AIMS The immunohistochemical expression of cytokeratin 19 (CK 19) and galectin-3 was evaluated in 69 thyroid lesions to assess their potential as markers in the diagnosis and classification of thyroid malignancy. The following were studied: 26 cases of papillary carcinoma, 12 of follicular carcinoma, 20 follicular adenomas, two medullary carcinomas, one(More)
The role of human papillomavirus (HPV) in the aetiology of in situ and invasive carcinoma of the genital tract is well established. In the rare disorder epidermodysplasia verruciformis (EV), in which patients develop extensive warts of unusual types and multiple cutaneous squamous cancers on light-exposed skin, current evidence suggests a probable role for(More)
The Scottish Melanoma Group (SMG) was established in 1979 to assess mortality from and incidence, features, pathological data, and management of cutaneous malignant melanoma in Scotland. Incidence during the first five years and five-year survival have already been reported. We now have data about incidence and mortality over eleven years in relation to(More)
202 renal allograft recipients in south-east Scotland, who had received transplants between 1965 and 1986, were monitored over 3 years (1984-87) for the presence of warts, keratoses, and skin cancers. 77% of 69 patients with graft survival of more than 5 years had viral warts, 38% had keratoses, and 12% had skin cancers, whereas of the 133 with graft(More)
From the Scottish Melanoma Group database for south-east Scotland we evaluated 5-year follow-up in patients with cutaneous malignant melanoma excised between 1979 and 1994 and devised an 'evidence-based' review protocol. Of the 1568 with stage I melanoma, 293 (19%) developed a recurrence, 32 had a second primary melanoma and 97 had an in-situ melanoma. The(More)
We report the pathology of benign and malignant skin lesions from 13 renal allograft recipients. The 59 lesions included 18 squamous carcinomas, 16 verrucous keratoses, 19 warts with varying dysplasia, three plaque lesions resembling those found in epidermodysplasia verruciformis, two non-specific keratoses and one basal cell carcinoma. We delineate(More)
AIMS Clinical management of premalignant and malignant lesions of the larynx is dependent on histopathological evaluation. The Scottish Pathology Consistency Group assessed interobserver variation in the evaluation of laryngeal dysplasia. METHODS AND RESULTS One hundred laryngeal biopsies ranging from normal to invasive carcinoma were assessed. The(More)
Sections from 100 cervical biopsy specimens were studied by 12 consultant histopathologists to determine the robustness of the existing pathology terminology and classification. Analysis by kappa statistics showed good agreement in the diagnosis of CIN 3 and squamous carcinoma but an inability to distinguish accurately between the lesser grades of CIN. It(More)
Metastatic cutaneous Crohn's disease, in which noncaseating granulomatous infiltration of the skin occurs at sites separated from the gastrointestinal tract by normal tissue, is the least common dermatological manifestation of Crohn's disease. We report the case of an 18-year-old man who developed very widespread metastatic cutaneous Crohn's disease 2 years(More)
