An otherwise healthy 43-year-old man presented with seven papules that had all erupted within the previous 6 months from an epidermal nevus on his left lower extremity. He reported that one of the new growths was painful and bled with minor trauma. Physical examination revealed a linear blaschkoid cobblestoned dark brown plaque that extended from the disto-lateral left thigh 30 cm to the mid-calf. Within the plaque inferior to the lateral popliteal fossa were six verrucous papules and a 4-mm round, pink, crusted, exophytic papule (Figure 1). A punch biopsy was taken from the plaque and saucerization shave biopsies of all the discrete papules.

Background: Although rare, melanoma confined to the dermis or subcutaneous tissue without evidence of a primary cutaneous site should provoke consideration of melanoma of unknown primary. This diagnosis carries a favorable prognosis when compared with cutaneous metastatic melanoma. Several hypotheses have been proposed for how melanoma of unknown primary develops, two of which were considered in our patient case: (1) spontaneous regression of the primary tumor following metastasis or (2) the traumatic implantation of ectopic melanocytic cells in other tissues, such as the subcutaneous tissue.

There are only a few reported cases of intracranial tumors associated with Schimmelpenning syndrome. In most cases, a single nucleotide mutation in the RAS family proto-oncogenes, like or genes, can result in the genetic mosaicism that is responsible for the clinical manifestations of this syndrome.
