Epidermotropic chondroid metastasis of melanoma: report of a case of metastatic melanoma with previously unreported morphological features.

A potential diagnostic pitfall in the management of patients with melanoma is the inability to recognize metastatic melanoma, especially if it shows unusual features.

To our knowledge, this is the first description of a case of epidermotropic chondroid metastatic melanoma.
