  • So-called sclerosing hemangioma of the lung is a rare benign neoplasm of uncertain histiogenesis, with a complex but characteristic histologic appearance. We experienced a typical lesion of pulmonary sclerosing hemangioma clinically and histologically, which was removed from the right lower lobe of 22-year-old male and was reviewed by Darryl Carter at Yale University. We discussed histiogenesis, microscopic features and prognosis of the sclerosing hemangioma.

  • Calcifying fibrous pseudotumors are rare soft-tissue lesions pathologically characterized by hyalinized collagen, psam-momatous or dystrophic calcification, and lympho-plasmacyte infiltration. They are clinically benign with an extremely low rate of recurrence and complete surgical resection is known to be the treatment of choice. We performed the resection of a calcifying fibrous pseudotumors in the anterior mediastinum without complications.

  • mediastinal teratomas are encountered commonly in adult life, and rarely in childhood. Characteristically, these mediastinal teratomas are located anteriorly with only rare examples in the posterior mediastinum. The cystic teratoma usually behaves as a benign neoplasm, but the solid [non-cystic] teratoma is frequently malignant. We experienced a case of large anterior mediastinal cystic teratoma in a two-years old boy, which was treated by complete surgical excision with good result.

  • The glomus tumor is a distinctive benign neoplasm, the cells of which resemble the modified smooth muscle cells of the normal glomus body. This tumor occurs most frequently in the extremities but may find elsewhere in the body. Only one case of mediastinal glomus tumor has been reported in the world. Recently we experienced a case of mediastinal glomus tumor managed with surgical removal and followed up without any significant complications for 17 months.

  • The true cementoma (attached cementoma) is an unusual benign jaw neoplasm fused to the root of the involved tooth. The authors have treated a true cementoma occurs at the right mandibular first molar. The 26 years old male patient who has complained of sweeling and discomfort of the involved tooth. The radiograph showed that the tumor represents a dense radiopacity bordered by a well demarcated peripheral radiolucent zone. Treatment was performed by extraction of the involved tooth with complete enucleation of the tumor. So the operation was done without any complications.

  • Schwannoma(neurilemmoma) is a benign neoplasm that originates from the Schwann cells. Schwannoma most commonly arises in the soft tissue of the head and neck. Intraoral lesions are uncommon, however, and intraosseous schwannoma are even rare. The most common site of occurrence for these unusual lesions is the mandible. This article documents a case of an intraosseous schwannoma located in the mandibular ascending ramus. The lesion was surgically removed and no radiographic evidence of recurrence was observed after 1 year.

  • Leiomyoma is extremely rare benign tumor of the trachea. A case of leiomyoma of the trachea is described in a 36-year-old man. The patient had a brief history of asthma-like symptoms. Computed tomography of the chest revealed the ovoid lower trachea mass, which was occupying about 80% of the tracheal lumen. At fiberoptic bronchoscopy highly vascularized round mass was seen on the membranous portion of the lower trachea. The tumor was excised by segmental sleeve resection and end-to-end anastomosis of the trachea was performed. Postoperative course was uneventful and bronchoscopic findings showed clear healing of the anastomotic site.

  • The central odontogenic fibroma is a rare benign neoplasm, and considered to be derived from the mesenchymal tissue of dental origin. It is a poorly defined tumor of the jawbones which has only been infrequently reported in the literature. We report a histologically proven case of simple-type central odontogenic fibroma, which affected the left canine-premolar region of the maxilla in a 52-year-old woman.

  • We have experienced a case of primary thymic carcinoma. A 39 year old female patient admitted with incidentally detected mediastinal mass on chest film.The tumor showed invasion to surrounding tissues and the mediastinal lymphadenopathies were also noted. Invasion to contiguous mediastinal structures made complete surgical extirplation impossible and the biposy findings revealed primary thymic carcinoma. Primary thymic carcinoma is a rare neoplasm originating from the thymic epithelial cells. Clinical behavior of the thymic carcinoma is much different from it`s benign counterpart and several pathologic variants were reported.

  • Chondroblastoma is a rare benign cartilaginous neoplasm that accounts for 1% of bone tumors and is common in the epiphysis of the long bones. The condition is rarely found in the talus bone (4% of cases). This paper reports a 15-year-old male patient treated for a talus bone lesion discovered incidentally on imaging. Excisional biopsy, curettage, and an autobone and allobone graft were performed, with good results.
