A Case of Ethmoid Mucocele with Superimposed Fungal Infection / 대한이비인후과학회지

ABSTRACT

Mucocele is a benign, chronic, expansive and cyst-like lesion of the paranasal sinuses and contains mucoid secretions. The secretion is usually sterile, however, secondary bacterial infection may lead to the development of a pyocele. Mucocele with superimposed fungal infection is very rare. Only four cases have been reported in the literature, of which, two were allergic fungal sinusitis. It is very difficult to distinguish mucocele from fungal sinusitis, when etiher one is presented as a sinus mass, with radiologic findings alone. Only intraoperative and pathologic findings can tell the difference between the two diseases. Recently we experienced an anterior ethmoid mucocele which was treated with endoscopic sinus surgery and verified it histopatologically to be fungal sinusitis.
