Nocardia abscessus - associated subcutaneous infection in a patient with non-Hodgkin’s lymphoma
This paper describes primary subcutaneous infection caused by Nocardia abscessus in a 60-year-old male patient with the history of non-Hodgkin’s lymphoma and chronic lymphocytic leukemia. The patient was presented with pain and swelling in his left thigh for 45 days. Soft tissue ultrasonography showed a heterogeneous and hypoechoic mass consistent with an abscess. Gram-positive and branched filamentous bacilli, along with neutrophils, were identified in Gram-stained smears of the pus. The pus culture was positive for Gram-positive bacilli, which identified as N. abscessus. Initially, the patient was treated with trimethoprim-sulfamethoxazole (TMP-SMX). Due to insufficient clinical response, ceftriaxone was added for 2 weeks. Then, the patient was prescribed a 3-month course of TMP-SMX. It is important to start appropriate and effective treatment as soon as possible in patients with immunosuppression.
