'''Collagenous gastritis''' is an extremely rare pathology of the [[stomach]]. It is seen in children and adults. | |||
===General=== | |||
*Very rare ~ 30 cases reported in total in 2009.<ref name=pmid19730387>{{Cite journal | last1 = Brain | first1 = O. | last2 = Rajaguru | first2 = C. | last3 = Warren | first3 = B. | last4 = Booth | first4 = J. | last5 = Travis | first5 = S. | title = Collagenous gastritis: reports and systematic review. | journal = Eur J Gastroenterol Hepatol | volume = 21 | issue = 12 | pages = 1419-24 | month = Dec | year = 2009 | doi = 10.1097/MEG.0b013e32832770fa | PMID = 19730387 }}</ref><ref name=pmid23363075>{{Cite journal | last1 = Jin | first1 = X. | last2 = Koike | first2 = T. | last3 = Chiba | first3 = T. | last4 = Kondo | first4 = Y. | last5 = Ara | first5 = N. | last6 = Uno | first6 = K. | last7 = Asano | first7 = N. | last8 = Iijima | first8 = K. | last9 = Imatani | first9 = A. | title = Collagenous gastritis. | journal = Dig Endosc | volume = 25 | issue = 5 | pages = 547-9 | month = Sep | year = 2013 | doi = 10.1111/j.1443-1661.2012.01391.x | PMID = 23363075 }}</ref> | |||
====Clinical==== | |||
children:<ref name=pmid23538318> </ref> | |||
*Dyspepsia or anemia. | |||
*Chronic. | |||
Adults:<ref name=pmid19730387/> | |||
*Loose stools. | |||
*Associated with ''[[celiac sprue]]'' or ''[[collagenous colitis]]''. | |||
===Gross=== | |||
*Discolored depression - focal.<ref name=pmid23363075/> | |||
===Microscopic=== | |||
Features: | |||
*Band of eosinophilic material (collagen) expands superficial lamina propria.<ref name=pmid23363075/> | |||
**Band of collagen must be as thick as RBC diameter. | |||
