Investigations for skin antibodies in malignant neoplasms

A group of 451 patients with various malignant neoplasms was investigated for the presence of antibodies against the intercellular substance in epidermis and against the basement membrane in the skin, using the immunofluorescence method. None of the patients had bullous disease. Circulating basement membrane antibodies were found in a 63-year-old man with lung cancer. None of the patients had antibodies against the intercellular substance. No in vivo bound intercellular or basement membrane antibodies were found.
