Solitary eccrine syringofibroadenoma: typical presentation of a rare neoplasm

Eccrine syringofibroadenoma (ESFA) is a rare, benign adnexal neoplasm originating from the excretory portion of the eccrine sweat glands. Its clinical presentation varies and includes multiple papules, erythematous plaques, or a solitary nodule, the latter being the most common. ESFA is classified into 5 clinical subtypes, all of which share the same histopathological features. To illustrate a typical presentation, we present a case of solitary ESFA successfully treated with surgical excision.
