Muscle weakness in a 4-year-old girl: A rare presentation of deep morphea

Introduction: Morphea is a rare fibrosing disorder of the skin and underlying tissues. Deep morphea involves the deep dermis, subcutis, fascia, muscle, and bone. The above structures may be involved independently or in combination. Case report: We describe a case of deep morphea presenting as muscle weakness, independent of skin lesions, in a child with generalized morphea. Discussion: Muscle weakness, even in the absence of overlying or progressive skin sclerosis, can be deep morphea, especially when segmental and associated with atrophy.
