A tumoral calcinosis is considered a rare disorder with a poorly understood etiology. This uncommon soft tissue calcification is characterized clinically by the presence of an irregular, painless, periarticular soft tissue calcifying mass. People from African decent are mainly affected with the disease, which typically occurs in the periarticular regions. We report a case of a middle aged woman who complained a left inguinal subcutaneous mass. The characteristic clinical features, radiological and pathological findings are described. A diagnosis of a tumoral calcinosis can be difficult to make due to the unfailiarity of its clinical and radiological features. This presented report will help surgeons to easily diagnose this condition.

Tumoral calcinosis is a type of idiopathic calcinosis cutis which usually occurs around the large joints due to deposition of calcium phosphate, but extremely rare in the fingers which has been reported less than 20 cases in the literature. When it occurs on the fingers, it shows almost normal skin appearance and no specific symptoms except localized tenderness and numbness, therefore it is difficult to differential diagnosis among other common tumors on the fingers. In most cases surgical excision is performed before final diagnosis, and it is easy to misdiagnosis. The patient had mass like lesion which is enlarging for last 2 years at the radial side of the second finger without any trauma history. We prediagnosed the tumoral calcinosis with the simple radiologic test and laboratory tests and performed surgical excision without recurrence. So we report a case of tumoral calcinosis of the radial side of the second finger with brief review of the literature.

OBJECTIVETo explore the ultrasound (US) findings of partially cystic thyroid nodules (PCTNs) and to analyze their relationship with differential diagnosis of benign and malignant lesions.
METHODS265 cases of PCTNs confirmed by needle biopsy or surgical pathology were included in this study. Their ultrasound characteristics were reviewed and their significance in differential diagnosis was analyzed.
RESULTSIn the 265 PTCNs, 53 cases were malignant and 212 cases were benign lesions. According to the comparison of ultrasound and pathology results, there were 51 true-positive cases, 208 true negative cases, four false-positive cases and two false negative cases;the sensitivity was 96.2% (51/53), specificity was 98.1% (208/212), positive predictive value (PPV) was 92.7% (51/55), negative predictive values (NPV) was 99.0% (208/210), and accuracy rate was 97.7% (259/265). In terms of the PTCNs, internal structure, shape and margin were significantly associated with malignant or benign nature (P < 0.001); the aspect ratio ≥ 1, spiculated or micro-lobulated margin were significantly associated with malignancy; while the smooth margin, spongiform structure were significantly associated with benign nature. In terms of the internal solid portion of the nodules, the configuration, free margin, echogenecity, and calcification were significantly associated with malignant or benign nature (P < 0.001). The eccentric configuration with an acute angle, non-smooth free margin, hypoechogenecity, marked hypoechogenecity and micro-calcification were significantly associated with malignancy; while concentric configuration, smooth free margin, hyper/isoechogenicity, free margin of the solid component, and macro-calcifications were significantly associated with benign nature (P < 0.01). The results of logistic regression analysis showed that the echogenicity, free margin, configuration and calcification of the solid component were important predictive factors of malignant lesions (P < 0.05), that the hypoechogenecity, marked hypoechogenecity, eccentric configuration with an acute angle, non-smooth free margin and micro-calcification of the internal solid portion of the nodules were predictors for malignant PTCNs (P < 0.01).
CONCLUSIONUnderstanding the characteristics of US findings of partially cystic thyroid nodules is of great importance to make an accurate diagnosis of malignant nodules.

The diagnosis of soft tissue osteochondroma should be considered when a well-defined osseous mass is located in the soft tissues. The differential diagnosis includes myositis ossificans, tumoral calcinosis, synovial chondromatosis, and soft tissue osteosarcoma, true osteochondroma which arises from bone. One case of soft tissue osteochondroma in the knee, a lesion of uncertain pathogenesis is reported.

7.Large subcutaneous calcification in systemic lupus erythematosus: treatment with oral aluminum hydroxide administration followed by surgical excision.

A 32-year-old woman with a long-standing systemic lupus erythematosus had multiple subcutaneous nodules on her axillae, iliac crests and limbs. Three years ago, these nodules began to appear and slowly became larger. Some of them amassed to form a large, fungating, lobulated mass on her right iliac crest. Roentgenographic and histological examination showed that they were calcium deposits. She was initially treated with aluminum hydroxide administration for nine months, which resulted in moderate decrease in size and softening in consistency, but not complete resolution. Then, the mass on the right iliac crest was excised, with an excellent early result.

Subepidermal calcified nodule is a rare form of calcinosis cutis, which is not associated with any dermatologic or systemic diseases, and usually presents as a solitary hard nodule on the face or neck of children. A 25-month-old boy had a small pea-sized, tender nodule on his left sole that had been present for several months. There was no history of previous trauma or systemic illness. The clinical diagnosis as a viral wart was initially made and treated with cryotherapy. Because the lesion was not clear and a yellow-white firm papule was seen after cryotherapy, punch excision was done. Histologic examination showed cystic structure with calcium deposition in the upper dermis. Herein, we present the findings of a patient with a rare, solitary subepidermal calcified nodule on the sole.

Dermatomyositis is a multiple disease characterized by inflammatory myopathy with specific cutaneous findings including heliotroph erythema, Gottron's papules, lupus erythematosus-like skin lesions, and cutaneous calcinosis. We report a case of childhood dermatitis that developed in a 9-year-old girl. Skin lesion showed malar erythema, Gottron's papule, cutaneous calcinosis, poikiloderma, and scalp dermatitis. These were compatible with dermatomyositis. and other clinical, laboratory, and histopathologic findings supported the diagnosis of dermatomyositis. She was treated with methotrexate, oral corticosteroid, and hydroxychloroquine.
