An injected throat caused by infective inflammation involving pharyngeal mucous membranes and lymphoid follicles. It is usually self-limiting and recovers naturally or with symptomatic treatment.
Inflamed scattered lymphoid follicles of posterior pharyngeal wall with normal coloured mucosa seen in between in a patient presented with generalized painless lymphadenopathy. Excisional lymph node biopsy confirms lymphoma.
Arrows point to the lymphoid follicles.

Grade II tonsillar hypertrophy with reticular surface appearance.
(T - tonsil, U - uvula)
Tonsillar crypts and clefts predispose to several conditions like peritonsillar abscess, retained food residues, and tonsillolith formations. Halitosis and
unusual tonsillar appearance are the usual presenting symptoms though it can be asymptomatic and found by chance on examination. Oropharyngeal endoscopic assessment, probing with blunt instrument, and digital palpation need to be done. Figure shows cheesy-white materials in the supratonsillar cleft due to food residue/epithelial sloughs entrapment. Beware of the underlying dysplasia/malignancy and if in doubt examination under anaesthesia
with/without excision biopsy (tonsillectomy)
will have to be performed.

Retained material/debris or phlegmon in tonsil crypts (arrows) with unilateral tonsillar enlargement. Underlying tonsillolith (tonsil stone) need to be ruled out.
White keratin on both tonsils surface especially worse at proximity of its crypts and clefts in an otherwise healthy patient. No sorethroat, fever, or swallowing difficulty and no history to suggest recurrent tonsillitis. (U - uvula, T - tonsil, X - incidental finding of small pedunculated papilloma)
Multiple throat ulcers involving the soft palate, uvula, and palatoglossal folds (arrows) which had caused severe sorethroat and painful swallowing.

Thick and confluent fibrin exudates covering both tonsillar beds.
Thick fibrin covering the tonsil bed bilaterally.
Confluent fibrin formed 5 days post-tonsillectomy.
Disappearing fibrin and speeding of re-epithelization
around 1 week post-tonsillectomy.
Fibrinous sloughs formation in the tonsillar bed is a normal phenomena after tonsillectomy. This will be replaced by normal epithelium usually within 1-2 weeks as healing occurs.

Blood clot attached to right tonsil bed in a patient who presented with haematemesis few hours earlier. She had tonsillectomy done 9 days ago. This is the typical features of secondary post-tonsillectomy haemorrhage. Examination under general anaesthesia and haemostasis is indicated. Warning: Do not remove the blood clot in the clinic!!!

Another image of the throat after tonsillectomy. Secondary pharyngeal lymphoid hyperplasia is obvious seen. (+) - site of tonsil pre-removal, U -uvula.
This image shows thick membranous exudate involving both tonsils in acute tonsillitis. Severe odynophagia with poor oral intake warrants hospital admission with intravenous fluid and antibiotics therapy given.
Confluent exudate covering the tonsillar surface in acute exudative tonsillitis.
Infectious mononucleosis need to be considered in such cases. Prominent cervical lymphadenitis is usually present and variable degree of jaundice due to viral-induced hepatitis.

T - tonsil, U - uvula. Note the exudates along tonsillar crypts.
Oedematous uvula in acute tonsillitis. Snoring, if already present can become worse during this time.
Inflamed posterior pharyngeal wall scattered lymphoids in acute tonsillo-pharyngitis.
Parenchymatous tonsillitis showing inflamed and swollen tonsils bilaterally (T) with minimal to absent surface exudates or follicles. The uvula is oedematous and inflamed as well.
Inflamed and enlarged tonsils with minimal exudates at supratonsillar cleft bilaterally
Acute infective inflammation involving the tonsils (T) and posterior pharyngeal wall scattered lymphoid follicles (+). Noted whitish-grey exudates coating the surface of these lymphoid structures. View taken at velopharyngeal level by using distal chip fiberoptic scope.
Greyish-white fibrin exudate covering surfaces of infected tonsils (T), scattered pharyngeal lymphoids (arrows), and the lowermost nasopharyngeal lymphoid (X). [U - uvula]
A unilateral infective inflammation beyond tonsillar capsule which presents with sorethroat, odynophagia (painful swallowing) and fever. Clinically there is fullness or swelling around palatoglossal fold (elipse) and distal ipsilateral soft palate with no obvious exudate seen on tonsillar surface or from its crypts. The uvula remains central but can be odematous. This lesion may lead to peritonsillar abscess if not treated appropriately. Diagnostic aspiration is negative for pus. CT-scan seldom required unless pain worsens with severe odynophagia (even to swallowing own saliva), presence of trismus with limited mouth opening, or unsettled fever. These symptoms are highly suggestive of peritonsillar abcess formation which will needs a proper incision and drainage procedure to be done.
Indurated soft palate crossing midline in established of left-sided peritonsillitis (red outline). The uvula is inflamed and swollen (+). (white line - midline)
Peritonsillar abscess is a collection of pus beyond the capsule of the tonsil. Clinically, mucosal inflammation with swelling will be noted and the tonsils itself is pushed medially and the uvula can be seen off midline to the opposite site. Figure shows left peritonsillar abscess and the red dot point to the drainage spot for diagnostic aspiration/drainage.
