CASE SUBMISSION GUIDELINES

The workshop panel will collate and discuss all cases submitted to the Workshop. All cases will be organized into eight sessions using the topics chosen by the submitter in the online system but may be rescheduled at the discretion of the Workshop Panel. Approximately 40 cases (4 or 5 cases per session) will be presented during the meeting. Early submissions are strongly encouraged.

Alert!  Online Case Submission Opens: November 1, 2022

Please note the following guidelines for case submission. The online submission system will automatically enforce these guidelines:

  • Case text is limited to 3,500 characters
  • Please structure your case as follows:
    • Clinical Information
    • Description of Submitted Tissues
    • Details of Microscopic Findings
    • Immunophenotype
    • Cytogenetics
    • Molecular Studies
    • Proposed Diagnosis/ses
    • Interesting Features of Case
  • Molecular characterization with data interpretation is offered free of charge to the workshop participants for inclusion in their presentations in cases of AILT and T-cell lymphomas with a follicular helper T cell phenotype, PTCL-NOS, Lennert lymphoma and nodal cytotoxic PTCL.
  • Tissue Submission:
    • Each case should include the submission of (2) two H&E slides of representative tissue per specimen and 20 unstained slides. The H&E slides will be used for any required additional review by the planning committee, and they may also be made available to all workshop attendees in the form of digital whole slide imaging, if your case is selected for individual presentation. The unstained slides will be used to perform immunohistochemical studies, as needed, to further characterize the immunophenotype of the neoplasm (e.g PD1, ICOS, IDH2R172K, TBX21, CXCR3, GATA3 and CCR4) and to extract RNA or DNA to perform the molecular studies if applicable to the case. Please check mark the box if you agree to proceed with the molecular analysis of your case if selected.
  • Please upload your slides (max. 10 MB, PowerPoint) using the provided template.
  • All cases must contain original work and content that has not been published in a peer-review journal.
  • The case submission fee is 35 USD.
  • Cases must be submitted in English. Please check spelling and grammar carefully.
  • For the skin cases, it is highly recommended to provide clinical pictures of the lesions and a detailed clinical history. This will facilitate the review of the case by the panelists.
