SummaryBackground The incidence of skin cancer, both melanoma and nonmelanoma skin cancer (NMSC), is rising throughout the world. The evaluation of trends in skin cancer will allow better planning of the future development of skin cancer services. Objectives Using data collected from the Northern Ireland Cancer Registry (NICR), the incidence of the three major cutaneous cancers, basal cell carcinoma (BCC), squamous cell carcinoma (SCC) and malignant melanoma (MM), was determined and the workload associated with their management assessed. Methods The records of patients with a first diagnosis of BCC, SCC or MM occurring between 1993 and 2002 were retrieved from the NICR database. The annual age-and sex-adjusted incidence rates of all three skin cancers were computed per 100 000 person-years by direct standardization according to the European Standard Population. Trends in incidence were estimated by calculating the estimated annual percentage change using Microsoft Excel. For patients registered with the NICR as having BCC, SCC or MM, the number of pathological reports where malignant samples had been examined was counted and then summed to provide the number of specimens examined each year between 1993 and 2004. Results For all three cancers the age-specific rates for both males and females increased with age, except for MM in men aged 75 years and over, where the rates were seen to decrease. Over the 12-year period there was a 62% increase in the overall number of skin cancer samples processed by local pathology laboratories and a 20% increase in the number of patients. These data highlight the fact that many patients will have more than one skin cancer, which reinforces the benefit in collecting data for both patient and sample numbers in order to obtain a true reflection of the workload. The data have also shown that more affluent men and women have higher rates of BCC and MM than their less affluent counterparts. Conclusions In view of the data presented it is clear that management of NMSC and MM will impose significant demands on services in the years ahead. This will impact on the entire multidisciplinary team. Future planning, in terms of manpower and resources, will prove essential if we are to remain in a position to manage our patients with these malignant tumours appropriately.

The Inhibitor of Apoptosis proteins (IAPs) are a family of proteins that are mainly known for their anti-apoptotic activity and ability to directly bind and inhibit caspases. Recent research has however revealed that they have extensive roles in governing numerous other cellular processes.IAPs are known to modulate ubiquitin (Ub)-dependent signaling pathways through their E3 ligase activity and influence activation of nuclear factor B (NFB). In this review, we discuss the involvement of IAPs in individual hallmarks of cancer and the current status of therapies targeting these critical proteins.

Background: Vesiculobullous diseases have been the focus of intensive investigation in recent years. However, these disorders are still associated with substantial morbidity, considerable mortality and impaired quality of life. Accurate diagnosis of vesiculobullous lesions of skin entails evaluation of clinical, histopathologic and immunofluorescence findings.Methods: Hospital based prospective study for a period of 24 months from August 2014 to July 2016 in the Department of Pathology at Andhra Medical College, Visakhapatnam, India. Total of 50 patients aged 3-70 years with vesiculobullous lesions of both sexes attending the Department of Dermatology were selected and analysed clinically, histopathological examination and direct immunofluorescence (DIF).Results: In the present study, majority of patients presented between 51-60 yrs of age (32%) with male to female ratio of 1.08:1 and mean age of 46.02 years. Pemphigus vulgaris constituted the most common vesiculobullous disorder (32%) followed by bullous pemphigoid and pemphigus foliaceous, 18% each. Bullae were located intra epidermally in 68% and sub epidermally in 32% of the patients. DIF was positive in 80% of the cases. Overall clinicopathological correlation was established in 74%. Overall histopathological and direct immunofluorescence correlation was established in 78%. Out of 50 cases, 35 cases (70%) correlated clinically and histo-pathologically with direct immunofluorescence.Conclusions: In the present study, on histopathological examination alone pemphigus foliaceus and pemphigus vulgaris could be differentiated. Direct immunofluorescence was useful in differentiating epidermolysis bullosa acquisita from bullous pemphigoid which have similar histopathological picture. This study proves that direct immunofluorescence is confirmatory as well as diagnostic for vesiculobullous disorders.

BACKGROUND Thyroid nodules are common in clinical practice, occurring globally with wide variation in incidence and histopathological pattern related to age, sex, dietary and environmental factors. This study was undertaken to describe the spectrum, frequency, age, sex distribution and various histopathological patterns of thyroid lesions. MATERIALS AND METHODS The present study is a hospital based prospective observational study conduted for a period of one year from January 2017 to December 2017, and was conducted in the Department of Pathology, Andhra Medical College, Visakhapatnam. Tissue samples for H&E sections were fixed in 10% formalin and subjected to routine paraffin embedded processing and stained with Haematoxylin and Eosin. Various histopathological patterns were observed and compared.
