Evolution of a 4 mm nodular melanoma. Nodular melanoma (NM) is the most aggressive form of melanoma. [1] It tends to grow more rapidly in thickness (vertically penetrate the skin) than in diameter compared to other melanoma subtypes. [2] Instead of arising from a pre-existing mole, it may appear in a spot where a lesion did not previously exist.
Diagnostic mammograms may also performed on patients with personal or family histories of breast cancer. Patients with breast implants and other stable benign surgical histories generally do not require diagnostic mammograms. Until some years ago, mammography was typically performed with screen-film cassettes.
A deep penetrating nevus is a type of benign melanocytic skin tumor characterized, as its name suggests, by penetration into the deep dermis and/or subcutis. Smudged chromatic is a typical finding. In some cases mitotic figures or atypical melanocytic cytology are seen, potentially mimicking a malignant melanoma.
However, a melanocytic nevus is benign, and melanoma is malignant. Most melanocytic nevi never evolve into a cancer, with the lifetime risk for an individual nevus being 1 in 3000 for men and 1 in 11 000 for women. [5] Moreover, dermatologists have a standardized system for determining whether a skin lesion is suspicious for malignant melanoma.
The evaluation of a skin nodule includes a description of its appearance, its location, how it feels to touch and any associated symptoms which may give clues to an underlying medical condition. [4] Often discovered unintentionally on a chest x-ray, a single nodule in the lung requires assessment to exclude cancer. [9]

This is partly due to dense tissues obscuring the cancer and the fact that the appearance of cancer on mammograms has a large overlap with the appearance of normal tissues. Additionally, mammogram should not be done with any increased frequency in people undergoing breast surgery, including breast enlargement, mastopexy, and breast reduction. [14]
