Lipomas are benign mesenchymal tumours derived from mature adipose tissue. It is very rare to see a giant size of lipomas. A 70 year old male patient applied with an ulcerated and painful mass sizing 20x16 cm on his axilla extending to his back. The mass was suspected as a malignant soft tissue tumour because of showing ulceration and being painful and it was totally excised surgically. The histopathological examination revealed as lipoma. The case was presented as being very rare and mixing malignant soft tissue tumour.

Purpose: In this study, contrubitions of computed tomography (CT) and magnetic resonance imaging (MRI) were researched in the diagnosis of benign paranasal sinüs (PNS) lesions. Materials and methods: According to the clinical findings, between January 2001 – February 2004, 30 cases have been studied who were thought to have benign lesions belonging to nasal cavity, PNS or neighboring structures. CT and MRI studies are made to the all case. Inner structure characteristics, locations and radiological apperarances coursing pathological diagnosis of lesions in CT and MRI have been assessed. Results: The histopathological diagnoses of lesions were mucocele (8), odontogenic cysts (4), fibrous dysplasia (3), inverted papilloma (2), hemangioma (2), menengioma (2), schwannoma, osteoma, osteochondroma, paget disease, ameloblastom, giant cell tumor, central giant cell granuloma. Whwn assessed according to pathological results, sensitivity of CT and MRI were found to be 86.6% and 83.3% respectively. In 3 cases showing radiological malign feature (1 giant cell tumor, 2 inverted papillomas) the correct diagnosis was made histopathologically. Canclusion: CT is an effective method to show bone expansion and destructions, tumors originated from bone and intratumoral calcifications. MRI offers better the inner structures of cystic lesions, intratumoral hemorhages and differentiation of tumor from inflammation. Therefore, CT and MRI should be used jointly in the evaluation of the PNS lesions.

Sialolipom is a rare benign tumor, defined as the variant of intraoral lipoma. Tumour is completely surrounded by thin fibrous capsule and consisted of mature adipocytes and normal salivary gland tissue. In here, we present a 55 years old female patient with submandibular gland located sialolipoma.

Lipomas are benign mesenchymal neoplasm commonly occurring throughout the whole body and comprise mature fat tissue. However, intestinal mesentery originated lipomas are rarely seen. A 42-yearold female patient presented with right sided abdominal distension. Exploratory laparotomy was performed and fat tissue was excised. Lipomas might or might not present with any symptoms. Complete surgical excision is the only treatment with a very good prognosis.

Neurogenic tumors ocur at all part of the body but most common site is the posterior mediastinum in thorax. In this study, the patients with neurogenic tumor were evaluated clinical and radiological signs in our hospital between January 1999 and December 2003. Of thirty patients were (11 male and 19 female) their range aged from 20 to 70 mean 41.7±11.8. Histological types were 17 (%57) neurofibromas. 7(23%) schwannomas, 4(13%) ganglioneurinomas, 2(7%) malign schwannomas. Twenty-four (80%) of neurogenic tumors were in posterior mediastinum and the others were in different areas in thorax.

AIM: Kaposi sarcoma (KS) is a vascular proliferative disease associated with human herpesvirus-8 (HHV-8). The studies about the epidemiology of KS in Turkey are limited. We aimed to evaluate the clinical, pathological, and immunohistochemical features a total of 78 KS patients, presenting them along with the available information in the literature.

MATERIALS AND METHODS: We retrospectively evaluated the clinical and histopathological characteristics of a total of 78 patients with KS.

RESULTS: The age of the patients ranged from 46 to 93 years and the mean age was 74.06 years. Of the patients, 59 were males and 19 were females. The lesions were most commonly found on the lower extremities. In the study patients, KS was found both at earlier stages with patches or plaques in 54 of the patients and at the nodular stage in 24 patients. A punch biopsy or an excisional biopsy was performed in 23 and 55 patients, respectively. In the excisional biopsies, the smallest tumor diameter was 0.35 cm and the largest one was 2.8 cm with a mean diameter of 0.98 cm.

DISCUSSION: This retrospective study demonstrated that; in Konya, KS developed in older people and it was most commonly seen in males. It was observed that the demographic features and histopathological types of KS in the study patients were similar to the reports in the literature.

Schwannoma is a benign, solitary, and slowly progressive encapsulated tumor originating from the sheath of myelinated nerve fibers. The neoplasm should arise from all the peripheric, spinal or cranial nerves and frequently seen in the head and neck region. A 33 years-old male presented with a 10x10x6 cms giant mass of the right neck. A surgical resection was performed and the histopathologic examination of the mass was reported to be “schwannoma”. Here, a case of giant schwannoma, which is very rare in the literature, and treatment modalities are discussed.

Lipomas are the most common extratesticular scrotal neoplasms and they most often originate from the spermatic cord. The etiology is unknown but linked to a constitutional factors, obesity, an its presentation is more frequent in the sixth or fifth decade. In this case, an unusual massive scrotal lipoma that occured in 70 years old man is described.

Aim: Lipoma arborescens is a rare intra-articular disease whose etiopatogenesis remains unknown.It was the aim to describe the radiological findings and to discuss the differential diagnosis. Case Report: Lipoma arborescens is a lesion characterized by the replacement of the subsynovial tissue by fat cells giving rise to a villous proliferation. It commonly affects the knee. Accurate diagnosis is important for surgical treatment. A 34-year-old patient who was suffering from a pain in his knee joint was examined by convansional radiography, computerized tomography, and magnetic resonance imaging. The lesion was diagnosed as lipoma arborescens especially with magnetic resonance imaging. Conclusion: The characteristic MR features of lipoma arborescens which has nonspecific clinical findings allows an accurate diagnosis.

in this manuscript a cervical vagal schwannomo is reported. Von Reckiirzklıausen disease was associated to the schwannoma. The relationship between two entilles is discussed. The imporiance of the vagal schwannoma in the dillerantial diagnosis of the head-neck massed rs impressed and the pertinent literature reviewed.

In contrast to the common knowledge on the tethered cord synd•ome, various reports note that co-nus medullaris may have a normal location. In this manuscript a case of tethered cord syndrorrıe which has a conus at Lı level and fatty filum terminale has been presented and liwrature is reviwed.
