Why is it aphthous ulcers if there are no GI symptoms? Why can’t it be herpes zoster?

colonelred_ It’s just canker sores, they come and go. I think in herpes the gingivostomatitis really only happens when you first get infected. After that you just get recurrent cold sores. +1

hyoid Herpes zoster is not the same as herpes simplex virus. +7

bigjimbo you would see dermatome rash in zoster +1

kateinwonderland cf) Just in case someone wanted to know the causative organism of aphthous ulcers :The precise cause of canker sores remains unclear, though researchers suspect that a combination of factors contributes to outbreaks, even in the same person. Unlike cold sores, canker sores are not associated with herpes virus infections. +2

charcot_bouchard Herpes Zoster doesnt cause gingivostomatitis. Herpengina can cause vesicular lesion in mouth but happens to children in summer season by entero virus +

drdeeznuts1 I'm wondering if this could be a mild case of Behcet syndrome without genital involvement +

sherry It sure can be Behcet or Pemphigus if the q provides us with more info. Canker sores just come and go for years with unclear mechanism. Also herpes zoster is shingles by VZV, not HSV1. +
