The fine structure of four small cell carcinomas of the lung is described. Cells from the tumor of one patient, who has a myasthenic syndrome, contained a well-developed, roughsurfaced endoplasmic reticulum and an enlarged Golgi apparatus. These were much less apparent in the three tumors unassociated with the myasthenic syndrome.
