case_images: The histological appearance of ENKL in case 1.. (A) The infiltration of lymphoma cells in the nasal cavity (HE 400x).. (B), (C), (D), (E) The immunohistochemical analysis of CD 3 (400x), CD 20 (400x), TIA-1 (400x) and EBER (400x). The immunohistochemical analysis demonstrated positivity for CD 3, TIA-1 and EBER, and negativity for CD 20.

case_images: In order to observe the spread of the lesions, positron emission tomography-computed tomography (PET-CT) was performed after the biopsy, and the accumulation of 18F-fluorodeoxy glucose (FDG) was observed in the mediastinal nodes, pleura, mesenteric nodes, uterus (bulky mass) and pelvic nodes (Figure 2).
case_images: The histological appearance of DLBCL in case 1.. (A) Infiltration of lymphoma cells in the uterine cervix (HE 400x).. (B), (C), (D), (E), (F) The immunohistochemical analysis of CD 3 (400x), CD 20 (400x), BCL-6 (400x), EBER (400x) and MIB-1 (400x). The immunohistochemical analysis demonstrated positivity for CD 20, BCL-6 and MIB-1, and negativity for CD 3 and EBER.
