Eccrine spiradenoma is clinically characterized by a slowly growing, deep-seated nodule occurring most frequently on the ventral surface of the body. It is solitary in 95% of cases. Rarely, multiple lesions may be present and may occur in a linear or zosteriform pattern. Until now only two cases of eccrine spiradenoma in zosteriform pattern have been reported in Korean literatures. A 19-year-old male presented with multiple, gray, macular lesions in a zosteriform distribution along his left subscapular area. These 10-years-old lesions gave him occasional paroxysmal pain. Two years later, the lesions became palpable in the subcutis and were diagnosed as eccrine spiradenoma by an excision biopsy. During the 4 years thereafter, the remaining lesions grew slightly and became symptomatic, which resulted in a second surgical removal. We report a rare case of multiple eccrine spiradenomas with zosteriform distribution with observation of 6 years course.
