We describe a case of cutaneous Nocardia asteroides infection in a 13-year-old Venezuelan boy with aplastic anemia, following allogeneic BMT. He was receiving immunosuppressive therapy with corticosteroids for GVHD and trimethoprim/sulfamethoxazole (TMP/SMX) for prophylaxis against Pneumocystis carinii pneumonia (PCP). He was not neutropenic and gave no history of cutaneous inoculation or trauma. He developed an abscess on the plantar surface of his right big toe from which Nocardia asteroides was isolated. He was successfully treated with a combination of TMP/SMX and minocycline. Despite prolonged immunosuppressive therapy for GVHD, the infection responded and did not recur. TMP/SMX prophylaxis for PCP in BMT recipients with GVHD does not always prevent nocardial infection but may prevent or delay the development of dissemination.

We describe an unusual case of disseminated subcutaneous abscesses caused by Nocardia asteroides in a 17-year-old female with AML undergoing allogeneic BMT. She was receiving immunosuppressive therapy with CYA and a corticosteroid for acute GVHD, and maintenance therapy with ganciclovir for interstitial pneumonia (IP) caused by CMV, but was not neutropenic. The subcutaneous abscesses spread from the primary infection on her right anterior leg to both thighs, the left buttock, both upper arms, the left forearm and right shoulder, indicating hematogenous dissemination. Nocardia asteroides was identified from biopsy material in culture. The patient was successfully treated with a combination of trimethoprim/sulfamethoxazole (TMP/SMX) and minocycline, given for 3 months. The possibility of nocardiosis should be considered in the differential diagnosis of such patients.

Nocardiosis has rarely been described after BMT. When the doses of immunosuppressive therapy were tapered, a 46-year-old BMT recipient developed chronic graft-versus-host disease (GVHD) and immunosuppresive drugs were increased. Sixteen days later the patient developed nocardiosis diagnosed by lung biopsy. Trimethoprim/sulfamethoxazole (TMP/SMZ) was initiated but the doses were reduced because of rising creatinine levels. Skin and cerebral dissemination of nocardiosis was observed and TMP/SMZ doses were increased. After 4 months, the brain lesion was unaltered despite resolution of pulmonary lesions. Clinical improvement was observed after drainage of the brain abscess.
