Abstract
Merkel cell carcinoma (MCC) is a rare cutaneous neoplasm of presumed neuroendocrine origin, with aggressive behavior and poor prognosis, that tends to have an increased incidence among elderly Caucasians and immunosuppressed individuals. MCC is either associated with a clonal integration of the Merkel cell polyoma virus into the host genome or with genomic alterations caused by chronic UV exposure. Tumors of either carcinogenesis show epithelial, neuroendocrine, and B-lymphoid lineage markers. HIV-infected African albinos have a higher risk of developing skin cancers, including MCC, in comparison with the general population. We report a case of MCC of the head in a young albino woman with a HIV/HTLV-1 coinfection. The patient also suffered from multiple squamous cell carcinomas of the scalp, face, lip, and ears, suggesting an UV carcinogenesis of MCC. The purpose of this case report is to emphasize the relationship between immunosuppression (HIV/HTLV-1 coinfection, chronic sun exposure, ocular-cutaneous albinism, pregnancy) and MCC. It highlights the importance of early diagnosis, dermatological screening with a risk-stratified surveillance, particularly in immunosuppressed albino patients in sub-Saharan Africa, and multidisciplinary management of this biologically unique cutaneous cancer.

Abstract
Cutaneous malignancies are the most common malignancies in Whites; traditionally considered rare among Blacks, their occurrence in sub-Saharan Africa is yet to be fully characterized.Data on specimens submitted between 1992 and April 2008 on all histologically proven primary cutaneous malignancies were collected from the Pathology Department, including patient age, sex, anatomic site of malignancy, and histologic diagnosis. There were 1900 patients with primary cutaneous malignancies, aged between 8 months and 110 years, with a mean age of 49 years. There were 14 different types of malignancies found, with squamous cell carcinoma representing 45% of the total. A number of the rarer types have not been reported previously, from this region.Cutaneous malignancies in Africa present a number of management challenges including the following: difficulties in early diagnosis in the dark skin, late presentation, access to treatment, and the ability to pay for the appropriate treatment. The current human immunodeficiency virus/acquired immune deficiency syndrome scourge on the continent may lead a significant increase in cutaneous malignancies, posing even bigger challenges.

Abstract
Exfoliative and aspiration cytologies play a major role in the management of patients with human immunodeficiency virus infection. Common cytology samples include cervicovaginal and anal Papanicolaou tests, fine needle aspirations, respiratory specimens, body fluids, Tzanck preparations, and touch preparations from brain specimens. While the cytopathologists need to be aware of specific infections and neoplasms likely to be encountered in this setting, they should be aware of the current shift in the pattern of human immunodeficiency virus-related diseases, as human immunodeficiency virus patients are living longer with highly active antiretroviral therapy and suffering fewer opportunistic infections with better antimicrobial prophylaxis. There is a rise in nonhuman immunodeficiency virus-defining cancers (e.g., anal cancer, Hodgkin's lymphoma) and entities (e.g., gynecomastia) from drug-related side effects. Given that fine needle aspiration is a valuable, noninvasive, and cost-effective tool, it is frequently employed in the evaluation and diagnosis of human immunodeficiency virus-related diseases. Anal Papanicolaou tests are also increasing as a result of enhanced screening of human immunodeficiency virus-positive patients for cancer. This paper covers the broad spectrum of disease entities likely to be encountered with human immunodeficiency virus-related cytopathology.

Abstract
Identification of a causative pathogen is essential for the choice of treatment for most infectious diseases. Many FDA approved molecular assays; usually more sensitive and specific compared to traditional tests, have been developed in the last decade. A new trend of high throughput and multiplexing assays are emerging thanks to technological developments for the human genome sequencing project. The applications of microarray and ultra high throughput sequencing technologies for diagnostic microbiology are reviewed. The race for the $1000 genome technology by 2014 will have a profound impact in diagnosis and treatment of infectious diseases in the near future.

Abstract
Merkel cell carcinoma (MCC) is a skin cancer of neuroendocrine origin that occurs most often in sun-exposed areas. In the general population, it is a disease of older adults, with only 5% of cases occurring below the age of 50 years. Immunosuppression is the significant risk factor for the development of MCC and recently it was suggested that individuals with HIV have a relative risk of 13.4 to developed MCC in comparison with the general population. We report a case of MCC in an HIV-infected patient and we review nine patients with HIV with MCC. Our patient was a 54-year-old man who came to our attention without a known HIV diagnosis. He was apparently in good health and had no risk factor for HIV, but by the atypical site of the lesion and by the relative young age of the patient we suspected a case of immunosuppression and for this reason we did HIV test that had a positive result. The patient was treated with surgery and chemotherapy but died as a result of liver metastases 25 months after his tumor was diagnosed.

