  • Primary cutaneous mucinous carcinoma (PCMC) is a rare low-grade malignant neoplasm derived from the eccrine glands. PCMC most commonly arises in the head and neck, with the eyelid being the most common site of origin. This case report describes a 51-year-old male with a painless, pigmented superficial nodular lesion over his right lower eyelid. The lesion was considered to be benign, and the initial treatment was simple excision with a 3-mm margin. However, histologic examination revealed the diagnosis of PCMC, and the patient underwent re-excision of the tumor site with an additional 3-mm margin from the initial scar. Histologic study of this second margin was free of any malignant cells. The patient experienced no postoperative complication or recurrence after 2 years. In our case, the skin lesion had benign morphologic findings and was strongly suspected to be a benign mass. Physicians should be aware of this tumor and be able to differentiate it from benign cystic or solid eyelid lesions.

  • Ameloblastoma is a benign neoplasm originating from odontogenic epithelium. It is the most common neoplasm in the jaws and is characterized by aggressive behavior and local invasion. Unicystic ameloblastoma (UA) has a unilocular feature in radiologic examination and a cystic feature histologically. Decompression and marsupialization are conservative method of treatment of large UA. The purpose of decompression and marsupialization are size reduction of the mass, which makes it easy to handle at total enucleation with protection of nerve damage and facial deformity. Here we report successful conservative treatment of extensive UA using decompression and marsupialization with a review of literatures.

  • Few articles have been written about the flexor tendon sheath ganglion in the finger, especially, between A1 pulley and A2 pulley. We report on rare cases of flexor tendon sheath ganglion with one symptomatic and two asymptomatic. All masses were evaluated using real-time ultrasonography and well-defined anechoic cystic lesions with posterior enhancement were observed. A 17-year-old female had a small mass at the 4th metacarpophalageal joint of her right hand, with pain and triggering. The patient underwent simple excision and a ganglion measuring $1.0{\times}0.8$ cm in size was derived from Camper's chiasm, between A1 pulley and A2 pulley. In two asymptomatic cases, ganglia measuring less than 0.5 cm in size observed. Based on our experience, real-time ultrasonography would be an excellent diagnostic modality in determining the treatment method in flexor tendon sheath ganglia, and surgical excision is recommended in symptomatic, especially triggering patients.

  • Hydatid disease is a parasitic infection that is caused by the larval stage of Echinococcus granulosus. This disease is distributed worldwide, but it is rare in Korea. A 34-year old foreign male worker from Mongolia presented with cough and chest discomfort. Computed tomography of. the chest showed a cystic mass in the upper lobe of the right lung. The cyst was surgically resected, and the pathological study confirmed a hydatid cyst. The patient was given albendazole postoperatively to prevent a relapse. We report here on a surgical case of pulmonary hydatid disease along with a review of the literature.

  • Background: Retrospective data on 165 patients who presented with a parotid mass and underwent surgery in our clinics during 2000-2009 were examined. The obtained data (demographic data, surgical procedures, histopathological diagnoses) were compared to similar studies to make contributions to the literature. Materials and Methods: Patients were classified according to their histopathological diagnosis. Surgical procedures and patient follow-up were clarified. The results are presented as means and standard deviations. Results: Of the 165 masses, 134 (81.3%) were benign and 31 (18.7%) were malignant. Pleomorphic adenoma was the most common benign tumour (79 patients, 59%). Lymphoma and adenoid cystic carcinoma were equally common and were the most common malignant parotid gland tumours (both 6 patients, 19.3%). The most frequent surgical procedure was superficial parotidectomy (92 patients, 55.7%), and the most commonly encountered surgical complication was facial paralysis (12 patients, 7.2%). Conclusions: Our data are generally in line with the literature but lymphoma was more common than in most previous reports. Although the number of cases was low, the high incidence of parotid gland lymphoma was remarkable.

  • The vast majority of schwannomas occur on cranial nerves, and rarely in the retroperitoneum. Solitary schwannoma in the psoas muscle is extremely rare. The authors present a case of retroperitoneal neoplasm in the psoas muscle identified as schwannoma which is not associated with von Recklinghausen's disease. A 68 years old female patient was admitted because of low back pain and weakness at the left leg. CT and MRI revealed a large cystic mass with well-defined margin and multiple internal septation within the left psoas muscle. The tumor was totally extirpated and histologically confirmed as a schwannoma.

