title: Case report of parathyroid carcinoma with raised urinary catecholamines: a diagnostic dilemma.
abstract: Parathyroid carcinoma is often misdiagnosed as thyroid carcinoma clinically and also with fine needle aspiration cytology. Moreover in cases misdiagnosed as thyroid carcinoma pre operatively, raised urinary catecholamines may mislead to a diagnosis of MEN2 A. We report a case of a patient admitted to the surgery department ofour hospital with a swelling in the thyroid region, raised urinary catecholamines and urinary VMA levels, with hypercalciuria and elevated parathyroid hormone levels. It was clinically suspected as thyroid carcinoma with parathyroid adenoma and associated MEN 2A syndrome.
