Calcinosis cutis involves the inappropriate deposition of calcium within the dermis layer of the skin, and is often associated with rheumatoid disease. A 42-year-old woman presented for evaluation of a hard palpable mass on the left upper eyelid. After everting the eyelid, a large papillomatous mass with a broad base was identified on the superior area of the tarsus. The lesion was partially excised posteriorly under local anesthesia, and pathologists identified the mass as calcinosis cutis. The patient had no systemic or trauma history, and the serum levels of calcium and phosphorous were normal. Idiopathic calcinosis cutis should be included in the differential diagnosis for a protruding papillomatous mass of the tarsal plate, and surgical debulking could be a viable option for large protruding lesions, although more follow-up is necessary to monitor regrowth.

Objective To investigate the effect of calcification on the ultrasound-guided radiofrequency ablation(RFA)of papillary thyroid carcinoma(PTC).Methods We retrospectively analyzed the preoperative and follow-up data of 164 patients(182 nodules)with PTC treated by percutaneous ultrasound-guided RFA in the First Medical Center of Chinese PLA General Hospital from January 1,2018 to December 31,2021.The tumor status 12 months after RFA was taken as the endpoint event.The univariate Logistic regression analysis was employed to predict the influencing factors of incomplete ablation.The factors were then included in the multivariate Logistic regression analysis for prediction of the independent risk factors of incomplete ablation.Results The maximum nodule diameter(OR=1.16,95%CI=1.04-1.29,P=0.009)and calcification ratio >2/3(OR=19.27,95%CI=4.02-92.28,P<0.001)were the factors influencing the disappearance of lesion 12 months after RFA.Conclusions PTC with calcification can be treated with ultrasound-guided RFA.In the case of calcification ratio ≤ 2/3,this therapy demonstrates the effect equivalent to that of no calcification.

We present a rare case of main pulmonary artery stenosis secondary to protruding fibrous material in the main pulmonary artery associated with patent ductus arteriosus. A 1-month-old baby boy manifested cardiac murmur. Echocardiogram showed circumferential high echogenic mass inside the main pulmonary artery with pressure gradient of 49 mmHg and patent ductus arteriosus. The mass did not regress during 3 months' follow-up period. Angiographic images showed that the circular filling defect was located at the main pulmonary artery distal to pulmonary valve, and pulmonary valve and both pulmonary arteries were normal. After surgical removal of the circumferential material and ductus ligation, the pressure gradient became negligible. The material was consisted of scarcely cellular fibrous tissue, abundant coagulum of fibrinous material and dense calcification.

OBJECTIVETo study the effect of close needling in the treatment of calcifying tendonitis.

METHODSSeventeen patients with calcifying tendonitis who had received close needling treatment were followed-up for 9.3 months on average. An 18-gauge or 16-gauge needle was used during needling. X-ray examination was given 4, 6, 8 and every 4 weeks after needling. SST (simple shoulder test) questionnaire, ASES (American Shoulder & Elbow Surgeon) score, constant-Murley score and UCLA score were adopted for evaluation before and after treatment.

RESULTSCalcium deposition disappeared within 4 - 20 weeks mean 9.4 weeks in 15 of the 17 patients after needling for 1 - 3 times. Average ASES score before treatment was 47.7 (34 - 59), forward elevation was 90 degrees (70 degrees - 100 degrees ), external rotation was 15 degrees (0 degrees - 30 degrees ), and internal rotation was L3-4 (L1-buttock). Average constant-Murley score before treatment was 44.6 (34 - 54), UCLA score was 11.6 (8 - 15), and numbers of questions for "yes" in SST questionnaire was 3.4 (2 - 5). After needling the average ASES score was 87.1 (72 - 91), forward elevation was 143.5 degrees (120 degrees - 160 degrees ), external rotation was 40 degrees (30 degrees - 50 degrees ), internal rotation was T(8)-T(9), constant-Murley score was 87.8 (64 - 94), UCLA score was 29.5 (19 - 33), and numbers of questions for "yes" in SST questionnaire was 9.1 (6 - 12). Significant difference was found between before and after needling (ASES: P < 0.01, forward elevation, external rotation and internal rotation: P < 0.01, constant-Murley: P < 0.01, UCLA: P < 0.01, SST: P < 0.01).

CONCLUSIONSClose needling is an effective method for the treatment of calcifying tendonitis. Symptoms and disability are greatly relieved non-surgically in most of patients. Care should be taken in differential diagnosis of degenerative calcification in chronic rotator cuff disease.

OBJECTIVETo evaluate the clinical application of high-frequency ultrasound-guided vacuum-assisted biopsy for breast microcalcifications.

METHODSSixty-six patients with 70 lesions of microcalcifications detected at mammography underwent high-frequency ultrasound-guided vacuum-assisted biopsy from July 2009 to October 2010. All patients were female, aged 24 to 61 years (median age 40 years). Among 70 lesions of microcalcifications, unilateral lesions were 62 cases and bilateral lesions were 4 cases. The clinical factors that affected the success of biopsy were investigated by χ(2) test and Logistic regression analysis.

RESULTSAmong 70 lesions of microcalcifications, the successful rate of biopsy was 72.9% (51/70). The biopsy successful rate of microcalcifications without and with masses were 65.2% (30/46) and 87.5% (21/34) respectively (χ(2) = 3.960, P = 0.047). The biopsy successful rate of microcalcifications of maximal diameter more than 5 mm was higher than that of maximal diameter less than 5 mm (88.9% vs. 55.9%, χ(2) = 9.633, P = 0.002). The Logistic regression analysis showed that the types and maximal diameter of microcalcifications were the main factors that affected the success of biopsy.

CONCLUSIONThe clinical application of high-frequency ultrasound-guided vacuum-assisted biopsy was an effective option for the diagnosis of breast microcalcifications, especially for the type of microcalcifications with masses and the maximal diameter more than 5 mm.
