Scrotal leiomyoma is a benign tumor derived from the scrotal dartos muscle; it is rare in clinical findings. The cause of the disease is not yet clear. Here, we present the case of a patient with no typical clinical features, but with some typical pathological changes. A middle-aged male patient saw a doctor for paroxysmal itching and burning of the scrotum. The physical examination revealed 3 × 5-cm(2), ill-defined, pink plaques, an uneven surface, and basal infiltration with pigmentation defects in the center. Pathology results showed dermal spindle cells in nodular hyperplasia. The nucleus was round at both ends, a perinuclear halo could be seen, and staining was positive for actin and negative for S100. Therefore, the diagnosis of scrotal myoma was made.
阴囊平滑肌瘤是一种起源于阴囊肉膜肌的良性肿瘤；临床发现较为罕见。该病病因尚不清楚。在此，我们报告一例无典型临床特征但有一些典型病理变化的患者病例。一名中年男性患者因阴囊阵发性瘙痒和烧灼感前来就医。体格检查发现一个3×5厘米²、边界不清、粉红色的斑块，表面不平整，中央有色素沉着缺陷的基底浸润。病理结果显示真皮梭形细胞呈结节状增生。细胞核两端呈圆形，可见核周晕，肌动蛋白染色阳性，S100染色阴性。因此，诊断为阴囊肌瘤。
