Overview
Pharyngitis should be differentiated from other infectious causes which mimic sore throat that includes oral thrush, infectious mononucleosis, epiglottitis and peritonsilar abscess.[1]
Differentiating Pharyngitis from other Diseases
The major goal of the differentiating patients with sore throat or acute pharyngitis is to exclude potentially dangerous causes (e.g. Group A streptococcus), to identify any treatable causes, and to improve symptoms. Identifying the treatable causes is important because timely treatment with antibiotics helps prevent complications such as acute rheumatic fever, post streptococcal glomerulonephritis.[2]
Thrush | Mononucleosis | Epiglottitis | Peritonsillar abscess |
---|---|---|---|
|

|
|
Variable | Pharyngitis | Oral thrush | Mononucleosis | Epiglottitis | Tonsilitis | Retropharyngeal abscess |
---|---|---|---|---|---|---|
Presentation |
|
Dysphagia without odynophagia which will differentiate it from pharyngitis. | Usually presents with a classic triad of
|
Usually present with stridor and drooling; and other symptoms include difficulty breathing, fever, chills, difficulty swallowing, hoarseness of voice | Sore throat, pain on swallowing, fever, headache, cough | Neck pain, stiff neck, torticollis |
Causes | Group A beta-hemolytic streptococcus. | candidal infection | Epstein-Barr virus | H. influenza type b, beta-hemolytic streptococci, Staphylococcus aureus, fungi and viruses. | Most common cause is viral including adenovirus, rhinovirus, influenza, coronavirus, and respiratory syncytial virus. Second most common causes are bacterial; Group A streptococcal bacteria,[5] | Polymicrobial infection. Mostly; Streptococcus pyogenes, Staphylococcus aureus and respiratory anaerobes (e.g. Fusobacteria, Prevotella, and Veillonella species)[3][4][5][6][7][8] |
Physical exams findings | Inflammed pharynx with or without exudate | White plaques that reveal an erythematous base when scraped | Diffuse lymphadenopathy, particularly bilateral and posterior cervical,Splenomegaly in 50% of cases, Hepatomegaly in 10% of cases, Pharyngeal petechiae, Rash in 90% of patients will develop a pruritic, maculopapular rash after the use of ampicillin or amoxicillin | Cyanosis, Cervicallymphadenopathy, Inflammed epiglottis | Fever, especially 100°F or higher.Erythema, edema and Exudate of the tonsils.cervical lymphadenopathy, Dysphonia.[9][10][11][12] | Child may be unable to open the mouth widely. May have enlarged
cervical lymph nodes and neck mass. |
Age commonly affected | Mostly in children and young adults,
with 50% of cases identified between the ages of 5 to 24 years.[13] |
Usually in immunocompromised patients, including those with advanced HIV/AIDS | Common in adolescents between 15-25 | Used to be mostly found in
pediatric age group between 3 to 5 years, however, recent trend favors adults as most commonly affected individuals with a mean age of 44.94 years.[14] |
Primarily affects children
between 5 and 15 years old.[15] |
Mostly between 2-4 years, but can occur in other age groups.[16][17] |
Imaging finding | — | — | — | Thumbprint sign on neck x-ray | Intraoral or transcutaneous USG may show an abscess making CT scan unnecessary.[18][19][20] | On CT scan, a mass impinging on the posterior pharyngeal wall with rim enhancement is seen.[21][22] |
Treatment | Antimicrobial therapy mainly penicillin-based and analgesics. | oral fluconazole | Supportive therapy
Glucocorticoids may be indicated in such cases of severe airway obstruction. |
Airway maintenance, parenteral Cefotaxime or Ceftriaxone in combination with Vancomycin. Adjuvant therapy includes corticosteroids and racemic Epinephrine.[23][24] | Antimicrobial therapy mainly penicillin-based and analgesics with tonsilectomy in selected cases. | Immediate surgical drainage and antimicrobial therapy. emperic therapy involves; ampicillin-sulbactam or clindamycin. |
