Abstract
INTRODUCTION: Intrascrotal tumors are relatively rare. Differentiating benign intrascrotal tumors from malignant tumors is frequently difficult. Here, we report a case of benign fibrous pseudotumor following puncture of a hydrocele and loss of the left testis. CASE PRESENTATION: A 65-year-old man complained of a left hydrocele and underwent scrotal puncture three times. The patient had painful enlargement of the left scrotum and was diagnosed with a malignant tumor in his scrotum based on cytological results and imaging test findings, including ultrasonography, computed tomography, and magnetic resonance imaging. The patient underwent high inguinal orchiectomy; the patient was finally diagnosed with fibrous pseudotumor. CONCLUSION: Puncture of the scrotum may be considered a cause of fibrous pseudotumors.
