Statement of problem as requested or initially identified
This primitive concept has a single, stated, fully-defined parent of |Benign neoplasm of bone (disorder)|. It is often benign, but there have been extremely rare cases of malignant transformation. Is it certain this is benign indeed?
Malignant degeneration (chondrosarcoma, fibrosarcoma, etc.) was found in 12 per cent of the solitary chondromas and in 32 per cent of the multiple chondromas and chondromatosis involving the bones elsewhere than in the hand.
The malignant transformation of chondromatosis is a frequent occurrence, but chondromatosis itself is rare.
Also, there are instances of extraarticular chondromatosis, so is it certain this concept describes just bone?
Chondromatosis of the joints is a rare condition. Only three cases were found in the extremely rich material of the orthopedic department of the State University of Iowa.
A case of chondromatosis of the choroid plexus of the brain in a 19 year old woman presenting with focal seizures is reported.
ICD-10 classifies this concept as “Neoplasm of uncertain or unknown behaviour of bone and articular cartilage”.
ICD-11 classifies this concept as "Osseous and chondromatous neoplasm, uncertain whether benign or malignant".
There are no stated relationships. There are two inferred relationships:
Finding site = Bone structure,
Associated morphology = Neoplasm, benign.
Adding |Chondromatosis (morphologic abnormality)| fully-defines the concept, but this is not the ideal way to define a concept. However, the parent to |Chondromatosis (morphologic abnormality)| is |Osseous AND/OR chondromatous neoplasm (morphologic abnormality)|.
Concept original release date is 20020131.
Relevance to International edition
Internationally relevant – Chondromatosis is in the international edition of SNOMED CT.
Related changes impacted by this content development request
240207006 |Synovial chondromatosis (disorder)| needs the Associated morphology attribute added with |Synovial chondromatosis (morphologic abnormality)|. This can be placed into a relationship group with the current finding site. It also needs the parent to be changed to closest proximal primitive. It can then be changed to fully-defined status.
Agreed scope statement
The scope is 302861008|Chondromatosis (disorder)| and 240207006 |Synovial chondromatosis (disorder)|.
Identify additional changes
None identified.
Solution proposed
For Chondromatosis:
Change the stated, defined parent to the proximal primitive parent |Disease|.
Add an associated morphology of |Chondromatosis (morphologic abnormality)|.
Make the concept’s status fully defined.
For Synovial chondromatosis:
Change the stated, defined parent to the proximal primitive parent |Disease|.
Add |Synovial chondromatosis (morphologic abnormality)| into a relationship group with the current finding site of |Synovial membrane structure|.
Fully-define the concept.

Impact assessment
These two conditions will be fully-defined and properly classified. Chondromatosis will no longer be modeled as a benign neoplasm of bone but will infer a parent of |Neoplastic disease|.
Risk assessment
The modelling will remain incorrect. Inaction will continue the differences in how these terms are defined by SNOMED CT and the International Classification of Diseases.
