Abstract
Paget's disease of the breast is regarded as a special type of breast carcinoma that originates in the ducts of the nipple and spreads to the nipple epidermis through the ducts.the lower lip in 1978. The tumor gradually increased in size thereafter and measured 2cm in diameter in April 1982. Clinical examination disclosed a freely movable, domeshaped, elastic soft, yellowish lesion, measuring 2×1.5×1cm in the labial mucosa of right side of the lower lip. The clinical diagnosis was benign tumor and the tumor was enucleated under local anesthesia on April 14, 1982. From the histopathological examination, the diagnosis of simple lipoma was made.
Forty-nine months have passed after the surgery, and there have been no signs of recurrences.
Cases 2: A 65-year-old man. In April 1984, he was found to have a tumor on the right side of the lower lip after he bit his lower lip. Thereafter the tumor had been repeatedly increasing and decreasing in size, but did not decrease following an increase in size in March, 1985. Therefore he visited our hospital on April 12, 1985. Oral examination revealed that the tumor was a well-circumscribed, elastic soft mass measuring 7×7×4mm and part of the surface was whitish area considering hyper-kelatinization. The clinical diagnosis of mucocele on the lower lip was made and the lesion was excised under local anesthesia. Postoperative histopathological examination revealed that the lesion was not mucocele but was simple lipoma.
No signs of recurrences have been encountered during eighteen-month follow-up after the surgery.
In the clinicopathological view, it is important to distinguish between Paget's carcinoma that has no palpable mass and Pagetoid carcinoma that has a palpable mass in the breast. From Jan. 1981 to Dec. 1985, we experienced five cases of Paget's disease. Of these five cases, there were three cases of Paget's carcinoma and two cases of Pagetoid carcinoma.
In this paper, we introduce these cases and report on their clinicopathological picture. We also refer to our surgical treatment of Paget's disease.
