Abstract
Lipoma is the most common type of benign soft tissue tumor and is composed of mature adipose tissue. A neoplasm of adipose tissue with admixed mature bone and cartilage, or osteochondrolipoma, is an extremely rare histologic variant. Most documented osteochondrolipomas have occurred in the soft tissues of the head and neck related to the oral cavity, and the tumor is seen involving the extremities. A fatty mass with nonlipomatous elements can present a diagnostic challenge. We present a rare case of osteochondrolipoma involving the wrist. The clinical presentation, radiographic images, histologic findings, and treatment are discussed in this case report.

Abstract
Background Parosteal lipoma is a rare and benign neoplasm originating from mature adipose tissue near the periosteum. Clinically, it is difficult to diagnose due to its similarity to the clinical manifestation of sarcoma, so imaging, histopathology, and immunohistochemistry examinations are necessary. Case presentation A 54-year-old woman presented with lump on the right thigh that had gone through surgery eight years prior, with a diameter of 20 cm, with a partly hard and partly soft consistency, the patient was diagnosed with suspected recurrent liposarcoma. We performed wide excision and histopathological results showed a proliferation of bone cells and cartilage cells that were lobulated, surrounded by a proliferation of fat cells with no pleomorphism or immature cells. Discussion Parosteal lipomas are neoplasms derived from adult adipose tissue, usually connected to the periosteum, and rare and benign. Two theories of pathogenesis of parosteal lipomas. (1) tumors arise from the differentiation of stem cells derived from adipose tissue, (2) the tumor is derived from secondary metaplasia of fibroblasts due to recurrent trauma, metabolic changes, or ischemia. Based on the theory, it is likely that in this case is due to the presence of differentiation of adiposa tissue due to the non-acquisition of a history of trauma. Conclusion Parosteal lipoma is a rare case of benign neoplasm, which is difficult to diagnose clinically due to its similar sarcoma, thus requiring imaging and histopathological examination. The treatment of choice is wide excision by taking the entire tumor to prevent a recurrence. 45 year old woman with recurrent parosteal lipoma. The case of parosteal lipoma is a benign tumor. A neoplasm originating from mature adipose tissue, mostly located in the bone cortex below the periosteum. The incidence is 0.3% of all types of lipomas and 0.1% of primary bone neoplasms.

Abstract
OBJECTIVES Lipomas are the most common benign mesenchymal tumors of soft tissue. According to previous studies, 1-4% of the cases has been observed in the oral cavity. A histological variant of lipoma featuring bone formation is called osteolipoma and has been very rarely observed (less than 1% of the total). In order to make a meaningful addition to this rare knowledge base, our study aims to provide a literature review and to report an additional case of osteolipoma. METHODS An electronic search in the PubMed database with the keyword "osteolipoma" was conducted. Among 69 search results, only the cases of osteolipoma located in the "oral cavity" were included in this study. The findings of the previously reported 20 cases (in English) of osteolipoma of the oral cavity were organized in a table along with a new case of osteolipoma located in the mandibular buccal vestibule with radiological and histopathological findings provided by the authors. RESULTS Osteolipoma affects both sexes and usually emerges in middle-aged or elderly patients with a long history of slow progression. Different imaging techniques may be utilized in the radiographic evaluation. CONCLUSION Differential diagnosis includes a wide range of lesions; therefore, the clinical and radiographic evaluation should be confirmed by histopathological examination. The suggested treatment is complete surgical excision and follow-up, and the prognosis is generally good.

Abstract
Background: Lipomas are the most common benign soft tissue tumors in the general population. These lesions can appear on any part of the body and usually develop in the subcutaneous superficial tissue. Lipomas that show ossifying changes are very rare, representing less than 1% of the reported lipomas. They usually manifest as hard nodular lesions in the head and neck, the extremities, the sternoclavicular region, and the subcutaneous tissue in general; they are rare in the costal arches. Case presentation: We report the case of a patient with a history of multiple diseases and 2 tumor-like lesions with internal lytic areas detected in the fourth right costal arch and in the eighth left costal arc; we describe his clinical manifestations, radiological and laboratory findings as well as the pathological results and outcome. Conclusions: Ossifying lipomas are rare benign tumors with asymptomatic clinical presentation. It is important to perform an adequate radiological differentiation from other more aggressive lesions such as liposarcomas.

Abstract
Lipoma and its variants rarely involve the oral cavity. Osteolipoma of the hard palate is extremely uncommon with only a few cases reported worldwide. It is important to recognize and give comprehensive diagnosis of this entity, so as to prevent unwarranted medical interventions. Here, in this report, we describe a rare case of osteolipoma arising in the hard palate of a 35-year-old male and the diagnostic conundrum associated with it. The approach to such a case, differential diagnosis, and review of the literature are also presented.

Abstract
Objective: Lipomas are very common benign tumors located in any part of the body in which fat is normally present, but lipomas containing both osseous and cartilaginous elements are rare. Methods: A case of osteochondrolipoma in a 72-year-old man is reported. The tumor in the mental region was 2×1.5×1.5 cm. Results: After resection of the tumor, there has been no recurrence during the 6-month postoperative follow-up. Histological examination confirmed the definitive diagnosis. Conclusions: Osteochondrolipoma is an extremely unusual lesion that should be kept in mind in the differential diagnosis of soft-tissue tumors.

Abstract
Lipomas are benign mesenchymal neoplasms of soft tissue that can be found commonly in any part of the human body. Their presence in the oral mucosa is uncommon, however, with approximately 4% of the cases occurring in the oral cavity. Oral lipomas are likely to have originated from mature adipose tissue and there are several histological variants of lipomas described, which are identified according to the predominant type of tissue in addition to adipose tissue. A rare lipoma variant, known as an osteolipoma or an ossifying lipoma, may occur; however, little has been written this type of lipoma characterized by a classical lipoma with areas of osseous metaplasia. This paper describes a case of an osteolipoma involving the buccal mucosa of an adult patient.

Abstract
Lipomas are the most common soft tissue tumors in adults. They often carry chromosome aberrations involving 12q13~15 leading to rearrangements of the HMGA2 gene in 12q14.3, with breakpoints occurring within or outside of the gene. Here, we present eleven lipomas and one osteochondrolipoma with a novel recurrent chromosome aberration, t(12;18) (q14~15;q12~21). Molecular studies on eight of the tumors showed that full-length HMGA2 transcript was expressed in three and a chimeric HMGA2 transcript in five of them. In three lipomas and in the osteochondrolipoma, exons 1–3 of HMGA2 were fused to a sequence of SETBP1 on 18q12.3 or an intragenic sequence from 18q12.3 circa 10 kbp distal to SETBP1. In another lipoma, exons 1–4 of HMGA2 were fused to an intronic sequence of GRIP1 which maps to chromosome band 12q14.3, distal to HMGA2. The ensuing HMGA2 fusion transcripts code for putative proteins which contain amino acid residues of HMGA2 corresponding to exons 1–3 (or exons 1–4 in one case) followed by amino acid residues corresponding to the fused sequences. Thus, the pattern is similar to the rearrangements of HMGA2 found in other lipomas, i.e., disruption of the HMGA2 locus leaves intact exons 1–3 which encode the AT-hooks domains and separates them from the 3′-terminal part of the gene. The fact that the examined osteochondrolipoma had a t(12;18) and a HMGA2-SETBP1 fusion identical to the findings in the much more common ordinary lipomas, underscores the close developmental relationship between the two tumor types.
