Syringomas are benign adnexal tumors of eccrine origin. Eruptive syringomas clinically present as multiple, skin colored tiny papules that usually develop during a short period of time and are frequently misdiagnosed with other entities. Histopathological examination is essential in the diagnosis and usually reveals numerous, small ducts in the dermis lined with a double row of epithelial cells...

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...

A syringomatous adenoma of the nipple is a benign locally infiltrating neoplasm histologically similar to the syringoma of the skin. Morphologically similar lesions have been described as adenoma of the nipple or florid papillomatosis. Patient was a 33 year old woman who was admitted with a history of bloody nipple discharge from her right breast. With a clinical impression of Paget's disease e...

An 18-year old Afro-Caribbean woman presented with a 2-year history of a gradual onset, severely pruritic eruption affecting her upper chest and arms. The eruption started as crops of itchy papules on her upper chest, which were slowly spreading to her abdomen and inner aspect of both forearms. Emollients and topical steroids had been ineffective. She had no past medical history or family histo...

in this study, we demonstrate the appearance of anatomic defects of the uterine cavity on hsg after cesarian section. we define different shapes such as thin linear defect, focal saccular outpouching, unilateral or bilateral diverticula (dog-ear like) and fistula and different locations such as the uterine body, lower uterine segment, uterine isthmus and the upper endocervical canal. cesarean s...

We report unilateral megalencephaly in a 14-year-old girl with linear sebaceous nevus syndrome. A review of the radiologic findings in this case and in previously reported cases suggests that the seizures and developmental delay in this neurocutaneous syndrome are related to the migration anomaly of unilateral megalencephaly.

Collision or contiguous tumors, defined as two or more distinct tumors occurring at one site, are often an unexpected finding and may represent a diagnostic challenge, as clinical and histological presentations do not always coincide. Various combinations of collision tumors have been described with respect to melanocytic lesions, with the most frequently reported being the combination of nevus...
