Las numerosas comunicaciones sobre cuadros diarreicos, sangrados y perforaciones en tubo digestivo ocasionados probablemente por citomegalovirus en pacientes adultos homosexuales, plantean la posibilidad de la infeccion directa de la mucosa intestinal por el virus citomegalico contenido en el liquido seminal. En la edad pediatrica se encontraron trece casos con cuadros de diarrea prolongada, en ocasiones con sangre en las evacuaciones provocados por ulceraciones muy similares a las descritas en el adulto; el proceso de vasculitis que acompano a las lesiones mostro las celulas caracteristicas de la infeccion por citomegalovirus. Se establecio asi la posibilidad de infeccion directa de las celulas del tracto gastrointestinal por las particulas virales contenidas en la leche materna con posible diseminacion posteriormente a otros organos

Se informan las caracteristicas clinopatologicas de cinco pacientes con hamartoma mesenquimatoso hepatico, estudiados en los Servicios de Cirugia y Patologia del Hospital de Pediatria del Centro Medico Nacional del IMSS. Esta entidad se presento generalmente en los dos primeros anos de la vida y clinicamente se manifesto por crecimiento del hemiabdomen superior. Los estudios radiograficos fundamentales para establecer el diagnostico fueron la arteriografia y ecosonografia. El tratamiento fue quirurgico con buena evolucion. Hasta 1980 se han comunicado 30 casos en la literatura mundial/

The clinical and anatomicopathological characteristics of acute and chronic toxoplasmosis are described as they affect different structures and systems. The lesion to adrenal glands is compared to that seen in disseminated herpes simplex; however, the question remains as to why in both congenital infections, necrosis of adrenal glands appears without inflammatory reaction. The investigation of special techniques for localization and identification of Toxoplasma gondii "groups" or cysts, leads to the conclusion that Grocott's silver impregnation technique used for the identification of Entamoeba histolytica is also useful to discover Toxoplasma in tissues.

Judged by the cases studied at the Hospital de Pediatría, congenital toxoplasmosis may be transmitted to several descendants and the infection capacity of the mother persists for a long time. The possibility of toxoplasma infection should be investigated in cases of hydrocephalus, convulsions, microcephalia, ocular lesions or pictures of neonatal hepatitis. To explain invasion to the central nervous system by Toxoplasma gondii, a pathogenic hypothesis is offered.
