A disseminated cryptococcal infection was diagnosed in an HIV-positive man presenting with fever and lymphadenopathy. Bone marrow examination proved crucial for identifying this opportunistic fungal infection.

Area of Science:

  • Infectious Diseases
  • Hematology
  • Immunology

Background:

  • Opportunistic infections are common in individuals with immunosuppression, particularly Acquired Immunodeficiency Syndrome (AIDS).
  • Disseminated fungal infections, such as cryptococcosis, can present with non-specific symptoms like fever and lymphadenopathy.
  • Bone marrow examination is a valuable diagnostic tool for identifying opportunistic infections in immunocompromised patients.

Observation:

  • A 35-year-old male presented with fever, cervical, and axillary lymphadenopathy, along with thrombocytopaenia.
  • Peripheral blood film revealed thrombocytopaenia.
  • Bone marrow aspiration and biopsy showed granulomas and cryptococcal yeast forms.

Findings:

  • Fine needle aspiration of lymph nodes, cerebrospinal fluid, and sputum confirmed the presence of cryptococci.

  • Enzyme-Linked Immunosorbent Assay (ELISA) for Human Immunodeficiency Virus (HIV) antigen was positive.
  • Histological findings in bone marrow, including granulomas, are indicative of opportunistic infections.
  • Implications:

    • Disseminated cryptococcosis in this patient highlights the importance of considering opportunistic infections in HIV-positive individuals.
    • Bone marrow examination is an effective method for diagnosing opportunistic fungal and mycobacterial infections in patients with unexplained fever, anemia, or thrombocytopaenia.
    • Early diagnosis and management of cryptococcosis are critical for improving outcomes in patients with HIV/AIDS.
