Xanthogranulomatous cystitis (XC) is a very rare urinary bladder condition, of unknown etiology. It may mimic bladder malignancy; therefore, histopathologic assessment is crucial in diagnosis. We report a case of a 38-year-old female who presented with persistent, painless hematuria and a strong consideration of bladder malignancy clinically and on cystoscopy. However, on histopathologic evaluation, the rare diagnosis of XC was made. She received a course of antibiotics and has remained asymptomatic after four months of follow-up. To the best of our knowledge, this is the first reported case of XC in Nigeria and Africa.
Introduction: Pituitary adenomas [PAs] constitute the third most common primary intracranial tumours, with a wide prevalence rate of 1% to 40%. Histologic (H & E) classification into acidophilic, basophilic and chromophobic adenomas have little clinical relevance but WHO recommended immunohistochemical subclassification has both therapeutic and prognostic significance. This immunohistochemical subclassification has not been done in our environment, making it imperative for us to evaluate the patterns in our environment. Aim: To determine the immunohistochemical patterns of PAs in Southeastern Nigeria. Materials and Methods: This was a 10-year retrospective review of all PA biopsies received at University of Nigeria Teaching Hospital Enugu, Memphys Hospital for Neurosurgery Enugu and Grace Pathology Consults Enugu, Nigeria. The age, sex, histologic, immunohistochemical subtypes and biopsy size of all diagnosed PAs were analyzed using Statistical Package for Social Sciences (SPSS) version 20 (New York: IBM Inc.) and the results were expressed in descriptive statistics. Results: One hundred cases of PAs were identified in this study constituting 19.6% of all primary intracranial tumors received at our study centers during the period under review. There were 45 (45.0%) females and 55 (55.0%) males giving a female to male ratio of 1:1.2, and a mean age of 45.3 years. The commonest histologic type was acidophilic adenoma (49.0%), followed by basophilic (40.0%) and chromophobic (11.0%) adenomas. Null cell adenomas were the most common immunohistochemical subtype (44.0%), followed by PRL-secreting adenomas (27.0%). Others were Luteinizing hormone (LH) − 13 (13.0%), follicle stimulating hormone (FSH) − 7 (7.0%), growth hormone (GH) − 3(3.0%), TSH − 2(2.0%) and ACTH − 1(1.0%) adenomas. Conclusion: PAs predominate amongst males, occurring mostly in the middle age groups in Southeastern Nigeria. Null cell adenoma is the commonest immunohistochemical subtype followed by PRL-secreting adenomas. Routine immunohistochemical characterization is required for accurate diagnosis and optimal patient care.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
