Abstract
Objective: To analyze the clinical manifestations and laboratory features in patients with myeloid neoplasms complicated with clonal T large granular lymphocyte (T-LGL) proliferation. Methods: The clinical data of 5 patients with myeloid neoplasms complicated with clonal T-LGL proliferation from November 2017 to November 2018 in Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College were analyzed retrospectively. Results: The median age was 60 years old. All patients had a history of abnormal peripheral blood cell counts for over 6 months. The absolute lymphocyte count in peripheral blood was less than 1.0×10(9)/L. In addition to the typical T-LGL phenotype, the immunophenotype was heterogenous including CD4(+)CD8(-) in 2 patients, the other 3 CD4(-)CD8(+). Four patients were αβ type T cells, the other one was γδ type. STAT3 mutation was detected in 1 patient by next-generation sequencing, the other 4 cases were negative. Conclusions: Clonal T-LGL proliferation with myeloid neoplasm develops in an indolent manner, mainly in elderly patients. Hemocytopenia is the most common manifestation. The diagnosis of T-LGL proliferation does not have specific criteria, that it should be differentiated from other T cell proliferative disorders, such as T-cell clones of undetermined significance. STAT3 or STAT5b mutation may help distinguish.

Abstract
INTRODUCTION Multiple myeloma is a plasma cell neoplasm that is characterized by clonal proliferation of malignant plasma cell in the bone marrow along with M-protein in the serum and/or urine. Pancytopenia as a initial presentation of multiple myeloma is quite unusual. We are presenting a case series having pancytopenia as the presenting complaint. MATERIALS AND METHODS A retrospective study was conducted for a period of 30 months, wherein all the cases of multiple myeloma presenting with pancytopenia were included. The complete blood picture, peripheral smear examination, bone marrow aspirate & protein electrophoresis of all the cases were reviewed & analysed. RESULTS During the study period, 10 cases presented with pancytopenia with a mean age of 66.3 years (range: 59-72 years) at presentation with male: female ratio being 8:2. Fatigue and weakness was the most common symptom (100%) & average ESR was 104 mm/hour. High-resolution serum electrophoresis, showed a dense, sharp to wide M band in the gamma globulin region. Bone marrow plasma cell percentage was increased with an average of 63.1%. Bone marrow biopsy correlation was obtained in 100% cases. CONCLUSION Diagnosing multiple myeloma, presenting as pancytopenia requires a high degree of suspicion to avoid delay in initiation of treatment.
