“…Spiradenocylindroma is an adnexal neoplasm that shows histopathological characteristics of both spiradenoma and cylindroma. 1 Cylindromas and the hybrid tumor ‘spiradenocylindromas’ are most commonly located on the face and scalp. 1 Dermoscopy may provide significant clues for the diagnosis of adnexal tumors.…”

“…Spiradenocylindromas are benign cutaneous adnexal neoplasms that are derived from apocrine or eccrine glands, demonstrating histopathological features of both spiradenoma and cylindroma. 1 Since a variety of benign and malignant skin disorders such as basal cell carcinoma, dermatofibrosarcoma protuberans, trichoepithelioma, and microcystic adnexal carcinoma may be considered in the differential diagnoses, histopathological examination remains the gold standard. Spiradenocylindromas are characterized by basaloid cells with eosinophilic basement membrane and tubular structures forming a multinodular pattern as the spiradenomatous part; whereas the cylindromatous portion is mainly composed of small nests of triangular or polyhedral tumoral cells forming a complex pattern resembling a jigsaw puzzle.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
