Abstract

INTRODUCTION: Hodgkin's lymphoma (HL) is a lymphoproliferative neoplasm constituting less than 1% of all neoplasms. It has been categorized into- nodular lymphocyte predominant HL and classical type with subtypeslymphocyte rich, lymphocyte depleted, nodular sclerosis and mixed cellularity. Nodular sclerosis Hodgkin's lymphoma (NSHL) is difcult to diagnose on FNA because of the lack of Reed Sternberg (RS) cells, low cellularity and difculty in identifying the counterpart of lacunar cells. CASE A 16-year-old female presented with anterior chest wall swelling si REPORT: nce 6 months measuring 5x4cm along with incidentally noted cervical lymph nodes measuring 2x2cm and 1x1cm. On examination, multiple papular skin lesions were observed. FNAC smears from cervical lymph node showed high cellularity, with sheets of binucleated and multinucleated cells having multiple nucleoli, some showing pale bluish abundant cytoplasm whereas others showing dense cytoplasm; in a background of reactive lymphoid population with few neutrophils. Few giant cells showed hyperchromatic nuclei. Abnormal mitosis seen. No typical RS cell was seen. Peripheral blood smear showed neutrophilic leukocytosis with no atypical cell. Possibility of NSHL was considered and biopsy advised to rule out ALCL. Histological sections showed near total effacement of lymph node architecture by nodules separated by broad brotic bands. These nodules exhibit proliferating lymphocytes with clustered lacunar cells along with some mononucleate, binucleate and multinucleated cells. Prominent mitotic activity, angiogenesis, focal micro abscesses were noted. Immunohistochemistry showed CD 15+ and CD 30+ expression in the giant cells, conrming diagnosis of NSHL grade 2. NSHL poses a cytological diagnostic dilemma specially in abse CONCLUSION: nce of sclerosis on FNA, making histological examination and IHC mandatory
