ABSTRACT
Los angioqueratomas son lesiones vasculares relativamente infrecuentes que consisten en pápulas hiperqueratósicas rojo-violáceas. Éstas pueden ser únicas o múltiples, estar localizadas en un único segmento corporal o ser generalizadas y estar o no asociadas a otras enfermedades subyacentes. El presente trabajo abordará en profundidad los angioqueratomas generalizados complementando la primera parte en la que se trataron los angioqueratomas localizados.
Angiokeratomas are a relatively non-frequent group of vascular lesions that consist on hyperkeratotic red-violaceous papules. Lesions can be solitary or multiple, localized or generalized and may be associated or not with a systemic disease. The present work is a throughout review on generalized angiokeratomas and it is a complement of the first part in which localized angiokeratomas have been discussed.

Descrevem-se os achados clínicos e patológicos da intoxicação experimental por Sida carpinifolia em bovinos. Para a reprodução experimental da doença, folhas verdes da planta foram coletadas semanalmente na região do Alto Vale do Itajaí e fornecidas in natura diariamente para cinco bovinos nas doses de 10 e 20g/kg por 120 dias, 40g/kg por 30 dias, e 30 e 40g/kg de peso animal por 150 dias. Um bovino morreu e os outros foram eutanasiados ao final do período de consumo da planta. Os principais sinais clínicos consistiam de andar em marcha, olhar atento e tremores de cabeça e foram de intensidade leve a acentuado conforme a dose de planta e tempo de consumo. A lesão histológica predominante caracterizava-se por vacuolização e tumefação de neurônios (principalmente os de Purkinje), das células acinares pancreáticas e células foliculares da tireóide. Ultra-estruturalmente verificou-se vacúolos, por vezes, contendo material finamente granular em neurônios, células acinares pancreáticas e células foliculares da tireóide. S. carpinifolia causa doença de depósito lisossomal em bovinos quando consumida por período prolongado, mesmo em pequenas doses.
Clinical and pathological findings of experimental poisoning by Sida carpinifolia in cattle are described. A neurologic disease was observed in cattle on farms of the Alto Vale do Itajaí region of the Brazilian state of Santa Catarina. For the experimental reproduction of the disease, fresh green leaves, weekly harvested in the same region where spontaneous case occurred, were force-fed to five cattle at doses of 10 and 20g/kg for 120 days, 40g/kg for 30 days, and 30 and 40g/kg body weight for 150 days. One animal died and the others were euthanatized at the end of the experiment. Clinical signs and lesions varied from mild to severe in the experimentally poisoned cattle and depended on dose and length of the period of consumption. Main histological and ultrastructural lesions consisted of vacuolation and distension of neuronal perikarya (mainly of Purkinje cells), and of the cytoplasm of acinar pancreatic cells and thyroid follicular cells. It is concluded that ingestion of even small amounts S. carpinifolia for prolonged periods of time cause lisosomal storage disease in cattle.

The term dysostosis multiplex is specifically applied to the group of radiological features collectively found in a number of specific metabolic disorders including the mucopolysaccharidoses, mucolipidosis, mannosidosis, fucosidosis and several other rarer conditions. We report eight cases of mannosidosis, fucosidosis and mucolipidosis with special emphasis on the differentiation from the more common mucopolysaccharidoses.
