Disseminated <i>Nocardia paucivorans</i> infection in a 64-year-old patient with first manifestation as an ulnocarpal forearm lesion

We report a 64-year-old immunocompromised patient receiving chemotherapy for metastatic colorectal adenocarcinoma who presented with a purulent forearm lesion. Surgical debridement identified <i>Nocardia paucivorans</i>. PET-CT and MRI revealed pulmonary and cerebral involvement. Escalated antimicrobial therapy achieved complete regression of brain lesions; the patient died 11 months later from underlying disease.
