Two cases of paraneoplastic immunobullous disease occurring in women with gynaecological malignancies are reported. Both cases demonstrated mechanobullous mucocutaneous blistering as is typically seen in epidermolysis bullosa acquisita. Their immunopathology, however, favoured a dermal-binding mucous membrane pemphigoid (MMP) (or possibly bullous pemphigoid) for patient 1 and laminin-5 MMP for patient ...
