Prognosis for polypoidal melanoma is determined by primary tumor thickness.
Survival of 23 patients with polypoidal malignant melanomas was compared with an identical number of patients with nonpolypoidal melanomas of similar thickness, stage, and location. Five-year survivals for the two groups were not significantly different. The dominant prognostic factor leading to the adverse prognosis associated with polypoidal melanomas was the primary tumor thickness (all greater than 1.70 mm) and not the polypoidal morphologic configuration per se.
