Objectives: We aimed to clarify the definition, distribution, clinical association and outcomes of large calcinosis in patients with systemic sclerosis (SSc). Methods: We conducted a systematic literature review (SLR) focusing on SSc-related large calcified masses. Upon updating the terminology and definition, all cases of “pseudotumoral” calcinosis seen at the Cochin and Padova University Hospitals were reviewed. Results: The SLR yielded 30 SSc cases, with large calcified masses mainly defined as “tumoral” or “pseudotumoral”. Among the 629 SSc cases included in the Cochin and Padova cohorts, 19 (3%) living and 7 deceased patients were affected by pseudotumoral calcinosis; among these, the great majority had a severe vascular phenotype. The mean age in the whole population (56 cases) was 59 ± 11.4 years with a median disease duration at calcinosis onset of 7 (5–10) years. Twenty-five out of 56 patients (44.6%) had the diffuse cutaneous form of SSc. Anti-topisomerase I and anticentromere were found equally. Pseudotumoral calcinosis were commonly symmetrical and the size ranged from 2 to 15.5 cm. Most patients had multiple site involvement: 52% hand/wrist, 29% shoulders and elbows, 20% hips and 25% spinal calcinosis. Fistulization/ulceration and infections were reported in 32% and 23% of cases, respectively; nerve compression was found in 40% of spinal calcinosis and in one patient with limb calcinosis. There was no clear evidence of clinical and radiological improvement with any treatment. A partial improvement was seen in 7 patients that underwent surgery. Conclusion: Pseudotumoral calcinosis may occur in about 3% of SSc patients, commonly symmetrical and in multiple sites without differences regarding the cutaneous subtypes but often in those with a severe vascular phenotype. Medical treatment seems ineffective, whereas a surgical approach may be considered.

Abstract

Objectives: We aimed to clarify the definition, distribution, clinical association and outcomes of large calcinosis in patients with systemic sclerosis (SSc). Methods: We conducted a systematic literature review (SLR) focusing on SSc-related large calcified masses. Upon updating the terminology and definition, all cases of “pseudotumoral” calcinosis seen at the Cochin and Padova University Hospitals were reviewed. Results: The SLR yielded 30 SSc cases, with large calcified masses mainly defined as “tumoral” or “pseudotumoral”. Among the 629 SSc cases included in the Cochin and Padova cohorts, 19 (3%) living and 7 deceased patients were affected by pseudotumoral calcinosis; among these, the great majority had a severe vascular phenotype. The mean age in the whole population (56 cases) was 59 ± 11.4 years with a median disease duration at calcinosis onset of 7 (5–10) years. Twenty-five out of 56 patients (44.6%) had the diffuse cutaneous form of SSc. Anti-topisomerase I and anticentromere were found equally. Pseudotumoral calcinosis were commonly symmetrical and the size ranged from 2 to 15.5 cm. Most patients had multiple site involvement: 52% hand/wrist, 29% shoulders and elbows, 20% hips and 25% spinal calcinosis. Fistulization/ulceration and infections were reported in 32% and 23% of cases, respectively; nerve compression was found in 40% of spinal calcinosis and in one patient with limb calcinosis. There was no clear evidence of clinical and radiological improvement with any treatment. A partial improvement was seen in 7 patients that underwent surgery. Conclusion: Pseudotumoral calcinosis may occur in about 3% of SSc patients, commonly symmetrical and in multiple sites without differences regarding the cutaneous subtypes but often in those with a severe vascular phenotype. Medical treatment seems ineffective, whereas a surgical approach may be considered.
