Pulmonary myxoma in a sheep.
Pulmonary myxoma is an uncommon neoplasm. A pale tan, lobulated, and well-circumscribed mass was discovered at slaughter in the left lung of a 5-year-old sheep. Histologically, the tumor was composed of spindloid to stellate cells in a myxoid matrix. Neoplastic cells were immunohistochemically positive for vimentin but did not express cytokeratins, S-100 protein, smooth muscle actin, desmin, or p53. On the basis of the histologic and immunohistochemical findings, this tumor was diagnosed as a myxoma.
