Distribution and Expression of the Adhesion Molecule CD44 on Human Corneal Grafts Is Not Altered by Chemotherapy.

Background/aim: Acceptance of corneas from donors with a malignancy remains controversial, especially for donors with hematological malignancy. The aim of our study was to examine, for the first time in literature, any structural differences in the integrity of the corneal grafts from donors who have received and from those who have not received chemotherapy.

Materials And Methods: The immunohistochemical expression of CD44 was examined in 12 corneal grafts obtained from 8 donors.

Correlation of Glycosylated Hemoglobin Levels with Histological and Ultrasound Characteristics of the Carotid Plaque in Diabetic and Nondiabetic Patients.

Background: The purpose of this study is to investigate the correlation of glycosylated hemoglobin (HbA1c) levels with histological characters of atherosclerotic plaque that makes it vulnerable, as well as ultrasound (US) criteria that can contribute to the prognosis of carotid disease.

Material And Methods: This is a single-center prospective study. Our study population consists of 74 diabetic and nondiabetic patients with carotid atherosclerosis who underwent carotid endarterectomy in our department.

Chondrosarcoma of the proximal phalanx of the fourth digit: a rare location.

Introduction: Cartilaginous tumors involving the small bones of the hands and feet are usually benign such as enchondroma, chondromyxoid fibroma and chondroblastoma. The small bones of the hands and feet are rarely involved by primary chondrosarcoma. Proximal phalanges are the most common sites in the hands, but the fourth digit is the least common site.

Gastric calcifying fibrous tumor: a very rare case report.

Calcifying fibrous tumor is a very rare benign mesenchymal tumor which shows a predilection for soft tissue, mesentery and peritoneum. Up to date only 7 cases have been reported in the literature confined to the gastric wall. We report a rare case of a calcifying fibrous tumor of the stomach in a 60-year-old man who presented with dyspepsia, flatulence and feeling weight.

Synchronous primary adenocarcinoma and ancient schwannoma in the colon: an unusual case report.

Gastrointestinal schwannomas are uncommon stromal tumors of the intestinal tract and colon schwannomas are extremely rare. We report a rare case of ascending colon schwannoma with associated synchronous adenocarcinoma of the sigmoid colon. A 68-year-old man presented with a 20-day history of bleeding per rectum.

Borderline clear cell adenofibroma of the ovary associated with ovarian endometriosis: a case report.

Clear cell tumours of the ovary are relatively uncommon. Most of them are clear cell carcinomas. Benign and borderline clear cell tumours are extremely rare and almost always fibromatous.

Primary cutaneous apocrine carcinoma of sweat glands: a rare case report.

Cutaneous apocrine gland carcinoma, a subtype of sweat gland carcinoma, is a very rare malignancy, and only few cases have been reported in the literature. Many of these carcinomas are indolent and slowly developing, but some are rapidly progressive. The treatment of choice is wide local excision with clear margins, with or without lymph node dissection.

An unusual case of unilateral malignant leydig cell tumour of the testis.

Leydig cell tumour is a benign testicular non-germ cell tumour, and malignant transformation is rare. We report a case of a 35-year-old man who came to our hospital with a painless left testicular mass measuring 1.2 × 1 cm.

Extraovarian peritoneal serous papillary carcinoma: a case report.

Background: Extraovarian peritoneal serous papillary carcinoma (EPSPC) is a rare cancer closely related to ovarian carcinoma and characterized by abdominal carcinomatosis without an identifiable abdominal primary tumor.

Case: A woman presented with ascites. She had an elevated serum CA-125.

Interposition of a reversed jejunal segment enhances intestinal adaptation in short bowel syndrome: an experimental study on pigs.

Background: Interposition of a reversed intestinal segment as a factor facilitating intestinal adaptation has been experimentally investigated. Controversy exists about its efficacy in terms of body weight improvement, direction of luminal changes, and underlying mechanisms. This study aims to provide a comprehensive approach.

Primary malignant mixed müillerian tumour of the fallopian tube. Report of a case.

Malignant mixed müllerian tumour of the fallopian tube is an extremely rare lesion and to date only approximately 50 cases have been reported. The tumour is seldom distinguished preoperatively from other more common lesions or ovarian cancer. We report a case of a 60-year-old woman who presented to our hospital with pelvic pain.

Adenosquamous carcinoma of the pancreas: a case report.

Adenosquamous carcinoma of the pancreas is a rare variant of pancreatic exocrine carcinoma. We report a case of 70 year old man who came to our hospital with abdominal pain, anorexia and jaundice. Imaging of the abdomen showed a mass in the region of the head of the pancreas.

Synchronous endometrioid carcinoma of the uterine corpus and ovary. A case report and review of the literature.

Synchronous endometrioid carcinoma of the uterine corpus and ovary is an uncommon but well recognized event. Diagnosis as either a separate independent primary or as a metastatic tumor requires careful consideration of a number of gross and histological features. These features illustrate the criteria helpful in distinguishing independent primaries from metastatic carcinomas which have a different therapeutic implication.

Malignant adenomyoepithelioma of the breast--case report.

Malignant adenomyoepithelioma (MAME) of the breast is a rare tumor characterized on the basis of histologic, immunohistochemical and ultrastructural features by malignant proliferation of the epithelial and myoepithelial cells. We report a case of an 80-year-old woman with malignant adenomyoepithelioma of the breast, one of the oldest patients described up to today. A primary tumor in the left breast grew within a short period of time.

Combined carcinoid and mixed (composite) glandular - endocrine cell carcinoma of the stomach in atrophic gastritis.

We describe a case of gastric carcinoid and inflammatory fibroid polyp concomitant with a composite tumor of the gastric antrum composed of poorly differentiated adenocarcinoma - endocrine carcinoma with immunohistochemical documentation of endocrine and non endocrine differentiation in a 67-year-old man with atrophic gastritis and intestinal metaplasia. When gastrectomy was carried out, two lymph nodes along the greater curvature harbored metastasis from carcinoid. The same occurrence is reported in several cases in the literature, which suggests that the association of gastric carcinoid to adenocarcinoma could point to the malignant nature of carcinoid.

Glomus tumor of the stomach: a case report.

Glomus tumors are relatively uncommon benign neoplasms, most common in the skin and subcutaneous tissue, but can also occur in the viscera, most often in the stomach. Preoperative diagnosis, when the tumor occurs in the stomach, seems difficult but is important, since glomus tumors of the stomach are essentially benign and amenable to conservative excision, contrary to aggressive gastric neoplasms. We describe the case of a 75-year-old man presented to the emergency department with gastrointestinal bleeding and epigastric pain.

Bilateral primary breast lymphoma--case report.

Primary lymphoma of the breast is an uncommon malignant breast tumor which is seldom distinguished preoperatively from other more common forms of breast cancer. Bilateral breast lymphoma affects younger women especially during pregnancy or postpartum. We report a case of a 55-year-old woman who was admitted to our hospital with painless bilateral breast enlargement.
