title: Nodular fasciitis on the zygomatic region: a rare presentation.
abstract: Nodular fasciitis is a benign tumor, resulting from reactive proliferation composed of fibroblastic/myofibroblastic cells. Due to its rapid growth and high cellularity it may be mistaken for sarcoma. Despite the possibility of spontaneous regression, excision is the treatment of choice. A 24-year-old female patient presented with a nodule on the zygomatic region with 3 months of evolution. Excisional biopsy was performed. Histopathological examination associated with immunohistochemical markers HHF35, AML and Ki-67 allowed diagnostic confirmation. The main relevance of the case presented is its rare location, suggesting its inclusion among the differential diagnoses of tumor lesions on the face.
