In-transit metastasis from primary cutaneous squamous cell carcinoma in a nonimmunosuppressed patient.

BACKGROUND: In-transit metastases are dermal and subcutanous metastatic foci located between the tumor and the closest regional lymph node. Although in-transit metastasis has been commonly described for malignant melanoma, there have been some reports of in-transit metastases arising from primary cutaneous malignancies. The risk of development of in-transit metastases is higher in patients with high-risk squamous cell carcinoma. CASE REPORT: We present a case of in-transit metastasis in a nonimmunosuppressed patient with a primary cutaneous squamous cell carcinoma.
