Atypical moles, often referred to as Atypical Nevus or Nevi, typically appear on the upper back, torso, lower legs, head and neck.
Knowing that 20% to 27% of cutaneous SCCs arise in an AK or within 8 mm of such and that an AK is genetically identical to a cutaneous SCC, we can further postulate that the lesions underlying the diagnosis of "atypical squamous proliferation" in our study required clinical treatment of some sort 59% of the time.

The Bethesda System 2001 classification scheme for cervical cytologic specimens divides atypical squamous cells (ASC) into 2 subcategories: ASC of undetermined significance (ASCUS) and ASC, cannot exclude a high-grade squamous intraepithelial lesion (HSIL) (ASC-H). A hysterectomy stops symptoms and eliminates cancer risk.
Basal cell carcinoma is a common tumor; therefore, collision of lesions with other epidermal and dermal neoplasms produces unusual clinical appearance and includes basal cell carcinoma and seborrheic keratosis, intradermal melanocytic nevus, verruca vulgaris, syringoma, and melanoma.
