Anti–Hu-Mediated Paraneoplastic Chronic Intestinal Pseudo-Obstruction Arising From Small Cell Prostate Cancer

: Chronic intestinal pseudo-obstruction is a rare syndrome with high morbidity and mortality. The pathophysiology is not well understood, although it is postulated that it involves some sort of neuropathic and/or myopathic dysfunction resulting in intestinal dysmotility. We present the first case of chronic intestinal pseudo-obstruction secondary to a paraneoplastic syndrome associated with a primary small cell prostate cancer.
