A 52-year-old man was referred to our department with a 28-year history of painful nodular lesions located on his left buttock and left inguinal region that had recently increased in size and number. The lesions had developed progressively over many years. Cutaneous examination revealed multiple, well-circumscribed, subcutaneous, blue-gray nodules in a zosteriform distribution across the left inguinal region and the left buttock. Some of the painful nodules were large and ulcerated (Figure 1). Computed tomography showed multiple cutaneous nodules but no bone metastases or subcutaneous invasion. Histologic examination of a nodule demonstrated sharply delineated dermal nodules comprising basaloid cells arranged in a trabecular pattern surrounded by eosinophilic fibrous strands (Figure 2). No evidence of malignant transformation was noted. A diagnosis of multiple eccrine spiradenomas was made, and the patient underwent surgical excision of the painful and ulcerated nodules. He was regularly followed up in our department for 12 years.
