Giant pyogenic granuloma of the thigh: a case report

INTRODUCTION Pyogenic granuloma or lobular capillary hemangioma remains an etiopathological enigma, with trauma, inflammatory and infectious agents being the commonest suspected causative agents. These lesions affect mucous membranes of the upper aero-digestive tract, and skin. HIV patients diagnosed with pyogenic granuloma present with multiple lesions, caused by Bartonella spp. CASE PRESENTATION A 28-year-old woman presented with a solitary large tumor on a skin graft donor site on her left thigh. On excision and histological examination the tumor was found to be a lobular capillary hemangioma (pyogenic granuloma). Further investigation in search of a possible explanation for this unusual presentation revealed HIV infection as the underlying cause. CONCLUSION This report underscores the fact that the full spectrum of presentation of HIV infection is still unknown. Unusual or unexpected presentations should arouse suspicion of underlying immunosuppression, especially in HIV endemic areas.
