Abstract:
Lichen myxedematosus (synonym, papular mucinosis) is a disorder characterized by lichenoid papules, nodules and plaques due to dermal mucin deposition, and a variable degree of fibrosis without thyroid dysfunction. Discrete lichen myxedematosus is a subtype of the localized lichen myxedematosus. Clinically, firm, smooth, waxy or flesh-colored papules measuring 2 to 5 mm in diameter, numbering just a few to hundreds, and involving limbs and trunk. The lesions progress slowly without systemic symptoms and rarely resolve spontaneously. Histologically, the upper and mid dermis shows edema and diffuse or focal mucinous deposit under normal epidermis. Fibroblast proliferation is variable, but there is neither collagen deposition nor sclerosis. On experiencing a case of discrete grouped papules on the arm and thigh of a sixty three year-old women, we present it as discrete lichen myxedematosus.
