Purpose : The aim of this study was to determine the magnetic resonance imaging (MRI) features associated with re-excision due to the presence of a positive margin after breast conserving therapy (BCT) in breast cancer patients. Materials and Methods: We reviewed the records of 286 consecutive breast cancer patients who received BCT between January 2006 and December 2007. Among 246 patients who had undergone BCT, 38 (15.4%) underwent immediate further surgery due to positive margin status. We analyzed the MRI findings using ${\chi}^2$ test, Fisher's exact test and t tests. Multivariate logistic regression was conducted for prediction of re-excision. Results: Tumor size (p < 0.001), lesion multiplicity (p = 0.003), and non-mass-like enhancement (NMLE) type on MRI (p < 0.001) were associated with margin involvement in BCT. On preoperative MRI, larger size (${\geq}5cm$) (odds ratio = 2.96), NMLE (odds ratio = 3.81), and multifocal lesions (odds ratio = 2.54) were positively associated with re-excision. In cases involving NMLE, segmental distribution was associated with a greater likelihood of immediate re-excision. Conclusion: Larger size, multiplicity, and NMLE on MRI are significantly associated with re-excision after BCT in breast cancer patients. For NMLE lesions, the segmental distribution pattern was predictive of re-excision.

Purpose: Due to local recurrence of tumor, metal failure usually develops in patients who underwent internal fixation or hip joint arthroplasty after curettage in the case of metastatic tumor of proximal femur. The aim of this study is to find out the appropriateness of reconstruction using recycling autograft after wide excision in the case of metastatic bone tumor by performing recycling autograft and hip joint arthroplasty after wide excision, and through presence or absence of local recurrence, functions of lower limbs and occurrence of complications. Materials and Methods: Five patients, in 6 cases, who had undergone reconstruction using recycling autograft prosthetic composite after wide excision in the metastatic tumor from May 2000 to May 2003 were included in this study. The average age of the patients was 60.8 years of age with male to female ratio of 3:2. Average duration of lives following surgery was 23.3 month (7-57 months). Primary lesion included 2 cases of lung cancer, and 1 each of stomach cancer, renal cancer and multiple myeloma. After wide excision, the hip joint was reconstructed with recycling autograft prosthetic composite ; 4 cases of extracorporeal irradiation and 2 cases of pasteurization. Musculoskeletal Tumor Society (MSTS) score(1993) for 6-month period after surgery, as well as presence of complication and local recurrence during the rest of their lives, were studied. Results: Average Musculoskeletal Tumor Society (MSTS) score over the 6-month period after surgery was 63.3% and 1 case of dislocation of hip joint, as a complication following surgery, was discovered. Local recurrence during the lives of the patients was not observed. Conclusion: In the case of metastatic tumor of proximal femur, in which the life span following surgery is expected to be more than 6 months, undergoing reconstruction using recycling autograft after wide excision, in comparison to internal fixation or hip joint arthroplasty after curettage, is deemed to have better results in prevention of local recurrence, and preservation of the functions of all limbs during the life span of the patient.

This is a case report of calcifying aponeurotic fibroma occurred in the right pterygopalatine fossa & ramus area accompanied by adenoid cystic carcinoma of the right sublingual gland of a 44-year-old female. Calcifying aponeurotic fibroma is benign tumor, but it is characterized by poorly marginated, infiltrated growth pattern and a stubborn tendency to local recurrence, but there is no record of malignant transformation or metastasis, and surgical management should be conservative(excision and reexcision). Most cases been reported at the hands and feet, but no reported case occuring in the head region is found in the literature. Adenoid cystic carcinoma is a slow-growing infiltrative tumor with high recurrence rate, and it's treatment requires radical excisin and radiotherapy. Wide surgical excision of tumor, RND and partial resection of mandible were done. And then, immediate mandibular reconstruction was performed by means of reimplantaion technique after autoclaving of the resected bone.

Adenoid cystic carcinoma (ACC) in the lacrimal gland is a very rare disease with poor overall prognosis. Its primary treatment is surgical excision, including orbital exenteration and radical orbitectomy, which is combined with radiotherapy and chemotherapy. Age, histopathologic type, bone invasion, and tumor extent are known factors that affect the prognosis of ACC. Furthermore, perineural invasion is highly associated with local tumor recurrence and tumor base invasion. Here, we report a rare case of ACC in the lacrimal gland with superior sagittal sinus invasion that repeatedly recurred after the surgical excision.

Lipoma is a benign neoplasm composed of mature fat cells and usually circumscribed by a fibrous capsule. The fat cells are arranged in irregular lobules, partitioned by fibrous septa with supportive vascular channels. Lipoma of the oral cavity is uncommon, and has been reported to be infrequent in the literature in the world so far. An oral lipoma mainly occurs in the cheek and tongue. Surgical excision is the only treatment recommended, and prognosis is uniformly excellent. Recently we experienced two cases of lipoma of the oral cavity and removed the tumor completely by surgical excision.

A sesamoid bone can occasionally be found under the interphalangeal joint of the hallux. These had anatomical variants and usually remain asymptomatic, it is uncommon for symptomatic cases of painful plantar keratoses or irreducible dislocation of interphalangeal joint of the hallux with incarcerated sesamoid. While the latter has a few cases, the former has not reported in Korea. We experienced a rare case of intractable plantar keratoses due to interphalangeal sesamoid bone of the hallux which may reqire excision.

Ganglion cysts causing suprascapular nerve compression are uncommon cause of suprascapular nerve entrapment. The advent of magnetic resonance imaging and its application in patients with shoulder pain has improved the ability to diagnose cystic lesions causing extrinsic compression of the suprascapular nerve. We present two cases of suprascapular nerve compression by ganglion cyst which was decompressed by surgical excision. Suprascapular nerve compression was also revealed by magnetic resonance imaging(MRI), electromyogram(EMG) and clinical present of muscle atrophy and motor weakness. In each case, the symptom was resolved after sugical excision of the cystic lesion. We experienced two cases of suprascapular nerve entrapment by ganglion cyst and report the clinical, radiological and pathological findings in detail.

Extensive tumoral calcinosis affecting a large joint is uncommon in patients with systemic sclerosis. We report the case of a 52-year-old female patient referred for a growing calcified mass in the shoulder. She was diagnosed with interstitial lung disease and progressive systemic sclerosis. Although the pain and disability associated with the affected joint was not severe, the patient underwent surgical excision because the mass continued to grow and was likely to produce shoulder dysfunction and skin ulceration. The patient appeared well 10 months after surgery with no signs of recurrence. This report highlights the timing and indication of surgical excision in similar cases.

Concomitant fracture of medial tubercle of posterior process and lateral process of the talus has not been reported in Korean literature. Association between fracture of lateral and posterior process of talus is not clear. We treated with open reduction and screw fixation in fracture of lateral process and with excision of fragment of posteromedial tubercle of posterior process with satisfying result.
