In this case report, a 61-year-old male presented with odynophagia and ulceration in palatum durum after inhalating dust from machinery containing a weak acid. It was at first diagnosed as an acidic ulcer due to two biopsies verifying this. Because of progressing ulceration a third biopsy was taken - this time with the diagnosis extranodal NK/T-cell lymphoma, nasal type. This illustrates the diagnostic challenges of the illness, typically requiring multiple biopsies, and one should have this differential diagnosis in mind in case of progressing ulceration.
