title: Late inguinal metastasis of a well-differentiated subungual squamous cell carcinoma after radical toe amputation.
abstract: BACKGROUND
  Although squamous cell carcinoma (SCC) is commonly found on sun-exposed skin, this malignancy in nail beds is rare. There is a very low rate of metastases, especially for well-differentiated lesions without bony involvement.
  
  
  OBJECTIVE
  To present a case of late inguinal metastasis after radical toe amputation 3 years previously for subungual SCC.
  
  
  METHODS
  Case report.
  
  
  RESULTS
  The patient received modified inguinal lymphadenectomy and adjuvant radiation therapy. No recurrence or metastases were observed for 12 months.
  
  
  CONCLUSIONS
  For patients with subungual SCC postsurgery, it is important to regularly evaluate for a minimum of 3 years, despite the very low rate of metastases.
