We report the case of a 42-year-old woman who was diagnosed with breast cancer that recurred 3 years later, with supraclavicular lymphadenopathy and dermal involvement. The main drug used in the therapy was trastuzumab; however, the association of this drug with docetaxel was not able to decrease or cease the effect of the inflammatory BCA component with erythema and thickening of the skin as well as the supraclavicular lymphadenopathy previously diagnosed. Thus, a combined therapy was required. The patient was started on 6 cycles (1 per month) of trastuzumab subcutaneous 600 mg, pertuzumab intravenous 840 mg (as an attack dose, later on 420 mg), and xeloda oral 1000 mg. As a result, the patient showed a significant improvement in erythema and thickening of the skin in the neck and the right part of her trunk, besides decrease in supraclavicular lymphadenopathy. After 6 cycles, her skin was almost restored. Intravenous trastuzumab can be an effective single agent; however, its association with other chemotherapies-such as pertuzumab-can present a synergic effect, which can increase the survival expectations of metastatic HER2+ patients. Additionally, as reported in the literature, the use of xeloda plays a key role in restoring the skin health of patients with breast cancer presenting with skin metastasis. Our findings suggest that trastuzumab, pertuzumab, and xeloda combined therapy, following the schedule and posology handled in this study, can be a good treatment for recurrent HER2+ breast cancer with signs of supraclavicular lymphadenopathy and severe inflammatory BCA component with erythema and thickening of the skin.
