Professor of Dermatology and Pathology

Physician Biography

I am a dermatologist and a dermatopathologist. Dermatopathology is a key part of dermatology - the correct diagnosis often rests on a careful correlation of clinical and microscopic findings, something that we do at Yale for all patients, but especially those with complex presentations. We can do this by reviewing prior biopsies, taking new biopsies, and also presenting patients at our weekly Grand Rounds.

Curriculum Vitae

Research Image 1

Squamous cell carcinoma. The lesion has a crateriform architecture. Cutaneous squamous cell carcinoma does not tend to self-resolve and rarely may metastasize.

Research Image 2

Keratoacanthoma. This lesion has a characteristic crateriform architecture. While standard treatment is to treat keratoacanthoma as a subtype of squamous cell carcinoma, true keratoacanthoma is a self-resolving tumor.
