Case 2440 8.11.19  (R. Carr)  M 65 nodules shins (great case!) 

Prurigo-nodularis-like lesions on shin.  Pseudo-epitheliomatous hyperplasia with neutrophil and eosinophil abscesses in follicles.  Caused by bromine and fluorine in inhalers.

Case 2876  15.7.21  (S. Taibjee) M 79 groin ulcerating nodules 

Many, including me thought this was pemphigus vegetans.  Combination of epidermal hyperplasia, microabscesses with neutrophils and eosinophils and a hint of acantholysis.  DIF -ve.   

Patient was using an inhaler containing glycopyrronium bromide.  Lesions settled after stopping it.
