06:30-07:30 Registration & Full Breakfast with the Exhibitors
07:30-07:40 Introductory Remarks & Welcome
07:40-08:40 Opening Keynote 1: Lipomatous tumous - evolving concepts
Dr. Jeanne Meis

Lipomatous tumors span a broad age range and have a wide morphologic spectrum. However, there are certain key histological features, particularly in the context of clinical information and imaging features, that narrow the differential diagnosis. The diagnosis in many cases can be further refined or confirmed with the application of appropriate molecular studies. A historical overview of concepts in lipomatous neoplasia is useful, as some concepts have evolved and even revolved (returned) with the recent molecular investigations.Objectives:

  1. Distinguish between lipoblasts and pseudolipoblasts and recognize the clinical contexts in which they occur.
  2. Determine when molecular studies such as FISH for MDM2 amplification or DDIT3 are needed to establish a diagnosis for treatment purposes.
  3. Recognize the variety of terminology and nomenclature for spindle cell lipomatous lesions as well as their clinical implications.
  4. Formulate a differential diagnosis of lipomatous lesions and their mimics based on morphology and imaging studies and apply molecular studies to arrive at the diagnosis.
  5. Recognize the wide variety of patterns seen in dedifferentatied liposarcoma and distinguish them from neoplastic mimics.

Target audience: The session will be valuable to pathology residents, pathology assistants, general and anatomic pathologists, and pathologists who specialize in the diagnosis of bone and soft tissue tumors.

08:40-09:30 Session 1: Nerve Sheath Tumors - Dr. Jodi Carter
09:30-10:20 Session 2: Immunohistochemistry of Soft Tissue Tumors: Tried & True and Some Things New - Dr. Bret Wehrli
10:20-10:50 Break in the Exhibit Hall
10:50-11:40 Session 3: Problematic (myo)fibroblastic tumors of Soft Tissue - Dr. Jeanne Meis

Fibroblastic and myofibroblastic lesions of soft tissue encompass the largest category of tumors in the current classification of soft tissue tumors.

Some of these tend to occur in certain patient populations in a specific clinical setting whereas others are idiopathic and without distinctive clinical features. Overlapping histological features are particularly problematic in this group of tumors. Knowledge of the limitations of biopsy sampling and judicious use of ancillary studies are key in optimizing rapid and accurate diagnosis. The primary focus of this lecture will be on the most common problematic issues with pseudosarcomas, new entities and decisive molecular studies, particularly when immunohistochemistry results are misleading or non-helpful.

Target audience: The session will be valuable to pathology residents, pathology assistants, general and anatomic pathologists, and pathologists who specialize in the diagnosis of bone and soft tissue tumors

10:50-11:40 Session 3: Core biopsy diagnosis of intra-abdominal and retroperitoneal lesions: Rolling in the Deep          - Dr. Jeanne Meis

Fibroblastic and myofibroblastic lesions of soft tissue encompass the largest category of tumors in the current classification of soft tissue tumors. Some of these tend to occur in certain patient populations in a specific clinical setting whereas others are idiopathic and without distinctive clinical features. Overlapping histological features are particularly problematic in this group of tumors. Knowledge of the limitations of biopsy sampling and judicious use of ancillary studies are key in optimizing rapid and accurate diagnosis. The primary focus of this lecture will be on the most common problematic issues with pseudosarcomas, new entities and decisive molecular studies, particularly when immunohistochemistry results are misleading or non-helpful.

Target audience: The session will be valuable to pathology residents, pathology assistants, general and anatomic pathologists, and pathologists who specialize in the diagnosis of bone and soft tissue tumors.

Objectives:

  1. Specify if a core biopsy is representative of the process in light of the imaging studies.
  2. Formulate a differential diagnosis based on precise location of lesion on imaging, past medical history and patient's age.
  3. Consider non-soft tissue entities in the differential diagnosis of retroperitoneal and intra-abdominal lesions.
  4. Distinguish when and which immunohistochemistry and molecular studies are appropriate in a given core biopsy.
  5. Determine when to refrain from overclassification of a biopsy.
11:40-12:30 Session 4: Vascular Tumors of Bone - Dr. Petur Nielsen

Case 1: Dr. Charlene Hunter
Case 2: What Kind of Muffin?
Drs Mariam Abbas, Tawny Hung & Kimberly WoodA term female middle eastern neonate was admitted to the Neonatal intensive Care Unit with multiple violaceous nodules that were noticed at birth. This presentation will go over the clinical and histologic work-up for such a case, as well as the common differential diagnoses to consider. Importantly, the collaboration and communication required between dermatology and pathology will be highlighted.     This presentation will be of value to residents in pathology and dermatology, general and anatomic pathologists, and dermatologists.Objectives:

  1. List the three most common clinical causes for a blueberry muffin neonate and summarize the typical clinical features for each.
  2. List the three most useful clinical laboratory tests.
  3. List the three most common dermal histiocytic proliferations to consider in children.
  4. List the three most helpful immunohistochemical stains in the histologic workup of dermal histiocytic proliferations.
  5. Explain the limitations of histologic diagnosis and why collaboration with the clinician is paramount in arriving at the correct diagnosis.
