Dermatofibrosarcoma protuberans is a rare, slowly growing, locally invasive spindle-cell tumor characterized by a protuberant cutaneous mass with a pronounced tendency to recur and by a prominent storiform histopathologic pattern'-'. We present a case of dermatofibrosarcoma protuberans with myxoid area on the chest of a 57-year-old man. The histopathological study showed a dermal tumor of uniform spindle-shaped cells with storiform pattern. Immunohistochemically, the tumor was stained positively to anti-CD34 antibody and negatively to anti-factor XIIIa antibody.

BACKGROUND: Glomus tumor is a benign neoplasm derived from the normal glomus body. This tumor includes the following types; solitary, multiple, proliferating, and acral arteriovenous. Histologically, it was subdivided into solid type, glomangioma, and glomangiomyoma. Its malignant counterpart - glomangiosarcoma - was reported. OBJECTIVES: The purposes of this study were aimed to evaluate the clinical and pathologic presentations of glomus tumor. METHODS: A total of 17 patients who have been diagnosed with glomus tumor by histopathologic examination were reviewed. RESULTS: Male patients were ten and female patients were seven. The age of the onset of glomus tumor varied from birth to 61 years. The location of tumors were as follows: arm (7 cases), finger (6 cases), back (2 cases), leg (1 case), foot (1 case). The digit was the most common site for female patients. Clinical manifestations showed solitary bluish papule (6 cases), subcutaneous nodule (5 cases), nail discoloration (3 cases), nail dystrophy (1 case), bluish plaque (1 case). One patient had no specific lesion but tenderness. The most characteristic symptom was pain in 15 (88.2%) of the 17 patients, and the other two patients had no symptom. Two asymptomatic lesions were located on the forearm and histopathologically showed glomangioma. Histopathologically, 13 (76.5%) of the 17 patients classified as solid type, and 4 (23.5%) the glomangioma variety. CONCLUSION: Glomus tumors were most commonly seen as a painful nodule on the upper extremity and especially female patients showed predilection for subungual location. We speculate that multiple, mild symptomatic lesions might be a tendency to be glomangioma.

Cutaneous mesenchymal hamartoma (CMH) is a very rare disease which most often presents itself at birth and is composed of collagen fibers, immature fibroblasts, fat cells, blood vessels, and mast cells. Until recently, only two cases have been reported. Thus, the clinical and histopathological findings have been unsettled. We describe three cases of cutaneous mesenchymal hamartoma with different clinical findings, discuss its pathogenesis, and suggest that CMH is a distinct disease entity.

PURPOSE: To evaluate and describe the efficacy and side effects of a percutaneous thrombin injection under ultrasonography guidance for the treatment of iatrogenic pseudoaneurysms. MATERIALS AND METHODS: Eighteen consecutive iatrogenic pseudoaneurysm cases were treated with a thrombin injection. The thrombin was injected into the pseudoaneurysm cavity using a 22-gauge needle under ultrasonographic guidance. The causes of the pseudoaneurysms are as follows: post coronary angiography (9 cases), percutaneous coronary balloon angioplasty (5 cases), cerebral angiography (1 case), transhepatic chemoembolization (1 case), percutaneous transfemoral arterial stent insertion (1 case) and bone marrow aspiration for a marrow transplant (1 case). RESULTS: Only one case required a secondary thrombin injection due to recurrent flow in the pseudoaneurysm lumen, which was detected at the follow up Doppler ultrasound. Other seventeen cases were successfully treated on the first trial. There were no technical failures or complication related to the procedure. The average amount of thrombin injected was 733 IU. Nine out of 18 treated patients (50%) showed mild reactions to the thrombin including mild fever (4 cases), chilling sensation (3 cases), a chilling sensation with mild dyspnea (1 case), mild chest discomfort (1 case) after the thrombin injection. All these side effects were transient and improved several hours later. CONCLUSION: All the iatrogenic pseudoaneurysms were treated successfully with an ultrasound-guided percutaneous thrombin injection. There was a high rate of hypersensitivity to the bovine thrombin, which precaution should be taken to prevent more serious side effects.

