Immunotherapy, in the context of cancers, involves the use of various drugs to stimulate the immune system to target cancer cells. Immunotherapy is being increasingly used for cutaneous malignancies, especially melanoma. Immunity plays an important part in protection against cancer. One of the factors limiting the effectiveness of host immunity is improper recognition of cancer cells. Sometimes, despite recognizing the cancer cells as abnormal, the immune response, for various reasons might not be strong enough to deal effectively with the cancer cells. Immunotherapy basically tries to address the two points mentioned above by improving the capacity of the immune system to recognize and effectively destroy cancer cells. In skin cancers, immunotherapy is best established for melanomas, but is increasingly being used for non-melanoma skin cancers too. This article reviews some of the general concepts about immunotherapy in cancer and discusses in detail, the available options and future possibilities in the applications of immunotherapy in skin cancer.

The prevalence of malignant skin cancers has increased significantly over the past several years. Approximately 1.2 million cases of non-melanoma skin cancer are diagnosed per year. More alarming, up to 80,000 cases of melanoma are diagnosed per year, an incidence that has been steadily increasing, with a lifetime risk of 1 in 50 for the development of melanoma. The disturbing increase in the incidence of both non-melanoma skin cancer and melanoma can largely be attributed to the social attitude toward sun exposure. The clinical assessment and management of skin lesions can be challenging. This review describes the assessment process, including thorough history and examination; the need for possible biopsy; and excision criteria. Specific types of skin cancer are distinguished and include basal cell carcinoma; squamous cell carcinoma; and melanoma; and for each type the incidence; epidemiology; histologic subtypes; diagnosis; and both surgical and non-surgical treatments are provided. Stages I-IV of melanoma are detailed, with prognostic factors described. Surgical treatment for stages I and II include description of the margins of excision and sentinel lymph node biopsy. The surgical treatment of Stage III melanoma further includes therapeutic lymph node dissection and isolated limb perfusion. Adjuvant therapies are also presented and include radiotherapy and chemotherapy. The additional treatment of metastasectomy for Stage IV melanoma is described. For both Stage III and IV melanoma, the study of vaccines to host immune cells is reported. For Stage IV melanoma, the text also describes immunotherapy treatment. Operative procedures specific to superficial and deep groin dissections are outlined. This review contains 9 figures, 3 tables, and 96 references.

Organ transplant recipient (OTR) subjects are at high risk of skin cancer such as squamous cell carcinoma and basal cell carcinoma. Actinic keratosis (AK) is considered the precursor of these non-melanoma skin cancers. Sun protection is mandatory in subjects with AK and this preventive strategy is very important in OTR. Treatment of the field of cancerization is also crucial to reduce the risk of recurrence of skin lesions in AK and non-melanoma skin cancer patients. Activation of cyclooxygenase 1 and 2 enzymes plays an important role in the pathogenesis of skin cancers. Topical application of cyclooxygenase inhibitors such as diclofenac and, more recently, piroxicam has shown to reduce AK lesions in immunocompetent subjects. A medical device containing piroxicam and SPF 50+ sunscreen filters (P+SS) has been demonstrated to be effective in reducing AK lesions and improving the field of cancerization. We report the effect of P+SS, applied for 16 weeks, in a case series of 10 OTR subjects with multiple AK lesions. P+SS treatment was associated with a relevant AK lesion reduction (>75%) in 7 patients (with a complete clearance in 3 subjects) with an improvement in the field of cancerization. This medical device could be considered a promising long-term curative and preventive treatment in OTR patients at high risk of non-melanoma skin cancers.

ABSTRACTAll microorganisms dependent on persistence in a host for survival rely on either hiding from or modulating host responses to infection. The small molecule phosphorylcholine, or choline phosphate (ChoP), is used for both of these purposes by a wide array of bacterial and parasitic microbes. While the mechanisms underlying ChoP acquisition and expression are diverse, a unifying theme is the use of ChoP to reduce the immune response to infection, creating an advantage for ChoP-expressing microorganisms. In this minireview, we discuss several benefits of ChoP expression during infection as well as how the immune system fights back against ChoP-expressing pathogens.

Mohs surgery is considered ideal treatment for many types of skin cancers. Developed by Dr Frederic Edward Mohs (1910-2002), Mohs surgery allows all surgical margins to be viewed microscopically, ensuring no cancer cells go unremoved, yet it failed to achieve immediate acceptance when first introduced in the 1940s. A catalyst to the widespread acceptance of Mohs surgery occurred with the work of dermatologic colleagues who reported excellent results without using the paste. It suggested the real innovation of Mohs surgery lay in its microscopic control and not the paste, the discontinuation of which removed all the problems associated with its use.

