Parathyroid lipoadenoma: The particularities of a rare entity a case report and review of the literature.

Parathyroid lipoadenoma is a rare and anusual cause of primary hyperparathyroidism. The clinical presentation usually resembles other causes of primary hyperparathyroidism and the imaging is not always contributory considering its location. However, the histologic criteria are specific. We present a case that supplements and supports the rare literature data concerning the clinical and therapeutic aspects of parathyroid lipoadenoma. The case is about a 73 years old female with a right inferior parathyroid lipoadenoma that caused biological primary hyperparathyroidism. Initially followed and treated in Rheumatology department for hypercalcemia and osteoporosis, she was sent to our structure to diagnose and possibly treat the causal etiology. After non-contributory clinical examination and ultrasound imaging, the tumor was diagnosed in the cervical CT scan. The patient underwent successful surgical removal of the lipoadenoma, confirmed postoperatively on histological analysis. The follow up showed rapid normalization of the parathormon level. Even if it's a rare condition, the diagnosis of lipoadenoma should always be considered in front of primary hyperparathyroidism with a parathyroid lesion.
