What Is HER2-Positive Breast Cancer?
What to know if your doctor tells you that you have "HER2-positive" breast cancer.
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.

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.

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.
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.
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.
Lentigo Maligna Melanoma
Lentigo maligna melanoma. A large lentigo maligna on the left cheek with the typical variegation in color. The lesion is flat, macular, and represents in situ melanoma. In the center of the irregular lesion there is a pitch-black nodule indicating a switch from the radial to the vertical growth phase and thus invasiveness: the lesion is now called lentigo maligna melanoma.
