Multiple primary visceral malignancy--a review with report of two cases.

ABSTRACT

Multiple primary cancers are being reported with increasing frequency in recent years, the frequency varying from 0.3 to 4.3% in different studies. A combination of primary cancer of larynx and lung is the most common followed by malignant neoplasm involving lip-larynx, skin-larynx, skin-lung, breast-ovary and breast-endometrium. Two interesting cases of rare combinations of primary cancers are being presented. In the first case primary adenocarcinoma of the gall bladder was associated with appendiceal adenocarcinoma. In the second case primary malignant papillary serous cystadenocarcinoma of right ovary and squamous cell carcinoma of cervix uteri were found.
