“…Osteolipoma more commonly occurs in older individuals with a long history of persistence and slow progression [3]. It is a rare tumor that has been reported in various anatomical locations, being even more rare within the oral and pharyngeal region.…”

“…It is a rare tumor that has been reported in various anatomical locations, being even more rare within the oral and pharyngeal region. A total of 19 cases of oropharyngeal osteolipomas have been reported (Table 1) [3][4][5][6][7][8][9][10]. Ten patients, who had intraoral masses in the buccal mucosa, alveolar mucosa, palate, or tongue, were either asymptomatic or presented with facial swelling.…”

Osteolipomas are rare tumors, particularly in the head and neck region, in contrast to lipomas which are the most common benign neoplasms in this location. Osseous changes are benign and mainly occur in longstanding lipomas. Despite its rarity, this neoplasm has a characteristic histopathologic appearance with lamellar bony spicules within the mature adipose tissue. Of the 19 cases previously reported in the oropharyngeal area, only two were located in the submandibular region. We report the third case of submandibular osteolipoma, presenting as an asymptomatic mass in a middle-aged man. Our review of head and neck osteolipomas would be of particular interest to pathologists and head and neck surgeons, in order to avoid inappropriate treatment of an otherwise benign lesion.

“…A review of the English literature found that, outside the head and neck area, lipomas with osseous differentiation have been reported in deep locations adjacent to bone tissue in the thigh [10][11][12][13], knee [14,15], sternoclavicular region [16], shoulder [17], wrist [14], hand [18], intraspinal [19] or in superficial subcutaneous tissue [20,21]. More than 60 % of the cases occur in the head and neck region, where they have been described in intraspinal [22], intracranial [23] (suprasellar/hypothalamic and interhemispheric) and extracranial-extraspinal locations [3][4][5][6][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42]. The latter are summarized in Table 1.…”

Osteochondrolipoma of the Submandibular Region: A Case Report and Review of the Literature

Lipoma is an extremely common and ubiquitous benign soft tissue tumor composed of mature adipose tissue, with frequent differentiation towards other mesenchymal elements such as blood vessels, fibrous tissue, or muscle. They are typically slow-growing, encapsulated, superficial or deep, and have a wide range in size depending on their location. The presence of cartilage or bone is very rare, with most reported cases in the head and neck area. We report the case of an osteochondrolipoma of the submandibular region with associated benign bone marrow elements, with a review of the literature and discussion of the differential diagnosis.

“…Allen et al reported that only 6 of 635 cases with benign lipomas in their study showed ossification (2). Clinically, an osteolipoma, containing mature lamellar bones irregularly arranged in a significant fat component, is quite rare (3,4). In contrast, an ossifying lipoma usually occurs within the intrathecal bone and rarely within the cortical bone.…”
