The Use of Deep Snare Biopsies to Diagnose Cronkhite-Canada Syndrome.

Cronkhite-Canada syndrome is a rare sporadic polyposis syndrome that presents with dermatologic and neurologic symptoms in addition to nutritional deficiencies. It can mimic alternate pathologies, such as Menetrier disease, making adequate histologic sampling with deep snare biopsies necessary for tissue comparison. We present a case report of Cronkhite-Canada syndrome that demonstrates the importance of deep tissue sampling for adequate diagnosis and treatment initiation.
