Synopsis

Botryomycosis (granular bacteriosis, bacterial pseudomycosis) is an uncommon chronic bacterial infection characterized by fungus-like granules in suppurative foci. Forty percent of cases are due to Staphylococcus aureus, with Pseudomonas spp. causing another 20%, but other agents reported include Proteus, Moraxella, Serratia, E. coli, Corynebacteria, and streptococci. The granules measure 1-3 mm and are yellow-white, resembling actinomycosis.

Disease is reported worldwide; skin involvement accounts for two-thirds of cases. These patients usually have no systemic symptoms, although local pain and pruritus may occur. A visceral form (usually involving the lungs, but sometimes disseminating to kidney, liver, or nodes) may occur in the chronically debilitated.

A history of local injury is common. Patients with low T-cell counts are predisposed, as are patients with alcoholic liver disease, diabetes, HIV, cystic fibrosis, hyper-IgE syndrome, and those on chronic corticosteroids.

Botryomycosis may be confused with cellulitis. Immunosuppression and the finding of lesions discharging a granular, purulent drainage should prompt consideration of this diagnosis.
