[Degos' malignant atrophic papulosis. Ultrastructural study of a new case].

The authors report a case of Degos' malignant atrophic papulosis (MAP) with typical skin lesions from a clinical and histological standpoint. They stress in particular the ultrastructural study of skin biopsies which revealed numerous "paramyxovirus-like" tubulo-reticular structures in the endothelial cells, lymphocytes of the perivascular infiltrate, fibroblasts and keratinocytes. Although the significance of these inclusions remains open to discussion and is probably non-specific, their frequency in MAP is worthy of emphasis.
