Q

acantholysis

A

a large papule over 1 cm; a circumscribed domed lesion raised above the level of the epidermis; often extends into the dermis

33
Q

papule

A

circrumscribed palpable elevation of skin less than 1 cm in diameter, usually due to cellular infiltration or proliferation, inflammatory or neoplastic
