Posttraumatic Glabellar Mucocele: Case Report

Mucoceles are benign, expansile cystic masses covered by respiratory epithelium filled with mucus secreted by goblet cells interspersed in the ciliated mucosa. Mucoceles result from the accumulation and retention of the products of secretion, desquamation, and inflammation in cases where the drainage is obstructed. We present a case of a nasal mucocele that developed in a 50-year-old man, possibly related to a craniofacial trauma that had occurred 24 years earlier. This is an unusual case of posttraumatic glabellar mucocele with subcutaneous extension and nasal bone erosion without any neurologic or ophthalmologic involvement.
