The paper reports the case of a maxillary brown tumor as early sign of primary hyperparathyroidism. Brown tumors are very unusual growths in daily ENT practice and an odd start of primary hyperparathyroidism. The AA. emphasize the importance of a correct differential diagnosis, especially with those tumors showing multinucleated giant cells (osteoclast type)--such as true giant cells tumor and central giant granuloma--prior to its management. They also comment on the interesting contribution to diagnosis by imagery brought by CT scan, magnetic resonance (MR), ultrasonography (echography) and digital subtraction gammagraphy to attain the topographic site of the parathyroid tumor.

We report a clinical case of a 26 years old female who had a 2 years evolution chin tumour with hypercalcemia (11.8 mg/dl) and PTH (paratohormone) of 761 pg/ml. She underwent a CT scan and MRI of the mandible, as well as a biopsy followed by excision of the tumour by the maxilofacial surgeons. Our ENT Department asked for a Scintigraphy (Tc99s-mibi) and thoracic-cervical CT, which showed a lesion that turned out to be an adenoma of the lower right parathyroid gland after surgery and pathological examination. The patient suffered a Primary hyperparathyroidism that was the main stimulus for the Brown Tumour made up by macrophagos and multinuclear giant cells, being this the first manifestation of the metabolic disorder. This form of hyperparathyroidism is very rare in the clinic. We do a literature review to establish the differential diagnosis for such pathology.

The skeletal lesions of primary hyperparathyroidism, including brown tumour, are rare nowadays, with the practice of checking serum calcium levels leading to an earlier diagnosis of hyperparathyroidism. Clinical, laboratory, radiographic and histological investigations can lead to a correct diagnosis. Treatment of brown tumour focuses on the hyperparathyroidism, and is usually followed by a regression of the brown tumour. The diagnosis of hyperparathyroidism and brown tumour should be considered in patients with hypercalcaemia and an osteolytic expansive bone lesion. We present a patient where a brown tumour of the mandible was the presenting symptom of primary hyperparathyroidism.

Spontaneous retropharyngeal hemorrhage from a cervical parathyroid adenoma is a rare complication of primary hyperparathyroidism. Because of its rarity, it has seldom been documented in the radiologic or ENT literature. Patients may present with a variety of manifestations, ranging from dysphagia to dysphonia to life-threatening dyspnea or hemorrhage. Awareness of a possible thyroid or parathyroid etiology may expedite treatment and prevent unnecessary interventions. We present a case of spontaneous retropharyngeal hemorrhage in which the "sentinel clot" sign enabled us to identify the lesion of origin.
