Detection of Serous Tubal Intraepithelial Carcinoma along with High Grade Serous Carcinoma of Both Ovaries.

High-grade serous carcinoma (HGSC) of ovary is the commonest of all ovarian malignant tumours and is associated with high mortality rate. Serous tubal intraepithelial carcinoma (STIC) is believed to be the precursor lesion. In literature, only 40-50% of HGSC shows concurrent STIC, even after thorough sampling. We, herein, present a case of a 40-year female, who underwent staging laparotomy for bilateral ovarian carcinoma. She was diagnosed as HGSC of both ovaries. Left ovary capsule was focally ruptured. Peritoneal washings showed metastatic carcinoma. Provisional FIGO stage was IC. During sampling, concurrent finding of STIC was documented in right fallopian tube. No invasive carcinoma was present in both entirely submitted fallopian tubes. Key Words: High grade serous carcinoma, Ovary, Serous tubal intraepithelial carcinoma, TP53.
