Resumo: Nodular fasciitis (NF) is a rare non-malignant rapidly growing, self-limited myofibroblastic/fibroblastic soft tissue tumor. This lesion may cause differential diagnostic problems due to the lack of specific histopathological characteristics and, mainly, due to its histological appearance that resembles mesenchymal neoplasms. A 27-year-old female patient sought care due to a complaint of a firm and rapid painless swelling in the tongue. After an excisional biopsy, the histopathological evaluation of hematoxylin-eosin stain showed skeletal muscle tissue involving a well-delimited lesion with rich cellularity, consisting of spindle cells, with relatively uniform nuclei over a fibrous stroma. The immunohistochemistry panel was used as a complementary diagnosis procedure and included INI1, S100, EMA (MUC1), DESMIN, AE1-AE3, AML, and CD34. Based on clinical, histopathological, and immunohistochemical findings the present case was diagnosed as NF. Comprehensive knowledge of this entity is essential for adequate therapy avoiding unnecessary aggressive treatment
