Lymphangioma is a developmental anomaly that is known to occur in the neck and axilla, and only rarely in the mediastinum, retroperitoneum, groin and pelvis. An isolated chest wall lymphangioma is a rare benign neoplasm. In case of large sized lymphangioma, surgical excision is preferably recommended as the treatment of choice. We operated on a three-year old female for excision of chest wall. In pathologic diagnosis, it diagnosed the mass as chest wall lymphangioma.

Giant lymph node hyperplasia(Castleman's disease) is a rare disease, which represents a peculiar form of lymph node hyperplasia. Generally, it has been considered as benign and localized disease but recently, revealed malignant transformation in some cases of multicenteric form. It usually occurs on the mediastinum and occasionaly neck, lung, axilla, mesentery, broad ligament, retroperitoneum or soft tissue of extremities. Histopathologically, it is divided into hyaline vascular or plasma cell type and the former is characterized with prominent vascular proliferation and hyalinization in the central portion and tight concenteric layering of lymphocytes at the periphery of the fillicles(mantle zone) and the latter is characterized by a diffuse plasma cell proliferation in the interfollicular area. From the point of view of clinical presentation, it has been divided into solitary form, which presents as a localized mass located most commonly in the mediastinum, and multicenteric form, which occurs multiple location and has systemic manifestation arid transformation into malignancy. Herein we report a case of Giant lymph node hyperplasia occuring in the left spermatic cord in a 58-year old male with brief review of literatures.

An arteriovenous fistula (AVF) from the renal artery following a penetrating abdominal trauma is not common. We report the case of a 19-year-old male who presented with a knife stab wound in the right upper quadrant. Due to unstable vital signs and to the protrusion of the mesentery through the stab wound, providing definite evidence of peritoneal violation, an emergent exploratory laparotomy was carried out. There were injuries at the proximal transverse mesocolon and the second portion of the duodenum, with bile leakage. There was also a mild amount of retroperitoneal hematoma near the right kidney, without signs of expansion or pulsation. The mesocolon and the duodenum were repaired. After the operation, abdominal computerized tomography (CT) was performed, which revealed contrast from the right renal artery shunting directly into the vena cava. Transcatheter arterial embolization with a coil and vascular plug was performed, and the fistula was repaired. The patient recovered completely and was discharged without complication. For further and thorough evaluation of an abdominal trauma, especially one involving the retroperitoneum, a CT scan is recommended, when possible, either prior to surgery or after surgery when the patient is stabile. Furthermore, a lateral retroperitoneal hematoma and an AVF after a penetrating trauma may not always require exploration. Sometimes, it may be safely treated non-operatively or with embolization.

Malignant fibrous histiocytoma (MFH) is the most common soft tissue sarcoma of late adult life. This tumor occurs principally as a mass on an extremity or in the abdominal cavity or retroperitoneum of adult but primary pulmonary MFH is rare. MFH may be subclassified into storiform-pleomorphic, myxoid, giant cell, inflammatory, and angiomatoid type and the prognosis is no different among the histologic subtypes. We experienced one patient who was consistent with primary MFH of the lung. The patient complained dyspnea and intermittent hemoptysis and showed bilateral suprahilar mass on simple chest film and chest CT. Histological findings by open lung biopsy was storiform-pleomorphic type and individual cells showed histiocyte-like and fibroblast-like appearance.

Since IgG4-related pancreatitis was first reported in 2001, IgG4-related disease has been identified in other organs such as salivary gland, gallbladder, thyroid, retroperitoneum and kidney; but lung invasion is rare. A 63-year-old man presented with hemoptysis at the pulmonary clinic and chest computed tomography revealed about 4.1 cm irregular shaped mass with spiculated margin at the left upper lobe. Despite no elevation of serum IgG4 level, he was finally diagnosed as IgG4-related lung disease by transthoracic needle biopsy. After treatment with oral glucocorticoids, hemoptysis disappeared and the size of lung mass was decreased.

