Hemangiomas are common benign soft tissue tumors in the head and neck, but they occur infrequently in the sinonasal cavity. seen and are composed of thickened blood vessels that can still be recognized as veins. Chief symptoms are recurrent epistaxis and nasal obstruction; if the tumor becomes large, it may cause adjacent bony erosion. Preoperative diagnosis of maxillary sinus hemangioma is important since these lesions can frequently cause a large amount of hemorhage during surgery. We report a venous hemangioma.

Background and Objectives: The role of different Galectins in the pathogenesis of different types of malignancy is being profoundly investigated recently. In this study, the author investigated the level of Galectin-1 and -7 in the layngeal squamous cell carcinoma tissue to define its relationship to the tumor progression. Materials and Methods: Paraffin-embedded tissue specimens from 77 patients, who were diagnosed as laryngeal squamous cell carcinoma from 1993 to 2007, were immunohistochemically stained for Galectin-1 and -7. Results: Galectin-1 expression was positively correlated with tumor stage and nodal involvement. Galectin-7 expression was increased in better differentiated tumors. Conclusion: Expression of Galectin-1 and -7 can be used as a valuable indicator in laryngeal squamous cell carcinoma under certain limitations.
