40 Possible Causes for Petechiae of the Buccal Mucosa

Show results in: Italiano

  • Endocarditis

    He is lethargic and has petechiae on the buccal mucosa and extremities. He is admitted to the hospital for evaluation and treatment of sepsis of unknown origin.[]

  • Subacute Bacterial Endocarditis

    A case of subacute bacterial endocarditis due to Actinobacillus actinomycetemcomitans is reported. The patient was successfully treated first by a combination of gentamicin and ampicillin and then, because of severe allergic reactions, ampicillin was replaced by co-trimoxazole; symptoms did not recur and blood[…][]

  • Triazolam

    Moderate to severe petechiae were present on his conjunctivae, buccal mucosa, and laryngeal mucosa at autopsy. Cardiac chambers contained a normal volume of fluid blood.[]

  • Autoimmune Thrombocytopenia

    A 70-year-old woman was admitted with rectal bleeding accompanied by widespread petechiae, bruising, tongue and buccal mucosa bleeding, and epistaxes and proved refractory[]

  • Bacterial Endocarditis

    Acute coronary syndromes in the setting of infective endocarditis may be the result of coronary compression secondary to periannular aortic valve complications, coronary embolism, obstruction of the coronary ostium due to a large vegetation, coronary atherosclerosis, and severe aortic insufficiency. External[…][]

  • Candidal Endocarditis

    Candidal endocarditis can develop if candidemia occurs during Swan-Ganz catheterization. Candida endocarditis may persist for many months and is fatal unless the infected valve is resected. Herein is reported the first case of rupture of a mycotic pulmonary artery aneurysm caused by chronic candidal endocarditis.[…][]

  • Infective Endocarditis

    Acute acalculous cholecystitis (AAC) is a necroinflammatory disease of the gallbladder with no gallstones present. ACC is known to be a serious, even potentially lethal complication observed mainly in patients with various severe underlying conditions including trauma, burn and sepsis. Infection of cardiac implantable[…][]

  • Acute Bacterial Endocarditis

    Acute bacterial endocarditis (ABE) is most commonly due to virulent pathogens, i.e., Staphylococcus aureus. S. aureus ABE may be due to methicillin-sensitive (MSSA) or methicillin-resistant (MRSA) strains and, optimally, ABE should be treated with bactericidal antibiotics. Traditionally, vancomycin has long been used to[…][]

  • Traumatic Asphyxia

    Where the vessels are not supported by the surrounding tissue, as in the conjunctival and buccal mucosa, or when the retrograde pressure is excessive, there is actual extravasation[] […] of erythrocytes from the vessels, with production of petechiae and ecchymoses [ 2 , 5 ].[] […] increasing the intrathoracic pressure, and this sudden marked increase in pressure in the small veins and capillaries causes rapid dilatation and minute hemorrhages, resulting in petechiae[]

  • Thrombocytopenia

    One day after the patient's illness resolved, petechiae and bloody ulcers developed on his tongue and buccal mucosa ( Supplementary Figure 2 ).[] Physical examination findings were unremarkable, except for a blood pressure of 159/98 mm Hg and generalized petechiae.[]
