2015 Annual Meeting

SC40-Situational Awareness on the Melanocytic Battlefield

2015 Annual Meeting

Room CC 207, March 26 2015, 8:00am to 11:30am

Steven Tahan, Alireza Sepehr, May P. Chan

Educational Objective

LAST PRESENTATION This course is designed to bring to light situational and site-specific changes that influence the histologic features of melanocytic lesions using a case-based approach. Topics include the influence of age, anatomic site, hormonal status, immunologic response, irritation effect, prior biopsy, and systemic treatment. Awareness of these effects can dramatically alter diagnostic interpretation of the histologic features. Specific entities that will be discussed include acral nevus, genital lentiginosis, flexural-site nevus, congenital nevus with proliferative nodule, nevus in pregnancy, halo nevus, nevoid melanoma, epithelioid cell melanocytic atypia, spindle and epithelioid cell lesions, sclerosing melanocytic nevus, desmoplastic melanoma, melanocytic lesions with fibrosis, de novo lentiginous melanocytic proliferation, lentiginous melanoma, deep penetrating nevus, and neurocristic hamartoma. The overall objective of this course is to improve diagnostic accuracy of melanocytic lesions for improved patient outcome. Surgical Pathologists, Dermatopathologists, and trainees would benefit most from this course. Pre-registrants will be able to view advance study material prior to the meeting on the USCAP website. A comprehensive syllabus will be available online prior to the course. After the meeting, PowerPoint presentations will be provided to be posted on the USCAP Website to course registrants. Upon completion of this educational activity, the participants are expected to:

  1. Acquire heightened awareness of situational and site-specific changes that influence the histologic features of melanocytic lesions;
  2. Identify key features that point to malignancy in nevoid melanocytic lesions;
  3. Be able to define epithelioid cell atypia and its significance;
  4. Understand the diagnostic significance of sclerosis and fibrosis in melanocytic lesions;
  5. Understand the concept of de novo lentiginous melanocytic proliferations and early lentiginous form of melanoma-in-situ;
  6. Improve recognition of the deep penetrating nevus and its differential diagnosis;
  7. Gain familiarity with the entity of neurocristic hamartoma.
