ABSTRACT

Resumen ANTECEDENTES: El coriocarcinoma es una neoplasia maligna del epitelio trofoblástico, agresiva pero susceptible de curación, incluso cuando hay metástasis. Puede ser de origen gestacional o no, el primero aparece después de un embarazo molar o aborto. CASO CLÍNICO: Paciente de 14 años, acudió a Urgencias debido a un cuadro de abdomen agudo, con prueba en orina positiva de embarazo; además, una tumoración en la región anexial derecha. En la laparotomía se encontró una tumoración dependiente del anexo derecho, con la cápsula rota, adherida al colon. Un día después de la intervención quirúrgica (por no contar con recursos en la unidad) se tomó la fracción beta de gonadotropina coriónica. El diagnóstico definitivo se estableció con base en el reporte del estudio histopatológico de la pieza quirúrgica. CONCLUSIÓN: El coriocarcinoma es una neoplasia maligna del epitelio trofoblástico, muy agresiva pero susceptible de curación, incluso cuando se detectan metástasis. La incidencia en México de coriocarcinoma gestacional es de 0.133 por cada 100,000 mujeres, mientras que la incidencia del cariocarcinoma no gestacional se desconoce. Se reporta como un tumor muy raro; por ello el diagnóstico preciso y oportuno es difícil en este tipo de tumores; la presentación más habitual es el abdomen agudo.


Abstract BACKGROUND: Choriocarcinoma is a malignant neoplasm of the trophoblastic epithelium, very aggressive but highly curable, even when there is metastasis. It can be of gestational and non-gestational origin, the first one can develop after a pregnancy, abortion or molar pregnancy; in Mexico it is calculated with an incidence of 0.133 per 100,000 women. While the incidence of non-gestational choriocarcinoma is unknown as it is reported as a very rare tumor. The objective is present the first case reported in our hospital, there are few cases reported in Mexico, it is important to know them in order to identify, diagnose and refer them on time. CLINICAL CASE: A 14-year-old patient who presented to the emergency department with a picture of acute abdomen with pregnancy test in positive urine and tumor in the right adnexal region, laparotomy was performed, finding a tumor dependent on the right annex with a broken capsule attached to the colon, one day after the surgical event (due to lack of resources in the unit) beta fraction of chorionic gonadotropin, the definitive diagnosis was made by the histopathological study of the surgical piece. CONCLUSION: Choriocarcinoma is a malignant neoplasm of the trophoblastic epithelium, very aggressive but highly curable, even when metastases are detected. In Mexico, the incidence of gestational choriocarcinoma is 0.133 per 100,000 women, while the incidence of non-gestational cariocarcinoma is unknown, it is reported as a very rare tumor, which is why accurate and early diagnosis is difficult in this type of tumors. , since the most common presentation is an acute abdomen.
