Primary oat cell carcinoma of the larynx: an ultrastructural study.

An extrapulmonary oat cell carcinoma arising in the larynx is described. Ultrastructurally the tumor is identical to the oat cell carcinoma of pulmonary origin. The pressure of neurosecretory granules in our case strongly suggests that the tumor is derived from Kulchitsky-like cells, a histogenesis previously proposed for oat cell carcinoma of the lung.

Lymph-node infarction in two young men.

Benisch, Barry M., and Howard Rudolf G.: Lymph-node infarction in two young men. Am J Clin Pathol 63: 818-823, 1975. Two cases of massive lymph-node infarction in young men are described. Both patients had fever and lymphadenopathy and findings that suggested the possibility of viral infection. Follow up has revealed both patients to be asymptomatic, with lymphadenopathy, and with normal laboratory findings.
