Salivary duct carcinoma with striking neutrophil-tumor cell cannibalism
Cannibalism of neutrophils by tumor cells has previously been reported in certain carcinomas, lymphoma and melanoma. Tumor cannibalism is believed to serve as a tumor-immune escape mechanism, associated with high-grade aggressive cancers with a significantly increased metastatic potential. This inte...

Sumario: | Cannibalism of neutrophils by tumor cells has previously been reported in certain carcinomas, lymphoma and melanoma. Tumor cannibalism is believed to serve as a tumor-immune escape mechanism, associated with high-grade aggressive cancers with a significantly increased metastatic potential. This interesting phenomenon has not been previously documented in association with salivary gland tumors. We report, for the first time, striking neutrophil-tumor cell cannibalism associated with a high grade, aggressive and metastatic salivary duct carcinoma of the parotid gland highlighted within cytological and surgical excision pathology specimens. |
