We report a case of a leiomyomatous hamartoma located in the midline of the base of the tongue. The two-year-old girl had an asymptomatic pedunculated tubular tumour measuring 1.6 x 1.3 x 1.1 cms. The lesion was surgically excised, and histopathological examination disclosed a non-neoplastic mass composed of irregular arranged bundles of smooth muscle cells embedded in a fibrovascular stroma. The diagnosis was confirmed by immunohistochemistry with positivity for smooth muscle actin and desmin. Until now, only 19 cases have been reported in English-language literature.
我们报告一例位于舌根部中线的平滑肌瘤性错构瘤。该两岁女童有一个无症状的带蒂管状肿瘤，大小为1.6×1.3×1.1厘米。病变经手术切除，组织病理学检查显示为非肿瘤性肿块，由嵌入纤维血管基质中的不规则排列的平滑肌细胞束组成。通过免疫组织化学检测平滑肌肌动蛋白和结蛋白呈阳性，确诊得以证实。迄今为止，英文文献中仅报道了19例。
