I think it is pretty realistic but really depends on individual interest. Back in 2010 or 2011, ABD changed the derm training requirements for path trained dermpath fellows. These days you have to do eight months of half a day derm clinics and work essentially as a derm resident rather than passive observation. Every institution is different, in my fellowship year, I was seeing upward of 20 patients per day, doing procedures, prescribing medications etc. At the end of that year, I felt pretty confident with bread and butter general derm stuff. Keep in mind, most of general derm is repetitive and there are limited number of medications. In a community practice 90% of patients are for routine stuff, AKs, SCC, BCC, DNs, MM, DFs, SKs, VV, skin tags etc. On inflammatory side, prob half of the patients are for acne, than you have eczema, seb derm, rosacea etc. Of course, there will be a small percentage of complex medical derm patients, those would definitely need to be seen by a dermatologist. These will include biologics for psoriasis, immunobullous disease, SLE etc. On the other hand, keep in mind, there is more money in signing out skin biopsies rather than seeing general derm patients. A level 2 clinical encounter, roughly pays 60-100 bucks at most, whereas an 88305 pays $70-$120 depending on type of insurance. An experienced dempath can sign out 150 cases a day and still go home at 3 PM, on the other hand, no one can realistically see more than 45-50 patients a day and can still do a good job.
