Interdigitating dendritic cell sarcoma

What it is

A rare dendritic cell tumor characterized by a neoplasm composed of spindle to ovoid cells with phenotypic features similar to those of interdigitating dendritic cells. Solitary lymph node involvement is common, although extranodal localization (in particular skin and soft tissue) has also been reported. Patients usually present with an asymptomatic mass, sometimes with systemic symptoms such as fatigue, fever, and night sweats. Generalized lymphadenopathy, splenomegaly, or hepatomegaly may be seen in rare cases. The clinical course is generally aggressive.

Disease

Prevalence figures describe populations, not individuals, and are often estimates from a single study. Where the figure is an incidence or a birth prevalence, it says so.

ICD-10 codes

ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.

Related health topics

Reached through the ICD-10 categories this disease is filed under, so these describe the broader group rather than this disease specifically.
