Vocal fold cryptococcal granuloma: A rare occurrence in immunocompetent patient

INTRODUCTION AND IMPORTANCE: Cryptoccous infection or cryptococcosis is a severe opportunistic infection occurring mainly in immunocompromised patients. Laryngeal cryptococcus infection is rare. In an immunocompetent patient, inhaled corticosteroid was reported to be a possible risk factor.

CASE PRESENTATION: We discuss a case of right vocal fold cryptococcus infection in a healthy, immunocompetent 71-year-old man with no history of inhaled corticosteroid, presented with hoarseness and intermittent aspiration symptom for 1 year duration. Further examination showed right anterior vocal fold mass with presence of right vallecular cyst.

CLINICAL DISCUSSION: Patient underwent direct laryngoscopy, excision of right vocal fold mass and marsupialization of vallecular cyst. Histopathological examination revealed cryptococcal infection. Patient subsequently treated with oral fluconazole 400 mg daily for 6 months. To date, hoarseness and aspiration symptoms have resolved.

CONCLUSION: We are sharing our experience in managing laryngeal cryptococcus infection in an immunocompetent patient where the associated risk factors discussed in previous literatures are absent.