BACKGROUND: Mixed tumor of the skin or chondroid syringoma is a benign neoplasm characterized by histological features of a mixture of epithelial and mesenchymal components. It is a rare and benign appendageal tumor, found mostly on the head and neck, and present as an asymptomatic, firm, subcutaneous nodule. There have only been a few reported cases in Korea. OBJECTIVES: This study was aimed to characterize the clinical and histopathlological features of mixed tumor of the skin. METHODS: We reviewed the clinical data and histologic slides of seven patients who have been diagnosed with mixed tumor of the skin by histopathological examination. RESULTS: There were six male patients and only one female. Age of onset of mixed tumor of the skin varied from 26 to 65 years. A11 patients had the lesion on the head: perioral area (3 cases), nose (2 cases), cheek (1 case), and temple area (1 case). Each tumor was a solitary, asymptomatic, and firm, about 0.5-1.5 cm sized, subcutaneous nodule. Histopathologically, all 7 cases presented apocrine differentiation. Two cases showed follicular differentiation, and 2 cases showed sebaceous differentiation. Every tumor showed myxoid stroma except two with typical chondroid matrix. Adipose metaplasia of the matrix was present in 2 cases. In 3 cases, the so-called hyaline cells were rich in the stroma. CONCLUSION: Mixed tumor of the skin was most commonly seen as an asymptomatic, firm subcutaneous nodule on the head. Tumors showing apocrine differentiation were more common than that of eccrine differentiation, All 7 cases presented apocrine differentiation. Follicular and sebaceous differentiation might occur in apocrine type of mixed tumors of the skin. The stroma of mixed tumor of the skin might be myxoid, chondroid, or adipose.

PURPOSE: The aim of this study was to compare the surgical completeness and outcome of total thyroidectomy in two patient groups: One treated by harmonic scalpel (HS) and one by conventional total thyroidectomy (CT). METHODS: Between March 2006 and December 2007, 104 patients had total thyroidectomy by HS and 108 patients underwent CT. We analyzed clinicopathological characteristics and stimulated serum thyroid-stimulating hormone (TSH), thyroglobulin (Tg), and anti-Tg antibodies at the time of ablation for both groups. RESULTS: Compared with the CT group, the HS group had shorter operating time and hospital stays and reduced postoperative drainage. At postsurgical ablation, mean serum TSH was 80.47 +/- 21.77 mU/L in the HS group and 69.74 +/- 21.17 mU/L in the CT group, with significant between-group differences (P < 0.001). Mean serum Tg levels after TSH stimulation were 1.57 +/- 3.17 and 3.95 +/- 10.14 ng/mL in the HS and CT groups, respectively, with significant between-group differences (P = 0.028). CONCLUSION: Total thyroidectomy with an HS is a relatively safe and effective technique for use in patients with PTC. The HS provides surgical completeness and has a beneficial effect on successful ablation.

PURPOSE: We reviewed 604 cases of varicose veins managed in our hospital and the clinical feature and the results were analyzed between injection sclerotherapy and operative method. METHODS: Retrospective review of clinical records was done from January 1990 to June 1998. All of them were diagnosed as primary varicose veins of lower extremities. Sclerosing agents used were ethanolamine oleate, most commonly, hypertonic saline, sodium tetradecyl sulfate and sclerodex. Injections of the sclerosants were 1 to 5 times as the clinical courses. Then, elastic stocking was applied for 2 weeks. Operations were done under the spinal or general anesthesia and postoperatively remnant varicoses were managed by injection sclerotherapy. Student t-test was used in statistics. RESULTS: The distribution of age were 5th decade (36.8%), 6th decade (24.0%), 4th decade (22.2%) in order of frequency, and the mean age was 44.3 year and the male to female ratio was 1:4.0. The mean duration of illness was 12.6 year, and it was longer in female than male (13.2 vs. 8.7, p=0.02). The most common presumed predisposing factor was longstanding occupation (82% of all) and pregnancy was the 2nd in female (12.0%). Chief complaint was only cosmetic problem in 73% of patients and the others complained varicose induced symptoms and complications. Both lower extremities were involved in 41.9% and right leg was in 26.0%, left leg was in 32.1%. The locations of lesions were calf (41.4%), greater saphenous vein (34.6%), lesser saphenous vein (15.0%). Sclerotherapy was done in 48.0%, operation with sclerotherapy in 23.7%, operation only in 17.2%. The mean duration of illness in sclerotherapy group was significantly shorter than operation group (8.8 vs 14.7 year, p=0.0001). Operation methods were stab avulsion only (48.1%), greater saphenous vein stripping (37.3%) and perforator ligation (11.8%) and others. CONCLUSIONS: Injection sclerotherapy method is very effective and sufficient treatment modality in the management of lower extremity varicose vein with low recurrence and complication rate, especially in the early treated cases.
