KROK 1 2013 – Question 81 · KROK (Medicine) · Pathomorphology
A patient underwent biopsy of the soft palate arches for a suspected tumor (macroscopy revealed an ulcer with a dense floor). Study of the biopsy material revealed mucosal necrosis with infiltration of lymphocytes, epithelioid cells, plasma cells, single neutrophils in the submucosa. There were also apparent signs of endovasculitis and perivasculitis. The described changes are typical for:
- A. Necrotizing ulcerative Vincent stomatitis
- B. Ulcerative stomatitis
- C. Aphthous stomatitis
- D. Primary syphilis
- E. Pharyngeal diphtheria
Hint
Combine the dense ulcer floor, the plasma cell-rich infiltrate and the inflammation around and within vessel walls to decide which kind of lesion this is.
