Diagnosis of LCH is often difficult and can be delayed because of its rarity. The present study highlights the cytomorphological features in a large cohort of cases. An accurate cytological diagnosis may avoid unnecessary biopsy and guide appropriate management.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>Fourty seven (47) cases of LCH diagnosed on cytological material &amp; fine\u2010needle aspiration (FNA) over a period of 14 years (2003\u20102016) were retrieved from the archives.

The majority of cases were in the age group of 0\u20105 years. The most common site was head and neck region, which included cervical lymphadenopathy and scalp swelling. Two cases were diagnosed each from inguinal lymph node and bronchio\u2010alveolar lavage (BAL). Cytological smears in the majority of the cases were moderate to highly cellular (58%) and showing abundant Langerhans cell in (72%) of cases. Areas of necrosis were seen in 38%, while 78% of cases showed giant cells. The majority of cases showed mild eosinophilia (61%), sparse lymphocytosis (83%) and mild neutrophilic infiltration (64%). There were 1\u20102 mitoses per 10 high power field in 12 cases (25.5%). No abnormal mitoses were identified.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The
