Helena Helena is gynecologist, my colleague. Her field of practice is ovarian tumors. Yesterday, before the hospital daily meeting we had very animated conversation about origins of mucinous tumors of ovaries. I was very impressed with her, when she told that mucinous ovarian tumors are usually secondary (i.e. metastatic). There are not a lot of people who know it! Even me, I was very surprised when I found out this issue in books! So, I agreed with her and added that most common origin of them is appendiceal cancer and that these tumors are not very simple in immunohistochemical diagnostics. Then she told me about her patient with mucinous cancer of lung with metastases to ovaries and asked me to examine a tumor (I am pathologist) from another patient with signet-ring tumors to exclude secondary involvement of ovaries. I said her yes and told about my diagnostic troubles with one patient who was operated last week. Today I finished this case. I think Helena will wonder a lot when read my report. I like communicate with the people like Helena. She understand our (pathologists’) work, our limits and troubles. She is also very interested in oncology, in recent studies in this field and always tries to applicate them to her clinical practice.
