- Abstract
Introduction: Desmoid tumors refer to a histologically benign but locally invasive lesions arising from musculo-aponeurotic structures and are associated with a high local recurrence rate. Among extra-abdominal desmoids only 11-15% arise in head and neck. Desmoid tumors arising in the temporal muscle are exceedingly rare; to our knowledge only one such tumor has been reported in the literature. Case Report: A 47-year-old female patient presents with pain in the right side of the head since 8 years. Examination revealed a solitary, firm mass measuring 3 x 3 cm which was tender on palpation and associated with restricted mouth opening. Computed tomography (CT) revealed bony defect at the right temporal region with small bony fragment and soft tissue swelling extension intracranially. Histopathology showed fibrous connective tissue stroma consisting of dense bundles of collagen fibers and fibroblasts with flattened nucleus. Infiltration of the lesion into the surrounding muscle fibers, separation and degeneration of muscle fiber bundles are seen by using phosphotungstun acid-hematoxylin stain (PTAH). Extra-abdominal fibromatosis (desmoid tumor) features were confirmed by immunohistochemistry markers like Vimentin, Ki-67, S-100, Desmin and Myogenin where tissue showed positivity to vimentin and focal positivity to Ki-67. Conclusion and Summary: This case report describes the rare occurrence of desmoid tumor in the temporal muscle. These lesions are histologically benign but locally invasive and are associated with a high local recurrence rate. The purpose of this case report is to recognize the importance of early diagnosis and prompt treatment of such cases.
