Study Notes
Clinical Features of Herpangina
- Lesions start as erythematous macules but rapidly progress to grey vesicles with erythematous base
- May also appear on trunk, thighs, buttocks, and genitalia
- Lesions are usually asymptomatic but can be itchy or painful
- Mild pyrexia, sore throat, headache, and dysphagia may occur
Hand, Foot, and Mouth Disease
- Caused by Coxsackie virus (usually A16, rarely type 5 and 10)
- Transmitted by droplet infection
- Incubation period: 10-14 days
Lesions and Ulceration
- Ulceration is defined as a break in the continuity of an epithelial lining
- Iron deficiency is a significant etiology in angular cheilitis
- Without denture, it is more likely to be caused by infection with Streptococcus or Staphylococcus species
- Treatment should be commenced with azole's, unless the classic golden crust associated with S. aureus is present
Median Rhomboid Glossitis
- Seen in patients using inhaled steroids and smokers
- Lesions are in the center of the dorsum of the tongue and palate (kissing lesion)
- Lozenge-shaped erythematous patch on the midline dorsal tongue
- H/P epithelial hyperplasia with neutrophils in the parakeratin layer
Vesiculobullous Lesions
- Anagina Bullosa Haemorrhagica: recurrent blood blisters in oral mucosa, most commonly seen in posterior hard and soft palate
- Blisters rupture to leave a superficial ulcer, which is entirely self-limiting
White Lesions
- White lesions are white due to hyperplasia of epithelium and loss of normal vascularity
- Examples include candidosis, hairy leukoplakia, condyloma acuminata, papilloma, and syphilitic leukoplakia
Pigmented Lesions
- Necrotic granulomatous reaction affecting palate or tongue, perforation of palate
- Can be extrinsic or intrinsic
- Extrinsic pigmentation is usually recognized and common causes are regular CHX rinsing
