Eccrine Syringofibroadenoma Arising from Nevus Sebaceous / 대한피부과학회지

ABSTRACT

Eccrine syringofibroadenoma (ESFA) is a rare, benign adnexal neoplasm of eccrine differentiation. It is typically located on the limbs and presents as a plaque or a solitary hyperkeratotic nodule in an adult. However, there are several clinical subtypes, ranging from a solitary papule or nodule to multiple lesions with linear or diffuse distribution. Despite the diverse clinical presentation, ESFA is histologically similar. It commonly shows proliferation of anastomosing cords and strands of cuboidal epithelial cells with or without lumina embedded in a fibrovascular stroma. Herein, we report an unusual case of ESFA with verrucous surfaced plaque present on the scalp since birth in a 22-year-old man.
