Comparison of Histopathological Findings in Psoriasis According to the Lesion Location From Biopsy.

The aim of this study was to investigate whether the histopathological findings of psoriasis varied by the biopsied lesion location. Age, gender, age at disease onset, lesion locations, presence or absence of a preliminary diagnosis of psoriasis, and histopathological findings of 307 patients were recorded. The sections prepared from the patients' paraffin blocks were reexamined microscopically, the severity of the observed findings was graded, and various histopathological features were recorded.

The efficacy of diffusion weighted imaging and apparent diffusion coefficients mapping for liver metastasis of colonic adenocarcinomas.

Objectives: To establish retrospectively the relation between the histopathologic grade of colorectal liver metastasis and apparent diffusion coefficient (ADC) values of hepatic metastases of colorectal adenocarcinomas.

Methods: The diagnoses of liver metastases were confirmed with biopsy, surgery, and follow-up imaging findings. Twenty-six patients with 94 liver metastasis were included in the study.

Mallory-Denk bodies: Correlation with steatosis, severity, zonal distribution, and identification with ubiquitin.

Background/aims: Intermediate filament proteins contain few aggregates as their main component. Among those, Mallory-Denk bodies (MDBs) are by far the best recognized component. To identify the presence of MDBs in individuals having chronic liver disease and to evaluate the correlation among MDBs and steatosis as well as the severity and zonal distribution of hepatocyte balloon degeneration.

Massive Skull Base Ameloblastic Carcinoma with Intracranial Extension.

Ameloblastic carcinoma (AC) is a rare and aggressive malignant epithelial odontogenic tumor that may arise either from the mandible (66.6%) or the maxilla (33.3%).

What is gastritis? What is gastropathy? How is it classified?

Stomach endoscopic biopsies are made to determine the diagnosis of the illness, its stage, and follow-up after the treatment. It is very significant to collaborate with the clinician while evaluating endoscopic biopsies. Besides the clinical and laboratory information of the patient, the endoscopic appearance of the lesion should be known.

[Cervical lymphadenopathy: progressive transformation of germinal centers].

Enlarged lymph node in the head and neck region is a common reason for referral to ear nose throat specialists. In the differential diagnosis of chronic lymphadenopathies, infection, lymphoproliferative disorders and progressive transformation of germinal centers should be considered. In this article, we report two cases of progressive transformation of germinal centers in the neck.

The diagnostic value of non-invasive tests for the evaluation of liver fibrosis in chronic hepatitis B patients.

Background: Liver biopsy, which is considered the gold standard for the evaluation of hepatic fibrosis in patients with chronic hepatitis B (CHB), has certain limitations. The aim of this study was to investigate the diagnostic performance of non-invasive markers of hepatic fibrosis as potential alternatives to liver biopsy.

Methods: The medical records of 221 patients with a diagnosis of CHB who underwent a liver biopsy were reviewed.

Acquired reactive perforating collagenosis.

Acquired reactive perforating collagenosis (ARPC) is commonly recognized as an unusual skin reaction to superficial trauma that is observed in patients with a certain genetic predisposition or underlying diseases, such as diabetes mellitus or renal diseases. We present the unusual case of a 55-year-old female diabetic patient with numerous characteristic dome-shaped nodules, which consisted of central umbilication containing firm keratotic plugs.

Understanding mechanisms of the pathogenesis of nonalcoholic fatty liver disease.

A central issue in the understanding of the pathogenesis of nonalcoholic fatty liver disease is the problem of the underlying mechanisms which are not fully understood. In the setting of excessive central adiposity, insulin resistance is the major underlying cause of fat accumulation in hepatocytes. Because of the difficulties with human trials, several animal models have been developed for this purpose mainly characterized as follows: genetically disturbed or murine fatty liver, methionine-choline deficient diet fed or murine steatohepatitis, and high-fat or sucrose diet fed models.

Gastric ulcer penetrating to liver diagnosed by endoscopic biopsy.

Liver penetration is a rare but serious complication of peptic ulcer disease. Usually the diagnosis is made by operation or autopsy. Clinical and laboratory data were no specific.
