Tumoral calcinosis: Two case reports and literature review

Tumoral calcinosis is a rare, benign disorder of extraosseous calcification. Due to its rarity, it is frequently misdiagnosed as a tumor-related disease in clinical practice. Both of the patients we have mentioned in this study have pathological calcification characteristics. The common denominator of these 2 cases is that the lesions are concentrated in the major joints, such as the shoulder and hip joints. After undergoing imaging and related laboratory tests, both patients were diagnosed with tumoral calcinosis. The patient had the lesion removed through surgery. After the surgery, the patient's symptoms were greatly improved, and the pain was significantly reduced. After analyzing and summarizing these cases and reviewing relevant imaging literature, we learned that the characteristic imaging manifestations of neocalcinosis have made great progress and effect on clinical diagnosis and later treatment. This knowledge can significantly aid in clinical diagnosis and treatment, thereby improving diagnostic rates and reducing instances of misdiagnosis.
