“…In the second case, a patient with generalized multiple abscesses was treated by antibiotics and developed acute kidney injury suspected to be drug‐induced acute interstitial nephritis; a renal biopsy was performed and revealed a tubulointerstitial infiltration of PTCL‐NOS. 4 The abdominal CT showed bilateral renal enlargement and no other extranodal lesions or lymphadenopathy. The current case was definitely different from the above two cases in that the renal function was normal and a solitary mass of the kidney could be identified.…”

IntroductionRenal involvement by non‐Hodgkin's lymphoma is very rare, and the kidney as the primary site of this lymphoma is much more uncommon. We report a case of primary renal peripheral T‐cell lymphoma, not otherwise specified, treated with partial nephrectomy.Case presentationA 63‐year‐old man was hospitalized with coronavirus infectious disease, emerged in 2019 in the emergency department. Computed tomography examination showed a 2‐cm renal mass in the right kidney. Abdominal enhanced computed tomography examination revealed that the noted mass showed good enhancement in the corticomedullary phase and washout in the nephrogenic phase. No metastatic lesions were found. He was diagnosed as having cT1aN0M0 renal cell carcinoma, and robotic‐assisted partial nephrectomy was carried out. The pathological diagnosis was peripheral T‐cell lymphoma, not otherwise specified. He has been followed for 20 months after robotic‐assisted partial nephrectomy without additional treatment and recurrence.ConclusionWe experienced a primary renal peripheral T‐cell lymphoma, not otherwise specified that was followed up without treatment after surgery.
