Cutaneous Pseaudallescheria Boydii Infection- Two Rare Case Reports

Pseudallescheria boydii, is a saprophytic fungi of increasing clinical importance which belongs to the genus Scedosporium. It is a rare cause of infection in humans. The prevalence of infection is more among immunocompromised patients and it is rarely seen among immunocompetent individuals. It causes broad spectrum of diseases including subcutaneous and soft tissue infection, pneumonia, brain abscess, endocarditis, sinusitis and disseminated infection. Here we report two cases of Pseudallescheria boydii in immunocompetent patients presented as subcutaneous swelling. Case 1 A 30 year old female presented with swelling over left elbow, which was clinically diagnosed as lipoma. Fine needle aspiration yielded pus like material. It was surgically debrided and tissue was sent for histopathological examination. Case 2 A 70 year old female presented with swelling over dorsum of right foot. On fine needle aspiration pus was aspirated. In both the cases on cytology, fungal elements showing septate hyphae with acute angle branching, intercalary and lateral conidia were seen in an inflammatory and necrotic background. Diagnosis was confirmed by Gomori methenamine silver stain and culture. On the basis of above findings diagnosis of Pseudallescheria boydii was made.
