Bullous pemphigoid and ovarian cystadenocarcinoma. Immunologic studies

A patient with bullous pemphigoid and papillary serous cystadenocarcinoma of the ovary was studied to determine if patient tumor cells would absorb antiepithelial basement membrane antibody present in patient serum. Absorption of patient serum with trypsinized tumor cells failed to decrease the titer of serum antibasement membrane antibodies. These studies present additional evidence that malignant neoplasms and bullous pemphigoid are not causatively related.
