18F-FDG-PET, and microscopic and immunohistochemical findings of the skin biopsy specimen. (a) 18F-FDG accumulated in the axilla, intra-abdominal lymph nodes, inguinal region, and skin of bilateral upper extremities on a whole body 18F-FDG-PET scan performed one month after the onset. (b) A low-power view of a skin biopsy specimen of the right forearm taken 10 days after the onset of symptoms revealed that lymphoid cells had infiltrated around the vessels and appendages in the middle to deep dermis and subcutis. Bar = 1 mm (H&E staining) (original magnification: × 12.5). Bar = 500 μm (H&E staining) (original magnification: × 40) (inset). (c) A high-power view of the specimen revealed mitosis and anisonucleosis of these cells. Bar = 50 μm (H&E staining) (original magnification: × 400). (d) Immunohistochemistry revealed that these cells were positive for CD4 but negative for CD8. Bar = 50 μm (original magnification: × 400)
