Zusammenfassung:The purpose of the present study was to increase the knowledge of angiomyofibroblastoma (AMF)-like tumors in males by describing the second case of this rare lesion in the Chinese population with a long period of follow-up and by reviewing the literature. AMF-like tumor is a rare, circumscribed, slow-growing mesenchymal tumor that occurs predominantly in the vulva, perineum and pelvis of females. The present report presents a case of left scrotal AMF-like tumor in a 37-year-old male. Complete surgical excision was performed. The tumor was composed of spindle-shaped cells and small vessels proliferating in the edematous stroma. Immunohistologically, the tumor cells stained positive for smooth muscle actin and negative for S-100, CD34 and actin. Following seven years of follow-up the patient was asymptomatic and no evidence of tumor was found. In addition, the current literature was reviewed and the characteristics of this tumor were summarized. AMF-like tumors must also be distinguished from spindle cell lipoma, solitary fibrous tumor and aggressive angiomyxoma.
