Introduction and importanceSpindle cell tumors in the paratesticular region are infrequent. Accurate diagnosis requires clinical assessment, pathological analysis, and immunohistochemical (IHC) analysis.Case presentationThe present study reports a 33-year-old male who presented with a painless mass in his right testis. The mass grew from the size of a marble to that of a tennis ball in two years. Physical examination and ultrasonography revealed a solid mass in the right paratesticular area. The patient underwent a right paratesticular tumor excision, without interfering the right testis. Histopathologic analysis showed spindle cell tumor appearance referring to inflammatory myofibroblastic tumor (IMT).Clinical discussionIMT, also known as inflammatory pseudotumor, is a rare and benign neoplasm that can occur anywhere. Diagnosis is challenging, because it mimics other neoplasms. Immunohistochemical profiles were decisive in concluding a definitive diagnosis. Treatment, on the other hand, depends on tumor burden and connectivity to other region.ConclusionSpindle cell tumors are very rare and can be treated with simple excision if no organ adhesion is detected. Therefore, right orchidectomy was not required in our case.
