Abstract
Lipomas are considered one of the most frequent benign mesenchymal tumors with copious variants. Among these variants is angiomyxolipoma (AML) which is considered an extremely rare entity. To the best of our knowledge, only 19 cases have been reported in the English medical literature, of which three of them involving the spermatic cord. Herein, we report the fourth case of a 37-year-old male patient with angiomyxolipoma (AML) of the spermatic cord discovered incidentally during elective hernia repair.

Wong BLK, Hogan C. Osteolipoma of head and neck - a review. Braz J Otorhinolaryngol 2022; 88 Suppl 4:S177-S187. [PMID: 35659712 DOI: 10.1016/j.bjorl.2022.04.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2022] [Revised: 03/17/2022] [Accepted: 04/25/2022] [Indexed: 12/14/2022] Open
Abstract
OBJECTIVE Due to the rarity of osteolipoma, current knowledge and understanding of its' clinical presentation, management, radiological features, histological characteristics, and prognosis are lacking and can present a clinical conundrum to clinicians and histopathologist alike, given wide range of differential diagnoses. This paper aims to compile, analyse and present details to augment the available literature on osteolipoma in the head and neck. METHODS A comprehensive literature search on PUBMED/MEDLINE, EMBASE, CINAHL and Science Citation Index, Google scholar and Cochrane database for osteolipoma in head and neck was performed up to the 1st May 2021. Reference lists from the relevant articles were then inspected and cross-referenced and any other pertinent publications were added to the review. RESULTS A total of 38 cases were identified from the literature. The commonest sites of involvement within the head and neck region were the oral cavity in 21 (56.8%) patients, followed by the neck in 7 (19.0%) patients. 29 (78.4%) patients presented with soft tissue swelling or mass making it the most common presenting feature. All patients had the tumour excised surgically; of which 18 (48.6%) were excised via transoral approach and 6 (16.2%) via open transcervical approach including 1 lateral pharyngotomy. 12 papers documented long-term follow-ups (median 12 months) with no recurrence. Only 1 regrowth was reported after 5-years. CONCLUSIONS Osteolipoma is a rare soft tissue neoplasm which has a wide range differential diagnosis including malignant processes. Recognising this benign tumour through an awareness of presenting sign and symptoms, radiological features and histopathology findings is important for patient reassurance as well as avoiding unnecessary radical treatment.

Abstract
Introduction: Lipomata are soft-tissue mesenchymal neoplasms that are benign in nature and often asymptomatic. Lipomata commonly occur in the body, however, only 1%–5% are identified within the oral cavity, and lipomata with osseous metaplasia account for <1% of all lipomata. Materials and Methods: A PubMed literature review designating search terms including “oral” and “parosteal lipoma” or “lipoma with osseous metaplasia” or “ossifying lipoma” or “osseous lipoma” was conducted. Results: The literature review identified two previous reports of parosteal localization of lipomata in the mandible and 22 cases of lipomata with osseous metaplasia within the oral cavity. Conclusions: With the initial suspicion of a more malevolent diagnosis, this rare entity, with only two other cases identified, is important to consider in the clinician's differential diagnoses.

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
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
Spindle cell lipoma (SCL), also called as pleomorphic adenoma, is a rare variant of lipoma histopathologically characterized by an admixture of mature fat cells with spindle cells and occasionally mast cells with myxoid connective tissue stroma and thick bends of birefringent collagen. Although buccal mucosa is the most common location for oral lipomas, for SCL, it is an exceedingly rare location. We report a case of an asymptomatic swelling of buccal mucosa that simulated the features of neurofibroma on histopathological examination, and the final diagnosis of SCL was made on the basis of immunohistochemical features. This is the first documentation of oral SCL using SOX10 to achieve the final diagnosis.

Abstract
The paper describes a case of parosteal lipoma of the temporal bone, by simultaneously involving the parotid salivary gland. Computed tomography performed in a 48-year-old man showed that in the area of the posterior edge of the glenoid fossa of the right temporal bone there was a massive (1.5×1.7×0.9-cm) exostosis extending down from the skull base. The exostosis was surrounded by a 3.5×3.6×5.3 soft tissue mass that was located in the projection of the right parotid salivary gland with a capsule and minor calcifications. Morphological examination determined a sessile exostosis-like mass in the area of the periosteum of the temporal bone. Foci of desmal and enchondral ossification (types III and IV according to the classification of Miller et al.) could be seen in the adjacent fatty tissue. The tumor underwent necrotic and dystrophic changes (Milgram's Stage 3). Temporal bone involvement was accompanied by osseous sialolipoma of the right parotid salivary gland. In this case, the fatty component accounted for 60-80% of salivary gland volume. Terminal secretory segments, ducts, and bone trabeculae with calcification foci and hematopoietic elements were uniformly distributed among the fatty tissue. None similar case has been found in the literature.

Abstract
Osteolipoma is a rarely reported histologic variant of lipoma that exhibits bone formation. To the best of our knowledge, only 13 well-documented case reports of osteolipoma in the oral cavity have been published in the English literature. This study presents the clinical, radiographic, and histologic features of an osteolipoma in the oral cavity and reviews the pertinent literature. The patient was a 29-year-old female, who presented with an 8-month history of a painless, progressively enlarging, well-defined, movable submucosal mass in the left posterior buccal mucosa. The lesion had a hard consistency. Imaging findings revealed a spherical radiopacity with an irregular trabecular pattern. The lesion was excised and the diagnosis of osteolipoma was established. No recurrence was observed after a 5-year follow-up.
