Generalized melanosis associated with malignant melanoma: unusual histologic appearance.
A case of generalized melanosis associated with malignant melanoma, characterized by up-to-date, previously undescribed histologic findings, is reported. Markedly dilated dermal lymphatics with features resembling secondary lymphangioma were found. We speculate that a further mechanism, as well as those previously reported in the literature, could be operative in the pathogenesis of this disorder of altered pigmentation.
