Giant basal cell carcinoma associated with systemic amyloidosis.
A large basal cell carcinoma, 39 x 26 cm in size, is presented as second in size only to the largest basal cell carcinoma documented (40 x 30 cm), reported by Beck and co-workers (1). A 61-year-old Japanese male visited our clinic with a huge ulcerating tumor on the back. He had hidden the tumor for the previous 30 years. The tumor was histologically confirmed as basal cell carcinoma. The condition was associated with anemia, hypoproteinemia, and dyspnea, and with systemic amyloidosis in the skin, in the lymph nodes, and in the intestinal canal. On admission, the tumor had metastasized to the regional lymph nodes, and, about two years after the first operation, there were metastases to bone and lung, leading to death due to respiratory failure.