One of the most popular types of skin cancer is acral lentiginous melanoma, which usually appears as an irregular, prominent growth on the palms of the hands, feet, or under the nails. In fact, the symptoms of this cancer, which is a prominent colored spot on the skin, slowly begin to appear. In the first stage, malignant cells remain inside the tissue for months or years. The lesion then acts aggressively and appears on the skin as it exits the epidermis. Experts say this type of melanoma can grow rapidly and penetrate deep into the skin. Unlike other skin cancers that occur due to overexposure to the sun, acral melanoma has nothing to do with it. In appearance, these types of cancer spots are more than 6 mm in size and can be brown, blue-gray, black or red. Early in the onset of the disease, the melanoma may have a smooth surface, but over time it becomes thicker and has a dry, uneven surface. Bleeding and sores on the cancerous spot are also possible in some cases. Now that we know that this type of cancer is not caused by the sun's rays, then what is the reason for its occurrence? Experts say our skin has natural pigments. However, melanoma linginosis develops when some malignant pigment cells begin to proliferate in the primary layers of the epidermis. Scientists do not yet know for sure why pigment cells become malignant, but it may be rooted in genetic mutations. When a doctor diagnoses skin cancer in a person, he or she removes the cancerous spots. This process can be more complicated depending on the size of the cancer cells. If the cancer has spread to the lymph nodes, the healing process will take longer. As with other cancers, early detection of skin cancer can speed up the healing process. Therefore, after seeing any spots or colored spots on the palms of your hands, feet or under your nails, see a specialist immediately.

Skin cancers represent the most common human tumors with a worldwide increasing incidence. They can be divided into melanoma and non-melanoma skin cancers (NMSCs). NMSCs include mainly squamous cell (SCC) and basal cell carcinoma (BCC) with the latest representing the 80% of the diagnosed NMSCs. The pathogenesis of NMSCs is clearly multifactorial. A growing body of literature underlies a crucial correlation between skin cancer, chronic inflammation and immunodeficiency. Intensity and duration of immunodeficiency plays an important role. In immunocompromised patients the incidence of more malignant forms or the development of multiple tumors seems to be higher than among immunocompetent patients. With regards to people living with HIV (PLWH), since the advent of combined antiretroviral therapy (cART), the incidence of non-AIDS-defining cancers (NADCs), such as NMSCs, have been increasing and now these neoplasms represent a leading cause of illness in this particular population. PLWH with NMSCs tend to be younger, to have a higher risk of local recurrence and to have an overall poorer outcome. NMSCs show an indolent clinical course if diagnosed and treated in an early stage. BCC rarely metastasizes, while SCC presents a 4% annual incidence of metastasis. Nevertheless, metastatic forms lead to poor patient outcome. NMSCs are often treated with full thickness treatments (surgical excision, Mohs micro-graphic surgery and radiotherapy) or superficial ablative techniques (such as cryotherapy, electrodesiccation and curettage). Advances in genetic landscape understanding of NMSCs have favored the establishment of novel therapeutic strategies. Concerning the therapeutic evaluation of PLWH, it’s mandatory to evaluate the risk of interactions between cART and other treatments, particularly antiblastic chemotherapy, targeted therapy and immunotherapy. Development of further treatment options for NMSCs in PLWH seems needed. We reviewed the literature after searching for clinical trials, case series, clinical cases and available databases in Embase and Pubmed. We review the incidence of NMSCs among PLWH, focusing our attention on any differences in clinicopathological features of BCC and SCC between PLWH and HIV negative persons, as well as on any differences in efficacy and safety of treatments and response to immunomodulators and finally on any differences in rates of metastatic disease and outcomes.

Skin cancer is very common in the UK, and its incidence is rising rapidly. There are two broad classes of primary skin cancer: non-melanoma and melanoma. Non-melanoma skin cancer is the commonest form (100 000 cases diagnosed annually in the UK), accounting for nine out of ten skin cancers and includes basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). Cutaneous melanoma is less common (10 000 cases diagnosed in the UK annually) but confers a significantly worse prognosis and accounts for 75% of skin cancer related deaths. There are also a number of other, rarer, non-melanoma skin cancers (e.g. appendageal carcinomas, Merkel cell carcinoma, sarcomas, vascular malignancies, and cutaneous lymphomas); however, these account for less than 1% of all skin cancers in the UK and so will not be specifically discussed in this chapter. Cutaneous metastases can occur secondary to any internal cancer or, indeed, to skin cancer (e.g. melanoma). In most cases, cutaneous metastasis occurs after the diagnosis of a primary cancer and usually in late stages of the disease but, in some cases, it may be the first presentation, in which case it should prompt a thorough investigation for the primary malignancy.

AbstractBasal cell carcinoma, squamous cell carcinoma, and melanoma represent the three most common skin cancers that occur on the face. The most common surgical treatments for facial skin cancers are Mohs surgery and standard local excision. The effective utilization of either of these techniques is based on tumor and patient risk stratification incorporating known risk factors for occult invasion and local recurrence, combined with patient comorbidities, expectations, and desires. Best available evidence highlights multiple and consistent risk factors for each specific skin cancer type, and dictate local control rates reported in the literature. Recognizing gaps in the literature, we compare and review surgical treatment guidelines and data for standard local excision versus Mohs surgery for cutaneous nonmelanoma and melanoma skin cancer. This article serves as a resource for optimal therapeutic decision making for surgical management of skin cancer on the face.
