Whats the appointment for?

I went for an urgent refferal with my toe to dermatology on the 17th july. By chance while i was there a lession was found that they said needed removing. I was told they will monitor my toe and come back in 3 months for that. I had the lesion removed on the 2nd august. I was told 6-8 weeks for results.

Today 21st august i had a message on my nhs app saying theyve scheduled me an appointment for 4th september. The appointment says follow up consultation.

Will this be for my toe or my results of my biopsy? 

Any knowledge would be appreciated as neither are within the time they said origionally
