Abstract:
Histoplasmosis, also called as Darling's disease, is caused by the dimorphic fungus, Histoplasma capsulatum. In India, several cases of histoplasmosis have been reported since 1954, but in only a few cases could the diagnosis be confirmed by fungal culture. Disseminated histoplasmosis in adults is often associated with immunosuppression, as in human immunodeficiency virus (HIV) infection. Oral lesions are seen in 30-50% of the patients. Here, we are reporting two histoplasmosis cases, one with disseminated histoplasmosis with extensive skin and oral lesions in a known HIV-positive patient and the second case presenting with ulcer of the tongue, found to be HIV positive on investigation. It is important to consider histoplasmosis as one of the differential diagnosis of oral lesions in HIV-infected individuals.
Insights
Histoplasmosis, a fungal infection caused by Histoplasma capsulatum, can present with oral lesions, especially in individuals with human immunodeficiency virus (HIV). Early diagnosis and consideration of this infection are crucial for effective management.
Area of Science:
- Mycology
- Infectious Diseases
- Dermatology
Background:
- Histoplasmosis, caused by Histoplasma capsulatum, is endemic in certain regions.
- Disseminated histoplasmosis frequently occurs in immunocompromised individuals, particularly those with HIV.
- Oral manifestations are common in histoplasmosis patients, affecting 30-50%.
Observation:
- Two cases of histoplasmosis in India are presented.
- Case 1: Disseminated histoplasmosis with extensive skin and oral lesions in an HIV-positive patient.
- Case 2: Tongue ulcer in an HIV-positive patient, diagnosed as histoplasmosis.
Findings:
- Histoplasmosis diagnosis can be challenging, with limited culture confirmations in India.
- Oral lesions are significant indicators of histoplasmosis, especially in HIV-infected individuals.
- The study highlights the importance of considering histoplasmosis in the differential diagnosis of oral lesions in HIV patients.
Implications:
- Increased awareness of histoplasmosis as a cause of oral lesions in HIV patients is necessary.
- Prompt diagnosis and treatment of histoplasmosis can improve outcomes in immunocompromised individuals.
- Further research on histoplasmosis epidemiology and diagnostics in India is warranted.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
