Menetrier's disease: report of a transient case associated with chylous ascites.

We present a case of transient Menetrier's disease (MD) that was associated with chylous ascites. Using immunohistochemistry, we studied the expression of transforming growth factor alpha in this patient's gastric mucosa biopsy over time; a growth factor that has previously been shown to play an active role in the pathogenesis of MD. Excessive expression and altered localization of transforming growth factor alpha was observed while the patient had active disease with return to the normal pattern after resolution of the disease. This case is the first one reported of transient MD associated with chylous ascites; it lends further credible evidence to the concept that altered transforming growth factor alpha expression may play an important role in the pathogenesis of MD.
