Pigmented streaks in melanoma scars.
Fifty consecutive patients from our melanoma clinic were examined for the presence of transverse pigmented streaks in their melanoma surgical scars. Thirty-four (68%) patients were noted to have pigmented streaks in their melanoma scars. Ten of these 34 patients also had similar pigmented streaks in their nonmelanoma surgical scars. Long-term follow-up (mean 81.7 +/- 14.5 months, minimum 36 months) of these patients with the melanoma-scar pigmented streaks indicates that the streaks are benign. Histologic examination of a representative pigmented streak revealed basal layer hyperpigmentation without melanocytic hyperplasia. These streaks are frequently associated with the presence of freckles. However, this association may simply be coincidental.
