Pulmonary bacterial pseudomycosis, also referred to as botryomycosis,
is a very rare, indolent illness that has been described mostly in pat
ients with immunological problems. The histological appearance is simi
lar to that of actinomycosis; however, various Gram-positive and Gram-
negative bacteria have been implicated in the pathogenesis. We illustr
ate a rapidly progressive case of pulmonary bacterial pseudomycosis in
a normal host whose presenting complaint was haemoptysis.
