Epidemiological and Histopathological Profile of Gastric Adenocarcinoma at Brazzaville University Hospital

Introduction: Gastric adenocarcinoma is the most common gastric malignancy (over 90% of gastric cancers) and remains a global public health problem. The aim of the study was to determine the epidemiological and histopathological aspects of gastric adenocarcinoma in Brazzaville. Material and Methods: The epidemiological and histopathological profile is determined through a descriptive study, collecting retrospective data spread over a period of 11 years (January 2008- December 2018), based on consultation of the departmental histology registers. pathological anatomy and cytology. For each case, age, sex, location, pTNM stage, location and histological type were collected. Results: 93 histologically confirmed gastric adenocarcinomas were collected during the 11-year period. The mean age of the patients was 54.5 years. The sex ratio was 2 in favor of men. The antral and fundal localization were more frequent (74.2% and 20.4% respectively). Of the 2 operative parts collected, one was T2N1 and the other T1N0. Tubular adenocarcinoma was the most common histologic type (51.6%), followed by independent cell adenocarcinoma (34.4%), papillary adenocarcinoma (11.8%), and mucinous adenocarcinoma (2, 2%). Conclusion: gastric tubular adenocarcinoma was the most common histological type in Brazzaville. Key words: epidemiology, gastric adenocarcinoma, histological type.

Digital Papillary Adenocarcinoma: Case of a Rare Malignant Cutaneous Tumor of the Eccrine Sweat Gland

Digital papillary adenocarcinoma (DPA) is a rare cutaneous tumor originating from the eccrine sweat glands. These lesions occur almost exclusively on the digits of the hands and feet, where there is a high concentration of eccrine glands. The diagnosis is made histologically, and the course of the malignancy tends to be very aggressive with high rates of recurrence and early metastasis at the time of diagnosis. Due to the low incidence of these lesions, there have been minimal objective data from clinical studies to recommend specific treatment strategies. Wide local excision versus digital amputation proximal to the lesion has been debated for primary treatment, while there are no data to support routine implementation of adjuvant chemotherapy or radiation, despite its metastatic nature. This article presents a case of long-standing, previously undiagnosed DPA. The lesion appeared more inconspicuous on gross examination than other reports in the literature, and diagnosis was made with punch biopsy and confirmed postsurgically. To date, the patient has not had recurrence, although she is being monitored for potential metastatic deposits in her lungs. Clinical dermatologists should be aware of the high mortality burden this lesion may inflict if left undiagnosed or mistreated.
