Malignant atrophic papulosis: response to antiplatelet therapy.
A patient with malignant atrophic papulosis (Degos' disease) is studied. Platelet function studies showed abnormalities of increased adhesiveness and aggregation. Treatment with dipyridamole and aspirin correlated with reversal of these abnormalities and cessation of new lesion development. When treatment was stopped, platelet function abnormalities and new skin lesions developed within 2 months. With reinstitution of therapy, the patient developed no new lesions in the 5 months he was followed. This is the second report of platelet function abnormality and apparent successful treatment with antiplatelet therapy in a patient with Degos' disease.

Acquired perforating dermatosis. Evidence for combined transepidermal elimination of both collagen and elastic fibers.
Patients with renal disease or diabetes mellitus often have an acquired perforating disease of the skin develop that is characterized by hyperkeratotic papules with transepidermal elimination of degenerated material, including collagen or elastic fibers. There is disagreement regarding the most appropriate name for this disease. The pathologic process has been identified by various authors as reactive perforating collagenosis, elastosis perforans serpiginosa, perforating folliculitis, or Kyrle's disease. We have seen four patients with renal disease and/or diabetes whose skin biopsy specimens demonstrated combined transepidermal elimination of both collagen and elastic fibers. This finding is not characteristically seen in any of the previously defined perforating diseases. Since the histologic findings vary greatly in different lesions from different patients with renal disease, we recommend referring to this process as "acquired perforating dermatosis." It is best not to create a new category of perforating disease or to say that a given patient has one of the other four diseases based on random sampling of only a few lesions.

Antiplatelet therapy in atrophie blanche and livedo vasculitis.
Seven patients with atrophie blanche or livedo vasculitis of the lower extremities showed abnormal platelet functions in vitro. Six of seven showed hyperaggregation with epinephrine and/or collagen, three showed increased platelet adhesiveness, three showed increased platelet count, and one showed increased microemboli. After treatment with dipyridamole and aspirin, all showed return to normal platelet function. Clinical improvement occurred in all patients, with significant alleviation of pain and decrease in new lesion formation. Although enhanced healing of lesions seemed evident to physician and patient, it was incomplete. In two patients, pain returned when dipyridamole and aspirin were stopped, but the patients improved again when the medicines were restarted. These preliminary findings indicate a possible beneficial effect of antiplatelet therapy in atrophie blanche and livedo vasculitis. A double-blind study is being undertaken to further study this effect.
