“…El diagnóstico diferencial de un teratoma gástrico, donde exista una masa calcificada, debe hacerse con nefroma mesoblástico, neuroblastoma, hemangioepi-telioma, hepatoblastoma, tumor de Wilms y teratoma retroperitoneal. Otros diagnósticos menos frecuentes incluyen quiste pancreático, quiste de epiplón, quiste de mesenterio, duplicación quística, quiste esplénico, liposarcoma, pólipos adenomatosos, leiomiomas y lipomas 13 .…”

Introducción: Reportamos los hallazgos clínicos, quirúrgicos, imagenológicos e histopatológicos de un paciente con Teratoma Gástrico.Materiales y método: Se recopilaron variables clínico demográficas, imagenológicas, quirúrgicas y post operatorias, analizándolas de forma descriptiva.Resultados: Paciente masculino de 33 años que presenta cuadro de TVP (trombosis venosa profunda) que se decide complementar con Angiotc donde se constata aumento de volumen nodular en relación a la curvatura menor del estómago. Se complementa estudio con endoscopía digestiva alta que muestra lesión infiltrante, extensa en curvatura menor. Se decide realizar gastrectomía total laparoscópica. Estudio histopatológico muestra en curvatura menor, histopatología compatible con teratoma maduro. Paciente con evolución satisfactoria post operatoria se decide alta médica, control a los 7 meses post operado sin complicaciones.Discusión: El teratoma gástrico es un tumor infrecuente, se caracteriza por su composición heterogénea. Se diagnostica comúnmente en niños pequeños, aunque puede ocurrir a cualquier edad. La causa exacta del teratoma gástrico es desconocida, pero se cree que se desarrolla debido a anomalías durante el desarrollo embrionario. Su diagnóstico de teratoma implica una combinación de estudios. Histológicamente, los teratomas gástricos están compuestos de tejidos de diferentes capas de células germinales, incluyendo ectodermo, mesodermo y endodermo.Conclusión: los teratomas gástricos son tumores extremadamente inusuales, que pueden ser difíciles de diagnosticar y manejar, se requiere un enfoque multidisciplinario para un manejo óptimo.

“…An immature gastric teratoma in a newborn may be a part of the spectrum of congenital tumors [10][11][12][13][14]. Since the presence of teeth or bone, which is pathognomonic for teratoma, is less frequently present in gastric teratoma, most gastric teratomas are frequently diagnosed preoperatively as a neuroblastoma, Wilms' tumor, mesoblastic nephroma, rhabdomyosarcoma, liposarcoma, or retroperitoneal teratoma [8,[15][16][17].…”

Among the subtypes of germ cell tumors, teratomas are the most frequent in the pediatric population and commonly occur in the sacrococcygeal region and the gonads. Less than 1% of all teratoma are found in abdominal organs including the stomach, liver, and kidney. Gastric teratomas are very rare tumors predominantly found in infants. Moreover, an immature gastric teratoma is exceptionally rare. Here, we present a case of immature gastric teratoma with spontaneous rupture in a newborn who was preoperatively diagnosed with neuroblastoma. On the first day after birth, the neonate presented with progressive abdominal distension accompanying respiratory distress. A firm mass was detected during a physical examination of the abdomen. An emergency exploratory laparotomy revealed hemoperitoneum resulting from a rupture of the tumor located in the posterior wall of the gastric antrum. Complete resection of the tumor and gastroduodenostomy were performed. The pathology evaluation revealed a grade 3 immature gastric teratoma with no malignant components. The patient was treated with adjuvant chemotherapy to prevent recurrence, since the tumor was ruptured in the abdominal cavity and the level of alpha-fetoprotein was decreased but still remained high above the normal range after surgery. In conclusion, physicians should be aware of the existence of gastric teratoma as the differential diagnosis of a huge abdominal mass in infants, especially neonates. Complete surgical removal of the tumor and long-term follow-up has been adopted as the standard management for immature gastric teratoma, although there has been controversy with adjuvant chemotherapy.

Imaging findings of gastrointestinal tract tumors in children and adolescents

et al. 2022

Gastrointestinal (GI) tract tumors are rarely seen in children and adolescents, and can easily be misdiagnosed. Lymphoma is the most frequent GI tract tumor, and the common locations are ileum and ileocecal area. GI tract tumors may present as large heterogeneous mass lesions. For gastric and colonic tumors, increased wall thickening usually prompts the diagnosis of GI tract tumors. Computed tomography and magnetic resonance imaging might be used in clinically suspected cases for correct/appropriate diagnosis and management. Awareness as regards the most common tumors and their locations is paramount for radiologists. Likewise, the aim of this article was to define the imaging findings of primary benign and malignant GI tract tumors in children and adolescents.
