A case report of variegate porphyria

: We reported a 30-year-old woman with variegate porphyria. Family history disclosed that her mother had the same skin lesions as the present case. She has had repeated vesicles and brownish pigmentation on her upper extremities since eighteen years of age. Recently she was suffering from common cold, and was treated with drugs. One week later, she started to develop weakness and dysesthesia in all limbs, hallucination, and urinary disturbance. Three weeks later, she was admitted to our hospital because she could not stand any more. On general examination, she had brownish pigmentations and crusts in hands and forearms. Neurologically she had moderate weakness, dysesthesia and hyperreflexia in all limbs. Urine was dark-red. Head and cervical MRI was normal. Nerve conduction studies and somatosensory evoked potentials were within normal limits. Excretion of porphyrins, especially protoporphyrin and X-porphyrin in the feces were markedly increased, and the diagnosis of variegate porphyria was made. Intravenous administration of glucose was effective and her symptoms began to improve in two weeks after her admission. However, recovery of weakness took two months and dysesthesia did not disappear in three months. We considered that her clinical manifestations were caused by involvement of the central and peripheral nervous systems.
