Corpus callosum lipoma is a rare congenital brain condition that may or may not present with symptoms. [11] This occurs in the corpus callosum, also known as the calossal commissure, which is a wide, flat bundle of neural fibers beneath the cortex in the human brain. Hibernomas are lipomas of brown fat.
Spindle cell lipoma is most frequently located in the upper back, shoulder, or posterior neck subcutaneous layer. [3] Nonetheless, reports of it occurring in the mediastinum, hypopharynx, larynx, anterior neck, suprasellar region, esophagus, nasal vestibule, tongue, floor of mouth, vallecula, parotid gland, and breast have been made.

[25] Although lipomas can develop at any age, they more commonly appear between the ages of 40 and 60. [24] Lipomas affect about 1% of the population, with no documented sex bias, and about 1 in every 1000 people will have a lipoma within their lifetime. [25] [26] The cause of lipomas is not well defined.

In 1993, a genetic polymorphism within lipomas was localized to chromosome 12q15, where the HMGIC gene encodes the high-mobility-group protein isoform I-C. [2] This is one of the most commonly found mutations in solitary lipomatous tumors but lipomas often have multiple mutations. Reciprocal translocations involving chromosomes 12q13 and 12q14 ...
Most cases of pleomorphic lipoma are seen in the subcutaneous tissue of the back, shoulder, and posterior neck. [2] Less commonly, it can also happen in odd places like the tongue, [3] vulva, [4] palm, [5] tonsillar fossa, [6] orbit, [7] and oral cavity. [8] The lesion usually presents as a subcutaneous lump that is circumscribed, like the ...
HPV, the human papilloma virus, caused the cancer on base of Moog’s tongue. A lump in the neck due to a swollen lymph node that slowly gets bigger is a common symptom of cancers in the mouth ...
[10] [17] The fat deposited around the front of the neck is known as Madelung's collar or horse collar. [13] [5] Fat deposited on the back of the neck between the shoulder blades is known as a dorsocervical fat pad or buffalo hump. [13] [18] Fat deposited in the parotid region is known as hamster cheeks. [10]
