Can you tell us which books you followed in your medical college related to Pathology and Medicine? As far as I know the most popular books for pathology and medicine are Robbins & Cotran and Harrison's respectively where the latter is thicker (since it comes in 3 volumes) and no it is no where near 1ft in thickness (even after keeping all 3 books one over other). Which 1ft thick book are you talking about here? The only thicker book I have seen that lies between Harrison's and Robbins is probably Bailey & Love's which is also not 1ft thick.

Also for your kind information (although you should know it as you are already a doctor), any disease is classed after its causative agent has been found. Delusion cannot be clubbed with any disease that has some organic cause and thus delusional parasitosis is "not a parasitic" disease...not because parasites have not been found...but because it is considered as delusion. It is being treated for Delusions...because it is a delusion. There are no two ways about it.
