ABSTRACT
Primary carcinoma of the fallopian tube is the rarest cancer of the female genital tract with an incidence of 1% all gynecologic tumors Moreover, adenocarcinoma in situ of fallopian tube accounts for approximately 1% of primary fallopian tube cancer. Ovarian cancer and primary carcinoma of the fallopian tube are similar in many aspects. Both carcinomas show an increase incidence among nulliparous women, are often of serous papillay histology, and they have not only a poor pronosis with stage and residual tumor size as important prognostic factors, but also respond to paclitaxel-based treatment. Nevertheless, presenting symptoms are variable and nonspecific, so pre-operative diagnosis of fallopian tube carcinoma is seldom made. We have experiened a case of primary adenocarcinoma in situ of fallopian tube and reported with brief review of literature.
