Retroperitoneal Inflammatory Liposarcoma in a Patient with Non-Hodgkin Lymphoma : A Report Highlighting Diagnostic Pitfalls

Abstract EN

Well differentiated liposarcoma (WDLS) is the commonest subtype of liposarcoma.

Recognised subtypes of WDLSs are lipoma-like, sclerosing, spindle cell and inflammatory.

The inflammatory variant of WDLS also known as “lymphocyte-rich liposarcoma” is rare.

We present a case of inflammatory WDLS occurring in the retroperitoneum, in a patient with a past history of non-Hodgkin lymphoma.

We outline the histological features, discuss the differential diagnoses and highlight the diagnostic pitfalls in interpretation of this lesion on fine needle biopsy.
