Please write two letters from a dermatologist inviting a patient to book in for a routine skin check. One should be in a formal register, and the other in a very casual style.

Dear [Name],

Our records show that you have requested that we notify you regarding the time elapsed since your last visit for a skin examination.

If you would like to make an appointment, please phone [number] between 8.00 am and 5.00 pm Monday to Thursday. Our office is closed on Fridays. If you have Medical Insurance, please be aware that most policies exclude screening. They usually cover a skin check where you or your GP have concerns about a lesion.

You are welcome to request an appointment by emailing [email address] as well. If you no longer require skin recalls, please advise.

Kind regards,
[Name]

Hi [Name],

Just dropping a quick line to remind you that it's been a little bit since your last skin check. If that sounds like something you're interested in, please let us know - feel free to email me back at this address. You can also give us a ring on [number] from 8 am to 5 pm Monday through Thursday. We're lucky enough to be closed on Fridays, so if you try to get us, then you won't have any luck! 

Oh, while I'm thinking about it, if you have health insurance, it's likely not to cover this routine skin check. Normally insurance only covers it when there's a particular lesion that you or your doctor are concerned about.

Anyway, like I say, please feel free to email or call us, and I'll try and set you right.

Hope to hear from you soon,

[Name]
