Botryomycosis in a lung cavity

Abstract

Botryomycosis is a rare pyogranulomatous disease characterized by suppurative and often granulomatous bacterial infection of the skin, soft tissues and viscera. Only about 90 cases have been reported in world literature till date: 75% of them are cases of cutaneous botryomycosis. Of the 18 reported cases of primary pulmonary botryomycosis, only one had histologically proven botryomycosis in a lung cavity. We report here a case of primary pulmonary botryomycosis occurring in a lung cavity, which is to the best of our knowledge first such case from India. The index case was a 62 year old female who presented to us with recurrent episodes of non-massive streaky hemoptysis with CT chest revealing ′Air Crescent′ sign with a probable fungal ball in a left upper lobe cavity. Left upper pulmonary lobectomy was done and histopathology of the cavitary tissue revealed Splendore-Hoeppli phenomenon and features suggestive of Botryomycosis. Tissue culture from the cavitary specimen grew Pseudomonas aeruginosa. Botryomycosis can mimic Aspergilloma radiologically as was seen in our case, but therapy is often a combination of both medical and surgical measures unlike Aspergilloma.
