Tsutsugamushi disease is an acute infectious disease caused by Rickettsia tsutsugamushi.The clinical symptoms of tsutsugamushi disease are varied and non-specific,such as sudden onset fever with chills,rash,skin eschar of ulcer,lymphadenectasis,et al.Patients could combine with multi-organ dysfunction,include respiratory failure,heart failure,mild renal or hepatic dysfunction,circulatory shock or hematological abnormalities.Since the symptoms and signs are non-specific and resemble other tropical infections like malaria,enteric fever,dengue or leptospirosis,appropriate laboratory tests are necessary to confirm diagnosis,and reduce misdiagnosis and missed diagnosis rate.The mainstay of treatment is the tetracycline,chloramphenicol,macrolide and quinolone group of antibiotics.In mild cases,recovery is complete.In severe cases with multi-organ failure,mortality may be as high as 24％.Improve the early diagnosis and timely treatment of the disease,for improving the prognosis of patients,reduce the disease burden is of great significance.

ObjectiveTo analyze the clinicopathologic features of hereditary cutaneomucosal venous malformation (VMCM) in a Chinese family.MethodsFamily history was investigated in a family with VMCM,and tissue specimens were obtained from the lesions of the proband and subjected to histopathological analysis.ResultsAmong 65 members from 5 generations of the family,19 were affected by VMCM,hinting an autosomal dominant inheritance.None of the family members experienced gastrointestinal bleeding,central nervous system disorders,or cardiac defects.Affected individuals usually presented with multiple irregularly sized,blue-violet,elevated and slightly indurated masses located in the oral mucosa and subcutaneous tissue of the extremities.Pathological analysis showed malformed veins with abnormally dilated cavities and irregularly thickened walls.Although small veins were abnormally proliferating and clustered,there was no endothelial discontinuity.The smooth muscle layer was thickned in a varying degree or absent.ConclusionA diagnosis of VMCM is made according to the inheritance manner,clinical manifestation and pathological findings.
