Lingual neoplasia in nonhuman primates: Description of five cases and a literature review.

BACKGROUND

Documentation of lingual tumors is scarce in nonhuman primates.

METHODS

Through a multi-institutional retrospective study we compile cases of primary and metastatic neoplasia in non-human primates.

RESULTS

We describe five cases of lingual neoplasia. Three cases are primary lingual tumors: chondro-osteoblastic lipoma in a howler monkey, squamous cell carcinoma, and fibroma in two baboons. We describe two cases of metastatic lymphoma in the tongue in rhesus macaques. A literature review of published lingual neoplasia in nonhuman primates is included in this manuscript.

CONCLUSION

Lingual neoplasia is seldom reported in non-human primates.
