A Case of Nasal Desmoid Tumor / 대한이비인후과학회지

ABSTRACT

Desmoid fibromatosis is a very slowly growing benign fibroblast tumor. Locally aggressive and non-metastasizing, it is a well-differentiated, unencapsulated monoclonal myofibroblastic proliferation that has a tendency for local invasion and recurrence. About 15% of all desmoidtype fibromatosis develops within the head and neck. The majority of head and neck desmoid tumor is located in the neck, but less frequently in the face, scalp, oral cavity, mandible, paranasal sinuses, orbit, ear and other structures. We report a very rare case in a 55-year-old female of a desmoid fibromatosis arising from the lateral nasal wall of anterior portion of uncinated process. We discuss the clinicopathologic features and successful treatment of nasal desmoid tumor with a literature review.
