A few cases of patients with both purpuric pigmented dermatitis and cutaneous lymphoma have been reported. The aim of this study was to evaluate the prognosis of purpuric pigmented dermatitis. ⋯ This study shows that purpuric pigmented dermatitis can be associated to or evolve into lymphoproliferative disease. This course should be suspected when purpuric pigmented dermatitis is extensive, long-lasting (> 1 year), has a reticular arrangement and negative patch-testing. In this situation, a long-term follow-up and treatments indicated in the early patch stage of mycosis fungoides (PUVA therapy, chlormethine) seem adequate.

Erosive pustular dermatosis of the scalp is a rare and chronic dermatosis of unknown etiology with non specific histology and without effective treatment. It affects mostly old women. We have observed a 80 year-old male suffering from an erosive pustular dermatosis of the scalp following application of 5 p. 100 fluorouracile cream (Efudex) and his resistance to various treatments including skin graft. ⋯ This recurrence of erosive pustular dermatosis of the scalp following skin graft had never been previously observed before, showing that removing affected skin did not control the disease, suggesting that anti-inflammatory agents probably originating from trauma persist.
