A seven-year-old female common marmoset (Callithrix jacchus) presented with weight loss. Imaging revealed a left thoracic mass, confirmed at necropsy. Histology and immunohistochemistry suggested a well-differentiated pulmonary adenocarcinoma. No evidence of local lymphovascular invasion or distant metastasis was observed. This is the first report of pulmonary adenocarcinoma in marmosets.
