Eruptive angiomata in malignant disease.

Summary We report the eruption of multiple angiomata in four patients with the following malignant diseases: Hodgkin's disease, chronic lymphatic leukaemia, probable disseminated melanoma, and multiple myeloma. In three cases the lesions were capillary haemangiomata, closely resembling granuloma pyogenicum, while in the fourth they were cavernous haemangiomata. In three cases no malignant cells were seen in the lesions, while there was a lymphocytic infiltrate in the lesions of the patient with lymphatic leukaemia. A possible explanation is that the malignant cells secreted an angiogenic factor.
