Abstract
A 72-year-old man was referred to us with a black macule of a couple of years' duration on the left sole. It was hyperkeratotic on the surface, accompanied by two black dots in the vicinity. Two hard masses were palpated in the left groin. The macule was resected along with the juxtaposed spots, followed by ipsilateral inguinal lymphadenectomy. Postoperatively, pathology revealed the patient had plantar malignant melanoma with satellite lesions and inguinal metastases (positive in 5/19 nodes resected). The deep margin was not secure near the cutting edge of plantar aponeurosis and we proceeded to resect only the upper layers of the flexor hallucis longus tendon in a peeling fashion with the intention of toe salvage. Notably, two well-demarcated depigmented lesions were observed after adjuvant DAV-feron therapy. As of 20 months after the first surgery there has been no manifestation of local or regional recurrence, which convinces us that the second surgery was valid and sufficed the survival.[Skin Cancer (Japan) 2013 ; 28 : 274-278]
