C. Morphea (Localized scleroderma)
Discussion of Answer
Morphea is a localized form of scleroderma characterized by firm plaques that can occur in women and men, in children and adults. The eruption typically starts out as pink- to
rose-colored patches followed by hard, slightly depressed, yellow-white patches and plaques with surrounding hyperpigmentation. The trunk is the most common location, but
morphea can occur anywhere. Within the plaque, the elasticity of the skin is lost, making the area feel rigid.
A variant of localized morphea is guttate morphea, which appears as small, chalky-white, slightly depressed macules that may erupt on the upper chest, shoulders, and neck.
This type of morphea can resemble lichen sclerosus. The association is important because there are some patients who develop both morphea and lichen sclerosus
Morphea may become generalized, with confluent lesions involving multiple extremities, the trunk, and face. Generalized morphea should be distinguished from scleroderma;
there is no systemic or internal involvement in generalized morphea.
steroid injections localized to the plaque in an attempt to soften the plaque and decrease the potential for spread. Ultraviolet light, in the form of PUVA (psoralen and UVA), can
be used in severe, generalized cases. Some have advocated using oral calcitriol and topical calcipotriene.
