Nocardia species are aerobic, Gram-positive actinomycetes often causing opportunistic infections, particularly in immunocompromised hosts. Nocardia farcinica is notable for disseminated nocardiosis (DN), frequently involving the lungs and central nervous system (CNS). Cushing's syndrome (CS), characterized by hypercortisolemia, further predisposes patients to severe infections. We report a 73-year-old woman with ACTH-dependent CS due to a pituitary adenoma who developed DN with pleuropulmonary, CNS, and gluteal abscesses. Diagnosis was confirmed through cultures and MALDI-TOF MS, identifying N. farcinica. Resistance to standard antibiotics required a tailored regimen, including imipenem, amikacin, and moxifloxacin, alongside surgical management of abscesses and the adenoma. This case emphasizes the importance of rapid diagnostic methods and individualized therapies in managing DN with CS, a rare but severe combination. It highlights the need for vigilance in high-risk patients and contributes valuable insights for optimizing outcomes in such complex cases.

Background: species are rare opportunistic pathogens in the clinic, with strong invasiveness and dissemination, that can cause serious pulmonary infection, especially in immunocompromised patients, chronic lung diseases and hormone use, and is easy to be missed and misdiagnosed, preventing patients from obtaining timely and effective treatment, resulting in a high mortality rate.
Case Presentation: Here, we present a rare case of a patient with chronic bronchiectasis and IgA nephropathy who developed pneumonia shortly after hormone therapy. The patient presented with tongue and lip ulcers, chest distress, cough, expectoration, and fever as the initial symptoms, which were extremely similar to common bacterial pulmonary infections.

Nocardiosis caused by is exceptionally rare and characterized by a high mortality rate. It typically affects immunocompromised patients, resulting in severe pulmonary or disseminated infections, and is notorious for abscess formation. Empyema resulting from nocardiosis is even less common.

We report a 73-year-old immunocompromised man with multiple muscle abscesses, in a toxic state with neurological deficits, with a history of panhypopituitarism, diabetes, hypothyroidism, and recent SARS-CoV-2 infection. MRI showed abscesses in the right chest wall, right thigh (peri-implant), and left adductor. Elevated inflammatory markers, comorbidities and clinical presentation suggested disseminated fungal or Nocardial infection.

Introduction: The aim of the study was to study the clinical profile and outcomes of nocardiosis in renal allograft recipients.
Methods: This was a retrospective study of clinical outcomes in consecutive renal allograft recipients with infection over a 22-year period (2000-2022) from a tertiary care center in Southern India. The clinical data were obtained from electronic medical records and patient files.
