We report a rare case of cellular leiomyoma in the nasal cavity. A 72-year-old Japanese
woman was admitted to a hospital. A tumoral lesion was revealed in the left nasal cavity.
Angiography showed tumor staining, and the tumor was endoscopically resected after the
embolizaion of the feeding artery. At gross inspection, the tumor measured 1.0
× 1.5 × 2.0 cm. Microscopically, the tumor consisted of many spindled cells with blunt ended nuclei.
Immunohistochemical examination revealed that the tumor cells were positive for
vimentin, alpha smooth muscle actin. We diagnosed this case as cellular leiomyoma. To
the best of our knowledge, there have been only 23 reported cases of nasal leiomyoma in
English medical literature. We made a brief literature review of the occurrence of this
tumor in the nasal cavity.
Key words: cellular leiomyoma; nasal cavity
