Abstract: Introduction: Intraductal carcinoma is often associated with high-grade, high-stage adenocarcinoma. Its frequency is variable and it is considered a poor prognostic factor. In our context, when prostatic carcinoma is diagnosed, pathologists do not always report the presence of this anatomopathological entity. We therefore conducted a study to determine the epidemiological and anatomopathological profile of patients with this lesion in Dakar. Materials and Methods: This is a retrospective descriptive study covering a 1-year period from January to December 2022. It focused on cases of intraductal carcinoma diagnosed among prostatic carcinomas collected in the anatomopathology laboratories of Hôpital Général Idrissa Pouye (HOGIP) and Hôpital Militaire de Ouakam (HMO). It was based on archives of anatomopathological reports, blocks and slides. A total of 200 cases of prostatic carcinoma were collated and reviewed to identify those presenting with intraductal carcinoma according to the diagnostic criteria of Guo and Epstein. Results: 87 cases of intraductal carcinoma were found, representing 43.5% of prostatic carcinomas. The mean age was 71 years. Patients in their seventh decade were the most represented, i.e. 42.5%. The majority of samples examined were biopsies (72.4%). The mean PSA level was 965.91 ng/ml, with extremes ranging from 0.03 to 10,000 ng/ml. Histologically, 96.5% of cases (N = 84) were invasive prostatic carcinoma. Gleason score 8 (4 + 4) was the most common, accounting for 42.53% (N = 37). On average, the study found four (04) foci of intraductal carcinoma per specimen, with extremes ranging from 1 to 30. Dense cribriform architecture accounted for 78.16%, loose cribriform for 11.5%, solid for 8.04% and micropapillary for 2.3%. Six cases (6.9%) showed foci of comedonecrosis. The vast majority of radical prostatectomies (87.5%) were classified as pT3. Node invasion and perineural sheathing were observed in 12.5% and 52.32% of cases respectively. Conclusion: Intraductal carcinoma is a poor prognostic factor that must be systematically reported in the anatomopathological report. In Senegal, it is often associated with advanced stage, high-grade carcinoma and high PSA levels.
