A Case of Solitary Malignant Schwannoma with Regiomal Lymphnode Metastasis / 대한피부과학회지

ABSTRACT

Malignant schwannoma is a rare spindle cell tumor derived from schwann cells. There is no significant age or sex distribution. The typical clinical presentation is that of a painless slowly enlarging soft tissue mass, occasionally associated with a peripheral neuropathy. Tumors tend to recur lacally and eventually metastasize, commonly to the lung. We report a case of solitary malignant schwannoma with metastsis to the regional axillary lymph nodes. The patient is a 50-year-old male who had the recurred tumor on right upper arm and child fist sized palpable painless mass on right axilla, which were confirmed to be malignant schwannoma and. lymph node metastasis. But we could not find any evidence of pulmonary metastasis. Tumor and metastatic lymph nodes were widely excised and skin graft was performed.
