ABSTRACT
OBJECTIVE:
We present a case of primary cutaneous mucormycosis in a patient with bone marrow failure secondary to paroxysmal nocturnal haemoglobinuria (PNH). CLINICAL CASE A 60-year-old male patient with a history of PNH, complicated to a severe aplastic anaemia, presented to the emergency department complaining of papules on the lower limbs that rapidly turned into necrotic plaques within 2 months. Histopathological examination showed granulomatous and suppurative dermatitis with tissue necrosis and the presence of non-septate hyphae. Molecular identification was achieved by amplification and sequencing of the 18S-ITS1-5.8S-ITS2-28S rRNA region using the polymerase chain reaction. The sequence showed 100% identity with Rhizopus arrhizus. The patient received treatment with liposomal amphotericin B and surgical debridement. Nonetheless, the patient suffered from severe low red blood cells and platelets and also underwent septic shock; he died 6 days after admission to the hospital.CONCLUSION:
Mucormycosis in the setting of immunosuppression is challenging. Upon suspicion of a diagnosis, immediate treatment is required. Adjunctive therapies may be considered; however, the case fatality rate remains high.Palavras-chave
