Eccrine spiradenoma is a benign adnexal neoplasm that has been historically designated as a tumor of eccrine differentiation, although current reconsideration indicates an apocrine process. It usually presents on the trunk and extremities as a tender dermal or subcutaneous papule or nodule frequently with a pink or blue hue. The clinical picture is often not distinct and biopsy is required for diagnosis. Eccrine spiradenoma can present in a variety of ways, including as tumors arranged in zosteriform/dermatomal and/or blaschkoid distributions, often precluding a straightforward diagnosis. Proper diagnosis of eccrine spiradenoma is important due to the occurrence of potentially life-threatening malignant transformation. This article illustrates a rare presentation of eccrine spiradenoma with a concise review for the dermatologist.
