BACKGROUND: Immature ovarian teratoma is very rare in childhood. We are reporting 12 yo female with immature ovarian teratoma who presented initially with syndrome of inappropriate antidiuretic hormone. CASE: A 12 yo female presented with acute abdomen and distention. Initial laboratory tests showed hyponatremia (sodium -123 mmol/L), that did not respond to fluid management. Computerized tomography showed a 15 cm x 9 cm x 20 cm mass in the right ovary with multifocal internal fat, and dystrophic calcifications...

Primary ovarian carcinoids are relatively uncommon, either pure (monodermal teratomas) or in association with mature cystic teratomas. Here we reported a unique case of carcinoid arising from the teratomatous bronchial mucosa in an ovarian mature cystic teratoma in a 22-year-old woman. This tumor showed compact trabecular and nested growth pattern with salt-and-pepper chromatin pattern. Mitotic figures were identified (6/10 high power fields) and focal necrosis was present. Immunohistochemically the tumor cells were diffusely positive for TTF1 and CD56, focally positive for synaptophysin, and negative for chromogranin A and CDX2...

The occurrence of malignant transformation in mature cystic teratoma of the ovary is rare, with squamous cell carcinoma being the most common histologic type. Sarcomatous transformation has been rarely described in the literature. We present a case of leiomyosarcoma with a minor component of squamous cell carcinoma arising in mature cystic teratoma of ovary in a 65-year-old woman. The malignant tumor showed two distinct components of sarcomatous and invasive epithelial elements, which were confirmed by immunostaining...

Adenomatoid tumors (ATs) are rare, benign neoplasms occurring mainly in reproductive organs such as the uterus, ovaries, fallopian tubes, and testes. Uterine adenomatoid tumors (UATs) are generally incidentally diagnosed during histopathological examination of excisional biopsies performed for other indications, most commonly uterine leiomyomas. We herein present a 38-year-old woman who underwent laparoscopic excision of a uterine leiomyoma and a right ovarian teratoma. Microscopic examination of the excisional biopsy revealed that the enucleated uterine tumor was composed of proliferating glandular tissue covered with single-layered cells that were surrounded by proliferating smooth muscle cells, corresponding exactly to the features of UATs...

Mature teratomas are the most common ovarian neoplasms, accounting for 40% to 50% of ovarian tumors, and are histologically defined by the presence of multiple lineages of mature differentiated cells derived from one or more of the 3 embryonic germ layers; ectoderm, mesoderm, and endoderm. Neuroectodermal and neural crest differentiation can be observed in mature teratomas, but it is uncommon to find secondary tumors that arise from the neural crest lineage. Herein we report the uncommon finding of a ganglioneuroma arising in a mature cystic teratoma in a 26-yr-old woman...

Malignant transformation of the fallopian tube mucosa, followed by exfoliation of malignant cells onto ovarian and/or peritoneal surfaces, has been implicated as the origin of most pelvic high-grade serous carcinoma. Whether a parallel pathway exists for pelvic low-grade serous tumors [ovarian serous borderline tumor (SBT) and low-grade serous carcinoma (LGSC)] remains to be fully elucidated. The literature is challenging to interpret due to variation in the diagnostic criteria and terminology for cytologically low-grade proliferations of the fallopian tube mucosa, as well as variation in fallopian tube specimen sampling...

Primary Squamous Cell Carcinoma (SCC) is a rare tumour which arises in a mature cystic teratoma, endometrioma or Brenner tumour. The pure variety arises from metaplasia of surface epithelium of ovary and it is the rarest type. For optimal management no definitive treatment protocol is available till date. Also, there is no agreement concerning the postoperative therapy-chemotherapy or radiotherapy. We present a rare case of pure primary SCC of ovary which was managed by aggressive cytoreductive surgery followed by chemotherapy...

A 67-year-old uniparous woman had undergone surgery for acute perforated gastric ulcer 10 years prior to the current presentation. Although abdominal computed tomography (CT) performed at that point had revealed a mature cystic teratoma measuring 6 cm in diameter in the right ovary, it was left untreated. She visited the department of surgery at our hospital with chief complaints of appetite loss, nausea, and vomiting that had persisted for the prior two weeks. She was admitted with a diagnosis of ileus attributed to an abdominal incisional hernia...

INTRODUCTION: Mature Cystic Teratoma (MCT) is the most common benign neoplasm of the ovary constituting 10-20% of all the ovarian tumours. Although, much has been published about ovarian teratomas, in English literature, there are very few retrospective cross sectional studies from India to understand the epidemiology of the disease. AIM: To evaluate the prevalence, clinicopathological characteristics and complications of MCT of the ovary. MATERIALS AND METHODS: This was a retrospective study of 223 cases of MCT of ovary received over a period of 25 years from 1990 to 2014...

Autoamputated ovary with mature cystic teratoma (MCT) is a rarely reported gynecologic entity with an unknown prevalence. A 34-year-old woman referred to our clinic for presumed left ovarian tumor. Pelvic examination, ultrasonography and computed tomography scan revealed a 5-cm, cystic ovarian mass with calcification and fat component, and tumor markers were as follows, cancer antigen (CA) 125; 10.4 U/mL, CA19-9; 2 U/mL. Laparoscopy was performed. The mass was identified in the left adnexal region without any ligamentous or direct connection with the pelvic organs...
