Five patients in deep coma due to extensive supratentorial lesions presented roving lateral eye movements (ping-pong gaze), distinguished by the fact that the eyes, after moving to one extreme of gaze, returned to the midline instead of to the opposite extreme. The phenomenon was reported recently by Reynard et al.

A case of palpebral nystagmus is reported. Two infarcts were present in the rostral pons, caudal midbrain and in the periaqueductal gray matter between the red nuclei, ventrally to the posterior commissure. The relationships between the palpebral nystagmus and the retraction of the upper lid together with the clinico-pathological significance of the two signs is discussed.

Report of a case of typical bobbing occasionally interpolated by reverse bobbing. The causative lesion, which lay in the most dorsal median portion of the pontine tegmentum, was a small primary hemorrhage, diagnosed in life by CT scanning and confirmed at necropsy. The pathological and clinical correlations of the phenomenon are discussed.

Four cases of malignant histiocytoma in children are reported. Malignant histiocytoma is defined as a histologic variant of fibrohistiocytoma, characterized by a histologic absence of a fibroblastic component, and a predominant proliferation of malignant histiocytes with an epithelial-like appearance. However, the ultrastructural study of one case also revealed the presence of fibroblasts. Thus, an authentically pure form of malignant histiocytoma does not exist. Nonetheless, it is important to emphasize the histologic distinctions between malignant histiocytoma and malignant fibrohistiocytoma and to emphasize the possible differences in their biologic behavior.
