mycosis fungoides patch

(my-KOH-sis fun-GOY-deez …)
A flat, thin, pink or red patchy rash that forms on the skin of patients with a type of skin lymphoma called mycosis fungoides. The patches may be dry, scaly, and itchy and may look like eczema or psoriasis. They can occur anywhere on the body, but they are most common on the lower abdomen, upper thighs, buttocks, and breasts. The patches may sometimes become plaques (hard, raised lesions) on the skin.
