Host-vs.-altered-host eruptions in patients on liposomal doxorubicin.

BACKGROUND

Anthracycline antitumor antibiotics are the most commonly used chemotherapeutic agents. One of these is doxorubicin. Liposomal doxorubicin was developed as a drug delivery system in order to deliver the active drug intracellularly while decreasing the systemic toxicity, particularly hematological and cardiac toxicity.

METHODS

The clinical and histologic findings of the cutaneous eruptions of associated with liposomal doxorubicin are reviewed.

RESULTS

The eruptions occurred in three women with metastatic ovarian carcinoma who were treated with liposomal doxorubicin. These three patients developed erythematous macular/papular to plaque cutaneous lesions, and in one patient a vesicular component. The eruptions involved the trunk and extremities approximately 3-4 weeks after completions of therapy. None of the patients had any documented infections, and none of the patients had symptoms other than pruritus. The eruptions cleared over a period of weeks to months. Histologic features included an interface dermatitis with numerous apoptotic/dyskeratotic cells within the epidermis, with involvement the intra-epidermal sweat ducts and the infundibulum of hair follicles.

CONCLUSION

We believe that these eruptions represented a chemotherapy induced host-vs.-altered host reaction.
