Figure 1: Clinical appearances: (a) the right pretibial area; (b) the inner aspect of the right lower leg; (c) the inner aspect of the left lower leg. (d and e) Ultrasound images. (f-h) Histopathology stained with Congo red ((f), ×4, (g), ×400). (h) H and E at ×400. (i) Green birefringence under polarized light. (j and k) Immunohistochemistry showed positivity for AL (kappa)-type amyloid deposition using polyclonal (j) and monoclonal (k) antibodies. Immunohistochemistry showed negativity for AL (lambda)-type amyloid (l), transthyretin (m) and amyloid A (n)
