S-antigen-like immunoreactivity in a human pineocytoma

Acta Neuropathol. 1986;69(1-2):165-7. doi: 10.1007/BF00687054.


A pineocytoma was investigated by means of immunocytochemistry with the use of a polyclonal antibody against bovine retinal S-antigen. Several cells of this tumor displayed strong S-antigen-like immunoreaction in analogy to certain pinealocytes in normal human pineal organs. This study indicates that S-antigen immunocytochemistry may be applied to characterize tumors of the pineal region.
