An Unusual Case of Stevens-Johnson/Toxic Epidermal Necrolysis Overlap Syndrome in HER2 (Human Epidermal Growth Factor Receptor 2)-Positive Breast Cancer Patient Treated With Docetaxel.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare but life-threatening drug-induced hypersensitivity reactions existing as a disease continuum based on the area of skin detachment. Following three cycles of treatment with docetaxel, a 60-year-old female with early-stage human epidermal growth factor receptor 2 (HER2)-positive breast cancer presented to the hospital with a flu-like illness and black crusting of the bilateral orbits, navel, and perianal region. Nikolsky sign was positive, and the patient was subsequently transferred to a specialized burn center for treatment of SJS/TEN overlap syndrome. There are a small number of cases documenting SJS/TEN following docetaxel administration in cancer patients.
