testicular cancer typically spreads to the lymph nodes, but hematogenous dissemination to distant organs can also occur. bone metastasis is uncommon and is thought to be a poor prognostic indicator. jaw metastasis is exceedingly rare but is of great clinical significance, since it may be the first sign of an occult testicular cancer or the first evidence of relapse of a known tumor. herein, we ...

BACKGROUND Hyperparathyroidism-jaw tumor (HPT-JT) syndrome is a rare autosomal dominant multiple tumor syndrome characterized by hyperparathyroidism due to single or multiple-gland parathyroid tumor(s). Since it was first described in 1990, the genetics underlying the syndrome have been elucidated and typical clinical presentations are becoming clarified as literature describing this rare entit...

Introduction: To report two unusual cases of primary hyperparathyroidism (HPT) that initially manifested with a “ jaw tumor” and to discuss the clinical implications of a giant cell granuloma vs an ossifying fibroma of the jaw. Material and methods: The history, physical examination, laboratory values and the imaging and pathologic findings are described in two patients who presented with a “ja...
