title: [Benign course of malignant atrophic papulosis (Köhlmeier-Degos disease): lack of vessel occlusion as good prognostic sign?].
abstract: Morbus Köhlmeier-Degos is a rare systemic disease characterized by pathognomonic cutaneous lesions with typical histology. We report the case of a 22-year-old woman with a benign course of this disease and discuss therapeutical options. The patient presented with whitish papules on neck, trunk and extremities that slowly developed within seven months. Examination of the skin revealed about 20 papules of 2-5 mm size. The lesions were partly skin-colored, partly with an erythematous rim and showed a central porcelain-like atrophy. Histology showed an interface-dermatitis and a wedge-shaped mucin deposition with sclerosis of the upper reticular dermis. Organ manifestation was absent. The patient was started on a daily therapy of 300 mg acetyl salicylic acid. Over the course of 24 months single new lesions appeared at a reduced frequency. Apart from the malignant form of Morbus Köhlmeier-Degos there exists a benign course which may be successfully controlled with anti-platelet therapy. We speculate that the lack of vessel occlusion in the histology could be a hallmark of a benign form of this rare disease.
