A case of leiomyosarcoma of the nasal cavity and paranasal sinuses is presented along with a review of the medical literature. The clinicopathological aspects of this tumor are discussed. The mode of treatment is complete surgical excision with close follow-up due to its high rate of local recurrence. The long-term survival with recurrent disease in this case is unusual.
Morphologic evidence of intercellular junctions was found between polymorphonuclear leukocytes (PMNs) and between PMNs and tumor cells. All these junctions displayed electron-dense plaques along the plasma membranes with linear spaces in between. These plaques were finely granular and devoid of filaments. Fine granules were also observed in some of these linear spaces. The significance of these morphologic findings is not known but may be elucidated by a correlative type of study.
