Fibrous obliteration of appendix9/3/2023 Since it was first characterized in 1893, this condition has been characterized as either congenital or acquired. If DA is discovered early with non-invasive imaging, surgical excision should be performed prophylactically as an association with an increased risk of perforation and neoplastic progression has been found.ĭiverticulosis of the appendix (DA), or appendiceal diverticular disease (ADD), is a rare occurrence with an incidence ranging from 0.004% to 2.1%. This may be the first case of diverticulosis of the appendix with FO in the English medical literature. An extensive literature search was performed, which revealed no other cases of FO of appendiceal diverticula. We suspect the chronic nature of her disease course may have led to the FO of the diverticulum. The histologic evaluation of the specimen demonstrated a diverticulum at the distal end of the appendix with FO of the lumen. The patient underwent laparoscopic appendectomy for suspicion of malignancy. We report a case of a 75-year-old female with a history of chronic, intermittent abdominal pains who presented to the general surgery clinic after an abnormal thickening of the appendix was discovered on abdominal and pelvic computed tomography imaging. Fibrous obliteration (FO) is a histologic finding indicative of cellular proliferation secondary to relapses of subclinical inflammatory processes. Some cases are discovered after presenting with similar symptomatology to acute appendicitis, whereas other cases may be completely silent. The different incidence in the pathologic findings at both places may suggest that patients at the CHPR have a delayed request of medical attendance.Diverticulosis of the appendix (DA) is rare and frequently found incidentally. Early lessions of appendicitis are better recognized and what is most important, carcinoid tumors located outside the tip can be diagnosed. Conclusions: the longitudinal method of studying the cecal appendix allows a better recognition of many lessions that might otherwise be overlooked. The CHPR cases had less normals and early lesions than the private place, as well as more cases with periappendicitis. 21 cases of carcinoid tumors were found most of them located at the middle third of the organ, with a median size of 7 mm almost all the cases had concomitant appendicitis and most of the patients were adolescent females. ![]() Parasites (mainly enterobius vermicularis) where found in 7% of the cases studied in the late years. 7 cases were fibrous obliteration of the lumen. 11 cases were undetermined granulomatous appendicitis. 1.519 were normal specimens 1.317 were early appendicitis 502 were diffuse appendicitis without priappendiceal inflammation and finally 7.047 were appendicitis with transmural inflammation and periappendicitis. Results: a total number of 10.424 cecal appendices were gathered 6705 from CHPR and 3.719 from the private laboratory. The specimens were longitudinally sectioned after formalin fixation and the whole longitudinal cut surface was embedded for histological examination. ![]() Methods: all cecal appendices were studied by the authors and the same method was applied. 2) To compare the results in both places. Objectives: 1)To review the pathologic findings in pediatric cecal appendix specimens studied in a 20 years period (1983-2003) at the Pereira Rossell Hospital (CHPR) and also at a private laboratory in the same period. Enfermedades del apéndice cecal: Revisión de 10.424 casos en un período de 20 años.
