ORPHA:319303Disease
Also called Chromophobe renal cell adenocarcinoma
What it is
Chromophobe renal cell carcinoma is a rare subtype of renal cell carcinoma, originating from the intercalating cells of the collecting ducts and macroscopically manifesting as a well-circumscribed, highly lobulated, solid tumor that is usually diagnosed at an early stage. It is frequently asymptomatic, or may present with nonspecific symptoms, such as weight loss, fever or fatigue. The classic presentation observed in renal tumors (hematuria, flank pain and palpable mass) is occasionally observed and usually indicates an advanced stage of the disease. It is most frequently sporadic however, several familial cases, associated with Birt-Hogg Dubé syndrome, have been described.

Orphanet records these for the broader condition rather than for this specific form. They are a starting point, not a figure for this subtype — subtypes often differ, and some are defined by being rarer than the condition they sit under.
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.