Abstract
Merkel cell carcinoma (MCC) is a rare and extremely aggressive skin cancer that arises from primary neural cells. It presents most commonly in the elderly and immunocompromised patients. Pathologically, MCC should be distinguished from extrapulmonary small cell lung cancer or metastatic small cell lung cancer or a small cell variant of melanoma. The prognosis is based largely on the stage of disease at the time of presentation. Therapeutic options for MCC include wide resection with or without adjuvant radiotherapy or chemotherapy. Novel therapies based on the understanding of the molecular aspects of MCC are currently being explored.

Abstract
Merkel cell carcinoma (MCC) is a rare, aggressive cutaneous cancer that predominately affects elderly Caucasians with fair skin and has a propensity for local recurrence and regional lymph node metastases. A variety of terms have been used to describe this tumor, including trabecular cell carcinoma, neuroendocrine or primary small cell carcinoma of the skin, and anaplastic cancer of the skin. Although the skin lesion is most commonly found on sun-exposed areas of the head and neck or extremities, it can occur on the trunk, genitalia, and perianal region. The median age is 69 years, but it may occur earlier and more frequently in immunosuppressed patients. Patients with MCC frequently present with a nonspecific erythematous or violaceous firm nodule or small plaque that may be surrounded by small satellite tumors. MCC usually arises in the dermis and extends into the subcutis. It may be difficult to accurately diagnose MCC by light microscopy alone and ancillary techniques, including electron microscopy and immunohistochemistry, may be necessary to make a definitive diagnosis. Management of MCC is dependent on stage of the disease and is hampered by its rarity and lack of randomized trials. Nonetheless, for localized disease most guidelines include wide local excision of the primary tumor either alone or with radiation therapy. Sentinel lymph node biopsy can be helpful in staging and prognosis, but its benefit in survival remains to be seen. Systemic chemotherapy, akin to regimens for small cell carcinoma of the lung, may be considered as an adjuvant following surgery or to treat locoregional or distant disease. The prognosis of MCC is variable. Some patients with localized disease have an indolent course and are well controlled with local excision alone. On the other hand, many tumors are aggressive and have a tendency for locoregional recurrence and distant metastases. Such patients have a grim prognosis with a median survival of 9 months. Successful outcomes are most often seen in patients with early diagnosis and complete excision.

Abstract
AIDS produces profound alterations in normal immunity. Impaired cellular immunity permits new tumor formation as evidenced by the solid-organ transplant literature. The weakened cellular immune system of HIV-infected patients resembles in some ways the iatrogenic immunosuppression in solid-organ transplant recipients. This article summarizes what is known about skin cancer in the solid-organ transplant population and compares the immunodysregulation of HIV infection with the iatrogenic immunosuppression following solid-organ transplantation.

Abstract
PURPOSE OF REVIEW The incidence and spectrum of non-AIDS-defining cancers has continued to grow. As HIV-infected individuals live longer due to highly active antiretroviral therapy, their risk of dying from one of these cancers is increased. The recent literature pertaining to non-AIDS-defining cancers is reviewed. RECENT FINDINGS Recent epidemiological studies have identified higher rates of carcinoma of the anus, lung, breast, skin, conjunctiva, liver and prostate; hematopoietic malignancies such as Hodgkin's lymphoma, plasma-cell neoplasia and leukemia; and other neoplasms like melanoma and leiomyosarcoma in HIV-positive patients. The role of HIV-induced immunosuppression in the development of these non-AIDS-defining cancers appears less important than lifestyle habits like smoking and sun exposure, as well as coinfection with human papilloma, hepatitis B, hepatitis C and Epstein-Barr viruses. SUMMARY It is unclear whether the growing number of reports on non-AIDS-defining cancers reflects a true increased incidence or merely the product of increased surveillance, detection and reporting. Highly active antiretroviral therapy not only promotes longevity in the HIV-positive population, but may increase their risk of developing cancer like Hodgkin's lymphoma. Assertive prevention strategies are needed to adequately deal with non-AIDS-defining cancers in an aging and growing HIV-positive population.
