Review
Lipomas are adipose tumors that are often located in the subcutaneous tissues of the head, neck, shoulders, and back. Lipomas have been identified in all age groups but usually first appear between 40 and 60 years of age. These slow-growing, nearly always benign, tumors usually present as nonpainful, round, mobile masses with a characteristic soft, doughy feel. Rarely, lipomas can be associated with syndromes such as hereditary multiple lipomatosis, adiposis dolorosa, Gardner's syndrome, and Madelung's disease. There are also variants such as angiolipomas, neomorphic lipomas, spindle cell lipomas, and adenolipomas. Most lipomas are best left alone, but rapidly growing or painful lipomas can be treated with a variety of procedures ranging from steroid injections to excision of the tumor. Lipomas must be distinguished from liposarcoma, which can have a similar appearance.

Review
Angiolipoma is a benign tumor composed of adipose tissue and proliferating blood vessels that is commonly found in the subcutaneous tissue of the trunk and extremities. Gastric angiolipoma is a rare entity, and to the best of our knowledge, only 4 cases have been reported in the English-language literature thus far. These tumors may present as gastrointestinal bleeding and anemia or with obstructive symptoms. Accurate preoperative diagnosis is challenging because of nonspecific clinical symptoms and lack of specific findings on imaging studies. The correct diagnosis is usually made by histopathologic examination. The clinical significance lies in being aware of this rare entity in the stomach and distinguishing it from other benign and malignant gastric neoplasms that may be in the differential diagnosis. We herein discuss the clinical presentation, radiologic and histopathologic features, ancillary studies, differential diagnosis, and treatment and prognosis of this rare entity.

We report a case of cutaneous angiomyolipoma (AML) found on the anterior abdominal wall of a 3-year-old female child. Histologic examination showed a well-circumscribed nodule in the dermis composed of an intimate mixture of convoluted thick-walled blood vessels, smooth muscle, and mature fat. This lesion differs from renal AML in terms of a lack of association with tuberous sclerosis, circumscription, absence of epithelioid cells, and male predominance. We concluded that the unique features of this lesion distinguish it from other lesions such as angiomyoma, angiolipoma, myolipoma, haemangioma, and other mixed mesenchymal tumors. This case report suggests that the features considered diagnostic of AML can occur in extrarenal sites and, therefore, this diagnosis cannot be excluded on the basis of site alone.

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.

Angiolipoma is an uncommon benign fatty tumor which is a variant of lipoma. Microscopic studies on angiolipoma show that it includes the mature lipocytes and blood vessels. Infiltrating angiolipoma is an un-capsulated angiolipoma and, due to penetration into the surrounding structures, complete excision of the tumor is difficult. According to previous studies, the relapse rate of the infiltrating angiolipoma after surgical intervention is 35-50%. Infiltrating angiolipoma is rarely seen in the head and neck region and often occurs in the trunk and limbs. In this study, we report a 10-year-old boy with periauricular infiltrating angiolipoma who underwent surgery. After surgery, the patient developed transient left frontal branch palsy, but recovery was excellent and after one year there is no relapse.

INTRODUCTION
Angiolipoma is a rare and benign variant of lipoma that usually occurs as single or multiple entities. The aim of this study is to present a case of multiple angiolipoma located in the hand, back, and abdomen.
CASE REPORT
A 38-year-old male presented with multiple swellings in his body for a 6-year duration. Physical examination revealed 3 painless masses in the hands, back, and abdomen. Laboratory findings were normal and ultrasound (US) examination suggested multiple body lipoma. The patient was managed with total excision and histopathological examination confirmed the diagnosis of benign angiolipoma. No reoccurrence was observed upon follow-up.
DISCUSSION
Angiolipoma mainly composed of a mixture of proliferating blood vessels and mature adipose tissues, with a degree of vascularity much higher than that of a normal lipoma. It has a slow growing nature that it can be presented as single or multiple neoplasia. It is reported to be more common in the young adult population with male predominance.
CONCLUSION
Angiolipoma is a rare variant of lipoma. It rarely occurs in the hands, especially as a painless mass. Histopathology is required for definitive diagnosis.

Angiolipoma, distinguishable from other lipomas by its excessive degree of vascular vessels, are rare in the head and neck and require unique management. A slow growing mass, located underneath the inferior border of the right mandibular angle of a 51-year-old female, was excised under general anesthesia. Unexpected excessive bleeding during the excision was observed and the histological specimen was diagnosed as angiolipoma. As shown in this case report, pre-operative imaging modalities have a crucial influence and are sufficient to diagnose and manage angiolipomas. The "Gold standard" treatment is excision with clear margins and bleeding management should be taken into account according to appropriate differential diagnosis.
