OBJECTIVES Different approaches have been made to differentiate benignant from malignant cervical lymphadenopathy using ultrasound examination. Assessment of nodal status is essential in patients with head and neck carcinomas as it predicts prognosis and helps in the selection of treatment options. The present study was designed to evaluate the role of ultrasound in the assessment of malignant ...

E-cadherin, a member of the cadherin family, plays a major role in cell-cell adhesion of normal epithelium. Recent studies have demonstrated that heterogeneous expression, reduction or loss of E-cadherin is involved in invasion and metastasis of cancer cells. In this study, the localization of E-cadherin in the normal human kidney and the relationship between E-cadherin expression and histopath...

We report a case of Alexander's disease in a black South African boy of 9 years. The child presented with a grossly abnormal stooped posture, generalised weakness, and slurred nasal speech. Computerised tomography revealed diffuse low radio-density confined to the white matter, and enlarged ventricles. Cerebral biopsy confirmed the diagnosis. The histopathological and electron microscopic featu...

Histological changes in 20 Giardia positive duodenal biopsies (Group A) were compared with 50, Giardia negative duodenal biopsies (Group B), taken during the same period. Stool examinations in Group B were negative for Giardia. Surface epithelium, villous and crypt architecture and cellular infiltrates were examined and compared between the groups. Atrophic changes in the villi were more common...

Clinical features of high risk brain arteriovenous malformations (BAVMs) are well characterized. However, pathological evidences about the differences that are possessed by high risk patients are still lacking. We reviewed archived routine hematoxylin-eosin specimens from a total of 54 surgical treated BAVMs. The histopathological features in nidus were semi-quantitatively analyzed. We obtained...

Protoplasmic astrocytomas are uncommon in humans and animals. A 14-year-old, intact female German Shepherd dog presented with a history of ataxia of the pelvic limbs, left-side head torsion and hypermetric response of the right side for approximately 15 days. Neurological examination revealed the presence of cerebellar syndrome and paradoxical vestibular syndrome. Medical therapy was initiated,...

INTRODUCTION Pityriasis rosea is a sudden-onset and self limiting disease with specific skin rash. The exact etiology is still not clear. AIM To determine epidemiological, etiological, clinical and histopathological features in pityriasis rosea (PR). MATERIAL AND METHODS Fifty two patients (older than 18 years) with PR were included in this study. Patients were examined for epidemiological ...

Leprosy is a chronic disease caused by Mycobacterium leprae, highly incapacitating, and with systemic involvement in some cases. Renal involvement has been reported in all forms of the disease, and it is more frequent in multibacillary forms. The clinical presentation is variable and is determined by the host immunologic system reaction to the bacilli. During the course of the disease there are...

This study aimed to investigate the histopathological feature of sacroiliitis and to examine its relationship with imaging features using various imaging techniques. Computed-tomography (CT)-guided needle biopsy of the sacroiliac (SI) joints was performed in 36 patients with spondyloarthritis. Histopathological examination was performed on the samples and subjects were divided as with or withou...
