Abstract
Checkpoint inhibitors targeting CTLA4 (Cytotoxic T-lymphocyte antigen-4), PD-1 (programmed death)1 on lymphocytes and PD-L1 (programmed death ligand)1 on tumors cells are novel and promising treatment options for different types of cancer. But these agents are double edged swords, they undoubtedly robust the anti-tumor response but also throttle up the normal immunologic homeostasis. Autoimmune adverse reactions are very common with checkpoint inhibitors. We present a case of bullous pemphigoid, as an adverse reactions to Avelumab treated urinary bladder cancer with liver metastasis.

Description: A 4mm punch biopsy was taken from the vesicle on the left side of the chest, the section showed subepidermal blister containing plasma and sparse inflammatory cells. The Upper dermal layer showed perivascular lymphocytic
infiltrate with feweosinophils

Description: Direct immunofluorescence test shows a linear band along dermo-epidermal junction with IgG and C3
Heading
Description: Tzanck smear shows scarcity of epithelial cells and an abundance of leukocytes, particularly eosinophils. Routine blood investigations showed increased eosinophil count
