title: [A case of squamous cell carcinoma of the hard palate in a patient with basal cell nevus syndrome].
abstract: Basal cell nevus syndrome is an autosomal dominant disorder characterized by the developmental malformations and its carcinogenic nature. This syndrome shows various symptoms of multiple cutaneous basal cell carcinoma, ketatocystic odontogenic tumors, and inborn abnormalities in the bone and skin. Although basal cell nevus syndrome itself is a rare disorder, we experienced a very rare case in which squamous cell carcinoma of the oral cavity developed, and not cutaneous basal cell carcinoma. Only 4 similar cases have been reported in the English literature. The patient was a 33-year-old woman. She was diagnosed as having squamous cell carcinoma of the hard palate, and basal cell nevus syndrome in our hospital. The patient underwent surgery for squamous cell carcinoma of the hard palate, with postoperative chemoradiothetrapy. Since patients with this syndrome tend to form basal cell carcinoma when exposed to X-ray radiation, we perform radiotherapy with care.
