{Reference Type}: Case Reports {Title}: Osteopetrosis in a Patient of Systemic Sclerosis Sine Scleroderma: A Rare Association. {Author}: Pati SK;Raja P;Behera AK;Ranganath TG;Bodhey NK; {Journal}: Indian J Radiol Imaging {Volume}: 31 {Issue}: 4 {Year}: Oct 2021 暂无{DOI}: 10.1055/s-0041-1740506 {Abstract}: Systemic sclerosis is a connective tissue disorder of unknown etiology. Although it is a multisystemic disorder, skin thickening is considered as a hallmark of the disease. It usually involves the lungs, gastrointestinal, and musculoskeletal systems. However, a rare subset of systemic sclerosis, systemic sclerosis sine scleroderma, is characterized by internal organ involvement and positive serologic markers with the total or partial absence of cutaneous manifestations. We present a rare association of osteopetrosis in a case of systemic sclerosis sine scleroderma, in a 22-year-old male patient, who presented with pulmonary symptoms as his chief complaints, unreported so far in literature.
