Radiological manifestations of oesophageal involvement in acanthosis nigricans.

Radiologic features of two cases of acanthosis nigricans with oesophageal involvement are reported. The first case demonstrated diffuse, granular shadows throughout the oesophagus which were difficult to differentiate from oesophageal moniliasis. Another case showed many discrete and tiny elevations resembling pseudopolyposis of the colon. Emphasis is placed on radiological differential diagnosis from moniliasis and leukoplakia of the oesophagus.
