what do you do now

A

oral rinse to determine fungal
consider nutritional deficiency, HIV, inflammatory

Q

what oral lesions are strongly associated with HIV and why

A

acute necrotising ulceration, kaposi sarcoma, oral hairy leukoplakia, aphthous-ulcers, candidiasis

increased susceptibility to infections due to weakened immune system

Q

discuss pathophysiology of recurrent herpes simplex

A

primary infection via primary herpetic gingivostomatitis
remains latent in dorsal ganglion, reactivation by trigeminal ganglia via sunlight, injury, trauma, stress, immunosuppression, hormones

17
Q

discuss management of recurrent herpes simplex virus

A

avoid triggers
antivirals for prodrome
acyclovir 5% cream - 2hrs
aciclovir 200mg tabs 5x 5 days

18
Q

what are potential complications of recurrent herpes simplex virus

A

disseminated herpes infection
bells palsy
erythema multiforme
herpetic whitlow
herpetic keratoconjunctivitis

19
Q

pt presents with
“white or red/white speckled buccal mucosa and labial commissure, corners of mouth lesions”

what is differential diagnosis

A

chronic hyperplastic candidosis

20
Q

risk factors for chronic hyperplastic candidosis

A

middle age men
smokers
poor OH
recent broad spectrum abx

diabetes

21
Q

gdp management of chronic hyperplastic candidosis

A

predisposing
systemic fluconazole
careful follow uo
dysplasia management - consider referral for biopsy

22
Q

what should a pt be informed of prior to a biopsy

A

purpose - rule out malignancy, definite diagnosis
procedure details
risks [bleeding, infection, scarring]
aftercare

23
Q

what steps to you take to mitigate risks of biopsy and ensure it is optimal for the reporting histopathologist

A

aseptic technique
atraumatic, LA
biopsy site selection so representative of lesion
adequate sample size
proper handling
clear labelling

24
Q

what features of histology would you see for chronic hyperplastic candidosis

A

hyperkeratosis
inflammatory infiltrate
acanthosis
parakeratosis

25
Q

which stain would you use to highlight organisms in fungal infection

A

PAS - periodic acid-schiff

highlights fungal cell walls

26
Q

what microorganism and what form
in chronic hyperplastic candidosis

A

candida albicans

hyphal or pseudohypal

27
Q

how would chronic hyperplastic candidosis be managed in OM

any risks associated

A

potential malignant disorder - 12.1%

systemic fluconazole, careful follow up, dysplasia management
