Item Solitary purpuric plaque in a four-year-old girl: Histopathological diagnostic challenge(2022) Uysal, Pinar Incel; Ayvali, Ebru Sebnem; Tepeoglu, Merih; Uysal, Ahmet Cagri; 35593288Item Adult Still's disease: An unusual case with atypical skin and histopathological findings(2020) Vural, Ayse Tuncer; Ozcan, Deren; Tepeoglu, Merih; 0000-0002-9894-8005; AAK-5222-2021Adult Still's disease is a rare, acute systemic inflammatory disease characterized by a sudden rising fever, arthralgia/arthritis, neutrophilic leukocytosis and a typical salmon-colored macular or maculopapular rash associated elevated fever. Recently, atypical skin lesions with broad spectrum clinical features and distinctive histopathological findings have been reported in a rare case with active disease. Herein, we report an unusual case of Adult Still disease was presented and the characteristic features of atypical disease were highlighted.Item Role of Vascular Endothelial Growth Factor in Clinically Localized Prostate Cancer Treated with Radiation Therapy(2014) Erkal, Eda Yirmibesoglu; Bora, Huseyin; Tepeoglu, Merih; Akmansu, MugeBackground: Anti-vascular endothelial growth factor (Anti-VEGF) agents are a promising approach to increase the efficacy of treatment for treatment-resistant prostate cancer. Aims: To correlate vascular endothelial growth factor (VEGF) expression and outcome following radiation therapy in the treatment of clinically localized prostate cancer. Study Design: Retrospective observational study. Methods: Forty-one patients and clinically localized disease that were treated with radiation therapy were analyzed. For VEGF expression, immunoreactivity scores (IRS) were calculated using percent scores and intensity scores. Twenty-four patients were classified as having low (0 to 4 IRS) and 17 patients were classified as having high (5 to 8 IRS) VEGF expression. Results: The median age was 71 years, median follow-up was 5.4 years and median radiation therapy dose was 70 Gy. VEGF expression was calculated as low in 24 patients and high in 17 patients. Higher VEGF expression was observed in 6/26 patients with a low Gleason score versus 11/15 patients with a high Gleason score (p=0.02). Biochemical failure (BF) was observed in 2/24 patients with low VEGF expression versus 7/17 patients with high VEGF expression (p=0.01). In univariate analysis, having a higher Gleason score (p<0.01), being in the high risk group (p=0.03) and having higher VEGF expression (p=0.01) predicted BF after definitive radiation therapy. The biochemical failure-free survival rate at 5 years tended to be different (91% vs. 53%) when patients were grouped according to VEGF expression (p=0.06). Conclusion: In attempt to define patients with clinically localized disease that are not sensitive to standard treatment modalities, cellular and/or molecular biological markers may be requiredItem Chondromyxoid Fibroma of the Sternum in a 63-Year-Old Woman(2015) Kilic, Dalokay; Findikcioglu, Alper; Tepeoglu, Merih; Vural, Cigdem; 26413029Primary chondromyxoid fibroma is a benign bone tumor. Its localization in the sternum is quite rare; we found only 6 relevant reports. We report our diagnosis and treatment of a chondromyxoid fibroma in the sternum of a 63-year-old woman. The patient underwent subtotal sternectomy and chest-wall reconstruction with use of a titanium rib bridge system and Prolene mesh. The patient's clinical course was uneventful, and she had no local recurrence 41 months postoperatively. Our review herein of the 6 previous cases reveals that our patient is the oldest thus far to have been diagnosed with a sternal chondromyxoid fibroma.Item An unusual eyelid mass: Tarsal dermoid cyst(2015) Sezenoz, Almila Sarigul; Arat, Yonca Ozkan; Tepeoglu, Merih; 26586987We report the case of a 15-month-old boy who presented with a mass lesion of the right upper eyelid that had been present since birth and had slowly enlarged over the last 3 months. The lesion had minimal surrounding