Introduction Cellular angiofibroma is a benign mesenchymal tumor that is rare and has a good prognosis. However, preoperative distinction of cellular angiofibroma from malignant tumors is difficult. Case presentation A 77‐year‐old man complained of a left inguinal mass, which was a solid, painless, mobile tumor measuring approximately 40 mm and contacted with the left spermatic cord. Based on his age, the location and imaging findings, a preoperative diagnosis of myxoid liposarcoma was made. The patient underwent left high inguinal orchiectomy with complete resection of the tumor. Histologically and immunohistochemically, the tumor had no feature of malignancy. A postoperative diagnosis of cellular angiofibroma was made. The patient remains free of disease recurrence 12 months after surgery. Conclusion Cellular angiofibroma is a benign but rare tumor, which is sometimes difficult to distinguish from malignant neoplasms. Further studies are needed to accurately preoperatively diagnose this tumor.
Introduction Primary or metastatic urethral tumors are extremely rare. However, treatment strategies differ between primary and metastatic tumors. Therefore, establishing an accurate diagnosis is critically needed for initiating timely and appropriate therapy. Case presentation We describe the case of a 79‐year‐old man with prostate cancer treated with radiotherapy and androgen deprivation therapy. He presented with macroscopic hematuria as a symptom of anterior urethral tumor at follow‐up. Endoscopic tumor resection was performed. Hematoxylin and eosin staining showed adenocarcinoma component. Immunohistochemical staining revealed presence of metastatic prostate cancer to the urethra. Conclusion Regarding urethral tumors diagnosis, urologists should consider the possibility of metastasis from prostate cancer and perform immunohistochemical examination for establishing accurate diagnosis. Furthermore, if androgen deprivation therapy fails to suppress symptoms, radiotherapy or urethrectomy might be considered.
