We described a case of cryptococcal mastitis in a 46 years old female patient receiving corticosteroids for sarcoidosis. There was radiological pulmonary deterioration and a cystic lesion was found in the left breast. The mycosis was diagnosed by histopathology and cryptococcal antigens. We emphasized the sarcoid granuloma diagnostic's dilemma an the rare manifestation of cryptococcal infection as mastitis.
The prevalence of specific serotypes of Cryptococcus neoformans in a given area bears on regional epidemiological patterns, the expected spectrum of clinical disease, and predicted response to therapy. In this retrospective study we analyzed the serotypes of 45 degrees C neoformans isolates from 36 North Indian patients with varied clinical presentations. The majority of the isolates were serotype A (87%), and surprisingly, a significant number were serotype B (five isolates, 11%), which caused infection in patients both positive and negative for HIV. One unusual isolate was not typable with factor sera. Study of serotype distribution in patients showed serotypes A and B to be present, respectively, in 92% and 8% of 36 patients. In one apparently immunocompetent patient two serotypes, A and B, were isolated simultaneously from two different sites, lung and scalp abscess. This is the first reported case in which an individual was infected with two serotypes at the same time. In one HIV-infected child serotype A was isolated from blood. Our results suggest that the distribution of serotypes in Indian clinical isolates is different than that found in other regions.
Cryptococcosis primarily occurs in patients with impaired immune response. While pulmonary and/or cerebral involvement are more often described, there is limited experience of its presence in other sites. We present a case of hepatic cryptococcosis with possible pulmonary involvement in a 54-year-old male heart transplant recipient. Two months after heart transplantation, he developed a persistent, moderate dyspnea with fever and signs of liver damage. Diagnosis was made with liver biopsy for a concurrent reactivation of chronic hepatitis B virus (HBV) infection already present before transplant. Along with a mild chronic HBV hepatitis with fibrosis, we observed sinusoidal dilation and groups of bright, rounded, colorless cells with a central nucleus suggestive of cryptococci. Periodic acid-Schiff stain clearly showed encapsulated yeasts, which supported the diagnosis. Cryptococcal antigen was positive in serum and negative in the cerebrospinal fluid. Computed tomography scan of the chest demonstrated a mild interstitial infiltrate. The patient promptly responded to reduction of immunosuppressive therapy and antifungal treatment with amphotericin B lipid complex and flucytosine followed by maintenance treatment with fluconazole. Cryptococcosis should always be considered in the differential diagnosis in immunocompromised hosts with dyspnea and signs of extrapulmonary involvement. Diagnosis of extrapulmonary and extraneural cryptococcosis is difficult and often fortuitous; a histopathological examination of tissues involved is probably warranted.
