[Anti-p200 pemphigoid with figurate exanthem : Rare cutaneous pattern of a bullous autoimmune dermatosis with...

A patient presented with bullous dermatosis. Clinically, the skin lesions showed a gyrate pattern resembling erythema gyratum repens (EGR). We diagnosed anti-p200 pemphigoid, which, like EGR, is a possible paraneoplasia. A search for tumors confirmed the presence of bronchial carcinoma. Other case reports with combined occurrence also point to underlying malignancies. This case highlights the importance of differential diagnosis in cases of figured efflorescences and bullous dermatoses and the need to investigate paraneoplasia.
