Non-osseous soft tissue metastasis in the foot from renal cell carcinoma.

Metastatic tumours of the distal extremities, also known as acrometastases, are rare. The majority of the acrometastases involve bones-involvement of the soft tissues of the feet and hands is extremely rare. We report a case of clear cell renal cell carcinoma metastasised to the soft tissues of the foot. The patient presented with pain and swelling in his right foot. Diagnosis of acrometastases frequently gets delayed due to the rarity of this condition and resultant low clinical suspicion. Possibility of metastatic disease should be entertained as an important differential diagnosis when patients with a history of cancer present with musculoskeletal symptoms. A systematic evaluation incorporating thorough clinical assessment, advanced imaging techniques like MRI and pathological examination is critical to establish the diagnosis. © BMJ Publishing Group Limited 2020.
