title: Epidermotropic chondroid metastasis of melanoma: report of a case of metastatic melanoma with previously unreported morphological features.
abstract: A potential diagnostic pitfall in the management of patients with melanoma is the inability to recognize metastatic melanoma, especially if it shows unusual features. We describe a case of multiple epidermotropic metastatic melanoma, which finally recurred with an extensive chondroid differentiation. To our knowledge, this is the first description of a case of epidermotropic chondroid metastatic melanoma.
