Clinical and morphological features of eccrine acrospiroma: analysis of literature data and case from practice.

Eccrine acrospiroma is a rare benign tumor of the skin arising from the epithelial cells of eccrine sweat ducts. The clinical picture is characterized by its variability, so a detailed morphological study of the operative material is necessary to establish a diagnosis. Differential diagnosis must be carried out with hemangioma, melanoma, infected sebaceous cyst, metastatic skin lesion, and other tumors from elements of the sweat gland. In the article the authors presented the clinical and morphological analysis of own case from practice of large eccrine acrospiroma on the back surface of the left thigh which was diagnosed in a 56-year-old man.
