Generalized melanosis complicating disseminated malignant melanoma in pregnancy: a case report.

A case of generalized melanosis complicating disseminated malignant melanoma in pregnancy is described. Four features of this case, unique in combination, are discussed. First, generalized melanosis is a rare complication in macrophages of skin and other areas. Secondly, extensive bone lesions in the absence of roentgenographic changes are an uncommon occurrence. Thirdly, pregnancy probably has little effect on the course of melanoma, as illustrated by this case and a review of the literature. Finally, placental metastases may be more common than generally thought, yet may have little significance to the fetus.
