Development of multiple tumors in a sebaceous nevus of Jadassohn.

We report the case of a 56-year-old male with a sebaceous nevus of the scalp, complicated by multiple tumor development. Histologic examination revealed a basal cell carcinoma, a syringocystadenoma papilliferum and a proliferating trichilemmal cyst. Sebaceous nevus has a well-documented neoplastic potential. Multiple tumors may occasionally arise, but the coexistence of 3 or more tumors is extremely rare. Close monitoring and early complete surgical excision of sebaceous nevi are warranted, in order to ensure a favorable prognosis.

Mycosis fungoides: evaluation of immunohistochemical criteria for the early diagnosis of the disease and differentiation between stages.

Lesional skin specimens from twenty-eight patients with mycosis fungoides were studied by evaluating immunohistochemical criteria, primarily with monoclonal antibodies. It was demonstrated that significant differences exist between the control and the premycotic-stage group in regard to the monoclonal antibodies BE1, BE2, and OKT9. The detection of specific antigenic determinants on the surface of cell populations early in the course of the disease seems to be of considerable value for the early diagnosis of the disease. Statistically significant differences were found between the premycotic stage and the plaque stage in regard to T lymphocytes, macrophages, OKT6+, OKT4+, OKT8+, and BE2+ cells in the dermal infiltrate. Significant differences were also shown between the plaque and tumorous groups, concerning macrophages, T cells, and OKT9+ cells in the dermis, as well as epidermal dendritic cells. Differences between stages may supplement histologic data for the follow-up of the disease with or without treatment.
