Primary hyperparathyroidism (PHPT) is characterized with primary hyperproduction of parathyroid hormone (PTH) by affected parathyroid glands and with a corresponding increase in concentration of extracellular calcium. Long-term development of PHPT through decades leads to calcium-related symptoms and distinct changes in the skeleton, kidneys, digestive tract and other organs. In the clinical picture of PHPT, granulomatous pseudo-tumors in bones are observed as a rare manifestation of the disease – these lesions, which could imitate malignancy, are called «brown tumors». The present publication that goes into details about a clinical diagnosis, in which a brown tumor became the primary manifestation of PHPT, may be useful for physicians across various fields.
