Vitiligo-like primary melanoma.
Depigmented or hypopigmented macules and patches have been described in association to primary and metastatic melanoma. Primary melanoma presenting at the onset as a vitiliginous patch without histopathological evidence of regression seems to be a rare event. We report 2 patients with melanoma in situ that expressed clinically as vitiligo-like patches and review the possible immunologic mechanisms responsible for this unusual presentation.
