A case is reported where displaced non-neoplastic ovarian granulosa cells within the fallopian tube mimicked a small cell carcinoma. This peculiar phenomenon of displaced granulosa cells has been described previously in the ovary as a rare diagnostic pitfall which may be misinterpreted as metastatic carcinoma. This is believed to be the first documentation of its occurrence in the fallopian tube. Awareness of this rare phenomenon and immunostaining for markers of sex cord differentiation assist in diagnosis and in preventing a false positive diagnosis of malignancy.
本文报告了一例输卵管内移位的非肿瘤性卵巢颗粒细胞酷似小细胞癌的病例。这种颗粒细胞移位的特殊现象先前在卵巢中已有描述，是一种罕见的诊断陷阱，可能被误诊为转移性癌。据信这是该现象在输卵管中发生的首次记录。认识到这种罕见现象并进行性索分化标志物的免疫染色有助于诊断，并防止恶性肿瘤的假阳性诊断。
