Fig 3 Microscopic analysis of the thymus of a patient with malignant melanoma. (A) Hematoxylin and eosin staining of the thymic tissue reveals diffuse brown pigments (original magnification ×400). Photomicrographs show (B) S-100 and (C) human melanoma black-45 are highly expressed in tumor cells (left side), but not in normal thymic tissue (right upper; original magnification ×100).
