A comparative immunohistochemical study of phaeochromocytomas and paragangliomas.
There is no definite morphological distinction between phaeochromocytomas and paragangliomas. We, therefore, attempted to determine the universality and differential utility of a panel of tumour markers for diagnosis in formalin-fixed, paraffin-embedded specimens. Antibodies to neuron-specific enolase (NSE), chromogranin, synaptophysin, Leu-7, neurofilaments, cytokeratins, carcinoembryonic anti...
متن کاملMR imaging features of benign retroperitoneal paragangliomas and schwannomas
BACKGROUND To determine whether MRI feature analysis can differentiate benign retroperitoneal extra-adrenal paragangliomas and schwannomas. METHODS The MRI features of 50 patients with confirmed benign retroperitoneal extra-adrenal paragangliomas and schwannomas were retrospectively reviewed by two radiologists blinded to the histopathologic diagnosis. These features were compared between two...
متن کاملCalcifying Odontogenic Cyst with Complex Odontoma: Histological and Immunohistochemical Features
The calcifying odontogenic cyst (COC) is a rare odontogenic cyst. Only 2% of all odontogenic cysts and tumors are COC. COC associated with odontoma (COCaO) reported in 24% of COCs. COCaO presents a greater incidence in female, with a ratio of 2 to 1. The highest incidence of COCaO occurs during the second decade with a mean age of 16 years, most frequently occurring in the maxilla (61.5%). Here...
متن کاملDopamine-secreting phaeochromocytomas and paragangliomas: clinical features and management.
Most functional phaeochromocytomas/paragangliomas produce noradrenaline and/or adrenaline. Those that produce dopamine are rare. We describe the distinguishing clinical features of dopamine-secreting phaeochromocytomas and paragangliomas from those that secrete noradrenaline/adrenaline and the impact on their management. We present a case of a dopamine-secreting paraganglioma from our instituti...
متن کاملIntrathoracic Malignant Peripheral Nerve Sheath Tumor: Histopathological and Immunohistochemical Features
Malignant peripheral nerve sheath tumor (MPNST) is a rare nerve sheath tumor derived from Schwann cells or pleuripotent cells of neural crest. Neurogenic tumors make about 10-20% of all mediastinal tumors. Incidence of MPNST is 0.001% in general population and 0.16% in patients with neurofibromatosis I (NF I). We report a case of 60 year female presenting with progressive cough and breathlessne...
