Gemcitabine-induced radiation recall phenomenon in a post-operative and post-radiotherapy case of peri-ampullary carcinoma during adjuvant chemotherapy.

Radiation recall phenomenon is an inflammatory process occurring at sites of previous radiation subsequent to administration of pharmacologic agents. The most common chemotherapeutic agents implicated with radiation recall phenomenon are anthracyclines and taxanes. Skin is the most common site for radiation recall. About 63% of the radiation recall events are reported to manifest as dermatitis. This finding differs from radiation recall due to Gemcitabine, in which approximately 70% cases manifested as inflammation of internal organs or tissues and 30% manifested as dermatitis. Here, we report a case of post-operative peri-ampullary carcinoma who developed radiation recall dermatitis during adjuvant chemotherapy with inj. Gemcitabine and inj. Carboplatin after concurrent chemoradiation with capecitabine.
