Clinical definition (Orphanet)

A rare dendritic cell tumor characterized by a neoplasm composed of spindled to ovoid cells with phenotypic features similar to those of normal indeterminate cells. The tumor cells consistently express S100 protein and CD1a, while langerin, specific B- and T-cell markers, CD30, the histiocytic marker CD163, and the follicular dendritic cell markers CD21, CD23, and CD35 are negative. Birbeck granules are absent on ultrastructural examination. Patients typically present with multiple papules, nodules, or plaques of the skin. Primary lymph node or splenic involvement is less common. Systemic symptoms are usually absent. The clinical course is highly variable.

Research stages

Trial readiness signals

Where this condition sits on an open-data research pipeline — not how close a treatment is, and not medical advice. Empty stages often mean “not in these databases under this Mondo ID,” not “impossible.”

Biology

Genes and phenotypes

Gene–disease validity from GenCC, plus phenotypes and animal models joined from Monarch Initiative via Mondo ID — not a clinical diagnosis aid.

Do we know what causes it?

Not yet — the cause hasn't been pinned down in GenCC.

No strong gene–disease assertion joined for this Orphanet entity.

Phenotypes (Monarch / HPO)

Not enriched in this build — Monarch phenotype joins were not run for this record.

Literature

Is anyone studying this?

1,379

1,379 papers have been published on this condition. That is a real research literature — still far smaller than common diseases (breast cancer: over 700,000 papers). Median papers in the last 10 years for a rare disease in this dataset (publications denominator n=5449) is 41.

1,379 papers since the earliest indexed year in this search — median last-10-year count for a rare disease in this dataset is 41 (publications denominator n=5449).

interventional trials for this specific condition

2 interventional trials matched this specific condition name; 1 currently recruiting in our sample. 1,653 trials are registered for sarcoma, the broader category — shown separately because they may or may not enrol this specific subtype.

Data as of 27 July 2026

2 interventional trials — more than 73% of diseases in the trials denominator have none at all (5114 of 7003; this disease is at the 82.4th percentile).

Where to find support

We do not yet link condition-specific patient organisations. These umbrella groups support undiagnosed and ultra-rare families:

India — NPRD

Last verified 2026-07-26

This ORPHAcode is not on our curated NPRD list (direct or Mondo-parent match). That does not decide clinical eligibility; families in India should ask a notified Centre of Excellence about current coverage.

Hand-curated for this project. ORPHAcode mappings are best-effort and may be incomplete or imprecise for umbrella categories. Parent (Mondo) matches mean the policy lists a broader category — confirm eligibility with a Centre of Excellence. Financial entitlements summarised from public policy statements and may change. This is not official government guidance.

How we counted this

Europe PMC query (preferred label + any corrected label + Orphanet and Mondo exact synonyms, stoplisted; unioned with resolved MeSH labels when available). UMLS / OMIM / NCIT cross-references are stored on the overview but are not added to the query string.

ClinicalTrials.gov query (quoted phrases + MeSH via query.cond, plus recall-expansion terms when used):

Interventional trials matched via: phrase (mesh = registered under a MeSH descriptor no name phrase would catch; recall-expansion = gene / selected parent terms used only for trials).

Confidence reasoning

  • Preferred label is multi-word and distinctive
  • No synonyms dropped by stoplist
  • No label/synonym collisions with other diseases in this corpus
  • Publication count (1379) is extremely high with unknown/missing prevalence — treat as possible over-matching, not proven research intensity
