Introduction: Aneurysmal bone cyst (ABC) are benign tumor-like lesions of the bone that occur at any age with a slight female predominance. The most sites are long bones and vertebrae bodies. Materials and Metods: We report a case of 54 year-old man with nasal respiratory difficult and a previous history of nasal fracture. RMN and TC-scan showed a voluminous nasal lesion, which was surgically removed. Tissue sample was formalin fixed (10%) and routinely processed to paraffin after decacifying treatment (Osteodec, Bioptica). Section were stained with haematoxilin-eosin. Results: At histological level the lesion was characterized by multilocular cyst-like spaces filled with eritrocytes separated by connettival septa lacking the smooth muscle walls and endothelial linig of normal vessels. Histological features are consistent with a diagnosis of ABC. Discussion: We report a case of ABC of nasal cavity. The previous history of nasal fracture and the fact that pre-existing or concurrent were not found lead us to suppose a relationship between the fracture and ABC. Teleangiectatic osteosarcoma, fibrous dysplasia and giant-cell tumor were excluded according to clinical and morphological features.
