Purpose: Anaplastic large cell lymphoma, has the following three characteristics of a malignant lymphoma; 1) An irregular large nucleus, called pathologic atypical cells, 2) Eosinophilic cytoplasm, 3) Immunologically positive for Ki-1. Anaplastic large cell lymphoma occurs mostly in the lymph nodes, but about 40% has been observed to occur in other tissues. Skin is the one of the main sources of origin and it is called 'primary cutaneous anaplastic large cell lymphoma'. Methods: A 69-year-old male patient with an erythematous nodule, sized $1.5{\times}1.7cm$ on his right hand dorsum was excised under local anesthesia and on biopsy was diagnosed as 'Dermatofibrosarcoma Protuberans'. Three months after the local excision and biopsy, same natured mass reoccurred in the same region, and then spontaneous regressed after three weeks. However, metastatic large mass of $4.0{\times}5.0cm$, of same nature was observed on the elbow. The large mass was operated with wide excision and biopsy. Results: On final diagnosis, with an immunofluorescent stain with CD30(Ki-1), 'Primary cutaneous large cell lymphoma' was made. After follow up for three years, we did not observed recurrence and metastasis. Conclusion: We have reported that we have diagnosed primary cutaneous large cell lymphoma and treated without recurrence and metastasis.

Microcystic adnexal carcinoma is a rare type of tumor, with about 300 cases reported globally. Due to its similar histology with other tumors, it is occasionally misdiagnosed as desmoplastic trichoepithelioma, basal cell carcinoma, syringoma, and so on. We present a patient with a mass on the perioral area who was preoperatively diagnosed with trichoepithelioma. Microcystic adnexal carcinoma was diagnosed after excisional biopsy and a wide excision. Defects were reconstructed with a mucosal advancement flap. There was no recurrence and there were no significant complications during the 18-month follow-up period. Because superficial punch biopsy has limitations in width and depth, surgeons should always consider the possibility of malignancy of a mass even if a biopsy shows a benign result.

Objective: This study is undertaken to review the characteristics, risk factors and the surgical outcomes in long term follow-up of brain abscesses. Methods: We had reviewed medical records and radiological findings in patients with brain abscess who underwent operations in our hospital from January 1992 to June 2003. Results: Observed 11 cases were comprised of 8 men and 3 women with 42 years old average age ranging from 17 to 66. Lesions were located at frontal lobe in 5 cases, parietal in 4 cases, temporal in 1 case, and occipital in 1 case. The mean follow-up period was 23.8 months and ranged from 5 to 33 months. The microbial sources of infection had been found in 5 cases (45%). The organisms were identified by using the microbial culture obtained from the excisional biopsy. We had applied all cases with surgical excision. Empirical antibiotic treatment started soon after diagnosis in all cases. The mortality and morbidity of surgical excision were low. Nine patients were neurologically improved. One patient had died after the operation due to acute respiratory distress syndrome (ARDS). Conclusion: The single and large abscess located in an accessible lesion is a good candidate for surgical excision because of it's low morbidity, mortality, and favorable outcome after surgical excision. Further study is required to compare the surgical excision with other treatment modalities of brain abscess.

Percutaneous transthoracic fine needle biopsy has been widely used In the diagnosis of pulmonary lesions especially lung cancer. Onc of the rarest complication's is that malignant cells are implanted within the needle tract and developed a chest wall mass subsequently. Wc expcrlenccd a case of chest wall implantatio of lung cancer after percutaneous transthoracic floe needle biopsy. A 65-ycar old man had undergone bilobectomy (right upper lobe and right middle lobe)for squamous cell (·4rcinoma (TINOMO) of the lung. 60 days after percutaneous biopsy (48 days after operation), a tiny nodule (1 mm sized) was notcd at the right anterior chcst wall where the diagnostic fine needle biopsy had been performed before operation. This tiny mass was rapidly growing to 1.5 cm sized mass for 20 days. We carried out wide excision of chest wall mass and skin grafting, and confirmed squamous cell carcinoma histopathologically as same as the lung cancer.

Background: Neuroblastoma is the third most common malignancy of chidhood, and is the most common mediastinal mass in children under the age of 2 years. However, the results of surgical treatment have been seldomly reported in Korea. Therefore, we analyzed the results of surgical treatment in children with neuroblastoma and its influencing factors. Material and Method: We studied the clinical characteristics and prognosis of 12 children, 11 makes and 1 female, whose primary thoracic neurobalstomas or ganglioneuroblastomas were diagnosed and operated between 1977 and 1997. Men age at presentation was 29.9 months. Result: Respiratory symptoms were the modes of performed in 9 patients. Complete excision, partial excision, and biopsy only were performed in 9, 2, and 1 patients respectively. Ten patients of thoractic neuroblastomas survived (83.3%) during follow-up period. Conclusion: The postoperatve 5-year survival of thoracic neuroblastoma was 76.4% and the prognosis was related to the stage of neuroblastoma. We suggest that complete resection should be considered as preferential method in the treatment of thoracic neuroblastoma in children, especially with early stage.

