Desmoid tumor of the larynx complicating pregnancy: A case report

Desmoid tumors are locally invasive fibrous neoplasms that arise from muscu loaponeurotic structures. We report the first case of a desmoid tumor of th e larynx complicating pregnancy. At 21 weeks' gestation fiberoptic and indi rect otolaryngologic examination of the patient's larynx revealed a submuco sal tumor involving the left true vocal cord, ventricle of the larynx, and false vocal cord. Histopathologic examination revealed areas of extensive f ibrosis intermixed with degenerated vocal cord skeletal muscle. Despite a s ubtotal excisional biopsy, growth of the desmoid tumor continued during pre gnancy. Endoscopic evaluation 9 weeks post par turn revealed complete regre ssion of the tumor.
