[Lymphatoid papulosis. Ultrastructural study. Review of the literature].

The authors report a case of lymphomatoid papulosis with an ultrastructural study, and review 84 cases which they found in the literature. They recall the clinical and histological signs and the course of this disease which usually has a benign prognosis. The classification and relationship with varioliform parapsoriasis of Mucha-Habermann and the hematodermias remain debated.
