“…ey are encountered in 1% of primary hyperparathyroidism cases [12]. eir radiological aspects include lytic lesions, with well-limited contours, without sclerosis, being either eccentric or cortical, with thinning, blowing, or rupture of the cortex [13]. In most cases, the brown tumors secondary to primary hyperparathyroidism are unique and are most often located in the facial bones, more rarely in the long bones, pelvis, spine, and base of the skull [14].…”

Adrenal adenolipomas are rare lipomatous adrenal tumors that can be either functional or not. Only 7 cases have been reported in the English literature so far. However, brown tumors are benign, rare, historical lesions, with histological similarity to giant tumors that can be encountered in 1% of all primary hyperparathyroidism cases. We report the case of an unusual association of bilateral lipoadenoma of the adrenal glands and humeral brown tumor in a 35-year-old patient. He presented to the emergency department with a pathological fracture of the left humerus secondary to a brown tumor. The medical investigations have concluded to primary hyperparathyroidism. The screening for multiple endocrine neoplasia type 1 revealed the presence of bilateral nonsecreting adrenal masses whose anatomopathological study concluded adenolipomas. Adrenal tumors may constitute a part of multiple endocrine neoplasia type 1 in 20 to 40% of cases. In this view, it is necessary to check for the presence of other endocrine gland tumor locations such as primary hyperparathyroidism, neuroendocrine tumors of the duodenum and pancreas, or pituitary adenomas.

“…Brown tumors are osteolytic giant-cell lesions originating from the increased osteoclasts activity in the setting of chronically elevated parathyroid function as both primary and secondary hyperparathyroidism (HPT) ( Triantafillidou et al, 2006 ). Brown tumors involve more frequently the ribs, clavicle, tibia, femur, pelvic girdle and hands ( Elqatni et al, 2011 ), while rarely the maxillo-facial bones (4.5% of cases) ( Slama et al, 2007 ; Lessa et al, 2005 ; Keyser and Postma, 1996 ). It is not easy to distinguish them from osteolytic metastases or lesions from multiple myeloma, with which they share similar characteristics ( Kalathas et al, 2010 ).…”
