Sample QuestionA 7 year old child presents with hypoalbuminemia, edema, hyperlipidemia, and proteinuria. The edema is in the periorbital region initially and eventually spreads to the rest of the body. The patient is given steroid therapy and the disease goes away. What is a key morphological feature of the patients disease?
