Osteolipoma of the Oral Cavity: A Case Report

Abstract

A literature review of the osteolipoma of the oral cavity and pharyngeal region is also presented. In this localization study, 14 well-documented cases could be found in English-language literature, in which the mean age of patients was 50.6 years, and slight predilection for male gender could be identified. The majority of cases appeared in the oral cavity (67 %). The data demonstrated that osteolipoma of the oral cavity and pharyngeal region is an asymptomatic (80 %) lesion without bone attachment (80 %). The size of the lesions ranged from 8 to 90 mm in diameter (mean = 36 mm), with an evolution time ranging from 1 to 35 years (mean = 7.7 years). Similar to the present case, no recurrence could be identified in works which reported on the follow-up period.

Osteolipoma in the retromolar trigone: A case report and review of literature

“…These calcifications and ossifications are the secondary features of osteolipoma as well as several benign and malignant tumors. Ultrasonography reveals it as hyperechoic mass with areas of focal calcifications[12] which was also revealed by our case also.…”

“…[12] However, in our case, the trabeculae were distributed equally in a uniform manner throughout the tumor-like “concentric layers.”…”

Osteolipoma: a painless mandibular mass

“…Osteolipoma is a rare benign tumor in the oral, facial, and neck regions. Eight cases of mandibular osteolipoma have been reported to date (Table 1) [5,7,[9][10][11][12][13][14]. We are reporting the first case in the submental region.…”

“…Osteolipoma is a rare histopathologic variant of lipoma accounting for less than 1% of all lipomatous cases [4,5]. This lesion was described in many anatomic sites, including the scapula, vertebral spine, neck, skull, suprasellar region, tuber cinereum, oral cavity, and pharyngeal region [2,4,[6][7][8]. Only eight cases of this rare type of lipoma were reported in the mandibular buccal vestibule/alveolar mucosa (Table 1) [5,7,[9][10][11][12][13][14].…”

Osteolipoma of knee: a rare case report

“…An osteolipoma is defined as a lesion with mature adipose tissue and randomly distributed trabeculae of laminated bone [5]. They have been found at various sites, with the highest frequency in the head and neck regions [6,7,8]. Osteolipoma is very rare in distal femur and knee region and only 6 other such cases were reported previously.…”
