Figure 3
Histopathological images. Biopsy samples taken from the mass lesion in the temporomandibular joint revealed monotonous infiltration of medium-sized lymphoid cells with a high nuclear-cytoplasmic ratio ((a) hematoxylin and eosin staining, original magnification: ×40). These cells were positive for TdT (b, ×40), CD20 (c, ×40), and CD10 (d, ×40) but negative for CD3 (e, ×40). Neoplastic lymphoma cells were also detected in the stomach (f: hematoxylin and eosin staining, ×40).
