Mature cystic teratoma is one of the most common ovarian neoplasms, but extragonadal teratoma is rare. Teratoma in Douglas' pouch is extremely rare, and only 12 cases have been reported since the first case was described in 1978. We report a 20-year-old woman with a multicystic mass in Douglas' pouch that was treated via laparoscopic resection. The tumor consisted of cysts lined by stratified s...

A extragonadal malignant teratoma of the extremity is a rare phenomenon. We describe a extremely rare case of malignant teratoma of the left proximal humerus in a 14-yr-old female. Radiologic evaluations, including magnetic resonance imaging, suggested a malignant bone tumor, but a pathological examination revealed an immature bony teratoma. Bone scintigraphy and positron emission tomography co...

A young woman presenting with an ovarian immature teratoma (stage IA, grade 2) demonstrates the dilemma associated with the decision to withhold adjuvant chemotherapy of documented clinical utility in a setting where highly effective treatment is available should the cancer ultimately recur.

Mature teratoma of the pituitary-hypothalamic region is rarely reported in the literature. In this article, we present a 13-year-old girl with clinical and radiological findings that were initially considered as germinoma. However, histological examinations disclosed a mature teratoma. This case highlights that the radiation-induced cerebral edema caused acute hydrocephalus. The mature teratoma...

Most sacrococcygeal teratomas present between the 22nd and the 34th week of gestation. The diagnosis of sacrococcygeal teratoma on routine antenatal sonograms is associated with a greater than expected incidence of prenatal and perinatal complications. We report a premature baby with intrauterine spontaneous rupture of giant sacrococcygeal teratoma which was managed successfully.

Intrathoracic teratoma usually occurs in the mediastinum but rarely, these may originate from the lung. We report a case of an intrapulmonary teratoma in a 34-year-old male.

The appearance of an anterior mediastinal mass during the follow-up of patients successfully treated for lymphoma is worrisome, and may suggest treatment failure. However, benign 'rebound' thymic hyperplasia (TH), a well documented phenomenon in children [1-3] and in young adults treated for malignant testicular teratoma [4], is an important differential diagnosis even in the adult population [5].

Teratoma in the nasopharynx is one of the rare causes for nasal symptoms in the newborn. The present report was on a term "neonate" who had respiratory distress from a hidden teratoma. Cheaper and readily available investigation modalities including postnasal space X-ray and examination under anesthesia revealed nothing. A postnasal space computed tomography also revealed nothing. Magnetic reso...
