Collagenous, microscopic and lymphocytic colitis. An evolving concept

Virchows Arch. 1994;424(6):573-9. doi: 10.1007/BF00195769.


Collagenous colitis and lymphocytic colitis (previously described as microscopic colitis) are two newly recognised forms of colitis. Both have generated much controversy and continue to do so; their aetiology and pathogenesis are unresolved and their association with a variety of immune-related disorders is intriguing. Response to available therapeutic modalities is often disappointing. The possible relationship or overlap between these two conditions remains a controversial issue. The aim of this review is essentially to present an overview of collagenous colitis and lymphocytic colitis and to propose an unifying concept with an adapted terminology.
