ABSTRACT

Perivascular epithelioid cell neoplasms (PEComas) are a tumor family defined as such just a couple of decades ago. They make an unusual group of neoplasms, which can appear in different locations of the organism. PEComas are usually considered to be benign tumors, but there are some histological features that make some subgroups suspicious of malignancy. The treatment of these tumors consist in their surgical resection, with no current effective complementary oncological treatment known. We present the clinical case of a woman that underwent surgery for a resection of a hepatic lesion labeled afterwards as a PEComa with malignant features.


Los tumores de células neoplásicas perivasculares epitelioides (PEComas) son una familia de tumoraciones caracterizada apenas un par de décadas antes. Componen un grupo inusual de neoplasias, que puede aparecer en distintas localizaciones del organismo. Por lo general, los PEComas se consideran tumores benignos, pero hay ciertas características histológicas que hacen de algunos subgrupos lesiones sospechosas de una malformación maligna. El tratamiento de estos tumores consiste en la resección quirúrgica, pero no existe tratamiento oncológico por completo eficaz. Se presenta el caso clínico de una mujer sometida a la resección de una lesión hepática con diagnóstico posterior de PEComa con rasgos de proceso maligno.