erythema simulating the appearance of a chalazion. Intraoperatively the lesion was noted to be firmly adherent to the underlying tarsus. The lesion was excised completely through an eyelid crease approach leaving the tarsus intact. The histopathology was consistent with dermoid cyst. To our knowledge, this is the third case of a tarsal dermoid cyst reported in the literature. Dermoid cyst should be included in the differential diagnosis of eyelid mass lesions, and particulary differentiated from a chalazion to avoid mismanagement that may lead to scarring, recurrence and inflammation. The excision of these lesions sparing the underlying tarsus can be possible.Item Biphasic Pulmonary Blastoma Associated with Cerebral Metastasis(2016) Kilic, Dalokay; Yilmaz, Cem; Tepeoglu, Merih; Vural, Cigdem; Caner, Hakan; 26768884Pulmonary blastoma is a very rare malignant tumor of the lungs. A biphasic pulmonary blastoma was histologically diagnosed by a characteristic finding as it was mainly constituted of immature tumor tissue that had both epithelial and mesenchymal components. We present a case of a 68-year-old man with biphasic pulmonary blastoma. The patient underwent cranial metastatectomy and left lung upper lobectomy. Although the tumor was resected, there was rapid metastasis to the cranial, liver, kidney and multiple bones. Although radiotherapy and chemotherapy were administrated, the patient died about 6 months postoperatively. Close follow-up and aggressive chemotherapy should be considered for such tumours. In the light of this case, the authors review the pathologic, clinical, radiological and therapeutic features of this very rare malignant lung tumor.Item A Case of Two Synchronous Cutaneous Collision Tumors(2017) Ayva, Sebnem Kupana; Tepeoglu, Merih; Gunduz, Ozgur; Yazici, Ilker; Bozbogan, Onder; 0000-0002-9894-8005; 0000-0002-2280-8778; AAK-5222-2021; AAK-1967-2021Cutaneous collision tumors are known as two independent tumors which are close anatomically and separated from one another by well boundaries. We, herein report a 83-year-old female patient with two cutaneous collision tumors in two different localizations at the same time. First cutaneous collision tumor located on left ala nasi was squamous cell carcinoma and basal cell carcinoma and second one located on the right commisure was composed of malignant melanoma (Clark Level IV) and basal cell carcinoma. However, the presence of collision tumors is not uncommon and is often reported in the literature, to the best of our knowledge, it is the first case which shows the association of two synchronous cutaneous collision tumor in the same individual.Item Cloacogenic Adenocarcinoma of the Vulva: A Case Report and Review of the Literature(2018) Tepeoglu, Merih; Uner, Halit; Haberal, Asuman Nihan; Ozen, Ozlem; Kuscu, Esra; 28272666Primary adenocarcinoma of the vulva, unrelated to the native glands of perineum is an extremely rare neoplasm. Despite awareness of this lesion for over 40 years, the origin is not beyond speculation. The most reasonable hypothesis is based on the remnants of cloacal differentiation during early days of life. Here we report the case of a 60-year-old patient with a vulvar mass, who underwent partial vulvectomy and bilateral regional lymph node dissection. The tumor was composed of papillary and complex glandular structures and exhibited diffuse positivity for cytokeratin 20 and polyclonal CEA, CDX2, and focal positivity with cytokeratin 7. Unlike the indolent behavior of this malignant neoplasm according to the literature, we found two metastatic inguinal lymph nodes. She did not receive adjuvant therapy and is still alive, free of disease 38 months after surgery. We present different aspects of vulvar adenocarcinomas with a case report.Item A rare case of a gastric adenomyoma mimicking a gastric duplication cyst(2018) Arslan, Esra Elif; Demir, Tugba Acer; Guney, Lutfi Hakan; Tepeoglu, Merih; Akilli, Muge Sagnak; Hicsonmez, Akgun; 30260786
