A 54-year-old woman visited another hospital with complaining of a palpable mass in vagina and dysuria. The mass had gradually enlarged since the past 2 years.
Ultrasonography and CT revealed the tumor located between the urethra and vaginal mucosa. Histopathological examination was well-differentiated leiomyosarcoma from transvaginal needle biopsy. She was referred to our hospital. On MRI, the 4-cm tumor showed no infiltration into the vaginal mucosa or urethra. PET/CT showed a high uptake of FDG. No metastatic disease was evident. We performed excision of the tumor transvaginally. The tumor cells demonstrated immunoreactivity for estrogen receptors and partially progesterone receptors in histopathological examination. We speculated that the developmental mechanism of female paraurethral leiomyosarcoma was associated with female leiomyosarcoma in other surrounding pelvic organs.
