ABSTRACT

Background: Rocky Mountain spotted fever (RMSF) is a potentially fatal zoonotic disease caused by Rickettsia rickettsii, which is primarily transmitted by tick bites. The clinical features may include, in addition to skin manifestations, gastrointestinal symptoms, such as nausea or vomiting, diarrhea and abdominal pain that can be confused with appendicitis. Delays in diagnosis and treatment may cause serious complications and death. On the other hand, the appendiceal ectasia consists dilated cecal appendix with the accumulation of mucinous material, usually being an incidental surgical finding. Its clinical presentation can also simulate various infectious and surgical abdominal conditions such as appendicitis. Case report: This is a six years old school girl patient who was diagnosed with both diseases during the same period of time. Initially, she had symptoms and signs that suggested either an acute respiratory or a gastrointestinal infectious disease were the main complain. Days later she began with symptoms compatible with acute appendicitis that required appendectomy. The diagnosis of appendiceal ectasia was established by histopathologic study, while the RMSF was confirmed by indirect immunofluorescence. Conclusions: In the presence of a febrile rash illness, we have to consider the diagnosis of RMSF. This case is unique because the association of appendiceal ectasia and RSMF.
