RESUMO
Germ cell tumors (GCTs) are considered as extragonadal if there is no evidence of a primary tumor in the testes or ovaries. GCTs can be classified as seminomas, non-seminomatous, mature teratomas, and immature teratomas based upon histology. Mature teratomas are generally found in prepuberal children. Less than 1% of them have been reported in the gastrointestinal tract and liver. Liver teratomas are extremely rare. There are only 11 cases reported in adults up to 2018. Isolated liver metastasis of ovarian teratoma is also very rare. We present a case of a late metachronous recurrence of liver cystic teratoma with gliosis peritonei in a female adult treated by a right extended hepatectomy along with a literature review.
RESUMO
El angiomiolipoma hepático es un tumor mesenquimatoso infrecuente perteneciente al grupo de los PEComas (Perivascular Epithelioid Cells), que cuenta con un potencial maligno indeterminado. Los síntomas clínicos son inespecíficos, siendo las características radiológicas principales la alta vascularización de la lesión y la presencia de tejido adiposo macroscópico. Presentamos un caso clínico de un angiomiolipoma hepático izquierdo diagnosticado por tomografía computada de manera incidental y asintomático en una paciente sin antecedentes de importancia que se sometió a hepatectomía lateral izquierda con resección completa del tumor, el cual fue negativo para malignidad y sin complicaciones.Hepatic angiomyolipoma is a mesenchymal tumor known as PEComas (Perivascular Epithelioid Cells) with unknown malignancy pattern. We present a case report of left hepatic angiomyolipoma diagnoses by computed tomography in an asymptomatic patient with no previous medical diseases. The tumor was complete resected during a left lateral hepatectomy with no complications and final histologic report was negative to cancer.
