Basal cell carcinoma on the dorsum of the foot with inguinal and pelvic lymph nodes metastases.

Background Although basal cell carcinoma (BCC) is the most common type of skin cancer, the incidence of metastasis is exceedingly low. Objective Case presentation of a basal cell carcinoma arising on the dorsum of the foot with inguinal and pelvic lymph node metastases. Method Case presentation with literature review. Result On the basis of our review of Japanese literature, the risk factors for BCC metastasis are occurrence on the genitalia, diameter of more than 3 cm, deep invasion of tumor cells into extradermal structures, and infiltrative/morpheic histological type. Conclusion Although metastasis from BCC is extremely rare, the prognosis of metastatic BCC is often poor. Careful follow-up is recommended in cases with high risk factors. [ABSTRACT FROM AUTHOR]
