Large Intra-Abdominal Desmoid Tumor in a Deployed Soldier Initially Presented With Chronic Diarrhea

Abstract

Diarrhea is a common condition seen among soldiers in both garrison and deployed environments. Although the vast majority of soldiers with diarrhea will recover uneventfully with supportive care, clinicians should also maintain suspicion for less common causes and perform a thorough physical exam. We report the case of a young, healthy soldier with chronic diarrhea and progressively worsening abdominal distention that began during his deployment to Honduras who was subsequently found to have a large intra-abdominal desmoid tumor. Desmoid tumor is a rare and benign neoplasm that typically appears on the extremity, abdominal wall, intra-abdominal space, and occasionally in the chest wall. This tumor may be associated with abdominal distension and gastrointestinal complaints. A large tumor can compress organs, causing local tissue damage and, in rare cases, death.