We reported on a rare case of recurred macrodystrophia lipomatosa of the foot, and reviewed the literature. A 62-year-old male patient presented with right foot second toe pain; preoperative magnetic resonance imaging and radiograph examination was performed. After surgery the biopsy confirmed the diagnosis. American Orthopaedic Foot and Ankle Society score was checked before and after surgery. Wide excision of the affected area including ray amputation is an effective way to prevent recurrence and relieve the pain after surgery. The 2nd toe ray amputation was performed in the treatment of recurred macrodystrophia lipomatosa of the foot, and is thought to be an effective way to relieve pain and prevent recurrence. After minimally invasive surgery with complete excision surgery, additional data on recurrence and pain relief rate are needed.

A 65-year-old woman presented with a solid mass on the right temporal area. The mass had grown for over 2 years without any initiating event of trauma or inflammation. Before excision, the patient went through a computed tomography scan, revealing a calcified mass without bony connection. Under general anesthesia, an excisional biopsy was performed. Microscopic examination confirmed a diagnosis of soft tissue osteoma. Soft tissue osteoma is rare, especially in the head and neck region. Osteomas in the temporal region have not been reported yet. Due to its rarity, osteoma might be misdiagnosed as another soft tissue or bone origin tumor. Its treatment of choice is simple excision. In this review, we present an unusual clinical form of soft tissue osteoma.

Malignant pilomatricoma (pilomatrical carcinoma) is a rare, locally occurring malignant tumor with a high rate of recurrence in the case of incomplete excision. This tumor has two characteristics. First, recurrences of pilomatrical carcinoma are common; second, distant metastasis is rare, but if it occurs, it is very fatal. It has characteristic features of high mitotic counts, cellular atypia, and local invasion. Although fine needle aspiration and excisional biopsy could help to confirm this tumor diagnosis, pathologic findings are critical. Pilomatricomas have some characteristic features in histological aspect, such as epithelial islands of basaloid cells and shadow cells or ghost cell. Also, various types of immunohistochemical staining are used to confirm the diagnosis. Despite the lack of clear surgical criteria, treatment is a wide local excision with histologically clear resection margins with or without adjuvant radiotherapy.

This report documents the clinical k pathologic features of 33 patients treated for thymoma for 11 years & 6 months between September 1977 and February 1989. At the Thoracic & Cardiovascular Surgery, Yonsei University, College of Medicine of the group, 31 patients treated with surgery were examined for the result of operation & prognosis. Mean age was 50 years. Thirteen were female and twenty were male. Dyspnea on exertion and chest discomfort were common in the patients without myasthenia gravis. Fourteen patients[42.6%] had myasthenia gravis and one patient had autoimmune thyroid disease. Four patients[12.1%] presented without symptoms attributable to their thymoma. Histologic review disclosed 12[36.4%] epithelial thymoma, 10[30.3%] mixed lymphoepithelial, 9[27.3%] lymphocytic, 1[3.0%] spindle cell and 1[3.0%] unknown cell thymoma. They were classified according to Masaoka`s clinical staging criteria; by these criteria, 8 patients were stage I, 5 patients were stage II, 15 patients were stage III and 3 patients were stage IV. Total excision of mass was possible in 20 patients. Partial excision of mass in 4 patients and biopsy in 7 patients were carried out during the operation. There was only one operation mortality. Follow-up was possible in 26 patients and follow-up ranged from 4 months to 10.5 years[mean 28.9 months]. One-year survival rates were 77.8% and eight patients expired during follow-up period. Eleven[78.6%] patients with myasthenia gravis were improved after the operation. This observation suggests that the most significant factor determining the survival is whether or not total surgical excision had been performed.

Leiomyosarcoma is a rare form of soft tissue neoplasm, with only 1% to 5% occurring in the head and neck region. Current recommended treatment suggests surgical excision with a wide lateral margin, but no definite guidelines regarding excisional margin have been established yet. Recently, complete excision with a narrow surgical margin has been recommended, and the authors present a case of cutaneous leiomyosarcoma on the face that was successfully managed by complete removal with a narrow excisional margin. A 74-year-old woman presented with a 3 cm sized, rapidly growing cutaneous mass on her right preauricular area. Preoperative biopsy of the skin lesion suggested a cutaneous leiomyosarcoma. The authors performed complete surgical excision with a 1 cm lateral margin, and the resulting skin defect was repaired with bilateral V-Y advancement local flaps. Histopathology and immunohistochemistry evaluation confirmed a moderately differentiated cutaneous leiomyosarcoma, with negative margin involvement. The patient refused of any additional treatment, but showed no locoregional recurrence during the 1.5 years of postoperative follow-up period. With a regular postoperative follow-up, cutaneous leiomyosarcomas may be successfully treated with a narrow surgical margin.
