Answer

In long-standing lesions, lichenification and hyperpigmentation may occur as a consequence of chronic scratching and rubbing. In addition, patients with chronic stasis dermatitis can show changes, such as skin induration, that may progress to lipodermatosclerosis (with the classic inverted champagne bottle appearance). [28]

Another unique feature sometimes seen in chronic stasis dermatitis is the development of violaceous plaques and nodules on the legs and the dorsal part of the feet. These lesions frequently undergo painful ulceration and can be clinically indistinguishable from classic Kaposi sarcoma. This clinical appearance has led this entity to be called pseudo–Kaposi sarcoma or acroangiodermatitis.
