Two patients with abnormal skeletal muscle uptake of Tc-99m hydroxymethylene diphosphonate following liver transplant: nephrogenic fibrosing dermopathy and graft vs host disease.
Tc-99m hydroxymethylene disphosphonate administered for skeletal scintigraphy may be seen in the extraosseous tissues for various etiologies. This report presents similar abnormal lower extremity skeletal muscle uptake in 2 patients status postorthotopic liver transplant. Although the history and scintigraphic appearance of the 2 were similar, subtle differences in cutaneous lesions and histology led to disparate diagnoses.
