“…6 Moreover, CAF was revealed to have no area of diffusion restriction on DWI, which is mainly noted in malignant tumors. 7,8 These characteristics are different from those of our patient. Therefore, MRI findings are non-specific, and preoperative distinction of CAF from malignant tumors is difficult.…”

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.

“…Only sporadic case reports of angiomyofibroblastoma-like tumors exist in the literature. 21,22 Histopathologically, the tumor is composed of spindle-shaped cells arranged around numerous small to medium-sized vessels in abundant myxoid stroma and dense collagen fibers. On immunohistochemical staining, the spindle-shaped cells are positive for CD34 but negative for desmin, smooth muscle actin, and S-100 protein.…”
