Abstract

In this case, a 66-year-old female patient presented with the chief complaint of abdominal distention. Computed tomography and magnetic resonance imaging revealed no enlarged ovaries or obvious primary lesions; however, massive ascites and peritoneal disseminated nodules were observed. Ascites cytology revealed adenocarcinoma and immunohistochemical findings suggested serous carcinoma. The patient then underwent tumor reduction surgery after preoperative chemotherapy for suspected Stage IIIC primary peritoneal carcinoma. Postoperative histopathology revealed carcinoma consisting mainly of high-grade serous carcinoma (HGSC) and sarcoma. In addition, serous intraepithelial carcinoma (STIC) of the fallopian tube was observed in the fimbriae of the left fallopian tube. Recently, it has been noted in the literature that most cases of peritoneal carcinoma are metastases or dissemination of carcinoma originating from the fimbriae of the fallopian tube. This is a rare case of peritoneal carcinosarcoma with STIC, and its report leads to a better understanding of the disease's features and possible therapeutic approaches.

一例伴有浆液性输卵管上皮内癌的腹膜癌。
在本病例中,一名 66 岁的女性患者以腹胀为主诉。计算机断层扫描和磁共振成像显示卵巢没有增大,也没有明显的原发病灶;但观察到大量腹水和腹膜播散性结节。腹水细胞学显示为腺癌,免疫组化结果显示为浆液性癌。术前化疗后,患者接受了疑似 IIIC 期原发性腹膜癌的肿瘤缩小手术。术后组织病理学显示,癌细胞主要由高级别浆液性癌(HGSC)和肉瘤组成。此外,在左侧输卵管的缘膜上还发现了输卵管浆液性上皮内癌(STIC)。最近有文献指出,大多数腹膜癌病例都是源自输卵管纤毛缘的癌转移或扩散。这是一例罕见的伴有STIC的腹膜癌,报告该病例有助于更好地了解该疾病的特征和可能的治疗方法。
