A Case of Cronkhite-Canada Syndrome Showing Spontaneous Remission

ABSTRACT

Cronkhite-Canada syndrome (CCS) is a rare, noninherited gastrointestinal polyposis syndrome associated with ectodermal changes such as alopecia, nail dystrophy, and cutaneous hyperpigmentation. The etiology and pathogenesis of CCS are not known, but diarrhea, malnutrition, gastrointestinal bleeding, and infection may occur in the affected patient; moreover, this condition could be fatal. However, previous reports have described several cases of spontaneous remission. We report a 60-year-old man who was incidentally found to have colonic polyposis, alopecia, and hypogeusia and was diagnosed to have CCS. However, this patient experienced spontaneous remission, including regrowth of body hair and alleviation of bowel inflammation, without any specific medications such as steroids, antibiotics, or proton pump inhibitors.
