Also known as: Toxic adenoma
Benjamin has a thyroid nodule producing excess hormone, causing extreme altruism, arrhythmia, muscle tremors, and collapse. House deliberately worsens his condition with iodine contrast to confirm the diagnosis. Treatment involves surgical removal of the nodule.
Also known as: Kidney failure
A patient in Foreman's care has end-stage renal disease and needs a kidney transplant urgently. Benjamin initially agrees to donate his kidney to her, creating ethical conflict when House suspects Benjamin's generosity is a symptom of illness. The patient dies before receiving the transplant.
Also known as: PKD
Another patient approaches Benjamin seeking a kidney donation, claiming to have polycystic kidney disease and limited time. Benjamin's offer to donate both kidneys (to her and the other patient) further demonstrates his pathological altruism as a symptom.
Also known as: Poison ivy
A brief clinic case where House diagnoses a child with a rash on his palms as contact dermatitis from exposure to lotion containing Summer Lilac through contact with someone at a neighbor's pool.
