Introduction: Granular cell tumors are uncommon benign neoplasms. The head and neck is the most common site, usually localized to the anterior tongue. The larynx is rarely involved, representing 1.6% to 3.7%.
Case report: We present the case of a 31-year-old, non-smoking female, with a history of recurrent cysts in the pyriform sinus. She consulted for dyspnea. By physical exam, there were no specific findings in head and neck area. Cervical computed tomography demonstrated a tissular mass in the laryngeal area. Laryngoscopy showed a submucosal tumor of the aryepiglottic fold. A biopsy was performed. Histopathological examination revealed round or oval-shaped tumor cells with abundant eosinophilic granular cytoplasm. The nuclei are sometimes small and regular and sometimes hyperchromatic and pleomorphic. The tumor cells showed immunoreactivity for S100 protein and vimentin. The tumor was diagnosed as an atypical granular cell tumor.
Conclusion: Pathologists should be aware of this exceptional lesion. So, that the patient could have appropriate treatment.
