Thigh Mass in a Toddler: Case Study of a Giant Fibrolipoma

Lipomas are the most common mesenchymal tumors in humans, with a slight male preponderance. Most lipomas affect the trunk and upper extremities; however, they can occur anywhere on the body where adipocytes exist. These are usually small, measuring less than one inch to a few inches in diameter. When a lipoma grows to a size of more than 10 cm (about 4 inches) or by a minimum of 1000 g, it is called a giant lipoma. Only about 1% of all lipomas can be classified as "giant." Lipomas are made up of lobulated, slow-growing, mature adipocytic tissue with limited connective tissue stroma. Differentiating between lipoma and liposarcoma of low-grade malignancy is typically difficult and involves several radiological examinations and histopathology. We are reporting a rare case of giant fibrolipoma in the right thigh of a two-year-old male child.
