Eccrine spiradenoma (ES) typically presents as a solitary tender lesion. Multiple ES is a rare variant of ES and can present in a segmental, linear, blaschkoid, or zosteriform pattern. The etiology of multiple ES is unknown, but several theories have been suggested including a multipotent stem cell origin. We report the case of a 30-year-old woman with multiple painful ES in a zosteriform pattern on the mid-back and abdomen. Skin biopsy of a representative lesion demonstrated a circumscribed tumor nodule encapsulated by a fibrous capsule with diffuse dense basophilic proliferation located in the dermis. The lesions were then excised on two separate sessions without recurrence.
