Botryomycosis infection closely mimics actinomycosis. About 90 cases of human infection have been recorded, most of which have been cutaneous. However abrominal and thoracic ceases have also been recorded, the latter particularly with long-standing foreign bodies.The condition is characterised by eosinophilic granules surrounded by proteinaceous material? immunoglobulin.
Granulomas and Granulomatous Inflammation

“Palisading” means that the histiocytes are arranged around central necrosis with their nuclei perpendicular to the necrotic center (Fig. 31). Mycobacterial and fungal infection have to be excluded by AFB and GMS stains. In cases with PAS-positive granules, actinomycosis can be present; therefore a Gram stain should be performed, which will show the thin blue filaments of Actinomyces species. Most of these patients will also present with actinomycosis of the paranasal sinuses. If other, usually gram-positive, bacteria are encountered, the diagnosis of a botryomycosis or bacterial pseudomycosis can be made (40).

Botryomycosis is a rare bacterial granulomatous inflammation where the organism forms granules composed of bacterial masses.1 The term botryomycosis is not appropriate as it implies a fungal and not a bacterial infection, it is the term most accepted in the literature.2 It commonly presents in the form of skin or visceral disease, with pulmonary disease being the most common out of the latter. Botryomycosis presenting as an eyelid swelling was unusual and required proper histopathological and microbiological evaluation for diagnosis.
