Recall dermatitis after systemic treatment with paclitaxel

Area of Science:

• Dermatology
• Oncology
• Pharmacology

Background:

• Recall dermatitis is a known phenomenon at radiation sites after systemic therapy.
• This report details a rare case of recall dermatitis without prior radiation exposure.

Observation:

• A patient receiving paclitaxel for breast cancer developed skin reactions on the arm where the drug was administered.
• The reaction recurred on the previously affected arm when paclitaxel was administered to the contralateral arm.

Findings:

• The observed skin changes, initially misdiagnosed as erysipelas, were diagnosed as recall dermatitis based on clinical presentation and laboratory findings.
• This case contributes to understanding the etiopathogenesis of skin recall phenomena.

Implications:

• Accurate diagnosis of this rare dermatological entity is crucial for appropriate patient management.
• Further discussion on the mechanisms and associated drugs for skin recall reactions is warranted.
