A unique case of a mixed müllerian tumor in a 33-year-old woman is presented. On gross examination of the hysterectomized specimen, well-circumscribed nodules, the largest measuring 3 cm in diameter, were found in the lower uterine segment. Microscopic examination revealed that the lesion was composed of a malignant glandular epithelium and a spindle cell stroma containing a smooth muscle. The atypical gland had deeply infiltrated into the normal myometrium and showed a squamous differentiation. This tumor should be differentiated from a benign mixed müllerian tumor, including an atypical polypoid adenomyoma, an adenofibroma, and an adenomyoma.
本文报告了一例33岁女性的混合性苗勒管肿瘤的独特病例。对子宫切除标本进行大体检查时，在子宫下段发现了边界清晰的结节，最大直径为3厘米。显微镜检查显示，病变由恶性腺上皮和含有平滑肌的梭形细胞基质组成。非典型腺体已深深浸润到正常子宫肌层，并表现出鳞状分化。该肿瘤应与良性混合性苗勒管肿瘤相鉴别，包括非典型息肉样腺肌瘤、腺纤维瘤和腺肌瘤。
