The field of medical pathology uses the term angular cheilitis. I’m looking for a common word or phrase to use in place of this highly specialized technical term that I fear is likely to be known only by specialists.

It has several synonyms that are still too fancy for what I’m looking to use this for, including perlèche and rhagades. Is there any common term for this condition in English? My searches on Google were fruitless!

According to the the OED, cheilitis means:

Pathology. Inflammation of the lip.

It’s composed of two scientific forms: the combining form cheil‑, cheilo‑ from Greek χειλο- meaning lip, plus the suffix ‑itis meaning inflammation.

The Free Dictionary provides more details about this scientific term:

a disorder of the lips marked by scaling and fissures at the corners of the mouth; caused by a deficiency of riboflavin

What do regular people call this in English?

  • What is angular cheilitis? ...also called angular stomatitis, cheilosis and perleche (perlèche). – FumbleFingers Jul 26 '19 at 11:31
  • @FumbleFingers But are they common words in English? I mean, are they something like "mouth ulcer" or "canker sore" for "Aphthous stomatitis"? – BeatsMe Jul 26 '19 at 11:53

    It looks like the answer may well be 'No'. Have you tried medical sites, BM? There's a Medical Sciences SE, for instance. – Edwin Ashworth Jul 26 '19 at 12:07
  • I never knew there was such a thing – I certainly don’t know a word for it (or didn’t, until now). – Janus Bahs Jacquet Jul 26 '19 at 12:22
  • @BeatsMe I noticed that you were already linking to perlèche so I figure that’s still not the common term you’re looking for. I’ve therefore edited your question in the hopes of clarifying it. Please make sure my edit is in line with what you wanted to ask; if it isn’t, please don’t hesitate to remove anything I’ve added but which do not mean. – tchrist Jul 27 '19 at 17:05

    I presume from the description that it looks similar to a "cold sore". Is that correct? if so it is probably called a cold sore. In contrast I believe a Canker sore, also called aphthous ulcers, show up as open sores on the inside of your mouth not outside. – Brad Jul 26 '19 at 12:57

    What is the source of your quotation? Please provide attribution (and a link if possible)—otherwise, we could assume you simply made it up yourself. – Jason Bassford Jul 26 '19 at 13:49
  • @Brad This question has been very informative... I always had 'cold sores' as a child (which my mother treated with gentian violet, leading my teachers to continually ask if I had been chewing the end of a purple pen). I was vaguely puzzled that I never got them any more, since I clearly must have the virus. Due to this question I think I probably just had 'perleche' caused by the 'moist environment' generated by sucking my thumb... – Spagirl Jul 26 '19 at 14:11
  • I got the above quote from on line (Audio Dictionary) but maybe a better example is below from the BIOLOGY ONLINE DICTIONARY biology-online.org – Brad Jul 26 '19 at 15:18

    @tchrist - Based on comments above, It appears OP was looking for “cold sore” I think Brad should update his answer to include it. – Jim Jul 27 '19 at 19:20
