What tissue level does metastatic melanoma reach?

Explanation:
Melanoma spreads most readily through the skin’s local environment, so metastasis often settles in nearby soft tissues. The subcutaneous layer lies just beneath the dermis and provides a receptive space for circulating tumor cells to lodge and grow as nodules. While deeper tissues, bones, and distant organs can be involved as disease progresses, the tissue level most characteristic of initial metastatic spread from a cutaneous melanoma is the subcutaneous tissue.
