A 17-year-old girl presented with several years history for pigmented plaques on her abdomen and upper extremities. She had not any other significant medical problem. 

What is your diagnosis? 

Diagnosis: Morphea

Classically morphea is considered as a localized form of scleroderma. It is characterized by a well demarcated plaque with a smooth appearance which is usually indurated on palpation. Morphea is more common in females.

Usually, localized morphea is not a diagnostic problem but its treatment is generally disappointing. Asymptomatic plaques should probably be left alone to resolve spontaneously.
