Giant Lipoma of the Upper Extremity: Report of 2 Cases and Literature Review

Lipomas are common, benign slow-growing tumours of fat cells (adipocytes). They can occur anywhere in the body, but they are mostly found on the neck, shoulders and trunk. Lipomas are generally small about 3 cm in diameter. However, when a lipoma grows to a size larger than 10 cm it is referred to as a giant lipoma and they make up only 1% of all lipomas. Though usually they are benign in nature, it is essential to rule out the possibility of malignancy due to their large size before undergoing their complete resection. Here we present the cases of a 56-year-old woman with a giant lipoma on her left arm and a 58-year-old man with a giant lipoma on his right shoulder.
