Lipomas are benign soft tissue tumors that can be either superficial or deep. Superficial lipomas are mostly asymptomatic whereas deep-seated lipomas can occasionally cause symptoms if they grow adjacent to neurovascular structures. In this report, we present a case of parosteal lipoma of the right proximal forearm in a 47-year-old male, which was initially diagnosed as intramuscular lipoma stretching posterior interosseous nerve (PIN), with no neurological complaints during both preoperative and postoperative periods.

Parosteal lipoma is a rare tumor that occurs very close to the bone, and accounts for approximately 0.3% of all lipomas. Chondrolipoma, a lipoma with cartilaginous metaplasia, is also a rare tumor consisting of mature adipose and cartilage tissues.

Deep-seated lipomas can be intramuscular, intermuscular, and rarely, parosteal lipomas. Intramuscular lipoma can be divided into infiltrative, well-circumscribed, and mixed types. Marginal excision is the treatment of choice for well-circumscribed intramuscular lipoma, and histopathology eliminates diagnosis of well-differentiated liposarcoma.

Parosteal lipomas and osteochondromas of the head and neck are uncommon benign tumors, constituting a small fraction of lipoma and bone tumor cases. We present a unique case of a 66-year-old male with a parosteal lipoma overlying an osteochondroma in the anterior midline neck, causing dysphagia. Surgical excision confirmed the diagnosis, and a literature review revealed similar cases predominantly adjacent to the mandible or calvaria.
