Non Infiltrating Angiolipoma of the Palate in Geriatric Patient: A Case Report with Review of Literature

Abstract

Angiolipoma is one of the rare variant of lipoma. This benign tumour consists of both fatty and vascular elements. It mostly occur in the trunk and extremities and is uncommon in head and neck region. Angiolipoma is classified as infiltrating and non- infiltrating types. Among all neoplasms of the oral cavity, lipomas account for 1 to 5% and the incidence of angiolipoma is 5 to 17% in it. There is no sex predilection for this tumour. It is classified as infiltrative and non-infiltrative type. Surgical excision is the method to be considered for both the types of angiolipoma, however the infiltrating type recurs post-surgery. We report a rare case report of 55-year-old female with non-infiltrating angiolipoma of the hard palate mimicking a mucocele treated by surgical excision with no signs of recurrence and good wound healing after three months follow up with minimal scar formation.

Periauricular Angiolipoma: A Case Report

“…Angiolipoma is a variant of lipoma that includes mature lipocyts and blood vessels (2)(3)(4)(5)(6). In different cases, the ratio of the lipocyt to the blood vessels varies, but in most of them the percentage of lipocyts is higher than blood vessels (4,8).…”

“…Location of the tumor is a major factor in determining its prognosis (7). Angiolipomas usually happen sporadically, but a few cases have a family history of angiolipoma, and the inheritance pattern in these cases is autosomal recessive or in very rare cases autosomal-dominant pattern (5,10). Also, in a study that examined the karyotype of three cases of angiolipoma, the researchers concluded that all three cases had abnormal karyotypes with loss or structural rearrangement of chromosome 13 (8).…”

“…Also, in a study that examined the karyotype of three cases of angiolipoma, the researchers concluded that all three cases had abnormal karyotypes with loss or structural rearrangement of chromosome 13 (8). Histopathologic studies are required for definitive diagnosis of angiolipoma from other soft tissue tumors such as hemangioma, myxolipoma, and Kaposi's sarcoma; magnetic resonance imaging (MRI) can be useful in evaluation of the tumor expansion and preoperative diagnosis (5,11). Surgical excision is the best treatment for both encapsulated and un-capsulated angiolipomas (2,3,7).…”

“…Lipomas are fatty tumors and 5-17% of these tumors are angiolipomas (1). Angiolipoma is a variant of lipoma that includes mature lipocyts and blood vessels (2)(3)(4)(5)(6). Infiltrating angiolipoma are often placed deeper than the non-infiltrating form (1,7).…”

Oral lipoma located at the left lower vestibule-report of a case and a brief review of the literature

“…Histologically, oral lipomas are divided into subtypes based on the matrix and the properties of tumor cells: simple lipoma, fibrolipoma 4,12,13 , spindle cell lipoma 5,14 , intramuscular lipoma 14 , chondrolipoma, pleiomorphic lipoma, myxoid lipoma or myxolipoma 15 , angiolipoma 16,17 , osteolipoma 18,19 , angiomyxolipoma, sialolipoma, infiltrating lipoma, perineural lipoma, intraneural lipoma and atypical lipoma 1,2,8 . Despite the fact that the etiology and pathogenesis of the tumor are not clear, two main theories have been claimed: (i) The Hypertrophy theory, which correlates obesity and inadvertent growth of adipose tissue with the formation of oral lipoma 1 .…”
