Whipple's disease: the great masquerader-a high level of suspicion is the key to diagnosis.

Background: Whipple's disease is a chronic infectious disease that primarily affects the small intestine, but several organs can simultaneously be involved. The disease is caused by a gram-positive bacterium called Tropheryma whipplei. The disease is difficult to suspect because it is rare with unspecific and long-term symptoms; it can be lethal if not properly treated.

[Argon plasma coagulation effective treatment of solitary rectal ulcer syndrome].

Solitary rectal ulcer syndrome (SRUS) is a rare disorder likely to be caused by a traumatic and ischemic mucosal injury related to latent or overt rectal prolapse. Mucosal damage can vary between erythema and up to intractable ulceration. The typical symptoms of SRUS may resemble those of inflammatory bowel disease (IBD)-related proctitis or rectal malignancy with mucus- and blood-mixed defecation with urgency and sometimes transient incontinence.

[Whipple's disease: very rare, fatal without treatment but easily cured].

Whipple's disease is a chronic infectious disease that primarily affects the small intestine, but several organs can be involved simultaneously. The disease is caused by a gram-positive bacterium called Tropheryma whipplei. The disease is difficult to suspect because it is rare, and produces unspecific and long-term symptoms.

A case of fatal cutaneous caput medusae hemorrhage.

Alcoholic liver cirrhosis leads to portal venous hypertension, which can result in a caput medusae formation. Life-threatening hemorrhage from a ruptured caput medusae vein is a rare complication. It is crucial to stop the bleeding promptly.

A case of extreme weight loss due to mesenteric ischemia and antiphospholipid syndrome.

Mesenteric ischemia and antiphospholipid syndrome is a rare combination but should be suspected as a differential diagnosis. This may be presented as diffuse abdominal pain typically after food intake, diarrhea, and weight loss. Early recognition is warranted, and nutrition, stenting, and anticoagulant treatments are indicated.
