Schamberg's disease is a skin disorder that causes a discoloration of the lower extremities. [4] It usually occurs in the lower extremities and rarely elsewhere.

[3] On the surface of the skin, these areas may range in size from small patches, to plaques (larger, raised areas), to neoplasms (spreading, tumor-like ...
Such cells might then aggregate into a spot with an irregular shape. [13] They propose that the protrusion of a flat spot is a result of the death of aged cells in the spot and release of lipofuscin bodies. [13] The aggregating cells would form a capsule, and the dense lipofuscin bodies make the protruding spot soft and dark in color. [13]
