Inverted pyramidal biopsy.
We describe a biopsy technique that is simple, rapid, and effective for numerous cutaneous lesions. The inverted pyramidal biopsy (IPB) creates an acute geometric tissue defect with an apex located in the dermis. A cosmetically pleasing result, while still providing adequate tissue to render a histologic description and diagnosis, is obtained. The technique can also be employed to remove a host of benign lesions, including dermatofibroma, fibrous papules, and chalazion, among others.
