Lobular capillary hemangioma (pyogenic granuloma) with satellitosis.

We describe a 43-year-old white man who rapidly developed multiple, extensive angiomatous lesions on the temple and scalp after excision of a solitary lobular capillary hemangioma. This is a well-recognized but rare event. Our case differs from previously reported examples in terms of the age of the patient, the location and extent of the lesions, the histologic features in the form of small foci of angiosarcoma-like infiltration, and possibly with respect to the response to therapeutic intervention. Because of the alarming clinical picture produced by multiple lobular capillary hemangiomas, in addition to the occurrence of disturbing histologic features, the benign and self-limited nature of this disease must be emphasized.

Disseminated lobular capillary hemangioma (pyogenic granuloma). A clinicopathologic study of two cases.

The eruption of multiple lobular capillary hemangiomas (granulomata pyogenicum) is a previously documented but uncommon phenomenon. Reported cases have featured the recurrence of multiple satellite lesions after surgical removal of, or trauma to, a solitary capillary hemangioma. Sporadic cases of multifocal lesions arising de novo in both previously traumatized and uninjured skin have been described as well. We describe herein two unusual patients with disseminated lobular capillary hemangioma. One patient developed skin nodules in several sites, including the mouth, knee, thumb, and foot, after surgical removal of a solitary oculocutaneous neoplasm. The second patient had more than 700 skin lesions, distributed over the entire body. Unlike those in most previously reported examples of this condition, these two patients were elderly. Both were misdiagnosed clinically as having malignant vascular neoplasms, but the behavior of the lesions was benign, despite conservative surgical excisions in one patient and relative lack of therapeutic intervention in the other.
