Challenges in the Management of Massive Carotid Body Tumor.

The carotid body paraganglioma is a rare benign neoplasm arising from the chemoreceptor cells of the carotid bulb. The carotid body has the largest collection of paraganglia in the head and neck with 60-70% of head and neck paraganglioma. Paraganglia are clusters of cells originating from the neural crest with histological and cytochemical characteristics of neuroendocrine cells.

A Review of the Current Management of Intracranial Infections of Neurosurgical Importance.

Surgically treated intracranial infections are among the common disease entities seen in neurosurgical practice. Several microbiological agents such as bacteria and fungi have been identified as responsible for intracranial infection. It affects all age groups, though microbial agents and risk factors vary with age.

Respiratory Epithelial Adenomatoid Hamartoma: An Uncommon Differential of Nasopharyngeal Tumor.

Respiratory epithelial adenomatoid hamartoma (REAH) is an uncommon tumor-like lesion that has been reported within the nose, paranasal sinuses, and less frequently in the nasopharynx. While it is believed to be benign, its clinical presentation, radiological characteristics, and microscopic features may closely mimic more aggressive tumors of the upper respiratory tract, potentially leading to needless life-altering treatment. Prior to now, there had been no reported cases of this lesion in West Africa.

Poorly differentiated carcinoma with neuroendocrine features in two patients with sinonasal tumours: a report of two cases.

Neuroendocrine tumors can be described as rare, heterogeneous, epithelial tumours with principally neuroendocrine differentiation that can be harboured in the sinonasal cavities. Owing to the intermingling of its clinical, radiological and histopathological features, the diagnosis of poorly differentiated sinonasal carcinomas with neuroendocrine features is a daunting one. Many of these tumours have a poor prognosis.

Malignant Phyllodes Tumor: Report of Two Cases and Review of Literature.

Phyllodes tumuor (PT) is a rare biphasic breast neoplasm. It constitutes <1% of the entire tumours of the breast. Based on the World Health Organization's (WHO) proposal, premised on multiple histological features, phyllodes tumour is categorized into benign, borderline, and malignant breast neoplasms.

Histomorphological assessment of non-neoplastic renal diseases at autopsy: an institutional experience in Southwestern Nigeria.

Background: Autopsy remains an invaluable resource for medical education and establishing diagnosis of diseases that were missed prior to death. Many patients on admission in hospitals suffer kidney diseases that may contribute to their morbidity and/or mortality. The kidneys from autopsies provide opportunity to diagnose and understand some of these non-neoplastic renal lesions.

Histopathological profile of childhood thyroid carcinoma in Ibadan, Southwestern Nigeria.

Background: Thyroid carcinoma is a common endocrine malignancy. It is however rare in childhood and often occurs as a result of radiation exposure or inherited genetic mutations. Most childhood thyroid carcinomas are well differentiated.
