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.Design: Patients were accrued in the frame of doserange-finding studies that examine the toxic effects and antitumor activity of Doxil therapy in metastatic breast and prostate cancers. All patients receiving Doxil were instructed to report any skin eruption or discomfort. Skin examination was performed on a regular basis at every cycle of Doxil therapy and after specific complaints.Setting: Outpatient day care unit of the oncology institute of a secondary-referral medical center.Patients: Sixty patients (45 women and 15 men). Main Outcome Measures:A basic severity scale of I through IV was adopted for toxic effects to the skin, based on National Cancer Institute common toxicity criteria. Results:The following 4 patterns of skin eruptions were encountered: hand-foot syndrome (n=24), diffuse follicular rash (n=6), intertrigolike eruption (n=5), and new formation of melanotic macules (n=3). Another major toxic effect of Doxil was stomatitis, which was found to be the dose-limiting factor for the maximal single dose. Alopecia and extravasation injuries did not occur. Conclusions: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-liposomeencapsulated form.

The purpose of this communication is to report the evolution of a solar (senile) lentigo into a solitary lichen planus-like keratosis (SLPLK). This case is unique because this evolution was documented by biopsies taken from the same lesion nearly 5 years apart. The pathogenesis of SLPLK is discussed.
