision.

Giant lipomas, rare benign tumours composed of mature adipose tissue, represent only 1% of all lipomas, typically exceeding 10 cm in diameter or weighing over 1000 g. These tumours can cause nerve compression, discomfort, or functional impairment, necessitating surgical excision. We report a 52-year-old male with a giant intramuscular lipoma in the periscapular region, initially identified following significant weight loss after bariatric surgery.

We reported a case of ovarian Fetiform teratoma in a 38 years old nulliparous woman presented with right side abdominal distention of 10 years duration. An ultrasound revealed a heterogeneous pelvic cystic mass that ranged in appearance from fully hyperechoic to fully hypoechoic, suggesting mature cystic teratoma.

Growing teratoma syndrome (GTS) is characterized by a reduction in serum tumor markers despite the growth of a benign mature teratomatous mass following chemotherapy for germ cell tumors. Gliomatosis peritonei (GP) typically accompanies ovarian teratomas, marked by the dissemination of mature glial tissue across the peritoneum. The concurrent presence of GTS and GP after treatment for ovarian immature teratoma (IMT) is notably rare, with approximately 20 reported cases.

Purpose: Ovarian mature cystic teratoma (MCT) is the most common ovarian tumor, and only a small fraction undergoes malignant transformation. The most prevalent malignant type of the ovary is squamous cell carcinoma, followed by adenocarcinoma. However, ruptured ovarian mature cystic teratoma with adenocarcinoma transformation is extremely rare.
