Pathologists and hematologists/oncologists are encouraged to submit cases to the Joint CSHP-EA4HP-SH Workshop 2024. The Scientific Panel of the Joint Workshop will review all submitted cases, and select cases for platform presentations at the Workshop. Case submission begins on May 8th, 2023, and ends on Sept 11th, 2023 (12:00 AM, Beijing time UTC+8).Notifications for the selected case presentations will be sent in November, 2023. 

The Joint Workshop is seeking the following case types and features:

1). Reactive proliferations of macrophages and dendritic cells that mimic histiocytosis;

2). Hemophagocytic lymphohistiocytosis (HLH) including cases secondary to hematolymphoid neoplasms;

3). Langerhans cell and other histiocytoses (e,g, ECD, JXG, RDD, MRH, ALK+ histiocytosis), including cases with features overlapping between different entities (so-called "mixed histiocytoses") (cases of solitary JXG and reticulohistiocytoma excluded).

4). BPDCN and plasmacytoid dendritic cell proliferations associated with myeloid neoplasms;

5). Malignant histiocytosis (e.g. histiocytic sarcoma, follicular dendritic cell sarcoma, Langerhans cell sarcoma, interdigitating dendritic cell sarcoma etc), including cases illustrating issues in assigning cell of origin and difficulties in assessing malignant potential."

The Workshop will focus on cases with one or more of the following features:

1). Exemplary demonstration of various subtypes of histiocytic/dendritic cell proliferations and neoplasms using multidisciplinary correlations;

2). Borderline cases illustrating morphologic and immunophenotypic overlaps of various subtypes of histiocytic/dendritic cell neoplasm; 

3). Transdifferentiation of histiocytic/dendritic cell neoplasms from the associated lymphomas/leukemias;

4). Rare histiocytic/dendritic cell neoplasms with unusual clinical, morphologic, immunophenotypic, or genetic features.

1. One completed Case Submission Form; *Download Case Submission Form here

2. One PowerPoint Presentation containing representative studies/images (no more than 20 ppt slides, maximum size 30MB) *download the Joint Workshop PPT file template here;

3. One whole slide scanned image of a representative H&E slide, scanned at 40x magnification. If you don’t have access to a scanner, please see the instructions below. 

Instructions for Case Submitters who do not have access to a slide scanner

If you don’t have a scanner, please send one representative H&E slide to the JW, so that the slide can be scanned for the Panel Review.  Please send your slide along with your information (your full name, case number, title, Institution, and address) to: Jianfeng Wu，MD, Department of Pathology, Xijing Hospital, No. 127, Changle West Road, Xi’an, Shaanxi Province 710032, P.R. China, Tel: +86-157-0296-9486, and email: kobewoo1989@163.com.

*Note:  Additional studies/material may be requested by the Panelists during Panel Review. In such circumstances, the Panelists will contact the case submitters directly. If indicated, additional studies including IHCs, FISH, and molecular studies (B-/T-cell gene rearrangement studies, Sanger sequencing and NGS) may be performed by the JW.

Step 1. Compress the completed Case Submission Form and PowerPoint file into one file; 

Step 2. Upload the compressed file, and submit. Wait for an email receipt of the JW, where a Case Number will be assigned to your case, before proceeding to Step 3.

Step 3. Once you have the JW Case Number, rename your whole slide image file as “case number+space+your last name” (for example, 153 Jones). Then, upload the renamed whole slide image file using one of the two options below:

Option One via DropBox:

1). You would need to establish an account if you do not have an account with Dropbox.

2). Copy and paste the link into your internet browser: (https://www.dropbox.com/scl/fo/ne9o1cdd8xfk2c00pl25q/h?dl=0&rlkey=6dkwqdlthiwafsvsg62b8zu4w  )

3). You would need follow the Dropbox email verification process to complete the account setup if you don’t have a Drobox account.

4). Select the folder ‘CSHP-EA4HP-SH 2024 case submission’, then wait for permission from the JW2024 administrators (*usually takes 20 minutes between 7:30a.m-11:30p.m, Beijing time UTC+8; Outside the time frame, you may wait to the next day);

5). Once you have the permission, upload your renamed whole slide image.

Option Two via Cloud Drive（you frequently-used）

1)    Upload your renamed whole slide image to Cloud Drive;

2)    Email the share/download link to kobewoo1989@163.com.
