Introduction: The hyalinizing spindle cell tumor with giant rosettes is a neoplasia characterized by both histologic components, one of which is cellular, with spindle-shaped elements and the second represented by well defined almost acellular islands filled with hyaline material surrounded by round to oval cells, which shows an unusual immunohistochemical profile and uncertain histogenesis. Objective: Educate pathologists and clinicians about this tumor, its presentation and differential diagnosis. Methods and results: A case of a 42 year old woman with a mass located in the inguinal region, with progressive growth (1 year), surgically resected and histopathology reported as Hyalinizing spindle cell tumor with giant rosettes according to morphological, immunohistochemical findings correlates with its location and clinical. Conclusion: It is necessary to expand awareness about this condition and thus obtain a proper assessment of histological prognostic criteria, clinical behavior and treatment.
