Prognostic Variables and Surgical Management of Foot Melanoma : Review of a 25-Year Institutional Experience

Abstract EN

Introduction.

Cutaneous foot melanoma is rare, challenging to manage, and not adequately examined in the literature.

This study evaluated the prognostic variables and surgical management of foot melanoma.

Materials and Methods.

Foot melanoma cases managed at an academic center from 1985 to 2010 were retrospectively reviewed.

Results.

46 patients were identified with a broad range of demographic characteristics.

Overall recurrence was 32.6%: 19% acral lentiginous, 57% nodular, 66% superficial spreading, 30% melanoma unspecified, 50% severely atypical; 53% ulcerated, 23% nonulcerated; 29% on the dorsum of the foot, 17% heel, 60% ankle, 22% toe, 50% plantar; 0% <1 mm thick, 47% 1–4 mm, 33% >4 mm.

13 had positive nodes, 4 (31%) of whom recurred.

Prognostic factors and recurrence did not correlate, and survival was 96% with a median followup of 91 months.

Conclusions.

Aggressive management of foot melanoma may result in excellent long-term survival even following disease recurrence.
