Superficial Spreading Melanoma Resembling Spitz Nevus on the Plantar Surface

Epidemiology and prognosis of plantar melanoma in 62 Japanese patients over a 28‐year period

“…Sixty‐two patients with plantar melanoma constituted 30% of the 207 patients with malignant melanoma seen at our institute, and the proportions of plantar melanoma to all melanomas in the first and second half periods were 31% (28 out of 90) and 29% (34 out of 117), respectively. Of the 62 patients with plantar melanoma, we diagnosed 51 (82%) as ALM, two as superficial spreading melanoma (SSM), one of whom was reported previously, 13 and nine as nodular melanoma (NM). The proportions of ALM were 96% in the first half period and 70% in the second half period, and ALM was significantly decreased in the second half period ( P = 0.009).…”

Superficial Spreading Melanoma Arising in a Longstanding Melanocytic Nevus on the Sole

“…In the acral regions of Asians, SSM is a rare subtype of melanoma (4,10). To the best of our knowledge, there has been no case report of SSM arising on the sole in Korea.…”
