A case report on Intramuscular Myxoma

Abstract

Intramuscular myxoma is a rare mesenchymal tumour reported to be in 1 in one lakh population and most frequently diagnosed in females (~57%) patients between fifth and sixth decades of life. These tumours are commonly benign in nature and it usually favours in thighs, shoulders, buttocks. A very rare site of this tumour is forearm mainly found in elderly patients. Generally, myxoma is composed of gelatinous material that has a myxoid histologic appearance. They are slow growing, asymptomatic and submucosal masses. There is no known underlying cause for this condition but it is suspected that it can occur due to the combination of genetic and environmental risk factors. In this case report local reoccurrence has not been reported after resection. We treated the patient with surgical excision and that seems to be the most effective treatment. After surgical excision if reoccurrence occurs histopathologic diagnosis should be reviewed. The tumor may be low grade myxoid neoplasm and treatment plan may be changed. An elderly patient presenting with a solitary soft tissue tumour should be thoroughly investigated to rule out the soft tissue sarcomatous conditions, which in many ways mimic the intramuscular myxoma.
