Histological findings of soft tissue show atypical T-cell proliferation with angiocentric pattern in (A) hematoxylin-eosin stain (×200), and (B) CD3 immunohistochemical (IHC) stain. Additional IHC staining of cancer cells shows positivity for granzyme (C), CD68 (D), and EBV (F) but negativity for CD1a (E). These findings are consistent with nasal type extranodal NK/T cell lymphoma.
