Intramuscular hemangioma of the forearm; Report of a case

ABSTRACT

A case of intramuscular hemangioma of the right forearm and hand muscle is presented in this study. This tumor may infiltrate the muscle and be misdiagnosed as a malignant neoplasm. The patient, a 14-year-old girl, presented to the clinic with right forearm and hand pain and swelling which began when she was 2 years old and had been gradually increasing in size. Because the mass might have been malignant, in 1990 a biopsy was performed. Histologic analysis revealed a benign intramuscular hemangioma. A second biopsy at 1992 reported intramuscular hemangioma, mixed type again. She had not received any other treatment. She was seen in March 2003 when the size of the mass had increased and was associated with a dull ache and swelling limited hand movements. The patient subsequently received radiotherapy
