Rossitza Lazova MD

Associate Professor of Dermatology and of Pathology; Director, Yale Dermatopathology Fellowship

Research Interests

Spitz nevi; Spitzoid melanocytic neoplasms; Malignant melanoma; Melanocytic nevi on special anatomic sites; Atypical Spitzoid neoplasms


Research Summary

My main interest is in Spitz’s nevi, Spitzoid malignant melanomas, and Atypical Spitzoid melanocytic neoplasms. Other interests of mine are melanocytic nevi on special anatomic sites and their histologic characteristics and malignant melanoma. I am also interested in melanomas with heavily pigmented and multinucleated melanocytes, presumably hybrids with melanophages.

Extensive Research Description

My main interest is in melanocytic lesions, particularly malignant melanoma, Spitzoid malignant melanoma, Spitz’s nevi, and Atypical Spitzoid neoplasms. I am also interested in melanomas with heavily pigmented and multinucleated melanocytes, presumably hybrids with melanophages.
