Pseudoachalasia as a paraneoplastic event in a patient with Hodgkin's disease.

Pseudoachalasia or secondary achalasia (5% of achalasias that are deemed primary achalasias) is an esophageal motor disorder with manometric criteria for achalasia, but it appears in the context of an underlying pathology that can be attributed to its origin. Usually appears in >60 years with rapid evolution of symptoms (<1 year). The main cause of pseudoachalasia is neoformative etiology, but there are others.
