[Secondary adenocarcinoma of the ovary and problems in diagnosis]

In a group of 10 secondary ovarian adenocarcinomas primary tumours were verified by biopsy in colorectal region (8 cases), once in gall bladder and once in appendix. The age of patients varied between 36 up to 60 years. The lesion was unilateral in 8 cases, bilateral in two. Six colorectal adenocarcinoma secondaries reminded a bit of endometroid carcinoma. Two colorectal and a gall bladder carcinoma secondaries resembled ovarian mucinous cystadenocarcinoma. Signet ring cells were not present. Appendical mucinous cystadenocarcinoma produced a metastasis that was alike borderline ovarian mucinous cystadenoma. Intracellular mucin reaction was negative or focally positive in former 6 cases, a diffuse positivity was found in 4 cases.
