migration of cardiac neural crest cells into the pharyngeal arches and the pharyngeal and splanchnic mesoderm contributes to the development of the cardiac outflow tract. the adrenal cortex is derived from the splanchnic mesoderm. neuroblastoma is more prevalent in patients with congenital heart disease than in the general population, because both originate from embryonal neural crest-derived c...

INTRODUCTION Oncocytic neoplasms occur in several organs and are most commonly found in the thyroid, kidneys and salivary glands. Oncocytic neoplasms of the adrenal cortex are extremely rare and are usually non-functioning. CASE PRESENTATION We report the case of an adrenocortical oncocytic neoplasm with uncertain malignant potential in a 31-year-old man with Cushing's syndrome. The patient h...

Background: Gangliocytomas are rare neuronal tumors with an incidence of less than 1% all CNS neoplasms. They mostly seen in the pediatric age group, localizing within cerebral cortex, most often temporal lobe. Methods: We report a case intracranial gangliocytoma arising lateral ventricle adult patient. Our 66-year-old female patient started experiencing progressive generalized weakness, headac...

GH receptor (GHR) has been reported to express in both normal rat and human adrenals. However, no study examined GHR expression in diseased human adrenal cortex. We quantitated, with RT-PCR, GHR messenger RNA (mRNA) in both normal and diseased human adrenal cortex with the following results: GHR mRNA levels in four histologically normal, not steroid-stimulated, control adrenal cortices was 1.5-...

Introduction . Chronic pain syndrome in the development of malignant neoplasms has a complex polyethological character. The study pathogenetic mechanisms during growth transplanted tumor experiment can open up broad perspectives for creation new domestic analgesic drugs use oncology. Aim : To serotonin inactivation coefficient (SIC), ratio (S) and its main metabolite 5-hydroxyindolacetic acid (...

AIMS To investigate the immunohisto-chemical staining of normal, hyperplastic, and neoplastic adrenal cortex with a monoclonal antibody against alpha inhibin. Also, to determine whether immunostaining with this antibody is useful in differentiating between adrenal cortical neoplasms and other tumours involving the adrenal gland that might mimic them. METHODS Normal adrenal tissue (n = 20) and...

In human estrogen-dependent neoplasms such as breast, endometrioid endometrial, and surface epithelial-stromal ovarian carcinomas, intratumoral aromatase is considered to play important roles in converting circulating androgens derived from adrenal cortex and/or ovary to estrogens, possibly in association with 17 beta-HSD type 1 and estrogen sulfatase. Analysis of intratumoral aromatase in thes...

spindle cell neoplasms are defined as neoplasms that consist of spindle-shaped cells in the histopathology. spindle cell neoplasms can affect the oral cavity. in the oral cavity, the origin of the spindle cell neoplasms may be traced to epithelial, mesenchymal and odontogenic components. this article aims to review the spindle cell neoplasms of the oral cavity with emphasis on histopathology.  ...
