To assess the risk of developing a basal cell carcinoma (BCC), and/or a squamous cell carcinoma (SCC), and/or Bowen disease (SCC in situ) after a nonmelanoma skin cancer (NMSC) of a specific type. ⋯ Although these studies vary in their study type, location, and biases, their results are consistent. The risk of developing a subsequent skin cancer of a specific type depends on the type of prior NMSC and number of prior skin tumors of that type. Based on these findings, follow-up strategies for patients with BCC and SCC are suggested.

Randomized Controlled Trial Clinical Trial
Skin toxic effects of polyethylene glycol-coated liposomal doxorubicin.
To record the profile of toxic effects of polyethylene glycol-coated liposomal doxorubicin hydrochloride (Doxil) to the skin, and to evaluate whether the long circulation pattern and enhanced accumulation of liposomes in specific skin sites will result in any unique presentations. ⋯ The profile of toxic effects of Doxil to the skin reflects its unique pharmacokinetics and tissue distribution. These skin reactions vary significantly from those associated with doxorubicin in non-liposome-encapsulated form.

In patients with cutaneous melanoma, early age at disease onset is characteristic in familial cases and in individuals with multiple primary melanomas. Both subsets of patients with melanoma are at risk for harboring germline CDKN2A or CDK4 mutations. ⋯ Germline CDKN2A and CDK4 mutations are not common in patients who develop melanoma at an early age. This finding contrasts with other cancer-predisposition syndromes, in which there is an increased incidence of germline mutations among young patients. Selection of patients with melanoma for genetic testing based solely on age at onset may not be warranted at the current time.
