With clinical correlation, the most likely diagnosis is PLC.

PLC vs pityriasis rosea. Clinicopathological correlation is needed.

PLEVA as focal extravasted RBCs are seen. Pityriasis rosea should be clinically excluded

Another good day for you all. PlC is correct although clinicopathological correlation is necessary. Early erythema multiforme is an excellent differential diagnosis. The angulated parakeratosis (tea pot sign) is not seen which makes pityriasis rosea unlikely and in addition, in my experience interface change is not seen in this condition whereas mild spongiosis is often present.

Have a great weekend and thank you all for your comments this week.

The basic dermatopathology module (for beginners) is progressing well and this should prove really useful for those embarking on the discipline.

Basal vacuolar degeneration and red cell extravasation. Though not the classical example, can be compatible with PLC.
