MRI showed metastasis (white arrows) in the spinal cord.

Localized, dusky red colored, centrally umbilicated plaque, with a peripheral erythematous patch, on the left foot.

Tumor cells in the dermis were positive for CD3 (A, ×400) and negative for CD4 (B, ×400), CD8 (C, ×400), and βF1 (D, ×400).

(A, B) Epidermal atrophy, dermoepidermal vacuolization, massive cellular infiltration of the entire dermis, as well as a mostly lobular, inflammatory infiltrate of the subcutaneous fat of lymphoid cells and histiocytes (H&E, ×100). (C, D) At high power magnification, the "rimming" of fat cells by pleomorphic, atypical T lymphocytes in the subcutaneous fat was visible (H&E, ×400).
