From misdiagnosis to precision therapy: A case of scedosporium apiospermum pneumonia in an immunocompetent host.

Scedosporium apiospermum, a rare but increasingly recognized fungal pathogen, poses significant diagnostic and therapeutic challenges. Traditionally associated with immunocompromised individuals. We present a case of S. apiospermum lung disease in an immunocompetent patient, initially misdiagnosed as tuberculosis due to overlapping clinical and radiological features. Accurate diagnosis was achieved through bronchoscopy and fungal culture, leading to successful treatment with antifungal therapy. This case highlights the importance of considering S. apiospermum in the differential diagnosis of refractory lung infections, even in patients without obvious risk factors. Additionally, a brief literature review sheds light on the epidemiology, clinical presentation, and treatment strategies for this pathogen, emphasizing its clinical relevance and the need for heightened awareness. By showcasing this case, we aim to contribute to the understanding of S. apiospermum lung disease and its management, inspiring further research and improving patient outcomes.
