[Frontal pyomucocele].

Mucoceles are strictly defined as chronic, expanding, mucosa-lined lesions of the frontal sinus and containing insipissated secretion. We present a 48-years-old female who complains right periorbital and frontal swelling of approximately 1,5 years duration. Radiological and exploratory findings confirm the diagnosis of infected mucocele (pyomucocele). Under general anesthesia an endoscopic sinus surgery was performed. One year later, the patient is alive and well with no evidence of primary disease.
