A case of the hiccups in the setting of colonic ulcers

An Unusual Hiccup: Severe Singultus as a Symptom in Ulcerative Colitis

Inflammatory bowel disease encompasses a group of chronic inflammatory conditions associated with both intestinal and extraintestinal manifestations. We present a 26-year-old man with a history of ulcerative colitis who presented with a disease exacerbation associated with severe intractable hiccups. We report a unique clinical symptom associated with severe ulcerative colitis and the diagnostic dilemma associated with this presentation. This case highlights the importance of recognizing unusual symptoms that can be associated with inflammatory bowel disease exacerbations and demonstrates the therapeutic potential of effective therapy of the underlying inflammatory disease.

Histologic features of colonic infections

Background

The histopathologic diagnosis of infectious colitis remains relevant despite recent advances in microbiologic techniques.

Objective

This article aims to describe the histologic features of selected infectious diseases of the colon.

Materials and methods

Existing reports on histopathologic and clinical aspects of colonic infectious agents were reviewed.

Results

While histology alone may not be as sensitive as current microbiologic methods, tissue identification of infectious agents still plays an important role in patient care. Infectious colitis can have a variety of clinical manifestations, ranging from strongyloidiasis, which can cause a smoldering, subclinical infection for decades, to syphilis, which can clinically mimic cancer or inflammatory bowel disease. Therefore, the histopathologic identification of infection as the cause of a patient’s colitis has a considerable impact on treatment decisions. Morphologic overlap can occur between infection and other diseases, however. Moreover, some infections can elicit various tissue responses beyond acute colitis. Immunosuppressed patients may not mount an inflammatory response to pathogens such as cytomegalovirus or adenovirus. Sexually transmitted proctocolitis can cause plasma-cell-rich inflammation. Gastrointestinal histoplasmosis is more likely to cause diffuse histiocyte infiltration rather than the expected granuloma formation. In some cases, ancillary tests are useful, but equivocal results can cause diagnostic dilemmas.

Conclusion

Given the range with which colonic infectious disorders can manifest, pathologists should be aware of the typical features of infectious colitis, as well as findings beyond the classic morphologies.
