GIANT INTRAMUSCULAR LIPOMA OF THE FOREARM – A RARE CASE REPORT

Abstract

The most prevalent soft tissue tumors that originate from adipose tissues are lipomas. They grow slowly, hardly getting larger than 2 cm. Giant lipomas are tumors larger than 5 cm that can develop anywhere in the body, albeit they are rare in the upper limbs. Most lipomas are asymptomatic, but when they enlarge, they can produce symptoms like discomfort, limb pain, and cosmetic deformity because they squeeze the underlying neurovascular structures. Magnetic resonance imaging is necessary for deep-seated lipomas, such as intramuscular or parosteal lipomas, in order to assess the lesion and rule out any malignant characteristics. It is important to consider the possibility of malignant development into liposarcoma in big lipomas. Malignant transformation appears as a solid component, hemorrhage, and infiltration into neurovascular regions on imaging. Following removal, histological analysis confirms these findings. Usually, surgical excision results in full symptom recovery. Here, we report a rare instance of a massive forearm intramuscular lipoma.
