Cutaneous plasmacytoma in three golden hamsters (Mesocrietus auratus).
Spontaneously occurring cutaneous tumours in three golden hamsters were characterized using histological, immunohistochemical and ultrastructural methods. Histologically, the tumours were composed of sheets of round to oval plasmacytoid cells with eccentrically placed nuclei. Tissue sections were weakly positive for anti-B lymphocyte antigen (BLA) staining. Ultrastructurally, large amounts of rough endoplasmic reticulum in the cytoplasm were observed. BLA positivity and characteristics of ultrastructure showed the plasma cell origin.
