Summary
Two patients with unusual skin and mucosal histoplasmosis were diagnosed via biopsy and culture, overcoming challenges in differentiating from cancers and tuberculosis. Both responded well to amphotericin B treatment.
Area of Science:
- Mycology
- Infectious Diseases
- Dermatology
Background:
- Histoplasmosis typically presents with pulmonary symptoms, but atypical cutaneous and mucosal manifestations can occur.
- Environmental exposure is a key factor in histoplasmosis transmission, often linked to soil contaminated with bat or bird droppings.
Observation:
- Two patients presented with significant skin and mucosal lesions, deviating from common histoplasmosis presentations.
- Differential diagnosis was complicated by the need to exclude neoplasms, lymphomas, leukemia, and tuberculosis due to lesion appearance.
Findings:
- Biopsy and culture were crucial for accurate histoplasmosis diagnosis in these atypical cases.
- Both patients showed positive therapeutic outcomes following treatment with amphotericin B.
Implications:
- Highlights the importance of considering histoplasmosis in patients with unexplained skin and mucosal lesions, even without typical respiratory symptoms.
- Emphasizes the diagnostic utility of biopsy and culture for challenging histoplasmosis cases.
- Confirms the efficacy of amphotericin B in treating severe or atypical histoplasmosis presentations.
