benign lichenoid keratosis

has been specific to cancerous lichenoid keratosis along with keratoacanthoma, although not with halo nevus.

The actual arteries and exhibited endothelial mobile swelling using luminal narrowing along with interruption inside the skin coming from all lesions.

The actual CD1a positive tissue had been increased with range with lesional skin color except with keratoacanthoma lesions the place that the solidity associated with CD1a positive tissue has been increased inside epithelial top, however reduced inside the epithelial portion of this keratoacanthoma suitable. On the other hand, this CD8 positive tissue had been scarce inside skin below this epithelial top of the keratoacanthoma, however increased inside skin of the neoplastic epithelium.
