Intraosseous lipoma is one of the rarest primary benign tumors of bone and it is characterised by a neoplastic overgrowth of univacuolar fat cells. The incidence is less than one per 1,000 bone tumors. Most commonly, long bones are affected, with a tendency for metaphyseal involvement. Because of its rarity and nonspecific clinicopathologic findings, biopsy is needed for accurate diagnosis. Currettage and bone-grafting is the treatment of choice if the lesion is painful or if structural stability is threatened. We report 3 cases of intraosseous lipoma in long tubular bones with review of literatures. Two cases were treated by surgical intervention and the other case by conservative management.

The presence of accessory scrotum is a condition characterized by additional scrotal tissue with a normally developed scrotum. The condition is extremely rare and can be associated with a perineal lipoma. Herein, a case of accessory scrotum associated with a perineal lipoma is reported in a 4-day-old boy. He presented with a perineal mass and the diagnosis was confirmed by surgical excision and subsequent histological analysis. This is the first Korean report of an accessory scrotum associated with perineal lipoma. (Korean J Urol 2007;48:1096-1098)

Endobronchial lipomas are rare lesions that usually obstruct a major bronchus and cause irreversible pulmonary damage distally. They are histologically benign tumors. But they can produce pulmonary damage or irreversible bronchiectasis if dignoses or treatments are delayed. Whenever possible, the treatment of choice is resection by means of bronchoscopy. If endoscopic removal is not possible or if the nature of the tumor is unclear, surgery is necessary, with lobectomy or pneumonectomy being required in most cases due to the extensively damaged pulmonary parenchyma. We present a case of endobronchial lipoma causing bronchial obstruction and peripheral organizing pneumonia with its clinical features, diagnosis and treatment methods.

Gastric lipomas are rare benign submucosal tumors which can present the diagnostic and therapeutic problems. The preferred treattment is observation or local excision. Since preoperative diagnosis and differentation from malignant tumors can be difficult by use of the conventional diagnostic modalities such as X-ray or endoscopic examination, patients are sometimes subjected to more extensive surgical procedures than warranted. As to the diagnosis of submucosal tumors of the upper digestive tract, a newly developed diagnostic modality of endoscopic ultrasonography(EUS) allows us to visuialize the structures underlying the gastrointestinal wall in a noninvasive maneuver, and can contribute to make differential diagnosis and decision of management. Strip biopsy is an endascopic tissue resection technique which permits resection of both mucosal and submucosal tissue regardless of the morphological type of the lesion, because the submucosal saline injections during the procedures make the flat or depressed lesions to be elevated. Now, we report a 56-yr-old female which had a Yamada type I polypoid gastric submucosal lipoma in the antrum, which could be performed the different diagnosis and successful endoscopic removal by endoscopic ultrasonography and strip biopsy.

In this paper I report two cases of subconjunctival lipoma in a 16 years old female and in a 12 years old male. The diagnosis was made on the basis of clinical and histopathological findings. Histopathologically the lipoma was composed of several groups of mature fat cells separated from other groups by delicate fibrovascular septae. Lipoma is a benign tumor occurring frequently in the orbit, but they were very large in size and in case 2 the mass had spreaded over the both tarsal conjunctiva and retrobulbar spaces which wasJmpossible to be removed completely.

PURPOSE: To diagnose soft tissue tumor, such as lipoma and Schwannoma, magnetic resonance imaging (MRI) is sufficient in most cases. However, various characteristics are found in MRI images of Schwannoma, thus other type of tumors are often misdiagnosed as Schwannoma with MRI images. In this study, we evaluate the diagnostic value of specific MRI findings of Schwannoma. MATERIALS AND METHODS: From January 2002 to May 2013, 104 patients who are suspected as Schwannoma rith MRI images are included in data, and the final diagnosis is confirmed with biopsy. Patients are divided into group 1 and group 2 who are confirmed as Schwannoma and other disease with biopsy, respectively. RESULTS: 92 patients were diagnosed as Schwannoma (group 1) and 12 patients were diagnosed as other disease (group 2). We investigate the diagnostic value of specific MRI findings of Schwannoma. 41 patients of group 1 (45%) and 0 patients of group 2 (0%) showed target sign, 47 patients of group 1 (51%) and 2 patients of group 2 (17%) showed fascicular sign, 44 patients of group 1 (48%) and 5 patients of group 2 (42%) showed fat split sign, 28 patients of group 1 (30%) and 1 patients of group 2(9%) showed nerve entering and exiting sign, and 8 patients of group 1 (9%) and 6 patients of group 2 (50%) showed none of four specific findings on their MRI images. 52 patients of group 1 (57%) and 5 patients of group 2 (42%) have tumors on the pathway of nerve. Target sign could be considered as the best diagnostic value of the sign we investigate (p<0.05). CONCLUSION: Although specific MRI findings have powerful diagnostic value, patients are often misdiagnosed as Schwannoma with MRI findings. Therefore, if patients who are suspected as Schwannoma based on MRI findings have no target sign on their MRI images, we should consider the possibility of other disease.

We have experienced 4 cases which were clinically diagncsed as granuloma pyogenicum, but histologically as a malignant melanorna, an eccrine angiomatous hamartoma with granuloma pyogenicum, a subungual exostosis, and a lipoma, with granulation tissue. A granuloma pyogenicum may have clinical resemblances to various benign or malignant lesions. Therefore, any lesion that resembles a granuloma pyogenicum should have this clinical impression confirmed by histologic examination.

Parosteal lipoma is a rare benign lipomatous neoplasm and found in close or direct apposition to bone, most commonly in the extremities. In the forehead, it is called subgaleal lipoma because of the location between the galea and the periosteum of the frontal bone. Clinically it presents as a round to oval, smooth, firm and relatively fixed, flat or dome shaped mass, unlike the usual lipoma. A parosteal lipoma in the forehead tends to be misdiagnosed initially as other superficial lesions such as epidermal cyst. Therefore, clinical recognition of the tumor and its location is important preoperatively so that the incision is deep enough to find the lesion and to make the correct diagnosis of most firm forehead masses.

Primary tracheal tumors, especially lipoma, are very rare. Symptoms of tracheal tumor mimic common upper airway diseases. It is important that they may initially be misdiagnosi4 to bronchial asthma, chronic bronchitis, resulting in a delay in diagnosis. We report a case of tracheal lipoma who was found 6 months after first noticing symptoms including dyspnea, foreign body sensation, successfully removed by bronchoscopic polypectomy.

Lipoleiomyomas of the uterus are extremely rare benign neoplasm that can be difficult to differentiate from benign cystic ovarian teratomas. Only a few pure lipomas of the uterus have been documented. We presented a case of lipoleiomyoma of the uterus, in which sonography and computed tomography were per formed, but because of its rarity, and confusion with more common uterine leiomyoma and ovarian dermoid tumor, preoperative diagnosis was not suggested. To our best knowledge, this is the first case of uterine lipoleiomyoma in Korea.
