<span style="color:#0070C0">(General Instructions – The focus of these pages is the clinically significant genetic alterations in each disease type. This is based on up-to-date knowledge from multiple resources such as PubMed and the WHO classification books. The CCGA is meant to be a supplemental resource to the WHO classification books; the CCGA captures in a continually updated wiki-stye manner the current genetics/genomics knowledge of each disease, which evolves more rapidly than books can be revised and published. If the same disease is described in multiple WHO classification books, the genetics-related information for that disease will be consolidated into a single main page that has this template (other pages would only contain a link to this main page). Use [https://www.genenames.org/ <u>HUGO-approved gene names and symbols</u>] (italicized when appropriate), [https://varnomen.hgvs.org/ <u>HGVS-based nomenclature for variants</u>], as well as generic names of drugs and testing platforms or assays if applicable. Please complete tables whenever possible and do not delete them (add N/A if not applicable in the table and delete the examples); to add (or move) a row or column in a table, click nearby within the table and select the > symbol that appears. Please do not delete or alter the section headings. The use of bullet points alongside short blocks of text rather than only large paragraphs is encouraged. Additional instructions below in italicized blue text should not be included in the final page content.

==Epidemiology / Prevalence==
 
*BPDCN is rare, estimated to represent < 1% of all hematologic malignancies<ref name=":0" />.
 
*The incidence of BPDCN in the USA: 0.04 cases per 100,000 individuals<ref name=":2">{{Cite journal|last=Khoury|first=Joseph D.|date=2018|title=Blastic Plasmacytoid Dendritic Cell Neoplasm|url=https://www.ncbi.nlm.nih.gov/pubmed/30350260|journal=Current Hematologic Malignancy Reports|volume=13|issue=6|pages=477–483|doi=10.1007/s11899-018-0489-z|issn=1558-822X|pmid=30350260}}</ref>.
 
*BPDCN has no known racial or ethnic predilection.
 
*Though BPDCN can occur at any age, it more commonly occurs in elderly patients with a mean/median patient age at diagnosis of 61-67 years<ref name=":0" /><ref name=":3">{{Cite journal|last=Kerr|first=Daniel|last2=Zhang|first2=Ling|last3=Sokol|first3=Lubomir|date=2019|title=Blastic Plasmacytoid Dendritic Cell Neoplasm|url=https://www.ncbi.nlm.nih.gov/pubmed/30715612|journal=Current Treatment Options in Oncology|volume=20|issue=1|pages=9|doi=10.1007/s11864-019-0605-x|issn=1534-6277|pmid=30715612}}</ref>.

<blockquote class='blockedit'>{{Box-round|title=v4:Clinical Features|The content below was from the old template. Please incorporate above.}}
Typical BPDCN patients may have two stages<ref name=":0" />:
o  First stage: affects the skin , usually contained or indolent
o  Second stage:  rapid leukemic spread and multi-organ involvement that eventually leads to death<ref name=":0" />.
</blockquote>
==Sites of Involvement==
*Multiple sites are frequently involved by BPDCN. The three most common are the skin (in 60–100% cases), followed by the bone-marrow and peripheral blood (in 60–90% of cases), and thirdly the lymph nodes (in 40–50% of cases)<ref name=":0" />.
*Upon diagnosis, the central nervous system (CNS) is also frequently found to be involved, and up to one third of patients have CNS involvement at relapse<ref name=":2" />.
==Morphologic Features==
*BPDCN is commonly characterized by a diffuse, monomorphous infiltrate of small or medium-sized blasts<ref name=":0" />.
*The morphology of the neoplastic cells is similar to lymphoblasts or myeloblasts:  high N: C ratio, eccentrically located nucleus, fine chromatin, a prominent nucleolus and scant amphophilic cytoplasm<ref name=":0" />.
*Mitoses are variable in number, and the Ki-67 rate ranges from 20 to 80%<ref name=":0" />.
*Necrosis may present.

|<span class="blue-text">EXAMPLE:</span> Fusions result in constitutive activation of the ''ALK'' tyrosine kinase. The most common ''ALK'' fusion is ''EML4::ALK'', with breakpoints in intron 19 of ''ALK''. At the transcript level, a variable (5’) partner gene is fused to 3’ ''ALK'' at exon 20. Rarely, ''ALK'' fusions contain exon 19 due to breakpoints in intron 18.