Paragonimiasis is a parasitic disease caused by Paragnonimus species. The primary site of infection is the lung, and extrapulmonary involvement is also reported. When infected with Paragonimus westermani, which is the dominant species in Korea, the central nervous system is frequently involved along with the liver, intestine, peritoneal cavity, retroperitoneum, and abdominal wall. Ectopic paragonimiasis raises diagnostic challenge since it is uncommon and may be confused with malignancy or other inflammatory diseases. Here, we report an ectopic paragonimiasis case initially presented with recurrent abdominal pain. The patient developed abdominal pain 3 times for the previous 3 years and the computed tomography (CT) of the abdomen revealed fluid collection with wall enhancement. Recurrent diverticulitis was initially suspected and part of the ascending colon was resected. However, the specimen showed intact colon wall without evidence of diverticulitis and multiple parasite eggs and granulomas were found instead. The size of about $70{\mu}m$, the presence of an operculum and relatively thick egg shell suggested eggs of Paragonimus species. With appropriate exposure history and a positive antibody test, the definitive diagnosis was made as peritoneal paragonimiasis.

Primary retroperitoneal mucinous cystadenocarcinoma is a very rare malignancy, and little is known concerning its pathogenesis, optimal treatment, and prognosis. A 29-year-old pregnant woman (21 weeks) presented with abdominal discomfort. CA 19-9, CA 125, and CEA were normal. Abdominal CT scanning revealed a $19{\times}15{\times}13cm$ retroperitoneal tumor. Exploratory laparotomy and tumor excision were performed. Mucinous retroperitoneal implants were removed as completely as possible. Histologically, the tumor showed focal areas of capsular invasion, but free resection margins. The uterus and both ovaries were normal in appearance. No adjuvant therapy was pursued. Six months later, peritoneal and bilateral ovarian metastases were discovered. Hence, we report the details of this case of primary retroperitoneal mucinous cystadenocarcinoma and present a review of the literature.

Purpose: Malignant changes of Marjolin's ulcer arising from chronic burn scar are rare. The majority of them are squamous cell carcinoma and basal cell carcinoma. Malignant fibrous histiocytoma is a deep seated pleomorphic sarcoma, which occurs principally as a mass of the extremities, abdominal cavity, or retroperitoneum in adults. Methods: We report a 58-year-old male patient who was admitted due to $3.5{\times}5cm$ chronic ulceration of anterior chest wall on the center of old burn scar. His scar had been occurred by boiling oil and treated with conservative treatment 45 years ago. Preoperative punch biopsy showed suspicious malignant changes and contrast enhanced chest CT showed well-defined, irregular shape enhancing lesion on anterior chest wall without intrathoracic metastasis. Results: The tumor was widely excised and defect was covered with skin graft without infection, necrosis and any other complication. The pathologic findings are compatible with malignant fibrous histiocytoma(storiform - pleomorphic type). The patient underwent 3 cycles of chemotheraphy. Although distant metastasis to the lung developed 6 months later and the patient died 9 month later, there was no local reoccurrence. Conclusion: Aggressive and early excision is needed because malignant fibrous histiocytoma has characteristics of high malignancy with a propensity for early and distant spread. Furthermore, the patient's education about disease entity and postoperative regular follow-up for local recurrence or metastasis is very important. To prevent malignancy from secondly healing burn scar, early skin graft is recommended for patients with deep second degree burn.

Bronchogenic cysts are usually located in the pulmonary parenchyma or in the mediastinum. When bronchogenic cysts are located in the mediastinum, they are usually near the bronchus or esophagus, and rarely located in the retroperitoneal space. It is difficult to differentiate between bronchogenic cysts and benign cysts prior to surgert. We report here on a patient for who had a mass in the retroperitoneum, with the preoperative diagnosis being a benign neurogenic tumor. Via left open thoracotomy, pathologic reports revealed that the mass was a bronchogenic cyst. We report here on the case of a bronchogenic cyst that was located in the retroperitoneal space of the diaphragm.

Malignant fibrous histiocytoma(MFH) is a deep-seated pleomorphic sarcoma, which occurs principally as a mass of the extremities, abdominal cavity, or retroperitoneum in adults. However, it only rarely occurs in the chest wall. An 85-year-old man had undeergone excision of a small mass on the right posterior chest wall under local anesthesia 14 months age. However, the lesion did not heal and the mass recurred. He was referred to our hospital after the mass had grown to a size of 10.5$\times$8$\times$4cm with a 3$\times$3cm skin defect. Intraoperative frozen biopsy revealed MFH. An en-bloc wide resection and thin-thickness skin graft from his thigh were performed. Although distant metastasis to the lund developed 14 months later and the patient died 2 months later, there was no local recurrence. Thin-thickness skin graft is a simple method for a wide range skin defect, especially in the old age. He recovered in good condition without any physical disabilities.
