Resumen
JIMENEZ-HERRERA, Rebeca et al. Collision tumor in the ovary, with fibrothecoma. Case report. Ginecol. obstet. Méx. [online]. 2022, vol.90, n.5, pp.466-471. Epub 12-Sep-2022. ISSN 0300-9041. https://doi.org/10.24245/gom.v90i5.6228.
BACKGROUND:
The temporal-spatial coincidence of two or more benign, malignant or combined neoplasms that affect the same organ or tissue is what defines the collision tumor, with behavioral, genetic and histological differences. Ovarian collision tumors are a rare subtype.
CLINICAL CASE:
A 53-year-old patient, who came to the Emergency Department due to intermittent pain of seven months' evolution, which, in recent weeks, intensified and nausea and vomiting were added. During abdominal examination, an increase in volume was detected in the pelvic area, without peritoneal irritation. Tumor markers: CA-125, CA 19-9 and carcinoembryonic antigen were reported in normal parameters. Pelvic ultrasound reported the existence of a simple and complex cystic image, with a solid component. Pathological anatomy examination diagnosed: collision tumor in the left ovary.
CONCLUSION:
Collision tumors in the ovary are rare according to reports in the literature. A thorough pathological diagnosis and adequate clinical-radiological follow-up are necessary to rule out colliding tumors.
