    Cholesterol granuloma of the maxillary sinus
    (Ethiopian Med Assn, 2004) Alper, Murat; Belenli, Olcay Kandemir; Aksoy, Kamuran Aylin; Suna, Mazlume; Çukur, Selma
    Cholesterol granuloma is usually associated with middle ear disease and is very rare in the paranasal sinuses. We report a case of cholesterol granuloma originating in the maxillary sinus of a 36-year-old female. Endoscopic sinus surgery was performed on the left maxillary sinus, and the cholesterol granuloma was successfully removed by the middle meatal antrostomy.

    General features of gastric carcinomas and comparison of HSP70 and NK cell immunoreactivity with prognostic factors
    (2002) Canöz, Özlem M.; Belenli, Olcay Kandemir; Patıroǧlu, Tahir Ercan
    During the period of 1996-1998 ninety-four gastrectomy specimens with gastric carcinoma referred to Erciyes University, Medical Faculty, Department of Pathology, were examined histopathologically, histochemically and immunohistochemically. General characteristics of gastric carcinomas and prognostic factors were studied. According the Lauren classification, of the 94 cases of gastric carcinomas, 56 were intestinal type, 21 were diffuse type and 17 were mixed type carcinoma. The association rates of Helicobacter pylori, chronic atrophic gastritis and intestinal metaplasia with gastric carcinomas were high. There was strong immunorectivity with HSP70 in 62,5% of the intestinal type carcinomas. This ratios were lower in diffuse and mixed type carcinomas (p<0.05). The more tumor size and invision depth increased, the more HSP70 immunoreactivity was obtained (p<0.05). HSP70 immunorectivity was considerably higher in the patients having lymph node metastasis and vascular invasion (p<0.05). It was found that the NK cell number was low in the tumor but higher around the tumor in early gastric carcinomas, compared with advanced carcinomas (p>0.05). In the tumors larger than 10 cm with vascular invasion, NK cell number was lower around the tumor (p>0.05). Defining prognostic factors of gastric carcinomas is of importance to clinicians. It is thought that HSP70 immunoreactivity, besides invasion depth, lymph node metastasis, vascular invasion, tumor size and inflammatory reaction against the tumor, is important in prognosis and associated with advanced stage.

    Micropneumatosis coexistent with Helicobacter pylori and its improvement
    (2003) Belenli, Olcay Kandemir; Akçan, Yusuf; Alper, Murat
    Micropneumatosis intestinalis is the occurrence of gas-filled circular voids with diameter of 20-200 microns, not lined with epithelium. We report a 39-year-old man with superficial gastritis and Helicobacter pylori infection who also had gastric, duodenal and colonic micropneumatosis. Endoscopic biopsy after treatment for H. pylori gastritis showed no micropneumatosis in gastric, duodenal or colonic mucosal sections. We suggest that H. pylori may be one of the causative factors for micropneumatosis.

    Morgagni cyst within tubal lipoma
    (2005) Alper, Murat; Aksoy, Kamuran Aylin; Somunkıran, Aslı; Belenli, Olcay Kandemir
    Both benign and malignant tumors of the fallopian tube are uncommon. Benign tumors are most often of mesodermal origin and usually are small enough to be incidental findings at laparotomy. We describe a fallopian tube lipoma that inserted a morgagni hydatid cyst in a 48 year old woman.

    Subepidermal calcified nodule
    (Univ West Indies Faculty Medical Sciences, 2003) Alper, Murat; Parlak, Ali Haydar; Belenli, Olcay Kandemir
    Subepidermal calcified nodules are rarely seen and are classified under, idiopathic subepidermal calcifications. They commonly affect children. It is most frequently encountered in the face, and it is less common in the extremities. Here, we-present a case where the lesion was, localized on the knees of a 23-year-old female patient.
