Intramuscular myxoma of the left forearm

Authors

Abstract

Background: intramuscular myxomas are rare benign mesenchimal tumors of musculoskeletal system. They have a low incidence and affect more frequently women in the fourth to fifth decades of life.
Objective: to present a case of intramuscular myxoma of the left forearm diagnosed and treated at Universitary Hospital Manuel Ascunce Domenech with favorable clinical evolution.
Case report: a 38 year old male patient with past medical antecedents and volume increase in the left anterolateral forearm without no other symptoms. On physical examination a five centimeters soft, mobile, lax and painless tumor was palpated. The soft tissues echography showed an image of low echogenicity with well-defined margins and a thin and integral capsule, rounded by muscles that sized 53 millimeters long per 35 millimeters wide. Surgical treatment was decided to remove the tumor and biopsy that revealed a hypo-cellular and hypo-vascular lesion, compound by fusiform cells without atypia, split by abundant extracellular myxoid matrix. The patient showed a satisfactory evolution without evidence of recurrence.
Conclusions: intramuscular myxomas are a less frequent slow growing and painless tumors. Complete removal is the treatment of choice. Nowadays there are not cases of malignancy and its recurrence is due to incomplete resection. The final diagnosis can only be achieved by histological study. The presented case had a favorable evolution after two years of surgery without recurrence.
