Giant Submucosal Fibromatosis of the Base of Tongue Presenting as Paediatric Obstuctive Sleep Apnoea: A Rare Case Report

AbstractA nodular lesion of the tongue encompasses a range of conditions, from reactive to malignant. It can be challenging to diagnose when a solitary and firm submucosal mass appears in the oral cavity. Following an essential investigation protocol is necessary for reaching a definitive diagnosis. Leiomyomas are benign tumors that infrequently occur in the oral cavity and typically affect individuals between their forties and fifties. This case report presents a rare and unique case of a giant submucosal fibromatosis located at the base of the tongue in a 3-year-old child presenting with features of pediatric OSA. Immunohistochemical analysis revealed the positivity of tumor cells for beta-catenin and CD 34 aberrant expression, though SMA and STAT 6 were negative. The lesion was removed submucosally in toto and post-surgery the patient showed no symptoms and had no evidence of tumors during the one-year follow-up visit.
