890 Possible Causes for Leukocytosis, Petechiae

  • Infectious Mononucleosis

    Sprunt, Frank Alexander Evans (1889-1956): Mononuclear leukocytosis in reaction to acute infection (infectious mononucleosis).[] Conclusions and Relevance In adolescent and adult patients presenting with sore throat, the presence of posterior cervical, inguinal or axillary adenopathy, palatine petechiae[] Leukocytosis is a common feature of infectious mononucleosis and absence of this should suggest an alternative diagnosis.[]

  • Upper Respiratory Infection

    White blood cell count: Leukocytosis is very common with counts more than 10,000 per cubic millimeter and a predominance of polymorphs and immature neutrophils.[] […] nodes ( 1 cm) Absence of conjunctivitis, cough, and rhinorrhea, which are symptoms that may suggest viral illness [2] Less common findings in streptococcal pharyngitis are petechiae[]

  • Streptococcal Infection

    These include: Blood counts: Both leukopenia and leukocytosis have been reported with relatively equal frequencies. A marked left shift of the differential is common.[] Cutaneous petechiae are not uncommon, and a scarlatiniform rash may be present.[] […] regarding clinical characteristics including albumin level, blood pressure, pulse rate, respiration rate, smoking, age, sex, body mass index, hemoglobin, coexisting disease, leukocytosis[]

  • Primary Myelofibrosis

    Abstract Leukocytosis is occasionally seen in patients with presumptive but undiagnosed myeloproliferative disorders (MPD).[] Clinical manifestations depend on the type of blood cell affected and may include anemia, pallor, splenomegaly, hypermetabolic state, petechiae, ecchymosis, bleeding, lymphadenopathy[] Petechiae (flat, red, pinpoint spots under the skin that are caused by bleeding). Fever. Night sweats. Weight loss.[]

  • Henoch-Schönlein Purpura

    Laboratory tests showed leukocytosis, proteinuria, and elevated creatinine. A skin biopsy revealed small-vessel neutrophilic vasculitis.[] PATIENT CONCERNS: A 64-year-old man was admitted to the hospital with petechiae and palpable purpura in lower limbs and abdominal pain for about 1 month.[] Lab findings and studies Elevated serum IgA levels Normochromic anemia May be seen with GI bleeding Markers of inflammation (leukocytosis, ESR) Usually elevated when a bacterial[]

  • Myeloproliferative Disease

    […] a Philadelphia (Ph) chromosome without DNA breakpoints in the M-bcr region; (3) the spontaneous loss of detectable Ph-positive cells, 5 years after the first finding of leukocytosis[] […] of splenic infarction and perisplenitis Clinical symptoms can include the following: Pallor (except in patients with polycythemia vera) Plethora secondary to polycythemia Petechiae[] Mice developed a completely penetrant myeloproliferative syndrome characterized by leukocytosis with normal maturation of myeloid lineage cells; myeloid hyperplasia in bone[]

  • Leukemia

    Evaluation Step 0: Leukocytosis ( White Blood Cell Count 11,000/mm3) Confirmed with a second Complete Blood Count with differential No other obvious cause for Leukocytosis[] "Petechiae usually appears on the lower extremities," Wadleigh adds.[] They usually manifest as abnormal leukocytosis with or without cytopenia in an otherwise asymptomatic person.[]

  • Acute Myelocytic Leukemia

    Thus, the bone marrow and peripheral blood are characterized by leukocytosis with a predominance of immature cells, primarily blasts.[] Thrombocytopenia often causes petechiae on the lower limbs. DIC may aggravate the situation and cause larger lesions.[] Twenty patients (50%) had leukocytosis ( 10,000 WBC/μL) during induction therapy.[]

  • Subacute Bacterial Endocarditis

    Laboratory studies may show anemia, leukocytosis, elevated erythrocyte sedimentation rate (ESR), and microscopic hematuria.[] Abstract SBE manifests many skin findings including petechiae, splinter hemorrhages of the nails, Osler's and laneway lesions, clubbing of the fingers, and findings suggestive[] Laboratory testing may reveal anemia, leukocytosis, elevated ESR, positive rheumatoid factor, hematuria, and red blood cell (RBC) casts in urine.[]

  • Infective Endocarditis

    CASE PRESENTATION: A 57-year-old white man presented with bilateral large leg ulcers, fever, and marked leukocytosis.[] External links [ edit ] Look up petechia in Wiktionary, the free dictionary. Wikimedia Commons has media related to Petechiae .[] […] lesions , A nemia, N ail bed hemorrhage, E mboli References: [15] [6] [17] [18] [19] [20] [21] [22] [23] Diagnostics Laboratory studies Best initial test: blood cultures Leukocytosis[]
