A rare case of eccrine spiradenoma—treatment and management

A young male patient presented with multiple swellings on his chest and the nape of his neck. Physical examination revealed multiple small papulonodular swellings measuring 0.5 × 0.5 cm to 2 × 2 cm, that were soft without discharge with no surrounding skin changes or induration. Skin biopsy samples were diagnosed as benign adnexal neoplasm consistent with eccrine spiradenoma, trichoepithelioma, and cylindroma, i.e., Brooke–Spiegler syndrome. Having confirmed this to be a case of eccrine spiradenoma, surgical excision was performed and the raw area was covered with a split thickness skin graft taken from the right thigh and sutured over the raw area. The sternal lesion was circumferentially excised and the wound was primarily closed by Z-plasty. Surgical excision is considered the gold standard for the treatment of these cases, with low rates of recurrence. Around 50 such cases have been reported in the literature to date. Although eccrine spiradenomas are usually solitary and small, the findings in our case underscore the fact that a variety of presentations are possible. With strict clinical suspicion and histological criteria, the correct diagnosis can be achieved, especially when combined with pertinent clinical information and laboratory studies. Level of Evidence: Level V, therapeutic study.
