case_images: C3 and C4, and ESR improved, but the palatal ulcer worsened, resulting in perforation of the hard palate (Figure 1). CT showed the palatal perforation (Figure 2).
case_images: CT showed the palatal perforation (red arrow).

case_images: A nasal endoscopic biopsy was performed and histopathology showed an inflammatory polyp with chronic suppurative inflammation and inflammatory granulomatous hyperplasia (Figure 3).
case_images: Immunohistochemical tests of nasal biopsy were negative. (A) EBER. (B) Ki-67. (C) CD19. (D) CD20. (E) TIA-1. (F) CD8. (G) CD3. (H) CD2. (I) CD56. (J) CD79a. (K) CD7. (L) CD4. (M) Granzyme B. (N) Pax-5.

case_images: So we performed immunohistochemical tests of CD3, CD56, CD2, CD4, CD5, CD7, CD79a, CD8, CD19, CD20, PAX5, TIA-1, Ki-67, EBER, and Granzyme B were negative (Figure 4).
