Abstract

Parathyroid lipohyperplasia is an extremely rare cause of hyperparathyroidism. According to a MEDLINE search, there have been only 9 previously reported cases of parathyroid lipohyperplasia in the English-language literature. We report a new case of parathyroid lipohyperplasia, with a brief discussion of this rare disease process.

IntroductionParathyroid hyperplasia is a cause of hyperparathyroidism defined as a proliferation of parenchymal cells leading to an increase in gland weight.1This increase in weight is a result (at least in part) of the glands’ high adipose tissue content. The two most common types of parathyroid hyperplasia are chief cell hyperplasia and water-clear cell hyperplasia. Only 9 cases of parathyroid lipohyperplasia previously have been reported in the English literature.2-4 Case report
