Intramuscular metastasis of cutaneous squamous cell carcinoma: a case report.
Cutaneous squamous cell carcinoma (SCC) is a common cancer. Although most patients with primary cutaneous SCC have an excellent prognosis, for those with metastatic disease, the long-term prognosis is poor. The most common sites of metastasis are regional lymph nodes, lung, liver, brain, skin, and bone. However, metastatic soft tissue SCC from cutaneous lesions is extremely rare, with only two reported cases. We report a case in which the patient had a primary SCC lesion on his left palm in 1986. A second primary SCC on his left forearm was confirmed in 2001, with subsequent metastasis to the proximal muscles and bone invasion in spite of the initial wide excision.
