[font=arial, helvetica, sans-serif]Pictures show a lesion that can be a keratoacanthoma or a squamous-cell carcinoma. Differentiate between both is a difficult task that hardly could be achieved on microscopic examination alone. In this particular case, history is more effective than images.[/font]
[font=arial, helvetica, sans-serif]I favor keratoacanthoma after a history of a rapidly growing nodule with a central cavity. However, some microscopic features of keratoacanthoma can be found: exo-endophytic silhouette, absence of ulceration, neoplastic keratinocytes with abundant pale-staining cytoplasm.[/font]

Ä°nvasive SCC (well differentiated), I couldn't observe symmetry, central plugging as well as neutrophilic microabscesses for KA.

It is nice to be back after having been travelling a lot for the past weeks.
This case is always a difficult diagnostic dilemma. I have never been comfortable with the diagnosis of KA since (A) I regard KA as a variant of SCC and (B) some perfect so-called KA's that I have personally expereinced have metastasized and killed the patient. I would regard this lesion as a KA variant of SCC and have it completely excised. I am well aware that many authorities and experts completely disagree with me but at the end of the day you have to decide how you yourself view KA and act accordingly.

I agree with the diagnsis of well differenciated SCC.
To add:
No lips, no central plugging
No cup-like endo-exophitic shape
