I think it might be Atypical genital or flexural nevi. The associated epidermis is a bit papillomatous. The junctional component quite lintigenous and nested with some architectual atypia. Mild cytological atypia is present also.
Dermal componet looks bland wih maturation, i think. Considering site and age, I guess this is benign

Nevus of inguinal region comprising enlarged, irregularly shaped and unevenly spaced junctional nests on the flanks of the lesion and intradermal small nests and cords, but inconspicuous junctional component, on the center of the lesion. Cytological features of the melanocytes are bland and mitotic figures were not identified.
I’d call this special site nevus and I’d alert for the likely recurrence of the lesion in a few months due to incomplete excision.

Looks benign and agree with above but might want to add naevus spilus (agminate naevus) as there may be more than one focus of naevus here.

The Ki67 is low in the dermal component. I don't see pagetoid spread. Even though there is some architercural disorder, I think it is related mostly to the anatomical localization. My diagnosis would be special site nevus. It is benign, but I would probably advise the clinician that the lesion might persist / recur with a worrisome look.