  • First branchial cleft anomaly is a very rare disease and exhibits various clinical presentations. Therefore, the diagnosis of first branchial cleft anomaly may be difficult; the condition is often misdiagnosed and mismanaged. Accurate diagnosis is very important, because if not diagnosed correctly, patients with first branchial cleft anomaly would be treated with local incision and drainage repeatedly. We report two cases of first branchial cleft anomaly. The first patient visited for recurrent swell and discharge in the infra-auricular area with a history of previous incision and drainage. The other patient showed a cystic mass in the infra-auricular area and all of them were misdiagnosed initially by their treating specialists elsewhere. The objective of this study is to share our experiences of first branchial cleft anomaly, and emphasize its various clinical patterns and the significance of accurate diagnosis.

  • Vertical axillary muscle sparing thoracotomy is newly appeared and excellent alternative method of standard posterolateral thoracotomy.It has many advantages compared to standard posterolateral thoracotomy , less postoperative pain, well preserved thoracic muscle strength, full range of motion of the shoulder girdle and attractive cosmetic results. We performed vertical axillary muscle sparing thoracotomy in 36 patients from November 1993 to July 1994. The ages of the patients ranged from 6 months to 71 years[mean 45.1 years , and the patients consisted of 20 males and 16 females.The preoperative diagnosis were as follows : lung cancer in 17 patients, tbc destroyed lung in 7, bronchiectasis in 3, bullous emphysema in 3 and the others are mediastinal tumor, bronchogenic cyst, lung abscess, empyema, esophageal diverticulum, and CCAM [congenital cystic adenomatoid malformation . The operative procedures were as follows : lobectomy and bilobectomy in 16 patients, segmentectomy in 4, wedge resection in 3, penumonectomy in 7, and the others were open biopsy, lobectomy with diaphragm excision, sleeve right upper lobectomy, decortication, mediastinal mass excision, and esophageal diverticulectomy. We had 6 complications : postoperative bleeding in 2 cases, operative wound infection, arrrhythmia[atrial fibrillation , Horner`s syndrome, hoarseness. The subcutaneous seroma occurred in 4 cases but did not require drainage and relieved within 4 weeks spontaneously. We concluded that vertical axillary muscle sparing thoracotomy could be done in most of all thoracic surgery with safety. Comparing to standard posterolateral thoracotomy vertical axillary muscle sparing thoracotomy has many advantages such as less postoperative pain, well preserved muscle strengths and good cosmetic results.

  • We analyzed retrospectively the 74 patients with salivary tumors who were treated surgically at Chonbuk National University Hospital. The following results were obtained: 1) The most prevalent site was parotid gland and minor salivary gland is second in order. The most prevalent site of minor salivary gland tumor was palate. 2) Slow-growing painless mass was the most common chief complaints. 3) The most frequnet age incidence was 4th and 6th decades. 4) Sex ratio of male to female was 1:1.1, but in minor salivary gland tumor, female was more prevalent and sex ratio of male to female was 1:1.5. 5) Histopathologically, the most common salivary gland tumor was pleomorphic adenoma. Among the benign tumors, the pleomorphic adenoma was most common and Warthin's tumor was next. Among the malignant tumors, the mucoepidermoid carcinoma was most common and adenoid cystic carcinoma, adenocarcinoma were the next. 6) 59 patients with benign tumor and 15 patients with malignant tumor were treated with operative therapy. Among patients with malignant tumor, 12 patients were treated with postoperative radiation therapy. 7) Overall incidence of postoperative complication was 14.9% and the most common complication was transient facial nerve weakness and hematoma.

  • Distant metastases of head and neck cancer have become an increasingly common cause of death as local and regional control has improved. The most frequent metastatic sites of head and neck cancer are the lung, liver, bone and kidney; but metastases to the gastrointestinal tract, brain and heart have also been reported. We report a recent case of a 37-year-old male patient with squamous cell carcinoma of the tonsil who had undergone composite operation with left radical neck dissection and postoperative radiotherapy. The patient presented three years later, cachexic and complaining of severe deep seated headache. Radiologic evaluation revealed a cystic mass with peripheral enhancement in left temporal lobe that was proven to be metastatic cancer by burrhole exploration. However, in spite of various modalities, the patient expired.
