Case report 865. Bacillary angiomatosis.

A case of bacillary angiomatosis was presented, characterized by subcutaneous lesions, systemic symptoms, and impressive periostitis which initially masked a small cortical lytic lesion. Review of the reported cases suggests that a diagnosis of bacillary angiomatosis should be strongly considered when periostitis is identified in an AIDS patient with skin lesions. Additionally, deep surgical biopsy of the skin lesion to include the subcutaneous tissue should be performed to confirm the diagnosis if the initial punch biopsies are unrevealing.
