By using the Coons indirect immunofluorescence technique, enkephalin-like immunoreactivity with a granular localization was observed in human adrenal medullary gland cells and pheochromocytomas. In two of the tumors and in a few adrenal gland cells, a somatostatin-like peptide could also be identified. Catecholamine cell types were visualized on adjacent sections with antisera to the synthesizi...
Over the last 30 years nuclear medicine imaging of the adrenal gland and its lesions has been achieved by the exploitation of a number of physiological characteristics of this organ. By seeking and utilising features which are quantitatively or qualitatively different from those of the adjacent tissues, functional depiction of the adrenal gland and its diseases, which in most cases retain the b...
BACKGROUND Adrenal abnormalities are often identified on imaging studies performed during the staging of patients presenting with a new malignancy or restaging of patients with a history of a malignancy. METHODS We reviewed the records of patients who underwent surgical resection of an adrenal mass identified in the setting of previously or newly diagnosed extra-adrenal malignancy. RESULTS ...
OBJECTIVE To review the clinical manifestations of phaeochromocytoma in a Hong Kong Chinese population. DESIGN Retrospective review. SETTING. Five public hospitals in Hong Kong. PATIENTS Seventeen patients with operated phaeochromocytoma between 1994 and 2003 were reviewed retrospectively. RESULTS Six patients (35%) were men, 11 (65%) were women. The mean age at presentation was 47 (range...
Although it is common to have extra-hepatic metastasis of hepatocellular carcinoma (HCC) at the time of presentation, it is extremely rare to have extra-hepatic metastatic HCC without a detectable primary in the liver. We report a unique case in which a patient presented with bilateral large adrenal masses which were subsequently proven to be metastases from HCC. However, there was no tumour se...
OBJECTIVE Testing for succinate dehydrogenase subunit B (SDHB) mutations is recommended in all patients with metastatic phaeochromocytomas and paragangliomas (PPGLs), but may not be required when metastatic disease is accompanied by adrenaline production. This retrospective cohort study aimed to establish the prevalence of SDHB mutations among patients with metastatic PPGLs, characterised by pr...
Carotid body tumor is a rare neoplasm, occasionally familial in occurence, is difficult to establish its malignancy histopathologically. In this paper, we report two cases seen in the same family. As far as our survey concerned present report on the familial incidence is the second in Japan. Case 1: I. K., 13 years old girl. She visited a hospital with complaints of the neck mass and low grade ...
The histological and histochemical features of a primary chemodectoma of lung are described and compared with previously reported pulmonary chemodectomata. The tumour is of interest because, although there is physiological evidence that chemoreceptors are present in the lung, they have not yet been located anatomically.
