they're also caused by stress. I got 3 in my mouth the day after Prometric canceled my test for the 3rd time!

In layman terms, these things are called canker sores. I also get them on my tongue sometimes - super painful especially when it makes contact with anything salty.
Just like @thisshouldbefree, it's usually preceded by mucosa damage (ie biting my tongue accidentally while eating)

The physiological corollary of psychological โstressโ is cortisol and its many cousins (corticosteroids, et cetera). Cortisol suppresses the โnormalโ but energetically costly process of dermal maintenance and growth (basal stem cell division, skin + epidermal turnover, including in the mucosa). So, in the presence of high โstressโ, normal mucosal maintenance is sacrificed. This is because some other, more important existential threat is happening in the body. The result is stuff like aphthous ulcers, since your body is literally neglecting your mucosa, allowing it to โthin outโ to preserve energy to address some other major systemic issue.

From https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5181654/?report=classic: The glucocorticoid receptor (GR) is highly expressed in the basal cells but it is barely detectable in the other layers of the epidermis (22). The localization of the GR in basal corneocytes, as well as the negative effects of glucocorticoids on keratinocyte growth factor and type-I and-III collagen gene expression (23โ26) suggest that endogenous cortisol in CS suppresses not only wound healing but also normal skin growth and turnover.

^ btw, CS = Cushing Syndrome (hypercortisolism)

Herpangia would occur in the posterior oropharynx--> caused by Coxsakie A NOT HSV

I have some in my mouth rn... 2 weeks to my step... they can be food or stress induced and its more common in some regions more than others. in Middle East and Asia it seems to be common.

Itโs 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.

Herpes zoster is not the same as herpes simplex virus.

you would see dermatome rash in zoster

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.

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

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

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.

Most pictures on google show herpangina being present on the hard palate/throat, while aphthous ulcers are commonly on the lower lip. I think his lack of genital lesions are pointing us away from herpangina.

I get these VERY often. I seem to get them only after eating something that can damage the mucosa in my mouth such as hard chips (Tostitos, very jagged very pain). These are NOT cold sores (HSV). This is simply a aphthous ulcer; they can be stress induced (studying for hard test). they are very painful and do reoccur. there are no associated sx with them.
