Perineural invasion in tumors is typically indicative of malignancy. There are exceptions in most organ systems, but interpretation is complicated when the tumor in question also mimics malignancy. An example of this challenge is found in the interpretation of sclerosing epithelial tumors of the skin. The differential diagnosis for this category of tumors includes malignant entities such as inf...

Microcystic adnexal carcinoma is a rare, locally aggressive neoplasm with both eccrine and follicular differentiation and a high probability of perineural invasion of the centrofacial region. Given the histopathological features of this tumour, early diagnosis is essential for adequate management. This report refers to a case of microcystic adnexal carcinoma of the nasogenial region, with infil...

Heterotopic pregnancy (HP), although common with assisted reproductive techniques, is very rare in spontaneous conceptions. We report the case of a HP in a 41-year-old lady who presented to us with a viable intrauterine pregnancy and an adnexal mass. The ectopic pregnancy was not suspected at her initial presentation. Although cases of HP presenting with ruptured ectopic pregnancy have been rep...

A 79-year-old female was referred to our Gynecologic Department presenting with a pelvic magnetic resonance imaging (MRI), showing an adnexal mass, later confirmed at the pelvic examination. The patient's routine laboratory tests were normal. A sonographic examination was performed with inconclusive results. Although the ultrasonography excluded the presence of vascularization and malignant deg...

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...

Primary fallopian tube carcinoma is a rare malignancy and is not often diagnosed preoperatively. We present a case of a 67-year-old woman who complained of postmenopausal vaginal bleeding. After a negative hysteroscopy, transvaginal ultrasound showed a well vascularized solid-cystic tumor in the adnexal region separate from the ovary. The presence of an adnexal mass was confirmed by MR imaging....

Fallopian tube torsion secondary to an adnexal tumor presents with nonspecific symptoms, and preoperative diagnosis is challenging. We report two cases of hydrosalpinx paraovarian cyst accompanying fallopian that clinically presented recurrent mild lower abdominal pain.

BACKGROUND Differentiation between benign and malignant ovarian neoplasms is essential to create a system for patient referrals. OBJECTIVES The aim of the present prospective trial was to analyze the value of the risk of ovarian malignancy algorithm (ROMA) in prediction of adnexal masses malignancy in pre- and post-menopause women before operation. MATERIALS AND METHODS Preoperative serum s...

AIM To evaluate the performance of subjective evaluation of ultrasound findings (pattern recognition) to discriminate endometriomas from other types of adnexal masses and to compare the demographic and ultrasound characteristics of the true positive cases with those cases that were presumed to be an endometrioma but proved to have a different -histology (false positive cases) and the endometrio...

RATIONALE Adnexal torsion is 1 of the most common emergency gynecological disease. It is more often diagnosed in reproductive age, but rarely in postmenopausal women. The clinical symptoms of adnexal torsion are nonspecific in postmenopausal women. Epithelial ovarian tumors are common in adults, and the risk of malignancy increases with age, especially after menopause. So, it is difficult to di...
