ABSTRACT

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.

ABSTRACT

BACKGROUND: The human immunodeficiency virus (HIV) pandemic has brought about a resurgence in tuberculosis (TB), especially in developing countries. Previous studies on TB lymphadenitis (TBLN) in South-Eastern Nigeria were done before the advent of the HIV pandemic making a review pertinent. AIM: To evaluate the role of TBLN as a cause of superficial lymphadenopathy in the post-HIV/acquired immune deficiency syndrome (AIDS) era of South-Eastern Nigeria. MATERIALS AND METHODS: This is a 15 years (2000-2014) retrospective review of all superficial lymph node biopsies (SLNBs) received at the Department of Morbid Anatomy, University of Nigeria Teaching Hospital, Ituku-Ozalla Enugu, Nigeria. RESULTS: One hundred and seventy-two cases of TBLN were identified in this study constituting 14.6% (172/1,180) of SLNBs received at our Hospital's Morbid Anatomy Department during the 15 years period under review. Twenty-eight cases of TBLN were clinically screened for HIV, 23 of which tested positive, representing 82.1% (23/28) of clinically screened cases. Acid fast bacilli demonstration was positive in 15.1% (26/172) of cases using Ziehl-Neelsen stain. 48.8% (84/172) of TBLN cases were males, and 51.2% (88/172) were females with most (22) cases received in 2012 and least (5) cases in 2000. Most TBLN occurred in the 21-25 years age group with a total of 21.5% (37/172) of cases and a male to female ratio of 1:1.5 The most common biopsy site for TBLN was the cervical group followed by the axillary and inguinal groups with 73.8% (127/172), 14% (24/172), and 4.7% (8/172) of cases, respectively. CONCLUSIONS: There is a remarkable decline in the prevalence of TB lymphadenitis in South-Eastern Nigeria indicating a change in trend from the pre- to the post-HIV/AIDS era with slightly more females now presenting with TBLN and most TB lymphadenitis patients now presenting with associated HIV/AIDS disease. There is an urgent need to provide modern diagnostic facilities in our medical laboratories.

ABSTRACT

Primary synovial sarcoma is a very rare tumor of the mediastinum, which is unreported in the entire subcontinent of West Africa, and presents daunting challenges from diagnosis to management with lack of standard management strategies. We present a case of primary monophasic synovial sarcoma of the anterior mediastinum, in a 22-year-old Nigerian lady who presented with cough, chest pain, and pleural effusion. Chest X-ray (CXR) and computed tomography on admission showed a left-sided huge mass in the left anterior mediastinum with no metastasis to the contralateral pleural cavity. Complete resection of the mediastinal tumor was done and histologic and immunohistochemical analyses confirmed a diagnosis of monophasic synovial sarcoma. However, 10 months postoperation she represented with chest pain, productive cough and a repeat CXR showed multiple left pulmonary nodules. She received two cycles of docetaxel and gemcitabine chemotherapy, but declined further treatment until her demise 8 months later.

ABSTRACT

Fungi are unusually rare causes of gastric perforation, with most cases of gastric perforation occurring as complications of peptic ulcer disease (PUD), nonsteroidal anti-inflammatory drugs (NSAIDs) and gastric neoplasms. Here, we report the case of a 70-year-old Nigerian male who presented with severe epigastric pain, with no associated history of PUD, NSAIDs use or gastric neoplasm. An emergency exploratory laparotomy was performed and a gastric perforation was discovered and repaired. Histopathological examination of the gastric perforation edge biopsy revealed an intense Candida growth consisting of numerous fungal spores and hyphae invading and destroying the gastric wall. He was subsequently treated with fluconazole antifungal and discharged home after an uneventful postoperative period.

ABSTRACT

Bronchial carcinoid tumors (BCTs) are an uncommon group of lung tumors. They commonly affect the young adults and the middle aged, the same age group affected by other more common chronic lung conditions such as pulmonary tuberculosis. Diagnosis is commonly missed or delayed due to a low index of suspicion. Surgery is the mainstay of treatment with an excellent outcome. There are many reports of this rare group of tumors in the Western and Asian regions. The only report around our sub-region is a post mortem report of an atypical variant. We wish to report a case of the typical variant and increase our index of suspicion. A 25-year-old male presented with a 4 years history of cough and haemoptysis. He was repeatedly treated for bronchial asthma and pulmonary tuberculosis with no improvement of symptoms. Chest X-ray and chest computed tomography scan revealed a left upper lobe tumor. Histology reported a typical variant of BCT which was confirmed by immunohistochemistry. He had a left upper lobectomy and has done excellently well thereafter. A high index of suspicion is needed to reduce the risk of missing or delaying the diagnosis.
