“…Thus, the original description of this lesion is credited to Jadassohn, 105 who in 1926 described it as a proliferation of small, clonal‐appearing squamoid cells, forming frequent whorls in an acanthotic epidermis. Montgomery was the first to use the term ‘intraepidermal epithelioma’, and considered it to be a malignant neoplasm 106 . Smith and Coburn 107 identified a subset of IEEs thought to be derived from acrosyringeal metaplasia, which they termed hidroacanthoma simplex 107 …”

Cutaneous squamous cell carcinoma (SCC) includes many subtypes with widely varying clinical behaviors, ranging from indolent to aggressive tumors with significant metastatic potential. However, the tendency for pathologists and clinicians alike is to refer to all squamoid neoplasms as generic SCC. No definitive, comprehensive clinicopathological system dividing cutaneous SCCs into categories based upon their aggressiveness has yet been promulgated. Therefore, we have proposed the following based upon the malignant potential of SCC variants, separating them into categories of low ( 2% metastatic rate), intermediate (3-10%), high (greater than 10%), and indeterminate behavior. Low-risk SCCs include SCC arising in actinic keratosis, HPV-associated SCC, tricholemmal carcinoma, and spindle cell SCC (unassociated with radiation). Intermediate-risk SCCs include adenoid (acantholytic) SCC, intraepidermal epithelioma with invasion, and lymphoepithelioma-like carcinoma of the skin. High-risk subtypes include de novo SCC, SCC arising in association with predisposing factors (radiation, burn scars, and immunosuppression), invasive Bowen's disease, adenosquamous carcinoma, and malignant proliferating pilar tumors. The indeterminate category includes signet ring cell SCC, follicular SCC, papillary SCC, SCC arising in adnexal cysts, squamoid eccrine ductal carcinoma, and clear-cell SCC. Subclassification of SCC into these risk-based categories, along with enumeration of other factors including tumor size, differentiation, depth of invasion, and perineural invasion will provide prognostically relevant information and facilitate the most optimal treatment for patients.Non-melanoma skin cancer is, by far, the most common cancer in humans, basal cell carcinoma (BCC) being the most prevalent type. 1-3 While numerous subtypes of BCC have been elucidated, with the exception of a very few (i.e. sclerosing and micronodular types), the remainder are mere histologic curiosities without any clinical implications. In contrast, the rich diversity of cutaneous squamous cell carcinoma (SCC), which includes subtypes with widely varying clinical behaviors, is clearly underappreciated. 2-11 If one includes actinic keratosis (AK), typically considered a type of

“…1 The eponymic title was derived from cases presented by Borst in 1904 2 and Jadassohn in 1926. 3 Actually, Borst's case was an example of intraepidermal spread of an invasive cancer of the lower lip and represented quite a different lesion from what is commonly included under this title today.…”
