Case Number : Case 2950 - 27 October 2021 Posted By: Dr. Hafeez Diwan

?Bullosis diabeticorum

Subepidermal cleft with eosinophils. Cell-rich bullous pemphigoid is the first possibility. Gliptin-induced pemphigoid is a newly emerging disorder in diabetics, which is a second possibility.

sub epidermal bulla with eosinophils. could be drug induced BP or BP immune mediated. What is the blue color, is it mucin staining. if there is mucin in a bulla in the knuckle must we exclude dermatomyositis ?

BP

Cell-poor blister, basal lamina duplication, copious amounts of mucin..make me think of Dermatomyositis.

I thought subepidermal blister with eosinophils and in that age more drug related i would think

Bullous diabeticorum. Immunofluorescence studies were negative.
