11 Cases of Idiopathic Tumoral Calcinosis: A Single Center Experience / 대한피부과학회지

ABSTRACT

Background@#Tumoral calcinosis is characterized by the deposition of calcific masses around major joints, and it often causes significant impairment of joint function. Dermatologists sometimes encounter patients with a subcutaneous hard mass around the joint. However, there are few studies about tumoral calcinosis in the dermatologic literature, especially in Korea. @*Objective@#The aim of this study was to determine the clinical characteristics of tumoral calcinosis. @*Methods@#We reviewed the clinical photographs, medical records, and biopsy specimens of 11 cases of tumoral calcinosis seen at our clinic in 10 years. @*Results@#All 11 patients were female, and the mean age at onset was 58.5 years. The mean duration of the disease was 7.1 years. Most patients (9, 81.8%) presented with an asymptomatic subcutaneous hard mass around the iliac crest. None of the patients had a family history, or abnormal serum calcium, phosphorus, and parathyroid hormone levels. All patients underwent surgery for treatment. @*Conclusion@#Tumoral calcinosis can occur sporadically without metabolic disease. Therefore, careful history taking and biochemical work-up involving the metabolism of calcium and phosphorus should be performed. If there is no peculiarityon examination, the lesion is cured by resection. Although the sample size of this study is small, it can be inferred that the characteristics of tumoral calcinosis in Korea can be described by its predominant sex preponderance and location, that is, the female sex and the iliac crest, respectively.
