Diagnosis of Langerhans Cell Histiocytosis on Fine Needle Aspiration Cytology : A Case Report and Review of the Cytology Literature

Abstract EN

A case of multifocal Langerhans cell histiocytosis in a two-year-old child is presented where fine needle aspiration was helpful in achieving a rapid and accurate diagnosis in an appropriate clinical and radiological setting.

This can avoid unnecessary biopsy and guide the management especially where access to histopathology is limited.

The highly characteristic common and rare cytological features are highlighted with focus on differential diagnoses and causes of pitfalls.
