Parathyroid hemangioma: a case report in proof of its existence

Hemangiomas are benign vascular tumors that are most commonly found superficially in the head and neck. Cavernous hemangiomas are located in deeper structures and have been reported in a variety of endocrine tumors. However, parathyroid hemangiomas are exceedingly rare, with only three previously reported cases in the literature, all of which were associated with hyperparathyroidism. Here, we present the first case of an intraparenchymal cavernous hemangioma of the parathyroid gland without accompanying hyperparathyroidism in an otherwise unremarkable gland, accompanied by a brief review of the relevant literature.
