Spindle cell lipoma, a rare variant of lipoma, is a benign tumor found in the posterior neck and shoulder. A 24-year-old man with a close family history of malignant lymphoma had presented with a large, firm, nodular mass found in the right supraclavicular area. Excision of the deeply located mass revealed a pale yellow, rubbery nodule which grossly resembled an enlarged lymph node, with a variant of lymphoma as a primary suspect. However, pathological studies revealed the lesion to be a spindle cell lipoma. Although atypical in location, spindle cell lipoma should always be kept in differential diagnosis of a newly-noted soft tissue mass, as this entity may be easily cured by simple excision.

Seven patients [six cases of left atrial myxoma, one case of right atrial myxoma] from 24 to 66 years of age [4 male and 3 female, mean age 48 years] underwent excision of atrial myxoma between 1982 and 1989 at Keimyung University Dongsan Medical Center. All patients presented with congestive heart failure, six with cardiac murmur, three with syncope, two with sinus tachycardia, one each with sinus arrhythmia, atrial fibrillation, pleural effusion, peripheral embolization. Symptoms were present from 1 month to 8 years before operation [mean 28 months], All tumors originated from atrial septum and pedunculated. The myxomas were successfully removed in all patients, either shaving them from atrial septum [n=3] or by excising a portion at normal atrial septum with tumor [n=4]. One case was replaced mitral valve with carbomedics-31mm due to severe mitral regurgitation. Follow up is current. No recurrent myxoma has been identified clinically or by echocardiography. In this series, excellent results were obtained by simple excision of the tumor, with or without a margin of normal atrial septum.

Eccrine porocarcinoma is a rare malignant tumor arising from the intraepidermal ductal portion of the eccrine sweat gland. It develops either spontaneously or from a long standing benign eccrine poroma. This entity usually affects older people and is commonly located on the lower extremities, the trunk, and the head. We report a case of eccrine porocarcinoma on the left cheek in an 85-year-old male. In our case, the tumor was treated with wide excision and postoperative adjuvant radiation therapy. The patient recovered well without local recurrence and distant metastasis during the 14-month follow-up period. Wide excision and postoperative adjuvant radiation therapy can be considered as a safe and effective treatment option in treating patients with eccrine porocarcinoma.

Dematofibrosarcoma protuberans(DFSP) is a moderate-degree malignant tumor with high recurrence rate and low metastasis rate, from soft tissue. Principle of treatment is wide excision or Mohs micrographic surgery(MMS). Although wide excision has been performed with surgical margins of 2-5 cm until nowadays, there are problems of preservation of surrounding normal tissue. Therefore the authors tried to identify desirable surgical margins and operative method. From January 1999 to April 2003, 12 patients with DFSP were operated. We applied different surgical margins and operative methods according to the location of lesions. On the face, we performed MMS with surgical margin of 3-4 mm in 2 cases although there are problems of operation time and expense. But on the extremities and trunk, we performed authors' method to begin excising with surgical margins of 1 cm and excise extensively with MMS by 1 cm in 4 cases after April, 2001 although we had performed wide excision with surgical margin of 3 cm in 6 cases before. There was no recurrence or metastasis in the follow-up period. So we think that author's method is effective in surgical excision of DFSP

We retrospectively reviewed the cases of peroneal nerve palsy in seven patients after musculoskeletal tumor resection. Their mean age was 38 years. Three had osteosarcoma in proximal fibula, 2 had chondrosarcoma in proximal fibula and calf and 2 had malignant fibrous histio cytoma in calf. Four of 7 patients had been managed using active dorsiflexion brace. Three patients who underwent tibialis posterior transfer and could walk without brace were able to discontinue the use of the orthosis. Peroneal nerve palsy after wide excision of tumor including peroneal nerve can not resolve spontaneously and results in severe functional disability. To improve the gait function, active surgical treatment should be considered.

Pleomorphic hyalinizing angiectatic tumor (PHAT) is a rare, low grade neoplasm which usually occurs in subcutaneous soft tissue. Histologically, it features ectatic blood filled vessels surrounded by hyalinized stroma and pleomorphic spindle cells. Clinically and histologically, PHAT could be misdiagnosed as such tumor as neurogenic tumor, malignant fibrous histiocytoma. About 100 cases of PHAT have been reported so far, and it is even rarer in head and neck area. We experienced a case of PHAT in 41-year-old male with several months of history of gradually enlarging neck mass which was surgically removed by wide excision.

Endolymphatic sac tumor is rare, locally aggressive hypervascular tumor of papillary structure, arising from the endolymphatic duct or sac in the posterior petrous bone. We present four cases with this tumor. Two patients were male and the other two were female. Age of each patient was 15, 52, 58, and 67 years. Three patients presented with progressive hearing loss and sustained vertigo for months to years and another one was referred for the tumor detected in routine medical check-up. Preoperative embolization was performed in 3 patients. Complete excision of the tumor was achieved in all patients using translabyrinthine or retrosigmoid approach. Herein, we describe the clinical and radiographic features, surgical treatment and pathologic findings with a review of the literature.

Granular cell tumor or also called Abrikossoff's tumor, is a rare benign tumor that can occur anywhere in the body. Granular cell tumor may single or multiple (synchronous or metachronous). Approximately half of all granular cell tumors occur in the head and neck. most commonly in the tongue. But granular cell tumors of the larynx are rare, accounting for only 7 to 10% of all reported cases. Laryngeal tumors are usually small and men are more frequently affected than women. The exact histogenesis is still not known but most recent data support the neurogenic Schwann cell origin. The preferred treatment is local excision using cold knife or laser. Radiation therapy is of little benefit. We report a case of granular cell tumor of the larynx which was confirmed by histopathology.

Osteoblastoma is a relatively rare benign bone tumor representing less than 1% of all bone tumors. The tumor usually involves the spine and sacrum of young individuals, less than 10% being localized to the skull, and nearly half of these affect the mandible, especially the posterior segments. In clinical finding, osteoblastoma present mainly with pain, swelling, and expansion of bone cortex. Radiographic appearances are variable, but frequently a well-delineated radiolucent lesion containing varying amounts of mineral deposits is seen. Histologically, ostoeblastoma is consists of irregular trabeculeae of osteoid and immature bone present within highly vascular connective tissue matrix. Osteoblastoma must be differentiated from a number of bone-producing lesions, including osteoid osteoma, fibrous dysplasia, ossifying fibroma, fibrous dysplasia, and osteosarcoma. If diagnosis may be mistaken for osteosarcoma, there are risks of more aggressive and irreversible treatment. Differential diagnosis of osteoblastoma is important. The preferred treatment of osteoblastoma is conservative approach and surgical excision. Recurrence following surgical intervention is rare. We treated osteoblastoma located in premolar area of mandible by excision with preservation of vital structure, such as nerves and teeth. So we report our clinical treatment with literature review

A parosteal lipoma is a benign tumor containing mature adipose tissue and is intimately related to the adjacent periosteum. We experienced a very rare case of parosteal lipoma arising from the shaft of femur. A 46 years old lady visited the hospital with complaining of slowly growing mass in her thigh for 7 month. Initially, it was difficult to differentiate from osteochondroma, parosteal osteosarcoma or liposarcoma. Based on the assessment of plain radiogram and magnetic resonance imaging, it was suspected the parosteal lipoma or osteosarcoma. Marginal excision was performed, and it was confirmed to parosteal lipoma histologically. We present the case with review of literatures.
