Lymphatic compression by sclerotic patches of morphea: an original mechanism of lymphedema in a child.
Lymphedema in children is mostly primary, due to lymphatic hypoplasia. Secondary lymphedema is caused by lymphatic injury or obstruction. We report the case of a child that developed a lymphedema of the left upper and lower extremities, with a simultaneous onset of ipsilateral hemicorporal morphea. We concluded that lymphatic obstruction was due to sclerosis from morphea. This is a unique, rarely reported mechanism of lymphedema. Lymphoscintigraphy revealed attenuated lymphatic flow in the left upper and lower limbs. Systemic corticosteroids were associated with slow improvement in the sclerotic patches. We simultaneously noticed an improvement in the lymphedema of limbs. Repeat lymphoscintigraphy revealed dramatically improved lymphatic function. This case suggests that at least in some cases lymphedema may be caused by morphea.
