c Abstract: Proliferating Trichilemmal Tumour (PTT) is a rapidly growing large cutaneous adnexal neoplasm. Although biologically considered as benign, it may be locally aggressive. Malignant transformation of these lesions, known as Malignant Proliferating Trichilemmal Tumour (MPTT) has rarely been reported. So far in the literature, only 39 well-documented cases of MPTT have been reported. MPT...

BACKGROUND Psammocarcinoma of the ovary is an uncommon neoplasm, currently classified among the low-grade epithelial serous tumors. Little is known about its pathogenesis and biological behavior. CASE A 35-year-old woman underwent laparotomic myomectomy and surgical removal of the right gonad after the incidental discovery of an adnexal mass. The pathological findings were consistent with ser...

BACKGROUND Differential diagnosis for a nodule in the nipple or subareolar area of woman includes both primary neoplasms of breast as well as those from skin and adnexae. CASE PRESENTATION A 32-year-old woman presented with a painless 0.5 cm subareolar nodule of her left nipple that she had noticed for several months, with no associated nipple discharge. A biopsy revealed an infiltrating adne...

OBJECTIVES To assess the accuracy of the IOTA logistic regression model LR2 for the diagnosis of ovarian cancer. METHODS This was a prospective single-center study of women with an ultrasound diagnosis of an adnexal tumor. They were all examined by a single Level-II ultrasound operator, who had received training in the systematic examination of ovarian tumors in accordance with the IOTA guide...

BACKGROUND Benign metastasizing leiomyoma (BML) is a rare condition described as multiple well-differentiated leiomyomas at sites distant from the uterus. Apart from lungs it has also been reported in lymph nodes, heart, brain, bone, skin, eye and spinal cord. We present a case of pulmonary benign metastasizing leiomyoma in a female patient admitted to our hospital with suspicion of left adnexa...

Dear Editor, Apocrine hidradenoma is a rare benign adnexal tumor related to the more common poroma, as they both originate from sweat glands. Hidradenoma usually has an eccrine differentiation, but an apocrine differentiation is possible. Due to its rarity and non-specific clinical appearance it is difficult to differentiate it from other malignant cutaneous lesions. In this challenging task, d...

Female Wolffian adnexal tumor (WAT) is a rare neoplasm arising from the remnants of the mesonephric duct and <100 cases have been reported globally. The present case report describes a 73-year-old female patient with WAT in the left ovary which, to the best of our knowledge, is the largest benign WAT tumor to be reported. In addition, the present case report reviewed previous studies on the cli...

Female adnexal tumor of probable Wolffian origin (FATWO) is a rare neoplasm arising from the remnants of the mesonephric duct. We report here a case of FATWO in a 70-year-old woman arising from the broad ligament and confirmed on immunohistochemistry. Most of these tumors behave in a benign fashion but certain histological features like hypercellularity, cellular pleomorphism and nuclear atypia...
