“…Although the histogenetic origin of adenomatoid tumors is highly debated, recognition of these tumors in genital or extra genital sites is important to prevent diagnostic confusion with other neoplasms, especially metastatic adenocarcinoma. Histopathologic features of adenomatoid tumors and adenocarcinoma are well-recognized and differential diagnosis is usually not complicated [7]. But sometimes diffuse, infiltrative growth pattern, extensive coagulation necrosis and cells with small intracytoplasmic vacuoles may cause a diagnostic dilemma and this diagnostic difficulty has led to inappropriate surgery in some of the cases [8].…”

Genital origin adenocarcinomas with coexisting uterine adenomatoid tumors are very rare with only four published cases in the literature. We report a case of adenomatoid tumor of the uterus that was found incidentally during treatment of cervical adenocarcinoma. Although adenomatoid tumors may cause a differential diagnostic problem, in our case the hematoxylin-eosin histological and immunhistochemical studies confirmed mesothelial phenotype of tumor and these also helped in differentiating an adenomatoid tumor from the carcinomatous myometrial invasion. Adenomatoid tumors are easily recognizable benign pathologies. An incidental finding of adenomatoid tumors accompanied by adenocarcinoma of the endometrium or cervix should always be considered.

“…It has been reported to occur in a varity of extragenital sites including the heart, intestinal mesentry, pleura, peritoneum and adrenal gland 1 . The tumors may be present in upto 1% of hysterectomy specimens 2 . CT and MR findings of these tumors simulate the findings of uterine leiomyoma and preoperative diagnosis is difficult 3 .…”

“…En nuestra serie sólo 1 caso se presentó como difuso. Este patrón puede simular un adenocarcinoma (25). Menos frecuente aún, se han descrito algunos casos de presentación de TA en forma simultánea en diferentes órganos, como útero, ovario y apéndice o útero y ovario (14,26).…”

RESUMENAntecedentes: Los tumores adenomatoides (TA) son poco frecuentes. Se encuentran principalmente en el aparato reproductor femenino y especialmente en el útero. No existen reportes a nivel nacional sobre estos. Objetivos: Describir las características histológicas e inmunohistoquímicas de los TA uterinos. Método: Estudio descriptivo de 32 muestras ingresadas al Servicio de Anatomía Patológica de Clínica Las Condes. Las muestras estudiadas fueron recopiladas entre noviembre de 1999 y noviembre de 2008. Resultados: El diagnóstico de TA fue realizado en 21 histerectomías y 11 miomectomías. En 14 casos se diagnosticaron como lesiones nodulares únicas (43,8%) y en 18 junto a leiomiomas (56,2%). El tamaño promedio de las lesiones únicas fue 2,6 cm, significativamente mayor que aquellas asociadas a leiomiomas. El patrón histológico predominante más frecuente correspondió al tipo angiomatoide (81,3%), seguido por los patrones adenoide (9,4%), sólido (6,3%) y mixto (3%), no se encontraron TA quísticos. El estudio inmunohistoquími-co fue positivo en el 100% de los casos para citoqueratina AE1/AE3, calrretinina, vimentina y D2-40. Fue negativo para CD31 y CEA. Sólo un 6,3% (2 casos) fue positivo para citoqueratina 5/6. Conclusiones: Los TA corresponden a tumores benignos de origen mesotelial. Generalmente su diagnóstico es un hallazgo. Al presentarse en el útero, se confunden generalmente con leiomiomas o se presentan en conjunto con estos. En base a lo anterior el tratamiento de estas lesiones debe ser conservador, bastando con la resección del tumor.PALABRAS CLAVE: Tumor adenomatoide uterino, tumor benigno uterino, inmunohistoquímica, tumor mesotelial SUMMARY Background:The adenomatoid tumors (AT) are rare.

The predominant histologic type most often correspond to angiomatoid (81.3%), followed by adenoid patterns (9.4%), solid (6.3%) and mixed (3%), the cystic pattern was not observed. The
