Clear cell BCC is a consideration.

But I have same opinion of Anil, that this may represent a rare variant of Bowen; Warty and clear cell Bowen's disease (WCCBD) or rather clear cell type of Bowen .This type usually occur on the temple, and  has been linked to HPV.

Just to add intraepidermal sebaceous (or sweat glands)  neoplasms are down in the list of DDX.

It could be an intraepidermal component of sebaceous carcinoma.

If the pictures represent the entire lesion, this is a sebaceous in situ carcinoma.

Thank everyone for the insightful discussion. This is an SCCIS with pagetoid spread. DDX includes MIS, sebaceous carcinoma in situ and EMPD.
