Mature cystic teratomas or dermoid cysts are among the most common ovarian tumors; however, teratomas of extragonadal origin are extremely rare. The most common extragonadal site of these teratomas is the omentum. It is generally accepted that teratomas arise from germ cells that originate in the mature gonads. Of the three proposed causes of omental teratoma, auto-amputation and subsequent re-implantation of gonadal teratoma is the most likely preceding event. A review of the published reports reveals that only 31 cases of teratoma of the greater omentum have been published to date and three cases reported wherein omental teratoma and dermoid of the ovary were coexisting. We report a rare case of an omental teratoma in a 26-year-old woman who underwent ovarian cystectomy for dermoid cyst. This is the fourth case of an omental mature teratoma with coexisting ovarian dermoid cyst.

The aim of this retrospective multicentric case series is to describe the CT findings of ovarian neoplasia in dogs. Twenty dogs with pre- and postcontrast CT exams and cytological/histological diagnosis of ovarian neoplasia were included. Five dogs presented with bilateral tumors, for a total of 25 neoplasms: 15 carcinomas (4 bilateral), 4 granulosa cell tumors, 2 poorly differentiated malignant neoplasia (bilateral), 2 luteomas, 1 teratoma, 1 dysgerminoma.

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.

Mature cystic teratomas (MCTs) arise from totipotent cells. While the ovaries are the most common sites, extragonadal teratomas are very rare.

Article Synopsis
- Malignant struma ovarii (MSO) is an uncommon ovarian tumor mainly made up of thyroid tissue, often spreading to areas like the peritoneum, bones, and lungs.
- A case study involves a woman in her 50s who had a history of ovary removal and presented with a pituitary mass, which was mistakenly thought to be a pituitary tumor but turned out to be metastatic thyroid tissue from MSO.
- After surgery and treatment with radioactive iodine, the patient showed a positive response, with no signs of tumor recurrence or new metastases after five years of monitoring.

BACKGROUND Malignant peritoneal mesothelioma is a rare disease with a poor prognosis that often presents with vague symptoms and inconclusive laboratory test results. Causes include industrial pollutants, primarily asbestos, and certain genetic mutations, such as BAP1. Due to the nonspecific symptoms, it is often incidentally diagnosed during or after other surgical procedures.
