Two cases of multiple eccrine spiradenoma with linear or localized formation.
We report two rare cases of recurrent, multiple eccrine spiradenoma. Both cases presented with extensive lesions comprised of multiple red papules of various sizes and a soft blue-red nodule. The first case was a 30-year-old woman. Her lesions followed a linear arrangement on her chin, and extended down the right side of the neck with spontaneous pain. The second case was a 57-year-old woman with tumors in a localized group on the left occipital region without pain. A search of the literature revealed only 15 reported cases of linear/zosteriform/nevoid multiple eccrine spiradenoma. Both cases were treated by surgical excision. Most of the red papules displayed typical histological features including two cell types: large clear cells with low-density cytoplasm; and small dark cells with high-density cytoplasm. The large soft tumors exhibited a variable histological appearance. In the first case, the cystic tumors displayed an homogeneous structure comprised of eosinophilic material. In the second case, the cystic tumors included abundant interstitial tissue.
