Hibernoma
Hibernoma
Hibernoma (/haɪˈbɜːrnəʊmə/) is a rare, benign tumor that arises from brown fat tissue. The term "Hibernoma" is derived from the Latin word "hibernus," which means "pertaining to winter," as brown fat is more active during colder months in animals that hibernate.
Etymology
The term "Hibernoma" was first used in 1914 by Gery, derived from the Latin word "hibernus" (pertaining to winter) and the Greek suffix "-oma" (tumor). This is due to the tumor's resemblance to the brown fat found in hibernating animals.
Description
Hibernomas are typically slow-growing and painless, often discovered incidentally during imaging studies for unrelated conditions. They can occur anywhere in the body where brown fat is found, but are most commonly found in the thigh, shoulder, back, chest, and neck.
Diagnosis
Diagnosis of a hibernoma is typically confirmed through a combination of imaging studies, such as MRI or CT scan, and histopathological examination of a biopsy specimen. The tumor cells resemble brown fat cells, with a high number of mitochondria and small lipid droplets.
Treatment
The standard treatment for hibernoma is surgical removal. Due to its benign nature, hibernomas do not typically recur after complete excision. However, regular follow-up is recommended to monitor for potential recurrence.
