There Is No Spoon

I'm sorry this posted late. This will be the only case this week, but we should be regularly scheduled starting next Monday.

This skin lesion is an asymptomatic papule or nodule and is firm to the touch. Depression of one side of the lesion leads to elevation of the other side. It is most common in childhood and adolescence.

Challenge: What is it?

This is a pilomatricoma (pilomatrixoma, calcifying epithelioma of Malherbe), a benign skin neoplasm derived from matrical cells of the hair follicle. The firmness is due to calcification. The teeter-totter sign is described.
