title: [Clinical and radiological diagnosis considerations on 2 cases of achalasia].
abstract: Two cases of achalasia of the lower third of the oesophagus are presented. Leucoplakia was encountered in one of the cases. The clinical, aetiopathogenic and x-ray diagnostic aspects of achalasia are described in relation to the possibility that it may be associated with neoplasia or pre-cancerous alterations. In both the above cases, early dysphagia was encountered.
