RESUMEN
An 83-year-old woman presented to a rural general hospital with urinary incontinence. She was diagnosed with complete labial fusion caused by genitourinary syndrome of menopause. She was successfully treated with surgical separation followed by hydrocolloid dressings. Genitourinary syndrome of menopause often remains undiagnosed due to patient embarrassment. Greater recognition of this condition in primary care can improve patient access to appropriate treatment and improve quality of life.
RESUMEN
Primary vaginal carcinosarcoma (VCS) is an extremely rare and aggressive tumor consisting of admixed malignant epithelial and mesenchymal elements. We report a case of VCS that was subjected to analysis by immunohistochemistry and next-generation sequencing (NGS). A 53-year-old woman with post-menopausal vaginal bleeding underwent surgical excision followed by concurrent chemoradiation. A well demarcated tumor was growing in a discontinuous fashion at a location some distance from both the cervix and vulva. Microscopically, the tumor consisted of adenocarcinoma components and sarcoma components consisting of a sheet-like growth of spindle-shaped cells, and we diagnosed this tumor as primary vaginal carcinosarcoma. NGS analysis of each component identified the following variants, TP53, PIK3CA, KRAS and FBXW7. A comparison of microsatellite instability (MSI) and tumor mutation burden (TMB) showed that within both tissues the sarcomatous components had a higher MSI and TMB than the carcinomatous components. This case supports "a monoclonal theory" with the genome profile being similar to other malignant mixed Müllerian tumors.
