Fig 1. Desmoplastic trichoepithelioma and melanocytic nevus (collision tumor). Dermoscopy of the skin-colored papule on the right cheek (clinical detail) disclosed sharply focused, fine arborizing vessels (arrows), mostly at the periphery on a white-ivory background (black asterisk) in the upper half of the lesion and structureless light-brown (white asterisk) in the lower half. Few white clods...

Brooke-Spiegler syndrome is a rare autosomal recessive disease characterized by adnexal neoplasms, particularly trichoepithelioma, cylindroma, and occasionally spiradenoma, which usually develop in second to third decades of life. We report this syndrome in a 16-year-old woman with tumors on face and scalp.

introduction : brooke-spiegler syndrome (bss) is a rare autosomal dominant disease characterized by the development of multiple adnexal cutaneous tumors such as cylindromas, trichoepitheliomas and spiradenomas. case description: a 49 years old female patient presented with a history of gradual appearance of multiple nodules situated predominantly on the scalp and face. pathologic examination of...

BACKGROUND Infundibulocystic basal cell carcinoma is a recently described distinctive clinicopathologic variant of basal cell carcinoma. Histopathologic differential diagnosis among infundibulocystic basal cell carcinoma, trichoepithelioma, and basaloid follicular hamartoma has generated controversy in the literature. OBSERVATIONS Members of 2 families with multiple infundibulocystic basal ce...

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 origin...

We here describe a case of solitary basaloid follicular hamartoma (BFH) : the case developing in company with senile lentigo on the nose. BFH is a relatively rare benign follicular neoplasm of undetermined etiology. Histologically, the specimen consisted of small-sized squamoid or basaloid cells and follicular germ-like cells in the periphery of the tumor nests. There were no infundibular cysts...
