Recurrent multiple pyogenic granuloma with multiple satellites. Features of Masson's hemangioma.

The case of a thirteen year old white girl who had multiple recurrences of pyogenic granuloma arranged in a satellite fashion is presented. The incidence and frequency of pyogenic granuloma with or without recurrences is discussed, stressing the unusual nature of the present problem. In addition to the microscopic features of pyogenic granuloma, the changes seen in Masson's hemangioma were demonstrable in some of the sections. The microscopic distinguishing feature of Masson's hemangioma is discussed, with emphasis on the importance of recognizing this as a benign structure rather than a malignant one. Opinions concerning the etiology of pyogenic granuloma as well as the reasons for the development of multiple satellites are presented, along with suggestions for therapy.
