Review
BACKGROUND
Esophageal lipomatous tumors, also reported as fibrovascular polyp, fibrolipoma, angiolipoma, and liposarcoma, account for less than 1% of all benign mesenchymal submucosal tumors of the esophagus. Clinical presentation and therapy may differ based on location, size, and morphology. A comprehensive and updated systematic review of the literature is lacking.
METHODS
A systematic review of the literature was performed according to PRISMA guidelines. Pubmed, Embase, Cochrane, and Medline databases were consulted using MESH keywords. Non-English written articles and abstracts were excluded. Sex, age, symptoms at presentation, diagnosis, tumor location and size, surgical approach and technique of excision, pathology, and morphology were extracted and recorded in an electronic database.
RESULTS
Sixty-seven studies for a total of 239 patients with esophageal lipoma or liposarcoma were included in the qualitative analysis. Among 176 patients with benign lipoma, the median age was 55. The main symptoms were dysphagia (64.2%), transoral polyp regurgitation (32.4%), and globus sensation (22.7%). The majority of lipomas (85.7%) were intraluminal polyps, with a stalk originating from the upper esophagus. Overall, 165 patients underwent excision of the mass through open surgery (65.5%), endoscopy (27.9%), or laparoscopy/thoracoscopy (3.6%). Only 5 (3%) of patients required esophagectomy. Of the 11 untreated patients with an intraluminal polyp, 7 died from asphyxia. Overall, liposarcoma was diagnosed in 63 patients, and 12 (19%) underwent esophagectomy.
CONCLUSION
Esophageal lipomatous tumors are rare but potentially lethal when are intraluminal and originate from the cervical esophagus. Modern radiological imaging has improved diagnostic accuracy. Minimally invasive transoral and laparoscopic/thoracoscopic techniques represent the therapeutic approach of choice.

Fibrolipoma, a subtype of lipoma, is a painless, well-circumscribed, slow-growing, submucosal benign adipocyte tumour. It is uncommon in the oral cavity and oropharyngeal region. It accounts for 1.6% of all facial lipomas. Fibrolipomas mostly affect the buccal mucosa and buccal vestibule and cause functional and cosmetic disabilities. The diagnosis and differentiation of fibrolipoma with clinically similar lesions such as fibroma and pleomorphic adenoma are very essential for a correct treatment plan and complete follow-up. Here, we present fibrolipoma, a very rare subtype of lipoma involving the buccal mucosa of the left premolar region in a 44-year-old male patient.

Fibrolipoma, an infrequent histological subtype of lipoma, is considered a benign mesenchymal neoplasm. Fibrolipoma of the scrotum is an even more rare entity. We report a case of a 55-year-old male complaining for a slow-growing, painless mass in his left hemis-crotum. Imaging with ultrasonography and magnetic resonance imaging was inconclusive regarding the nature of the tumor and the tumor was excised, sparing the testis. The surgical specimen was a well-defined, yellowish white, solid, and firm mass, measuring 19.5×7×5 cm. There was no cytological atypia or mitosis and no lipoblasts recognized. On immunohistochemistry, MDM2 and CDK4 were not expressed. The histopathology report was fibrolipoma of the scrotum. To the best of our knowledge, this is only the fourth case of fibrolipoma originating from the scrotal components, spermatic cord or testis that has been reported in the English literature.

Objective. Balloon enteroscopy (BE) and capsule enteroscopy (CE) are enteroscopy methods that allow examination and treatment of the small bowel. Before the CE and BE era, the small intestine was difficult to access for investigation. Small intestinal tumours are infrequent conditions, but about half of them are malignant. Materials and Methods. A total of 303 BEs were performed in 179 patients. Oral insertion was performed in 240 and anal in 63 BEs. Indications for the procedure in our patients with small bowel tumours were anaemia and/or bleeding, obstruction, suspicion of carcinoid tumour, or suspicion of Peutz-Jeghers syndrome. Results. In 50 of our 179 patients (28%), we diagnosed some small intestinal tumours: hamartomas in Peutz-Jeghers syndrome in 16 patients, adenocarcinoma in 7, lymphoma in 6, carcinoid tumour in 4, melanoma and stromal tumour in 3, adenoma, lipoma, and inflammatory polyps in 2, and granular cell tumour, cavernous lymphangioma, fibrolipoma, Cronkhite-Canada polyps, and metastatic involvement in individual cases. Conclusion. BE facilitates exploration and treatment of the small intestine. The procedure is generally safe and useful. BE and CE are essential modalities for the management of small intestinal diseases.

