Presentación polipoide de un carcinosarcoma primario de vagina. Un caso clinicopatológico de esta neoplasia excepcional

Introduction

Gynecological carcinosarcoma, also called malignant mixed Müllerian tumor, is a rare, heterogeneous, aggressive, malignant neoplasm. The vagina as a primary site of carcinosarcoma is exceptional.

Main symptoms and/or clinical findings

95-year-old woman who consulted for vaginal bleeding. The gynecological examination revealed a polypoid tumor dependent on the right lateral wall of the vagina.

Main diagnoses, therapeutic interventions and results The CT radiological study identified a tumor measuring 6 × 3,4 × 3,5 cm, which occupied the lower third of the vagina. The polypoid mass was excised in fragments, with resection of its base in the right medial 1/3 of the vagina. The histological study corresponded to a malignant spindle-cell neoplasm with areas of high cell density, intersecting fascicles and multiple edematous areas, with spindle-shaped or stellate-shaped cells with intense nuclear atypia and monstrous bizarre cells. Chondroid-like or myxoid appearance foci, frequent atypical multinucleated giant tumor cells, mitosis and some foci with evident epithelial differentiation in the form of poorly differentiated carcinoma were observed. The diagnosis was carcinosarcoma. Considering the patient's age, it was decided to perform follow-up without further interventions. Currently, one year after diagnosis, the patient has no evidence of recurrence.

Conclusion

Primary malignant neoplasms of the vagina are very rare. Vaginal carcinosarcoma is an extremely rare neoplasm that occurs in elderly women. The prognosis is poor and more studies are needed to better understand this neoplasm.
