Lymphosarcoma of the Tonsil

Primary lymphosarcoma of the lung.

Schwannoma of the tonsil.

Between 25 and 48% of schwannomas have been reported to occur in the head and neck region; the acoustic nerve is involved in most cases. Schwannomas arising in the tonsil are extremely uncommon. We report a case of tonsillar schwannoma in a 23-year-old woman. We also review the literature on this rare entity.

Primary Lymphosarcoma of the Lung

Pulmonary involvement in disseminated lymphosarcoma is comparatively common. Vieta and Craver (1941) found an incidence of nearly 25% by radiographic assessment in a series of 239 patients with lymphosarcoma* and a similar proportion of a smaller number coming to necropsy. This figure agrees closely with the post-mortem incidence reported by Robbins (1953) in an even larger series. More recentl...

Transplantable Lymphosarcoma of the Chicken

The tumor described in this paper arose in a Leghorn chicken selected for examination because of its pale comb and emaciation. Examination of the blood revealed a severe change of erythroblastic type with the presence of numerous pathological elements difficult of classification. In nuclear structure the cells resembled at times lymphoblasts and at other times, hemocytoblasts. Nucleoli were pre...
