title: Unusual presentation of metastatic involvement of a bone.
abstract: Metastatic involvement of a bone below the knee and elbow is rare. If it occurs it usually arises from primary tumours of the bronchus or pelvic organs, particularly the colon and the bladder. The case of a 58 years old male patient with recurrent transitional cell carcinoma of the bladder who presented with metastatic involvement of a metatarsal bone is presented. He presented with pain and swelling over the right foot. He was given antibiotic and there was no improvement, histopathological examination confirmed metastatic involvement of the metatarsal bone. To our knowledge, metastatic involvement of a bone below the knee has never been reported in Ethiopia.
