Summary: BMT (allo-BMT); the third an auto-BMT; all were suffer- ing from acute non-lymphocytic leukemia (ANLL). Three patients with ANLL developed Fournier’s gang- rene as an early complication after allo-BMT (two cases) and auto-BMT (one case); two patients were in Case reports first CR, the third had resistant disease. Patients developed fever, perineal pain, swelling and blistering Case No. 1 of the genital area.

A mortality rate of 30–50% has been reported;2,3,6 predisposing factors include mellitus, perineal trauma or infection, chronic , malignancies and an immunocompro- mised status.3 Despite the severe immunodeficiency that occurs in patients who undergo bone marrow transplan- tation (BMT),7 Fournier’s gangrene has been described in only one case of autologous BMT (auto-BMT).8 We report three further cases who developed FG in the early cytopenic post-transplant phase.

Two days later, the lesions reached the pubis and dusky discoloration of the skin was observed associated with ulceration and pain. Hematological and biochemical characteristics of the patient at this time are shown in Table 1. Pseudomonas aeruginosa was isolated from the lesions and Fournier’s gangrene was diagnosed. WBC count and platelets count were respectively 0.16 × 109/l and 0.09 × 109/l. Systemic therapy with amikacin 500 mg/12 h was started. The fever disappeared 2 days later but the pain and swelling spread to the anterior abdominal wall.
