ABSTRACT
Se presenta el caso de una paciente de 43 anos de edad en la que se descubrio hipertension arterial pulmonar. Desde el punto de vista clinico, de laboratorio y de gabinete, hemodinamico y estudio histopatologico fue catalogado como "primaria", por no haberse encontrado causa que justificara su etiologia. Se lleva a cabo una revision de la literatura sobre dicha entidad nosologica, pudiendose afirmar que este caso es el tercero reportado en nuestro pais. Se hacen consideraciones sobre la etiologia y aspectos histopatologicos, enfantizando que en forma practica cualquier paciente con hipertension arterial pulmonar "grave", obliga a tener en la mente a la hipertension arterial pulmonar primari

Twenty-one autopsy protocols (1967-77) of children with the pathological diagnosis of thrombosis of renal vein were included in this study. Sixteen cases were bilateral and the remaining 5 were affected in one side. No correlation was found between pre and perinatal background to support the diagnosis. All facts showed electrolytic unbalance and severe metabolic acidosis. The coagulation tests showed unspecific disturbances. In six cases, it was possible to make pathological confirmation of disseminated intravascular coagulation. The classic triad of abdominal tumor, hematuria and uremia were found in a low percentage.

A newborn baby with bilateral renal vein thrombosis is presented; diagnosis was made on clinical and radiological basis; she died with severe complications such as pulmonary hemorrhage and disseminated intravascular coagulation. It is emphasized that the bilateral form is rare and prognosis is variable depending upon clinical evolution.

Hyper-pigmentation as a manifestation of contact sensitivity to optical brighteners has previously been reported. In 1973 we observed an epidemic of pigmented contact dermatitis occurring in a textile mill in connection with the manufacture of drill fabrics impregnated with a recently introduced azo dye coupling component Naphthol AS. Of the 53 workers included in the study, 12 presented a spotted pattern of hyperpigmentation mainly affecting the exposed areas, but without pruritus, 18 were pigmented to a lesser degree, and in 21 it was not possible to discern any well-defined discoloration; some of the patients in the last group, however, complained of slight pruritus. The last two patients who were fair-skinned showed a reddish-brown pigmentation and a well pronounced pruritus. Hyper-pigmentation was most pronounced in individuals with dark complexions, whereas fair-skinned patient also showed "classical" eczematous symptoms including pruritus. A field study demonstrated direct exposure to the chemical. All 53 patients were patch-tested with Naphthol AS 5% in water, and 24 were found to be positive. Histological features were melanocyte proliferation, incontinence of pigment, and various degrees of damage to the basal layer.
