[Multiple mononeuropathy associated with systemic sclerosis with vasculitis confirmed by nerve biopsy: a case report]

Abstract

A 68-year-old woman with a medical history of interstitial pneumonia associated with systemic sclerosis (SSc) presented with numbness of the lower limbs and left drop foot. She was diagnosed with multiple mononeuropathy based on the laterality of her symptoms, muscle weakness, thermal hypoalgesia, and nerve conduction study findings. Left sural nerve biopsy showed vasculitis, and steroid therapy was effective. This case highlights the importance of histopathological assessment to select an appropriate treatment strategy.
