Clinical images of NK/T-cell lymphoma. (A) A large ulcer that on biopsy showed NK/T-cell lymphoma. Scars (arrows) were attributed by the patient to be due to ulcers that healed from previous mosquito bite hypersensitivity, occurring over a period of decades. There was almost complete healing of the ulcer after 2 courses of SMILE (right side). (B) Typical PET/CT image of a nasal lymphoma. (C) Relapse of nasal NK/T-cell lymphoma in the mediastinum. (D) Disseminated NK-cell lymphoma showing diffuse splenic uptake. (E) Relapsed cutaneous NK/T-cell lymphoma. The lesion was very subtle and showed up on PET/CT with a low SUVmax. This patient presented with multiple skin lesions.
