Zuckerkandl’s organ (ZK) is an extra adrenal para-ganglion and has the ability to express glial cell line derived neurotrophic factor (GDNF) and transforming growth factor (TGF). It is also a source of dopamine and norepinephrine. In the present study, the neuroprotective and restorative potential of ZK was studied by transplanting it into the striatum of adult rats either before or after the i...

Myelolipomas are rare, benign nonfunctioning tumors, most commonly found in the adrenal glands. At least 43 cases of extra adrenal myelolipomas have been reported, with at least 50% of these reported cases occurring in the presacral region. Herein we report a case of presacral myelolipoma managed laparoscopically.

Introduction. In patients with extra-adrenal malignancy, an adrenal mass necessitates investigating the possibility of metastatic tumor. Curable adrenal metastasis are considered as a rare event. Case report. A 52-year-old male suffering from lower esophageal adenocarcinoma with a solitary left adrenal metastasis is presented herein, who underwent concomitant transhiatal esophagectomy and left ...

Adrenal rest tumor in liver is a very rare tumor. It originates from an adrenal rest, which is derived from the aberrant adrenocortical tissue. Adrenal rest tumor is an ectopic collection of adrenocortical cells in extra-adrenal sites. This tumor may be hormonally active and manifest endocrine syndromes. But, most tumors are non-functioning and benign. Histologically, hepatic adrenal rest tumor...

INTRODUCTION Myelolipomas are uncommon, benign tumors composed of mature adipose tissue and hematopoietic elements. They mostly occur in the adrenal glands, but extra-adrenal myelolipomas have also been reported in other locations such as the presacral region, retroperitoneum, pelvis and mediastinum. Here, we present a case of an extra-adrenal myelolipoma in a rare site: the renal parenchyma. T...

Two behaviorally active hormones of the pituitary-adrenal system are adrenocorticotropic hormones (ACTH) and corticosterone, and their behavioral effects are facilitation and inhibition of performance of previously learned avoidance responses, respectively. Their uptake, distribution and effects on central nervous system are reviewed. Hypothalamic neurotransmitter control of corticotropin relea...

INTRODUCTION  Paragangliomas are neuroendocrine tumors that most commonly originate in the adrenal gland, a type that is called pheochromocytoma; however, 5-10% of paragangliomas are extra-adrenal and may arise in any area between the neck and pelvic region along the sympathetic nervous system. Those located in the head and neck comprise 3% of extra-adrenal tumors, with the majority originating...
