A large abdominal mass was identified during an elective preventative health examination in a 25-yr-old female hybrid orangutan (Pongo pygmaeus). Sonographically, the mass was fluid-filled and a presumptive diagnosis of a dermoid cyst or cystic teratoma of an ovary was made. Exploratory laparotomy,
A 68-year-old woman was diagnosed with mature cystic teratoma of the left ovary when she was 44 years old. The tumor recently enlarged rapidly, and abdominal magnetic resonance imaging revealed an intrapelvic cystic lesion, which measured 123 × 120 × 107 mm and contained a mural nodule. Under a
Pure sebaceous neoplasms arising in dermoid cysts of the ovary are exceedingly rare. A 63-year-old female with abdominal swelling and pain underwent a right salpingo-oophorectomy that showed a unilocular cyst weighing 830 g and measuring 15x12x10 cm, filled with sebaceous material containing a few
Primary glial and neuronal tumors of the ovary or peritoneum are rare neuroectodermal-type tumors similar to their counterparts in the central nervous system. We retrospectively reviewed 11 cases. These cases included 4 ependymomas, 6 astrocytic tumors, and 1 neurocytoma. Patients' age ranged from 9
We report the differential clinicopathologic and immunophenotypical features of 2 pure ovarian ependymomas of extra-axial type with a predominant microcystic, anaplastic pattern occurring in patients aged 22 and 32 years and a unique myxopapillary pigmented ependymoma that originated within an
Adnexal pathology is a rare event in pregnancy, occurring once in 556 deliveries in this study period, during which 23 patients underwent surgery for it. Eleven patients in the first two trimesters received perioperative prophylactic progesterone without a pregnancy loss. Two of three patients
Twenty-four cases of an unusual type of ovarian tumor with functioning stroma in which bands of steroid-hormone-producing cells were located adjacent to the tumor are presented. The cells were of stromal lutein cell type in 14 cases, stromal Leydig cell type in two cases, and hilus cell type in
A prospective collection of serum samples and ovarian cyst fluid was used to assess the use of different tumour markers and cyst fluid cytology in combination with serum tumour markers for the differential diagnosis of benign ovarian cysts. A consecutive series of 108 women of median age 30 years
BACKGROUND
Mature cystic teratomas are the most common form of ovarian tumor in children and adolescents. These tumors are mostly benign and non-secreting. Virilization from an ovarian teratoma is exceptionally rare in pediatrics. Equally rare is the association of ovarian teratomas with auto-immune
BACKGROUND
Increased progesterone levels during pregnancy may cause decidualisation of endometriomas mimicking malignancies on radiology and causing management dilemmas.
METHODS
An ovarian cyst was detected in a 33-year-old woman at her routine 12-week gestation ultrasound scan. By 18 weeks, the
