Quiste adrenal endotelial / Adrenal entothelial cyst

Adrenal cysts are rare and form a heterogeneous group of lesions that includes (a) parasitic cysts, (b) epithelial cysts, (c) pseudocysts, and (d) endothelial cysts. There is evidence (immunohistochemical and ultrastructural) that both pseudocysts and endothelial cysts are variants of vascular cysts. Adrenal vascular cysts account for 84% of adrenal cysts. They are more common in women and present clinically with abdominal pain or are incidental findings. Their imaging features are not specific. Grossly, both types of adrenal vascular cysts are encapsulated. Pseudocysts are unilocular, thick-walled, and devoid of endothelial lining, whereas endothelial cysts are thin-walled, multilocular, and lined by endothelium. Adrenal vascular cysts probably originate from a preexisting vascular hamartoma. The treatment of choice is surgical excision. The prognosis is excellent. (Arch Pathol Lab Med. 2006;130:1722–1724)

Patología del trasplante renal / Tipos de rechazo

En esta ocasión hacemos algunos comentarios generales sobre las distintas formas clínicas y patológicas del rechazo al injerto en el trasplante renal. Probablemente un tema poco frecuente en el día a día de la patología quirúrgica, sin embargo debido a su importancia es necesario conocer al menos de forma general el tema. Al final un esquema breve donde se menciona la clasificación de Banff.
