Atypical Lipomatous Tumour (ALT) is a rare pseudosarcomatous soft tissue neoplasm which presents problems in both its diagnosis and nomenclature.
A 45- year old male presented with a large subcutaneous thigh mass of approximately three years duration. Fine Needle Aspiration (FNA) smears revealed mature fat tissue fragments alongwith atypical cells, often multinucleated, which had hyperchromatic, occasionally bizarre nuclei. Based on this pleomorphic cytomorphology, a diagnosis suggesting malignancy was forwarded. But the characteristic histopathologic appearance of the excised tumor coupled with its distinctive clinical presentation established the diagnosis of ALT. On review of the FN AC smears, the false impression created by this entity mimicking malignancy, was recognised and the potential pitfall in its cytodiagnosis realised.
The atypical cellular features of the aspirate of ALT can cause a diagnostic dilemma, but awareness of this uncommon condition holds the key to the correct diagnosis.
