We present a case of primary hyperparathyroidism (PHPT) and osteitis fibrosa cystica with involvement of multiple facial bones and neurocranium. Although the initial differential diagnosis was between acromegaly and bone malignancy, endocrine assessment demonstrated PHPT, with favorable outcome after parathyroidectomy.Case report: A 59-year-old woman referred to our clinic with painful swelling...

Multiple endocrine neoplasya type 2 (MEN-2) is a rare hereditary complex disorder caused by a germline activating mutation of the RET proto-oncogene. The estimated prevalence is approximately 1:30.000. Three clinical forms have been described depending on the phenotype: MEN2A (80%), MEN2B and familial medullary thyroid carcinoma (MTC).Clinically, MEN2A present with MTC (80–100%), unilateral or bilateral pheocromocytoma (40%) and primary hyperparath...

Medullary thyroid carcinoma (MTC) is a rare malignancy arising from parafollicular C cells of the thyroid gland, sometimes due to germline mutations in the RET protooncogene. Testicular cancer is the most common malignancy in men aged 15 - 40 years with survival rates improved by the introduction of cisplatin therapy in the late 1970s. Nonetheless, platinum-based chemotherapy was shown to increase the risk of a solid second cancer with substantially increased site-specific ris...
