Cobalamine deficiency associated with neuropathy and oral mucosal melanosis in untreated gluten-sensitive enteropathy. Indian Journal of Gastroenterology. 2005 May-Jun; 24(3): 120-2http://imsear.searo.who.int/handle/123456789/65249A 32-year-old woman was admitted with complaints of difficulty in walking and hypoaesthesia and tingling in her legs. She had short stature and brown-black hyperpigmentation, cheliosis, dental irregularities and scars in the axillary regions. Neurological examination revealed mild, symmetric, predominantly distal weakness of the legs; deep tendon reflexes were depressed. There was glove-and-stocking decrease in pinprick and temperature perception but proprioception and light touch were normal. Investigations established a diagnosis of celiac disease; her neurological features improved on gluten-free diet, but oral pigmentation persisted.engAdultBiopsyCeliac Disease --complicationsFemaleHumansMelanosis --etiologyMouth Mucosa --pathologyNeurocutaneous Syndromes --etiologyPeripheral Nervous System Diseases --etiologyVitamin B 12 Deficiency --etiologyCase Reports
