Pharyngitis: Or something else? Differential Diagnosis

Respiratory System (J00-J99)

  • Pharyngitis chronica hyperplastica (granulosa) (Pharyngitis granulosa) – Form of chronic pharyngitis associated with hyperplasia of the lymphoid follicles; the lymphoid follicles of the posterior pharyngeal wall are enlarged and the patient experiences a foreign body sensation in the throat as well as retching and clearing of the throat.
  • Pharyngitis lateralis – form of chronic pharyngitis associated with hyperplasia of the lymphoid tissue of the lymphoid lateral cords of the pharynx.
  • Pharyngitis sicca – form of chronic pharyngitis with dehydration of the mucous membrane; people who are constantly exposed to dehydrating noxious substances, such as smokers and road workers show increased complaints
  • Tonsillitis (tonsillitis)

Blood, blood-forming organs – immune system (D50-D90).

  • Plummer-Vinson syndrome – disease that leads to difficulty swallowing burning tongue due to atrophy of the mucous membrane in the mouth, the following also occur: mucosal defects, rhagades of the corner of the mouth (tears in the corner of the mouth), brittle nails and hair and dysphagia (difficulty swallowing) due to larger mucosal defects; the disease is a risk factor for the development of esophageal cancer (esophageal cancer).

Endocrine, nutritional, and metabolic diseases (E00-E90).

  • Diabetes mellitus

Skin and subcutaneous tissue (L00-L99)

  • Pemphigus – skin disease belonging to the group of blistering autoimmune dermatoses.

Infectious and parasitic diseases (A00-B99).

  • Botulism – disease caused by poisoning with botulinus toxin (bacterial toxin).
  • Malleus humidus (nasal snot) – disease caused by the bacterium Burkholderia mallei, usually affecting equines such as horses or donkeys, occasionally camels, but rarely dogs and cats. Humans can also contract glanders (= melioidosis); transmission: Inhalation or via contaminated drinking water; life-threatening bacteremia may occur – typically after an ascending infection; course: Bacteria infect liver, spleen, skeletal muscle or prostate; antibiotic therapy usually comes too late; mortality (death rate) in sepsis up to 80%; risk groups: Diabetics, immunocompromised patients.
  • Anthrax – notifiable bacterial infectious disease with the rod-shaped bacterium Bacillus anthracis, which mainly affects animals (pigs, cattle, horses, sheep and goats) and which mainly affects professional groups working with animals; furthermore, there is the so-called injection anthrax in i.v. drug users through the injection of heroin contaminated with anthrax spores.
  • Mononucleosis (synonyms: Pfeiffersches glandular fever, infectious mononucleosis, mononucleosis infectiosa, monocytenangina or kissing disease, (Student́s) kissing disease, called) – common viral disease caused by the Epstein-Barr virus (EBV); this affects lymph nodes, but can also affect the liver, spleen and heart.
  • Tetanus (tetanus)

Liver, gallbladder, and bile ducts – Pancreas (pancreas) (K70-K77; K80-K87).

  • Liver damage, unspecified

Musculoskeletal system and connective tissue (M00-M99).

  • Sjögren’s syndrome (group of sicca syndromes) – autoimmune disease from the group of collagenoses, resulting in a chronic inflammatory disease of the exocrine glands, most commonly the salivary and lacrimal glands; typical sequelae or complications of sicca syndrome are:
    • Keratoconjunctivitis sicca (dry eye syndrome) due to lack of wetting of the cornea and conjunctiva with tear fluid.
    • Increased susceptibility to caries due to xerostomia (dry mouth) due to reduced salivary secretion.
    • Rhinitis sicca (dry nasal mucous membranes), hoarseness and chronic cough irritation and impaired sexual function due to disruption of mucous gland production of the respiratory tract and genital organs.
  • Scleroderma – group of various rare diseases associated with hardening of connective tissue of the skin alone or the skin and internal organs (especially digestive tract, lungs, heart and kidneys).

Psyche – nervous system (F00-F99; G00-G99).

  • Paresis (paralysis) of the glossopharyngeal nerve (tongue-gullet nerve) or the vagus nerve (major nerve of the autonomic nervous system)
  • Mental disorders, unspecified

Symptoms and abnormal clinical and laboratory findings not elsewhere classified (R00-R99)

  • Uremia (occurrence of urinary substances in the blood above normal levels).

Medication

Environmental pollution – intoxications (poisoning).

  • Arsenic poisoning
