BACKGROUND Medullary nephrocalcinosis and distal renal tubular acidosis are closely associated and each can lead to the other. These clinical entities are rare in patients with nephrotic syndrome and polycythaemia is an unusual finding in such patients. We describe the presence of medullary nephrocalcinosis, distal renal tubular acidosis and polycythaemia in a patient with nephrotic syndrome du...

RATIONALE Patients with Klippel-Feil syndrome (KFS) are always anomaly associated with vertebrobasilar dysplasia. That may present commonly as infarction of brainstem, medulla, and cerebellum. In this article, we reported a rare case of lateral medullary infarction (LMI) with similar features of Brown Sequard syndrome caused by vertebrobasilar dysplasia and KFS, and the 2 rare conditions that a...

Medullary thyroid carcinoma (MTC) has been described as a source of ectopic ACTH secretion in patients with Cushing's syndrome. This is an infrequent association, occurring in less than 1% of MTC cases. Among these, it is even more unusual for an initial diagnosis of hypercortisolism to lead to the discovery of underlying MTC. Here we present a case of a patient with weakness, diarrhea, and hyp...

Hereditary medullary thyroid carcinoma (MTC) presents within the context of 3 genetic syndromes. Multiple endocrine neoplasia type 2A (MEN2A, Sipple’s syndrome) is an autosomal-dominant genetic syndrome that includes MTC, pheochromocytoma, and primary hyperparathyroidism (PHPT). MEN2B is an autosomal-dominant genetic syndrome that includes MTC, pheochromocytoma, multiple mucosal neuromas, and a...
