  • Abstract
  • Look Inside

“Blutbeule” in the maxillary sinus was initially reported by Tadokoro in 1917, and it represented a kind of pseudo-malignant lesion.

The chief complaints of patients with “Blutbeule”were unilateral nasal obstruction and epistaxis. CTscans demonstrated a heterogeneous soft tissue mass occupying the entire unilateral maxillary sinus and thinning of the maxillary bone. MR images of two cases showed a well-preserved mucous mem-brane of the maxillary sinus, differentiating it from malignant lesions.

All three patients underwent endoscopic sinus surgery and the tumorous masses were extirpated. The histopathological findings showed necrosis, proliferating capillaries, hemorrhage and hyaline degeneration without any evidence of malignancy.
