OBJECTIVE To analyze the differential diagnosis when keratinized squamous cells are found in a brain aspirate. STUDY DESIGN Twenty cases of brain aspirates with keratinized squamous cells were retrieved (1982-2001). Diagnoses included craniopharyngioma (CP) (n = 11), metastatic squamous cell carcinoma (SCC) (n = 5), epidermoid cyst (EC) (n = 3) and Rathke cleft cyst (RCC) (n = 1). Aspirates w...

Squamous cell carcinoma is a malignant epithelial neoplasm characterized by variable clinical manifestations. When located in the gingiva, this neoplasm may mimic common inflammatory lesions. The aim of this study was to report a case of atypical squamous cell carcinoma. A 60 Year old male patient was presented to the department with complains of pain and ulcer in the upper right back region of...

We studied interobserver variability in the proportions of human papillomavirus (HPV)-positive results for atypical squamous cells of undetermined significance (ASCUS) and atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion (ASC-H) diagnoses among 5 pathologists from the me laboratory during a 2-year period. These proportions were compared with individual patholog...

We examined 170 formalin-fixed paraffin-embedded samples from esophageal squamous cell carcinoma patients. All subjects live in Mazandaran province, a region with high incidence rate of esophageal cancer and have become known as the “Asian Esophageal Cancer Belt”. Samples were tested for HPV-DNA by MY09/11 and Gp5+/6+ general primers using nested PCR. Of the 170 ESCC samples, 86 (50.6%) were ma...

Squamous cell carcinoma of the gallbladder is rare and constitutes only 0.5-3% of all malignancies of this organ. Most of the reported cases have had a component of adenocarcinoma. We report a 70-year-old man who presented with acute onset right upper quadrant pain. He operated on based on a presumptive diagnosis of acute cholecystitis according to clinical and ultrasonographic findings. Histop...

This study was undertaken to evaluate the overtreatment rate of women with abnormal cervical cytology undergoing colposcopy followed by loop electrosurgical excision procedure (LEEP), the so-called "see and treat" approach. Overtreatment was defined as LEEP specimens containing cervical intraepithelial neoplasia (CIN) 1 or less. In this study, medical records of 192 women with abnormal Pap smea...

Treatment of specimens that contain excessive blood can effectively reduce the unsatisfactory rate; however, a considerable number of unsatisfactory specimens remain. We evaluated the effectiveness of reprocessing unsatisfactory specimens that had too few squamous cells and contained microscopic red blood cells (TFSQRBC).Out of the 688 unsatisfactory specimens at microscopic screening, 197 (28....
