Meet the Site’s Host

After working for many years as a clinical pathologist, anatomical pathologist, and pathologists’ assistant, I found my most productive niche as a grossing technologist at the Department of Pathology Loyola University Chicago Medical Center. Here I had an opportunity to summarize my pathology experience, formulate some principles of grossing technology, and propose some “inventions”, namely gadgets, which might be useful in practice.  Actually, most of my “revelations” may already existed, but either there was no information published about them  or they had been forgotten. There is a hidden hope that perhaps  manufacturers will pick up some of them for production.

A fledgling sub-specialty emerges in the surgical pathology laboratory when grossing is assigned to laboratory workers, most often histotechnologists, who do not have systematic pathology education as well as the skills to perform this initial stage of processing, crucial to a pathologist’s diagnosis. Right or wrong, this is a fact of life. In my publications and workshops (Publications in the USA, see below), I have relentlessly promoted grossing technology as a sub-specialty that extends beyond specimen sampling techniques, but includes many aspects of the initial phase specimen processing before histotechnology begins per se. Details of  methodology are key.

The website opens opportunities to express my own views without sensing a reviewer’s disapproval eye . My web home is my castle as the old British might have said if they had known the Internet.
