    1. Less Common Skin Cancers

      Uncommon types of skin cancer include Kaposi's sarcoma, mainly seen in people with weakened immune systems.

    2. Squamous Cell Carcinoma

      Squamous cell carcinoma. A round nodule with central hyperkeratosis, firm and indolent. This lesion cannot be distinguished clinically from keratoacanthoma; it is easily distinguished from nodular BCC because BCC does not develop hyperkeratosis.

    3. Squamous Cell Carcinoma with Central Hyperkeratosis

      Squamous cell carcinoma. A round nodule with central hyperkeratosis, firm and indolent. This lesion cannot be distinguished clinically from keratoacanthoma; it is easily distinguished from nodular BCC because BCC does not develop hyperkeratosis.

    4. Merkel Cell Carcinoma

      Merkel cell carcinoma. A barely noticeable 6-mm slightly dermal nodule below the hairline that had been present for about 6 weeks. Preauricular lymph node metastasis was also present.

    5. Malignant Melanoma

      Malignant melanoma. Less than 2 percent of all melanomas occur during childhood. Nonetheless, attention must be paid to signs and symptoms suggestive of this potentially fatal disease. Variegations of color are of particular concern. Irregular or notched borders, bleeding, and ulceration are other signs of malignant change. The patient may give a history of itching, and the parents may have noted rapid growth of the lesion. Because the prognosis of a melanoma is most closely related to the thickness of the lesion at the time of treatment, emphasis should be on early diagnosis.

    6. Desmoplastic Melanoma

      Desmoplastic melanoma. A flat nodule with bluish-red and brown portion in an elderly male; lesions often are surrounded by a macular portion resembling lentigo maligna.

    7. Basal Cell Carcinoma

      Basal cell carcinoma, pigmented. A nodule with irregular borders and variegation of melanin hues, easily confused with a malignant melanoma. Features indicating BCC are the areas of translucency and surface telangiectasia.

    8. Basal Cell Carcinoma: Advanced Nodular BCC

      Basal cell carcinoma. This is a farther advanced nodular BCC. A solitary, shiny, nodule with large telangiectatic vessels on the ala nasi, arising on skin with dermatoheliosis.

    9. Squamous Cell Carcinoma on the Calf

      Squamous cell carcinoma in situ: Bowen's disease. A large, sharply demarcated, scaly, erythematous plaque simulating a psoriatic lesion on the calf.

    10. Skin Cancer

      Basal cell carcinoma and squamous cell carcinoma have been linked to chronic sun exposure, typically in fair-skinned people who work outside. Melanoma is associated with infrequent but excessive sunbathing that causes scorching sunburn.
