Simultaneous Occurrence of Neuromyotonia and Morphoea: A Cause-Effect Relationship?

The document reported a case of a 32-year-old man who simultaneously experienced neuromyotonia and morphoea, also known as localized scleroderma, in the same limbs. The patient had a 2-year history of muscle twitching in the right limbs, accompanied by hair loss and skin tightness in those areas. Examination revealed almost complete hair loss on the right arm, forearm, hand, and parts of the right lower limb, particularly the back of the thigh and calf. This case highlighted the unusual co-occurrence of these two conditions in the same regions of the body.
