title: A challenging case of multiply recurrent nasal basal cell carcinoma.
abstract: BACKGROUND
  Basal cell carcinoma (BCC) is the most common human malignancy worldwide and represents a significant cost to health care systems. Most cases occur on the head and neck, and many are successfully treated with relatively simple measures. However, if high-risk or complicated cases are not treated effectively, they may result in considerable disfigurement or morbidity. We report on a patient with a complex nasal basal cell carcinoma (BCC) that failed multiple treatments by electrodesiccation and curettage (EDC). Management strategies for primary and recurrent BCC, including EDC, standard excision, Mohs micrographic surgery (MMS), and radiation therapy, are discussed. This case required extensive resection, and we review the literature for predictive factors of significant subclinical spread.
  
  
  OBJECTIVE
  To present a complex case that illustrates the management options of high-risk, recurrent BCC of the head and neck.
  
  
  METHODS
  Case report and review of the literature.
  
  
  RESULTS
  MMS offers the lowest recurrence rate in the treatment of recurrent BCC in surgical candidates. A validated risk scale may predict subclinical spread in patients with BCC of the head and neck.
  
  
  CONCLUSIONS
  BCC can progress to locally advanced disease, necessitating definitive treatment. EDC performed by an experienced dermatologist may offer cure rates comparable to those of surgery in lower-risk BCC. However, in higher-risk tumors, such as recurrent or larger lesions, methods that ensure clear margins should be considered first line, especially in sensitive locations. The routine use of a validated risk scale can better prepare patients and dermatologists for potentially extensive resections. In cases with risk of extensive involvement, strategies to clearly communicate options and progress at all stages of the process should be available.
