Basal cell carcinoma (BCC) primarily develops in the head and neck region, with 74–83 per cent of BCC occurring in this region. Unfortunately, most published studies on BCC were conducted in Caucasian populations, and analytic data on extra-facial BCC in Asian and Korean patients, in particular, are not readily available. Here, we report on a retrospective analysis of extra-facial BCC in Korean patients. Thirty-five patients (16 men, 19 women) diagnosed with extra-facial BCC at Chonbuk National University Hospital between January 1981 and December 2008 were evaluated. Their average age was 62.3 years and most of the patients (11 of 35, 31%) were in their fifties. The relative tumour density (RTD) was the highest in the genitalia (0.769), followed by the axilla (0.481). Other regions such as the trunk, buttocks and upper and lower extremities exhibited a much lower RTD (average: 0.1). Histopathological examinations showed that 16 tumours were nodular (46%), eight were superficial (23%) and seven were mixed (20%). Additionally, potential predisposing factors were identified in seven cases. In five patients the use of Asian medicine, including acupuncture and herbal medication, was ascertained. To the best of our knowledge, the present study is the first to analyse the clinical and histopathological characteristics of extra-facial BCC in Korean patients. Our results indicate that the incidence of extra-facial BCC is higher in the axilla and genitalia than at other locations, although these sites are frequently overlooked during routine skin examinations. |
