Gallbladder paraganglioma

Gallbladder paraganglioma.

Gallbladder paraganglioma is a very rare tumor, and only a few cases have been reported. Most of these cases were asymptomatic and found incidentally during operation. Our case involved a 57-year-old female patient complaining of intermittent right upper quadrant pain. Preoperative imaging demonstrated a mass in the neck of the gallbladder. Laparoscopic cholecystectomy was performed, and a froz...

Mesenteric paraganglioma with gallbladder paraganglion nest

We report on an original case of a 64 year old lady diagnosed with an extraadrenal mesenteric paraganglioma associated with an incidental histological finding of a gallbladder paraganglion. Paragangliomas are rare neuroendocrine, neural crest-derived tumours, found in diverse locations and display variable catecholamine secreting behaviour. Malignant potential can be difficult to predict on his...

Laryngeal Paraganglioma: A Diagnostic Challenge

Paragangliomas are neoplasms of neural crest origin. In the head and neck, they uncommonly involve the larynx. The distinction between paragangliomas and other neuroendocrine tumors can be difficult. Precise diagnosis is important in order to optimize patient treatment. Diagnosis relies mostly on histopathologic examination followed by immunohistochemistry. Here we report a 77-year-old woman wi...

Tracheal paraganglioma.

The trachea is an unusual site for paragangliomas, only four cases having been documented previously. A fifth case is presented here, together with immunohistochemical evidence that the tumour is biologically benign.
