Spitzoid Neoplasm Repository

Yale School of Medicine’s Spitzoid Neoplasm Repository is an international biospecimen and data collection bank, used to conduct research to better understand, diagnose, and treat Spitzoid neoplasms. more…

The Spitzoid Neoplasm Repository is an invaluable resource for researchers looking for specific markers and/or genetic abnormalities in neoplastic cells. The Repository facilitates all angles of research, including immunohistochemical, molecular, genetic and other studies.

Researchers and collaborators within the Yale Medical Group as well as researchers from other institutions can participate. The results of these studies will be correlated with the clinical information in order to correctly differentiate and categorize Spitzoid neoplasms. This will increase our knowledge and lead to better understanding, diagnosis, and treatment of Spitzoid neoplasms in the future.

Our Goals


Our goal is to better understand Spitzoid neoplasm biology and reliably diagnose and treat Spitzoid neoplasms.

What is a Spitzoid Neoplasm?

Spitzoid neoplasms include a spectrum of skin lesions ranging from completely benign “typical” Spitz nevi to lesions that are called “atypical” Spitz nevi, which do not precisely conform to the category of a “typical” Spitz nevus.
