OBJECTIVE To review the results of patients who were referred for posthysterectomy of abnormal cytology based on screening indications. MATERIALS AND METHODS We performed a retrospective review of 64 patients who have been referred for posthysterectomy vaginal colposcopy to the gynecologic oncology service. Patients' demographics, clinical features, reason for screening, and final diagnosis w...

AIM To evaluate the usefulness of counting nucleolar organiser region associated proteins (AgNORs) in the management of anal squamous neoplasia. METHOD Using a silver staining technique for NOR associated proteins, 32 routinely processed paraffin wax embedded sections of anal epithelium were assessed. These consisted of normal anal epithelium (n = 9), anal intraepithelial neoplasia (AIN) grad...

purpose: to report a case of isolated corneal squamous cell intraepithelial neoplasia in a patient with unilateral dry eye symptoms. case report: a 48 year old man presented with history of thermal corneal injury in his left eye two years ago, with decreased visual acuity and dry eye symptoms a short time thereafter. he was treated for dry eye with no improvement in symptoms. upon presentation,...

CD44 and beta-catenin are adhesion molecules expressed on a wide variety of cells. Failure of this expression is believed to lead to disruption of cell-cell adhesion and to neoplasia. The aim of this study was to investigate the staining intensity of CD44 and beta-catenin in keratoacanthomas and squamous cell carcinomas of the skin. The proliferation index, PCNA staining, was also evaluated in ...

New data have emerged since publication of the American Society for Colposcopy and Cervical Pathology's 2001 consensus guidelines for management of abnormal cervical cytology and histology. The 2006 guidelines include recommendations for special populations (i.e., adolescents and pregnant women). Human papillomavirus testing is now included for management of atypical glandular cytology, for fol...

Esophageal cancer is the sixth most common cause of cancer death in the world [1]. Over 80% of esophageal cancers occur in developing countries [1], and in these areas, 90% of these cancers are esophageal squamous cell carcinoma (ESCC) [2]. The precursor lesion of ESCC is squamous intraepithelial neoplasia (squamous dysplasia), defined histologically as nuclear atypia (enlargement, pleomorphism...

Bowen's disease, also known as an intraepithelial squamous cell neoplasia, is a carcinoma in situ firstly reported in 1912 by a dermatologist named Bowen from the United States [1]. About 3%~5% of Bowen's disease might develop into invasive squamous cell carcinomas of mocusa and skin [2]. Surgical resection is preferred because of its low recurrence. Here we reported a rare Bowen's disease case...

PURPOSE The purpose of this study was to assess the relative frequency of epithelial lesions of the conjunctiva in Canada. METHODS A retrospective study of 12,102 consecutive cases received during 16 years (1993-2009) at the Henry C. Witelson Ocular Pathology Laboratory in Montreal, Canada, was performed. Demographic data was retrieved from histopathological request forms and specimens were c...

The esophageal squamous cell carcinoma (ESCC) is usually develped from low-grade intraepithelial neoplasia (LGIEN) and high-grade intraepithelial neoplasia (HGIEN) to infiltrative squamous cell carcinoma. Till now, it remains hard to screen for infiltration at earlier stages, especially the differentiation between HGEIN and early infiltrative carcinoma. The purpose of this study is to determine...
