Solving Problems of Lipomatous Tumors

Sunday, March 18, 2018, 1:30 -5:00 PM

Session Credits:

3 CME and 3 SAMs

Moderators:

Markku Miettinen, National Institutes of Health, Bethesda, MD
Jean-Michel Coindre, University of Bordeaux, France

Course Description:

The program of lipomatous tumors is centered on practical diagnostic topics many of which are met daily in the clinical practice. Atypical lipomatous tumor vs. lipoma is one of the most frequent challenges in soft tissue diagnosis, and will be discussed from histological and molecular perspective. Dedifferentiated liposarcoma is a great mimicker in tumor pathology, and its many morphologic manifestations and their clinical significance will be discussed. Spindle cell lipoma is an infrequent type of lipoma occurring in soft tissue and skin, and atypical spindle cell lipomatous tumors, a newer lipomatous tumor entity will be covered in dedicated presentations. Molecular testing will help diagnosing myxoid liposarcoma and lipoblastoma, and specific gene rearrangements in these tumors will be highlighted in practical terms. Newer immunohistochemical markers that have some promise in evaluation in liposarcoma diagnosis will be presented. Enigmatic lipomatous tumors of bone are also covered in a dedicated presentation.

Learning Objectives:

Upon completion of this educational activity, the learner will be able to:

  • Recognize the different clinicopathological and histologic forms of well-differentiated and dedifferentiated liposarcoma.
  • Utilize genetic and immunohistochemical studies in the diagnostic evaluation of benign and malignant lipomatous tumors.
  • Understand the pathologic manifestations of lipomatous tumors of bone.

Continuing Medical Education and Maintenance of Certification

This activity has been planned and implemented in accordance with the accreditation requirements and policies of the Accreditation Council for Continuing Medical Education (ACCME) through the joint providership of The United States and Canadian Academy of Pathology and International Society for Bone and Soft Tissue Pathology. The United States and Canadian Academy of Pathology is accredited by the ACCME to provide continuing medical education for physicians.

The United States and Canadian Academy of Pathology designates this live activity for a maximum of
3 AMA PRA Category 1 Credits™. Physicians should claim only the credit commensurate with the extent of their participation in the activity.

The USCAP is approved by the American Board of Pathology (ABP) to offer Self-Assessment credits (SAMs) for the purpose of meeting the ABP requirements for Maintenance of Certification (MOC). Physicians must take and pass the post-test in order to claim SAMs credit.

Physicians can earn a maximum of 3 SAM credit hours.
