The patient, a 36-year-old female, was seen in the Second Hospital of Lanzhou University on September 5, 2025 mainly because she "found multiple subcutaneous masses all over her body for 2 months, cough with fever for 10 days". Two months ago, a subcutaneous mass, about the size of an egg, appeared on the anterior side of the patient's right thigh, and there was no redness, swelling, ulceration and tenderness on the local skin. One month ago, the patient developed multiple subcutaneous masses in the trunk and limbs. The patient experienced cough and fever 10 days before admission, with a maximum body temperature of 38 ℃. During the course of the disease, the patient felt fatigue, no night sweats, and lost 2 kg of weight. Physical examination: Multiple subcutaneous nodules in the neck, trunk and limbs, with asymmetric distribution, hard texture, no tenderness, poor mobility, and adhesion to surrounding tissues. Blood routine: white blood cells 2.64×109/L, hemoglobin 111 g/L, platelets 208×109/L; Procalcitonin 0.113 μ G/L, serum fungal 1,3-β-D-glucan (G-GM) test was negative, and two blood cultures were negative. Chest enhanced CT showed multiple round nodules in both lungs, with ground glass exudation around the nodules, and mild-moderate enhancement after enhancement (Figures 1 and 2, shown by arrows); Bilateral subclavicular and left axillary lymph nodes were enlarged. Positron emission tomography-computed tomography (PET-CT) showed lymph nodes of unequal size in both cervical, axillary, abdominopelvic and inguinal areas, nodules of unequal size in both lungs, nodules of unequal size subcutaneously throughout the body, and increased metabolism, all considering lymphoma involvement (Figure 3, indicated by arrows). Biopsy pathology of two subcutaneous nodules in the right upper limb showed that the tumor was abnormally proliferating neoplastic lymphoid cells, medium to large, diffusely distributed, accompanied by coagulative necrosis, and invading fat (Figure 4, indicated by arrows). The tumor cells expressed T-line markers and cytotoxic markers, CD56 and EBER were positive, and combined with other immunohistochemical staining, it was diagnosed as extranodal natural killer (NK) /T cell lymphoma (ENKTL) occurring in the skin. Immunohistochemical staining: CD3 (+), CD43 (+), CD56 (+), GranzymeB (+), TIA-1 (+), CD2 (+), CD20 (-), CKp (-), CD7 (-), Perforin (+), in situ hybridization EBER (+). Lymph node T cell receptor (TCR) clonality test showed: TCRD (+). Extranodal NK/T cell lymphoma was confirmed by multidisciplinary consultation. After being transferred to the hematology department, the patient was given chemotherapy with cyclophosphamide 0.4 g, vincristine sulfate 2 mg and dexamethasone 15 mg. The patient's body temperature returned to normal and was discharged. Follow-up until 26 Feb 2026, the patient received regular chemotherapy in another hospital (specific regimen unknown), and his condition was stable.
