Metachronous multicentric giant cell tumour (GCT) of bone is rare. We report a case of a 21-year-old man with metachronous multicentric GCTs, with five (including one recurrence) documented lesions reported over a span of 9 years involving various sites, which included the fifth metacarpal bone of the right hand, the intermediate cuneiform bone of the right foot, the left proximal humerus and the lateral malleolus of the right tibia. The radiological appearance of these lesions in these various sites with correlation among clinical history, histopathology and the treatment approach is described in this report. He is undergoing regular follow-up and has now once again presented with recurrence of the right tibial lesion. The case is reported for its rarity.
Most testicular tumors present as palpable scrotal lumps that progressively increase in size. Strangely some of these tumors regress spontaneously after they metastasize to the retroperitoneum and thus have been referred to as 'vanishing tumors' or 'burned-out' tumors. These 'burned-out' tumors are seen as focal testicular abnormalities with varied morphological patterns on sonography. About half of these so called 'burned-out' tumors still harbor malignant cells. It is therefore extremely important to identify these occult lesions as they have a significant bearing on patient management. Such a rare case is being presented here with a description of its varied imaging features.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
