Item Angioimmunoblastic T-Cell lymphoma: A critical analysis of clinical, morphologic and immunophenotypic features.(2010-10) Bal, Munita; Gujral, Sumeet; Gandhi, Jatin; Shet, Tanuja; Epari, Sreedhar; Subramanian, P GBackground: Angioimmunoblastic T-cell lymphoma (AITL), a subtype of peripheral T-cell lymphoma (PTCL), is characterized by unique clinical and biological features. Its diagnosis remains a challenge as clinical presentation as well as pathologic findings are frequently misleading. Material and Methods: We retrospectively analyzed the clinical, morphological and immunophenotypic spectrum of 17 cases of histologically proven AITL. Result: The mean age was 54 years and male to female ratio was 2.4. Common clinical features included generalized lymphadenopathy (60%), hepatomegaly (70%), splenomegaly (50%), anemia (80%) and polyclonal hypergammaglobulinemia (100%). Microscopically, three architectural patterns; pattern I (6%), pattern II (41%) and pattern III (53%) were observed. Bone marrow infiltration was seen in 60% cases and 30% cases revealed plasmacytosis. Absence of follicles, polymorphous infiltrate, extra-follicular follicular dendritic cell (FDC) proliferation, high endothelial venules (HEV) prominence and neoplastic T-cells were the diagnostic features of AITL. CD10 positivity (47%), clear cells in the background (59%) admixture with large size CD20+ B-immunoblasts (35%) and bone marrow plasmacytosis (50%) were common observations. Conclusion: Awareness of various morphological and immunophenotypic complexities of AITL and distinction from reactive adenopathies and other types of lymphomas that mimic AITL is underscored in this study.Item Frozen section is not cost beneficial for the assessment of margins in oral cancer(Indian Cancer Society, 2019-01) Datta, Sourav; Mishra, Aseem; Chaturvedi, Pankaj; Bal, Munita; Nair, Deepa; More, Yogesh; Ingole, Pranav; Sawakare, Sandeep; Agarwal, Jai Prakash; Kane, Shubhada V; Joshi, Poonam; Nair, Sudhir; D'Cruz, AnilBACKGROUND: Routine use of frozen section (FS) is a costly procedure and sparsely available in resource poor countries. A proper cost benefit analysis may help to reduce its routine use and would empower surgeons to perform oral cancer surgeries without having FS facility. FS is performed to identify microscopic spread beyond gross disease that cannot be assessed clinically. OBJECTIVE: Our primary aim was to determine the cost benefit analysis of FS in the assessment of margins in oral cavity squamous cell carcinoma (OSCC). MATERIALS AND METHODS: Retrospective study of prospectively collected data of 1311 consecutive patients who were operated between January 2012 and October 2013. The gross and microscopic margin status of each patient was extracted from the patient's chart. The cost estimates were performed to calculate the financial burden of FS as well as expenses incurred on adjuvant treatment resulting from inadequate margins. RESULT: Microscopic spread changed the gross margin status in 5.2% (65/1237) patients. Of this entire cohort of 1237 patients, FS helped 29 (2.3%) patients to achieve tumor free margin, and it changed the adjuvant treatment plan in 9 (0.7%) patients. The cost of FS for each patient was INR 11052. The cost-benefit ratio of FS was 12:1. Gross examination alone could have identified majority of the inadequate margins. CONCLUSION: Frozen section for assessment of margin status bears poor cost-benefit ratio. Meticulous gross examination of the entire surgical specimen is sufficient to identify majority of inadequate margins.Item Langerhans cell histiocytosis of thyroid: Case report with review of literature(Wolters Kluwer - Medknow, 2022-03) Yadav, Subhash C.; Bal, Munita; Patil, AsawariLangerhans cell histiocytosis (LCH) is a rare monoclonal disease of antigen presenting cells. Involvement of thyroid gland by LCH is exceedingly rare. Herein, we present a case of LCH involving the thyroid in a 38-year-old woman. Our patient presented clinically as a case of primary thyroid neoplasm. Presence of elongated, epithelioid neoplastic cells with grooved nuclei along with presence of background eosinophils were seen on fine-needle aspiration cytology (FNAC) and histopathology. Positive staining for CD1a and S100 immunohistochemistry confirmed the diagnosis of LCH. Patient was given combination chemotherapy and has responded well to the same without any complaints for last 6 months. With this report, our goal is to expand awareness of this rare tumor in the thyroid. Consideration at the time of FNAC and its correct diagnosis on subsequent excision is imperative for patient management.thyroidItem Primary intestinal T cell lymphomas in Indian patients - In search of enteropathic T cell lymphoma.(2010-07) Shet, Tanuja; Karpate, Arti; Bal, Munita; Gupta, Sudeep; Gujral, Sumeet; Nair, ReenaObjective: This series of six intestinal T cell lymphomas (ITCL) attempts to document enteropathy-associated T cell lymphoma (EATCL) in India. Materials and Methods: A total of six ITCL were selected from 170 gastrointestinal lymphomas in last 10 years. Results: The cases studied included EATCL (4), ITCL with a CD4 positive phenotype (1) and ITCL NK/T cell type (1). Of the four EATCL, two occurred in the ileum, one in right colon and one in duodenum. In three EATCL cases, there was history of celiac disease or lactose intolerance and enteropathic changes were noted in the adjacent mucosa. These tumors had CD3+/CD8+/CD56 (+/-)/CD4-/ Granzyme B+ immunophenotype. One EATCL was monomorphic small cell type (type II EATCL) with a CD3+/CD8-CD56+/CD4-/ Granzyme B+ phenotype. EBER- ISH (Epstein Barr virus coded RNA's- in situ hybridization) revealed positive tumor cells in ITCL NK/T cell type and in bystander cells in three EATCL. Conclusion: ITCL are rare in Indian patients but do occur and comprise a mixture of the enteropathic and non-enteropathic subtypes.
