Introduction: This is a retrospective study of all gastrointestinal tract (GIT) specimens seen in University of Uyo Teaching Hospital over a 10-year period from January 1, 2008 to December 31, 2017. Materials and Methods: Data were extracted from the departmental registers, patient request forms, and duplicate copies of histology reports of all cases seen. Results: GIT specimens accounted for 4.3% of all specimens. Majority of them were inflammatory lesions, distantly followed by malignant lesions. Inflammatory diagnoses were seen in all parts of the GIT with the appendix accounting for 76.3% of the inflammatory lesions. Appendicitis was the most common diagnosis, while negative appendix was the second most common diagnosis. In all sites except the anus, males were affected more than females in a sex ratio of 1.5:1. Age groups 10–39 years accounted for 79.9% of all appendix inflammatory lesions, with age group 20–29 contributing the highest. Age groups 40–59 had most gastritis cases. Age group 50–59 years accounted for most malignant lesions, with the majority seen in the colon. Adenocarcinomas distantly followed by squamous cell carcinomas were the most common histologic malignant diagnoses made. Conclusion: The pattern of GIT lesions seen in our institute has been documented and this will serve as a baseline data for future local studies.

Hidradenoma papilliferum is a known example of adnexal skin tumours with apocrine differentiation. It is a rare benign tumour which tends to arise from areas with rich concentration of aporine glands such as anogenital region, vulval, perineal, axillae, and periumbilical areas. In this report, the tumour was found in the upper outer quadrant of left breast, being one of the ectopic sites for this tumour. Contrary to most reports where male preponderance was popular for ectopic hidradenoma papilliferum, the patient in this report is a 71-year-old female. Considering the location of this tumour in this report, the likely histopathological differential diagnoses such as tubular apocrine adenoma, clear cell (apocrine) adenoma, lipoma, intraductal papilloma and papillary carcinoma of the breast should be considered for exclusion. This is the first reported case of a giant ectopic hidradenoma papilliferum of the breast in a Niger Delta region of Nigeria which also highlights the role of fine needle aspiration and cytology in the diagnosis of breast lesions.
