Pre-operative diagnosis for dermatoses due to tonsillar focal infections: recent views.

The recent views on the pre-operative diagnosis for dermatoses possibly due to tonsillar focal infections were presented as follows: 1) the range of dermatoses which may be related to tonsillar focal infection and may be indications for tonsillectomy, was introduced based on a questionnaire sent to departments of dermatology and otorhinolaryngology throughout Japan; 2) provocation test using direct stimulation with ultra-short waves and inhibition test with Impletol for the pre-operative diagnosis in patients with Pustulosis palmaris et plantaris, which appears to have a relatively high prevalence and the highest possibility of induction by tonsillar focal infection; 3) the selection of timing of the tonsillectomy in patients with Pustulosis palmaris et plantaris; and 4) the necessity of diagnostic and therapeutic alliance between dermatologists and otorhinolaryngologists.
