A case of nevus verrucosus

A wart-like nevus in a 49-year-old man, resident of Kaluga Province, is described. The diagnosis has been histologically confirmed.     

A case of combined nevus: compound nevus and spindle cell Spitz nevus

Combined nevi consisting of a Spitz nevus and an acquired nevus are unusual, and, to our knowledge, the combination of a spindle cell Spitz nevus and an overlying compound nevus has not been previously reported. We report a 17-year-old girl with a nodule on the left anterior lower extremity. The nodule was asymptomatic, firm, brown, symmetrical, dome-shaped, 8 mm in diameter, and not found with ulceration. Histological findings showed proliferation of spindle-shaped cells with an overlying compound nevus. The spindle-shaped cells were large, non-pigmented, uniform in size and shape, with rare mitoses and without nuclear atypia, and arranged in a storiform pattern in thick collagen bundles. They stained positively for S-100 and negatively for HMB-45. The lesion was considered to be a new type of combined nevus consisting of a spindle cell Spitz nevus and an overlying compound nevus.

A combined case of desmoplastic trichoepithelioma and nevus cell nevus

A 41-year-old woman with desmoplastic trichoepithelioma associated with pigmented nevus presented. Pigmented nevus had been present on her face at birth. She had received cryotherapy and dermabrasion at a small part of the pigmented nevus. As a result of the therapy, the discoloration disappeared. The lesion lately increased and became hard. Histologically, the lesion was composed of two distinctive but intimately mixed cellular components; nevus cells and basaloid cells. In the pigmented lesion, basaloid cells were not present. To our knowledge, this is the first reported case of desmoplastic trichoepithelioma associated with nevocellular nevus in Japan.
