Study Design: We investigated LCR on IDS in 40 patients with proliferative lymphatic disorders (23 with B cell lymphoma, 13 with reactive lymphoid lesions, 2 with T cell lymphoma and 2 with Hodgkin's lymphoma). In addition, the results of flow cytometry (FCM) were compared in 34 of these patients. Results: On IDS, LCR was detected in 21 of 23 patients (91.3%) with B cell lymphoma. On FCM, it was detected in 15 of 21 patients (71.4%) with B cell lymphoma. Neither IDS nor FCM showed LCR in any patients with reactive lesions, T cell lymphoma or Hodgkin's lymphoma. Conclusion: IDS facilitated the detection of LCR with a single specimen under morphological observation. The application of this procedure may improve the accuracy of cytological diagnosis. en-copyright= kn-copyright= en-aut-name=ShimouraYasumasa en-aut-sei=Shimoura en-aut-mei=Yasumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SatoYasuharu en-aut-sei=Sato en-aut-mei=Yasuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakataKatsuyoshi en-aut-sei=Takata en-aut-mei=Katsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OritaYorihisa en-aut-sei=Orita en-aut-mei=Yorihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakamuraSatoko en-aut-sei=Nakamura en-aut-mei=Satoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ManoShyouhe en-aut-sei=Mano en-aut-mei=Shyouhe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshinoTadashi en-aut-sei=Yoshino en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=Kagawa Prefectural Cent Hosp, Clin Lab, Dept Pathol affil-num=2 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Pathol affil-num=3 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Pathol affil-num=4 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Otolaryngol Head & Neck Surg affil-num=5 en-affil= kn-affil=Kagawa Prefectural Cent Hosp, Clin Lab, Dept Pathol affil-num=6 en-affil= kn-affil=Kagawa Prefectural Cent Hosp, Clin Lab, Dept Pathol affil-num=7 en-affil= kn-affil=Okayama Univ, Grad Sch Med Dent & Pharmaceut Sci, Dept Pathol en-keyword=Cytology kn-keyword=Cytology en-keyword=Immunocytochemical kn-keyword=Immunocytochemical en-keyword=double staining kn-keyword=double staining en-keyword=Immunoglobulin light-chain restriction kn-keyword=Immunoglobulin light-chain restriction en-keyword=Lymph node kn-keyword=Lymph node en-keyword=B cell lymphoma kn-keyword=B cell lymphoma en-keyword=Flow cytometry kn-keyword=Flow cytometry END
