Introduction:
Whipple's disease is a rare, chronic, systemic disease caused by the actinomycete Tropheryma whipplei. Clinical manifestations vary widely depending on the affected system, the most common being the digestive tract.
Case Presentation:
The authors report the case of a 52-year-old man with malabsorption syndrome, diarrhea, marked weight loss, melanoderma, and visual and proprioception disorders. Periodic acid-Schiff staining of a proximal small bowel biopsy and peripheral-blood PCR identification of T. whipplei confirmed the disease. The patient was initially treated with intravenous ceftriaxone, followed by oral trimethoprim/sulfamethoxazole with significant clinical improvement.
Conclusions:
This case is reported due to its rarity and the diagnostic challenge it presents. Although uncommon, Whipple's disease should be considered as a differential diagnosis of malabsorption syndrome due to its systemic impact and possible treatment with targeted antibiotic therapy.

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
