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.
