A clinical follow-up study of 49 cases of spindle and epithelioid cell nevus is presented to address the question about the potential for local recurrence. Only 19 (39%) of the 49 lesions were initially excised en toto, and the remainder (30 cases) had positive margins; six of the latter spindle and epithelioid cell nevi were reexcised, and no evidence of a residual nevus was found in five of the six cases. There were no recurrences in the 49 patients during an average follow-up period of 5.0 years (range, 1 to 10 years). The rarity of recurrent spindle and epithelioid cell nevus would justify a conservative approach to management, with clinical follow-up alone recommended after a subtotal excision, when the pathologic diagnosis is unequivocal.
