limb swelling

Bilateral lower limb swelling is a common clinical scenario with a wide differential diagnosis. We present a young man with gradually worsening bilateral leg swelling, who was diagnosed with eosinophilic fasciitis.
A 20 year old Hispanic male presented with a six week history of bilateral lower limb pain and swelling, later involving the upper limbs, but sparing the hands, feet and face. He had initial pitting, followed by non-pitting oedema and had a positive ‘groove sign’. With peripheral eosinophilia, a clinical diagnosis of eosinophilic fasciitis was suspected and was later confirmed on histology. He improved with prednisolone initially and is currently maintained on tapering prednisolone alongside methotrexate.
