BACKGROUND: Acrospiromas are histologically distinct cutaneous tumours of sweat duct origin and usually measure 1 to 2 cm in size. OBJECTIVE: We describe a patient with a large benign eccrine acrospiroma. METHODS: Case report and literature review. RESULTS: A 50-year-old woman underwent excision of a 5.5×5.0 cm cystic mass located on the left gluteal region, and the resulting defect was closed by a local flap. A diagnosis of benign eccrine acrospiroma was made after histopathological examination. On histological examination, the lesion was characterized by multilobular dermal masses composed of a biphasic cell population. There was no recurrence five months after the operation. CONCLUSION: Although eccrine acrospiromas are usually benign, they can, on rare occasions, undergo malignant transformation. In addition, the clinical appearance of this lesion is not specific and differential diagnosis from other lesions, both benign and malignant, can only be done after the complete removal of the lesion.
