Basal cell carcinoma (BCC) is the most common skin cancer, occurring more frequently than malignancies of any other tissue or organ with a steadily increasing incidence. Ultraviolet radiation is considered the single most important risk factor for BCC. Additional risk factors include exposure to arsenic, coal tar derivatives, irradiation, scars, burn sites, chronic inflammation, ulcers, and immune deficiency.
BCC arises commonly on sun-exposed sites such as the head and neck and occurs infrequently on non-sun-exposed sites such as the axilla, buttock, groin, penis, scrotum, vulva, breast, and nipple. Among these, the occurrence of BCC in the axilla is extremely rare, and to date, only 5 cases have been reported in Koreans (Table 1). BCC can be classified histologically into nodulocystic (nodular), mixed, infiltrative, superficial, micronodular, adenoid, metatypical, morpheaform and fibroepith- elioma type. The occurrence of adenoid BCC is relatively low compared to the nodulocystic BCC, which is the most common type of BCC2. We herein report a rare case of adenoid basal cell carcinoma in the axilla in a 33-year-old woman. kamagra tablets
