The systemic forms of scleroderma can cause small white calcium lumps to form under the skin on fingers or other areas of the body.

This is called calcinosis . The lumps may break through the skin and leak a chalky white liquid.

These most commonly occur on the hands, or near joints such as elbows or knees, although they may appear anywhere. Calcinosis may range from one very tiny deposit, to large (and often painful) clusters. (Also see Calcinosis Photos)

A few conditions other than scleroderma may also cause calcinosis, such as dermatomyositis, lupus, Vitamin D, tumors, and parasitic infections.

Calcinosis is one of the symptoms of CREST Syndrome, which is a form of systemic scleroderma. Calcinosis is not caused by too much calcium in the diet.

Are there risk factors for scleroderma-related calcinosis? Calcinosis was common in both limited and diffuse systemic sclerosis; both longer disease duration and osteoporosis were independently associated with calcinosis. PubMed, Mod Rheumatol, 2017 Jul 19:1-5.

Calcinosis is associated with digital ischaemia in systemic sclerosis (SSc) – a longitudinal study. Ischaemia may play a role in the development of calcinosis in SSc. PubMed, Rheumatology (Oxford), 09/04/2016. (Also see Digital Ulcers)

Calcinosis in systemic sclerosis (SSC): subsets, distribution and complications. Our data indicate that calcinosis may be classified in SSc as mousse, stone, net and plate according to its clinical and X–ray features. Oxford Journals Rheumatology, 05/30/2016.

Scleroderma Diagnosis. Calcinosis can be caused by many disorders. It can also be caused by systemic sclerosis. It is one of the criteria for diagnosis of Limited/CREST systemic scleroderma. ISN.

A few conditions other than scleroderma may also cause calcinosis, such as dermatomyositis, lupus, Vitamin D, tumors, and parasitic infections.

Sometimes calcinosis isn't visible, and is detected only by X-ray.

Calcinosis Cutis "Calcinosis cutis is a term used to describe a group of disorders in which calcium deposits form in the skin." Medscape.

Calcinosis in poly–dermatomyositis (DM): clinical and laboratory predictors and treatment options. DM diagnosis and positivity for PM/Scl and NXP-2 could all be considered risk factors which foresee the development of calcinosis. PubMed, Clin Exp Rheumatol, 2017 Mar-Apr;35(2):303-308.

Case Report: Acro–osteolysis and calcinosis in patient with scleroderma. We present a unique case of progressive acro–osteolysis of the distal phalanges and articular calcifications in a patient with scleroderma. PubMed, Acta Orthop Traumatol Turc. (Also see Bone Resorption)

Calcinosis: pathophysiology and management. This article reviews the most updated literature regarding the epidemiology, pathophysiology, diagnosis, and treatment of calcinosis cutis in patients with systemic sclerosis (SSc). PubMed, Curr Opin Rheumatol, 2015 Nov;27(6):542–8.

Late nailfold videocapillaroscopy (NVC) patterns associated with hand calcinosis and acro-osteolysis in systemic sclerosis (SSc). Acro–osteolysis and calcinosis are independently associated with the late NVC pattern, and particularly with severe capillary loss. PubMed, Arthritis Care Res (Hoboken), 07/20/2015. (Also see Bone Resorption in SSc and Nailfold videocapillaroscopy)


Generally, there is no treatment required for calcinosis, although surgical excision is sometimes done for extensive or very painful calcinosis.

Colchicine is often used to reduce inflammation associated with calcinosis. MedicineNet.

Calcinosis Cutis: WOC Nurse Management. Despite the lack of a standardized approach to treatment of calcinosis cutis, successful management of these patients was achieved by adhering to evidence-based wound-healing principles. PubMed, J Wound Ostomy Continence Nurs, 2018 Jan/Feb;45(1):83-86. (Also see Wound Healing in Systemic Scleroderma)

Safety and efficacy of extracorporeal shock wave therapy (ESWT) in calcinosis cutis associated with systemic sclerosis. Promising evidence was shown for safety and efficacy of ESWT for chronic, treatment resistant calcinosis cutis in SSc patients, thus justifying the initiation of larger multicentre controlled trials. PubMed, Clin Exp Rheumatol, 08/03/2016.

Systemic sclerosis (SSc) –related calcinosis. SSc–related calcinosis has received very little attention in terms of research into pathogenesis, measurement, and treatment and although we still do not have an effective treatment, progress is being made. Journal of Scleroderma and Related Disorders, JSRD 2016; 1(2): 194 - 203.

Validation of a Novel Radiographic Scoring System for Calcinosis Affecting the Hands of Patients with Systemic Sclerosis (SSc). We developed a novel radiographic scoring system that is feasible with excellent reliability, which accounts for the area coverage, density, and anatomic location of calcinosis affecting the hands in patients with SSc. PubMed, Arthritis Care Res.

(Case Report) Lumbar canal spinal stenosis due to axial skeletal calcinosis and heterotopic ossification in limited cutaneous systemic sclerosis: successful spinal decompression Peripheral cutaneous calcinosis is well recognized in lcSSc, but axial skeletal calcinosis is less common. We present a case of lcSSc with lumbar canal spinal stenosis due to calcinosis and heterotopic ossification that had successful decompressive spinal surgery. Rheumatology.
