RESUMO
We report a case of subcutaneous fungal abscess over the great toe caused by a keratinophilic fungus, an unknown Chrysosporium sp., in a 60-year-old diabetic female who was treated successfully with oral fluconazole. The fungus was isolated from aspirated pus, and septate hyphae were seen in fine needle aspiration cytology. Ovoid- to club-shaped hyaline one-celled conidia (aleuriconidia) with broad truncated bases were seen, and sequencing of ITS1-5.8S-ITS2 rDNA revealed belonging to the order Onygenales and most closely related to Chrysosporium spp. isolated from a fowl. Of the 65 species within the genus Chrysosporium, very few have been reported as pathogenic.

We report an unusual case of native mitral valve endocarditis in a patient with carcinoma breast in remission. She presented with intermittent fever for 4 weeks. The patient had a chemo port in situ. Blood cultures flagged positive on the 3rd day of incubation. Staining revealed branching acid-fast bacilli, which were subsequently identified as Mycobacterium fortuitum using matrix-assisted laser desorption ionization-time-of-flight mass spectrometry. The patient responded well to medical management alone. Only two such cases have been reported from India previously.

A subcutaneous infection in the form of pseudomycetoma is rare. Acremonium species are rarely considered to be pathogenic in subcutaneous infections due to their ubiquitous nature. We report a case of subcutaneous pseudomycetoma over the dorsolateral aspect of the left knee caused by Acremonium species in a 55-year-old diabetic male who was treated successfully with oral itraconazole.
RESUMO
Rhodococcus equi is an uncommon human pathogen known to cause lung infections in immunocompromised patients. We report two cases of Rhodococcus infections in immunocompetent individuals, who were treated successfully.
