Systemic mastocytosis with review of gastrointestinal manifestations.
A 63-year-old man presented with fever, splenomegaly, steatorrhea, diarrhea, and weight loss. A tissue diagnosis of systemic mastocytosis was made. This case is unusual in that diarrhea and steatorrhea were present in the absence of skin lesions and because fever was a prominent symptom. Thus, systemic mastocytosis should be included in the differential diagnosis of intestinal malabsorption even when the skin shows no abnormalities. The gastrointestinal manifestations of systemic mastocytosis are reviewed.
