Two women (aged 46 and 56 years) developed annular erythema on their sun-exposed skin, including their forearms and faces, after biweekly i.v. administration of paclitaxel for 3-4 months to treat breast cancer. Both cases showed interface changes of basal keratinocytes and high titers of serum anti-SSA/Ro antibody. The diagnoses of paclitaxel-induced cutaneous lupus erythematosus (LE) were made because the skin eruptions cleared rapidly within 3 weeks after the paclitaxel treatment was discontinued. Paclitaxel is proposed to be a causative agent that can provoke cutaneous LE.

Paclitaxel (Taxol) is an intravenously administered antineoplastic agent derived from the yew tree, Taxus brevifolia, whose mechanism of action involves inhibition of mitosis. Some of the mucocutaneous reactions to the drug that have been observed include alopecia, mucositis, hypersensitivity reactions (with erythema and urticaria), nail changes, changes occurring at intravenous sites, and radiation recall dermatitis. Less commonly, acral erythema, erythema multiforme, pustular dermatitis, and scleroderma-like changes have been described. A female patient who was receiving adjuvant weekly paclitaxel for the treatment of intraductal breast carcinoma developed photodistributed erythema multiforme and onycholysis after sun exposure to the affected areas. Including this woman, paclitaxel-associated photosensitve conditions have only been reported in 9 female oncology patients: onycholysis (5), erythema multiforme and onycholysis (2), photo-recall phenomenon (1), and subacute cutaneous lupus erythematosus (1). The patients were either receiving treatment for breast carcinoma (8) or lung cancer (1). The skin lesions developed on sun-exposed areas, usually after the patient had received several weekly doses of paclitaxel, and resolved following discontinuation of the drug. Several of the patients were subsequently able to receive additional cycles of paclitaxel without recurrence of their drug-associated photosensitive conditions by concurrently using photoprotection to prevent additional sun exposure to the previously affected sites during treatment.
