Greetings!

It was wonderful meeting so many of you at our recent hospital and community presentations. If there are topics that you would like to see covered in our newsletters, please do not hesitate to contact us.

Please check out our new section, Dermatopathology Differential Diagnosis.

We would like to update and alert you to these two newly described entities which the Institute has published.

Discohesive Malignant Melanoma Simulating a Bullous Dermatoses. J Cutan Pathol 2009;Feb 36(2): 274-279

This variant of melanoma, described by us, demonstrates the sometimes difficult task of separating neoplastic processes from inflammatory. The melanomas in our series resembled pemphigus vegetans and pemphigus vulgaris.

Amelanotic Malignant Melanoma in Situ: A Histopathologic Mimic of Benign Skin Lesions. Presented at the International Society of Dermatopathology Annual Meeting. March 5, 2009. San Francisco.

This new variant of melanoma in situ was just reported by us at the recent International Society of Dermatopathology. We identified 10 cases after a retrospective review of 444 cases of melanoma in situ (lentigo maligna). While the epidemiological profile is similar to other cases of lentigo maligna, in only 3 of the cases was a diagnosis of lentigo maligna suspected. On histopathological examination, the junctional melanocytes were small and had little to absent melanin pigment. The diagnosis was confirmed by staining with the Melan-A antibody.

Thank you.