Review
Lipomas are benign soft tissue tumours composed mainly of mature adipose tissue. Histological variants of lipomas have been named according to the type of tissue present and they include fibrolipoma, angiolipoma, osteolipoma, chondrolipoma and others. Osteolipoma, a classic lipoma with osseous metaplasia, is a very rare histological variant. Owing to the rarity of oral osteolipomas, we report an uncommon case of osteolipoma located on the floor of the mouth of a 20-year-old female patient and include a review of the literature.

Review
Fat-containing tumors of the salivary glands are uncommon. Their wide histological spectrum varies from pure lipomatous neoplasms similar to their cutaneous and soft tissue counterparts to mixed lipoepithelial lesions specific to the salivary glands. With few exceptions, these uncommon lesions affect mainly the elderly, with a mean age at presentation of ≥ 50 years and show a predilection for males. A few cases occur in childhood; some of them represent congenital lesions. In decreasing order of frequency, ordinary (soft-tissue type) lipoma, oncocytic lipoadenoma, non-oncocytic sialolipoma, and pleomorphic adenoma/myoepithelioma with extensive lipometaplasia are the main variants of fat containing tumors encountered in the salivary glands. While pleomorphic adenoma/myoepithelioma with lipometaplasia behave in the same way as their non-fat-containing counterparts, other lipomatous salivary gland tumors listed above are cured with simple excision and do not carry a risk of recurrence. Other lipoma variants (spindle cell lipoma, osteolipoma, fibrolipoma, angiolipoma, pleomorphic lipoma, lipoblastoma and hibernoma) are exceptionally rare in the salivary gland. Atypical lipomatous tumors/liposarcoma have been only rarely reported in the salivary gland and they behave in a similar fashion to their soft-tissue counterparts. Diffuse lipomatosis and lobular fatty atrophy are the two tumor-like lesions that might closely mimic sialolipoma, particularly in limited biopsy material without knowledge of the gross findings. This review summarizes the clinicopathological features of the main types of salivary fat-containing lesions and discusses their differential diagnoses.

Review
BACKGROUND
Lipomas are benign mesenchymal tumors composed of mature adipocytes. They are classified according to their histological pattern and their etiology remains unclear. Objectives: To present two cases and review the literature.
MATERIAL AND METHODS
A search was conducted in the Medline / PubMed and Scielo data bases of the last 10 years (2004-2014) with the keywords " intraoral lipoma OR oral cavity lipoma".
RESULTS
46 articles with 95 cases (56 women and 39 men) were reviewed. The average age was found to be 52.28 years (52.28 ± 18.55); and most of them occurred between the 4th and 6th decade of life. Lipomas occur mostly in the buccal mucosa (n = 36, 37.9%), followed by the tongue (n = 23, 24.2%) and other locations (n = 36, 37.9%). The most common histologic pattern was simple lipomas (n = 40, 42%), followed by fibrolipomas (n = 18, 18.9%) and other types (n = 37, 39.1%). The average tumor size was 19.77 ± 16.26mm.
CONCLUSIONS
Lipomas are a relatively rare finding in the oral cavity. Surgical excision is the treatment of choice and recurrence is not expected. Benign oral tumor, oral lipoma, lipoma, oral cavity.

Review
The authors report a case of a thoracic epidural spinal lipomatosis causing severe neurological deficits along the review of pertinent literature. The patient is a 56-year-old woman who presented with acute onset of severe paraparesis; she was investigated with cervical and thoracic MRI and then surgically managed because of an intraspinal mass compressing the cord. The operation consisted in the excision of the mass confirmed to be a fibrolipoma by pathological analysis. The patient attained complete neurological recovery and at 18 months follow-up she reported a generalised well-being. Thoracic lipomas are rare lesions that presenting mostly with back pain; however, in rare instances they may cause progressive and/or abrupt neurological dysfunction. Appropriate imaging can help in the diagnosis and management of such cases.

Review
Fibrolipoma is a benign tumor which is classified as a histological variant of conventional lipoma. It rarely occurs in oral and maxillofacial region. When present, it occurs as a soft, smooth surfaced nodular mass that can be pedunculated or sessile. Most of the lesions are less than 3 cm in size, although it may vary. Fibrolipomas mostly affect buccal mucosa and buccal vestibule and cause functional and cosmetic disabilities. Herniation of buccal pad of fat caused by trauma may also mimic lipoma. Hence, accurate histopathological examination of lipomas is important for a correct treatment plan. Here, we present 2 cases of oral fibrolipoma that presented on the retromolar triangle area and alveolar ridge in relation to missing maxillary right first molar.
