  • But risk factors don’t tell us everything. Having a risk factor, or even several risk factors, does not mean that you will get the disease. And some people who get the disease may have few or no known risk factors. Even if a person with basal or squamous cell skin cancer has a risk factor, it is often very hard to know how much that risk factor may have contributed to the cancer. The following are known risk factors for basal cell and squamous cell carcinomas. (These factors don't necessarily apply to other forms of non-melanoma skin cancer, such as...

  • These carriers have different shapes and sizes, and their biogenesis, modality of transport, and delivery to the final destination are regulated by a multitude of very complex molecular machineries, which include cytoskeletal elements, signaling complexes, and lipid modifying enzymes to name a few. A concept that has clearly emerged in the last decade is that each membrane pathway does not represent a close system, but is fully integrated with all the other trafficking pathways.

  • Le Trong Trai et al. (2001) argued that with an abundance of heavily degraded land available for rehabilitation, forest management and other land uses, there is considerable potential for cash earning activities in the buffer zone (for example through economic crop plantations). This activity would also reduce the overall pressure on the forest resources in the nature reserve. They also suggested that current arrangements for forest development and management in the bare lands are costly, create social tensions and seem to be unsustainable in the long run.

  • If some forms of independent production have worked closely in unison with Hollywood, others have operated in areas in which Hollywood has chosen not to tread, sometimes teaching valuable lessons to the dominant institution. Necessity has often driven independent operators to be the pioneers of American cinema, exploring new avenues in their search for territories not already colonized by the major studios. The early independents took cinema to parts of rural America, including the gold camps of Alaska, that were not served by the big companies.

  • Harrison's Internal Medicine Chapter 83. Cancer of the Skin Melanoma Pigmented lesions are among the most common findings on skin examination.

Examples of malignant and benign pigmented lesions are shown in Fig. 83-1. Figure 83-1 Atypical and malignant pigmented lesions. The most common melanoma is superficial spreading melanoma (not pictured). A.

  • Prognostic Factors The most important prognostic factor is the stage at the time of presentation. Fortunately, most melanomas are diagnosed in clinical stages I and II. The revised American Joint Committee on Cancer (AJCC) staging system for melanoma is based on microscopic primary tumor depth (Breslow's thickness), presence of ulceration, evidence of nodal involvement, and presence of metastatic disease to internal sites (Table 83-3). Certain anatomic sites may affect the prognosis.

  • Management The entire cutaneous surface, including the scalp and mucous membranes, should be examined in each patient. Bright room illumination is important, and a 7x to 10x hand lens is helpful for evaluating variation in pigment pattern. A history of relevant risk factors should be elicited. Any suspicious lesions should be biopsied, evaluated by a specialist, or recorded by chart and/or photography for follow-up. Examination of the lymph nodes and palpation of the abdominal viscera are part of the staging examination for suspected melanoma.

  • A lifetime risk of melanoma development of 6% has been estimated. The risk is greatest before age 5 and next greatest between ages 5 and 10. Early detection of melanoma is difficult in these lesions because of the deep dermal or subcutaneous origin of primary melanoma and because of the large and varied surface of the nevus. Prophylactic excision early in life can be accomplished by staged removal with coverage by split-thickness skin grafts. Surgery cannot remove all at-risk nevus cells as some may penetrate into the muscles or central nervous system below the nevus. At present there are...

  • Clinical Characteristics There are four types of cutaneous melanoma (Table 83-2). In three of these—superficial spreading melanoma, lentigo maligna melanoma, and acral lentiginous melanoma—the lesion has a period of superficial (so-called radial) growth during which it increases in size but does not penetrate deeply. It is during this period that the melanoma is most capable of being cured by surgical excision. The fourth type—nodular melanoma—does not have a recognizable radial growth phase and usually presents as a deeply invasive lesion, capable of early metastasis.

  • Biopsy Any pigmented cutaneous lesion that has changed in size or shape or has other features suggestive of malignant melanoma is a candidate for biopsy. The recommended technique is an excisional biopsy, as that facilitates pathologic assessment of the lesion, permits accurate measurement of thickness if the lesion is melanoma, and constitutes treatment if the lesion is benign.
