[A case of squamous carcinoma in the buccal region treated with Mohs chemosurgery in a patient with senile dementia of Alzheimer type].

ABSTRACT

An 89-year-old woman was given a diagnosis of senile dementia of Alzheimer type around 2003. In 2006, the patient was examined at a dermatology clinic complaining of tumor in the right buccal region. At the time, possible squamous carcinoma was pointed, but nothing was done for it. In March 2008, home care became difficult due to progression of dementia, and the patient was admitted to our hospital. On admission, a protruding skin tumor (20 x 20 x 2 mm, cauliflower-like surface) was observed in the right buccal region. Surgical ablation was recommended, however, the family strongly requested to let it follow its in natural course. In December 2008, the tumor increased rapidly to 40 x 55 x 25 mm with bleeding and a bad smell, which decreased her QOL markedly. After obtaining consent from the patient and her family, Mohs chemosurgery was performed. As the result, the tumor resolved and the QOL improved. Mohs chemosurgery is considered as a very effective treatments for rapidly advancing progressive skin cancer in patients with severe cognitive impairment.
