Area of Science:

  • Dermatology
  • Allergology
  • Religious Studies

Background:

  • Tefillin (phylacteries) are ritual objects worn by observant Jewish men.
  • Allergic contact dermatitis (ACD) from tefillin is infrequently reported.
  • Previous literature documented only two cases of tefillin-related ACD.

Purpose of the Study:

  • To report new cases of allergic contact dermatitis associated with tefillin use.
  • To review the existing literature on contact allergies to religious items.
  • To identify the specific allergens responsible for tefillin-induced ACD.

Main Methods:

  • Case series describing 7 new patients with tefillin contact dermatitis.
  • Literature review of ACD related to religious objects and practices.
  • Patch testing to identify causative allergens.

Main Results:

  • Seven new cases of tefillin contact dermatitis were identified.
  • All 7 patients demonstrated allergic contact allergy to potassium dichromate.
  • Potassium dichromate was the sole identified allergen relevant to tefillin in this cohort.

Conclusions:

  • Potassium dichromate is a significant allergen in tefillin-associated allergic contact dermatitis.
  • Awareness of this allergen is crucial for diagnosing and managing ACD in users of religious articles.
  • Further investigation into materials used in religious objects may be warranted.
