Solitary eccrine syringofibroadenoma

A 78-year-old woman had a 3 years history of a plaque-like lesion measuring 2.5 cm in diameter on her left lumbar region. On histological examination the lesion consisted of anastomosing strands of cuboidal cells with sweat duct lumina within them, embedded in a fibrovascular stroma. A diagnosis of solitary eccrine syringofibroadenoma (ESFA) was made. The authors discuss the nosographical position of this lesion. The single lesion may represent the tumoral form of ESFA on the other hand. multiple and associated lesions may be a sporadic hamartomatous condition.
