Hidradenocarcinoma (HAC) is an exceedingly rare and aggressive malignant tumor of the adnexal eccrine apocrine sweat gland. Due to its low incidence rate, nonspecific clinical presentation, similar histopathological features benign hidradenoma (HA), HAC often misdiagnosed as counterpart.

A case of an interesting previously unreported mixed adnexal tumor of the scalp of a 38 year old man is presented, which was composed of randomly dispersed areas of trichofolliculoma, trichoepithelioma, and pilomatricoma concomitantly. While these lesions are classified under adnexal tumors with differentiation towards hair follicle structures, controversy is present concerning the exact o...

Wolffian tumor is a rare neoplasm, arising from the remnants of the mesonephric duct, such as the broad ligament, tube, ovarian hilum, peritoneum and mesosalpinx. It is synonyms include Female adnexal tumor of probable wolffian origin (FATWO), wolffian adenoma and wolffian adnexal tumor. It is thought to be a benign lesion, although in some cases metastasis or recurrences have been reported eve...

Extramammary Paget's disease (EMPD) is a distinct form of malignant skin neoplasm. The clinicopathological significance of cutaneous adnexal involvement in EMPD has not been investigated in detail. Surgical specimens were obtained from 53 patients with primary EMPD. Tumor involvement of cutaneous adnexal structures was evaluated using histological parameters. The degree of involvement was score...

OBJECTIVES We compared the indication of laparoscopy for treatment of adnexal masses based on the risk scores and tumor diameters with the indication based on gynecology-oncologists' experience. METHODS This was a prospective study of 174 women who underwent surgery for adnexal tumors (116 laparotomies, 58 laparoscopies). The surgeries begun and completed by laparoscopy, with benign pathologi...

BACKGROUND Lung cancer with ovarian metastasis or adnexal metastasis harboring anaplastic lymphoma kinase (ALK) gene translocation is rare. Crizotinib, a novel ALK tyrosine kinase inhibitor, has already shown an impressive single-agent activity in ALK positive lung cancer. METHODS To summarize the case of clinical data and treatment of a 33-year-old woman with pelvic adnexal metastasis NSCLC....

OBJECTIVE To evaluate the CT features of pathologically proven low grade serous carcinoma (LGSC) of the ovary. METHODS Patients with a pathologic diagnosis of LGSC and CT prior to oophorectomy were retrospectively identified. The CT scans in 14 patients were available and were analyzed for an adnexal mass, peritoneal mass and ascites. The adnexal mass was characterized as complex primarily cy...

Background/Aim. Ovarian cancer is the leading cause of death from gynecologic malignancies. Risk of malignancy index (RMI) is recommended in assessment of patients with adnexal masses. The aim of this study was to verify the effectiveness of the RMI in the discrimination between benign lesions and malignant adnexal masses in clinical practice. Methods. Ultrasounds were performed for all the pat...
