Psoriasis aggravation due to lapatinib.

Our patient was a 35-year-old woman, who had undergone right radically modified mastectomy and axillary-lymph-nodes dissection in June 2004. The stage of the patient was T2N0M0. She was treated with six cycles of FAC (5-fluorouracil, doxorubicin, cyclofosfamid), tamoxifen after chemotherapy. In June 2008, right axillary lymphadenopathy progressed and was treated with docetaxel and capecitabine after a hand-foot reaction was observed in the patient as an adverse reaction to capacitabine; the treatment was continued with only trastuzmab between February 2009 and April 2010. The addition of vinoralbine was needed due to the newly developed right paratracheal lymphadenopthy in April 2010. After six cycles of chemotherapy we achieved stable disease; she received only trastuzumab; later on, in control thorax CT, multiple metastatic models were observed in April 2011 and thus lapatinip plus capecitabine treatment was started. After one cycle of chemotherapy her psoriatic lesions were aggravated and we had to stop the treatment.
