What Causes Xanthoma Disseminatum When Suffering From Diabetes Insipidus?
Xanthoma disseminatum; Need more information
Detailed Answer:
Hello. Thanks for writing to us at healthcaremagic
I am Dr. Kakkar. I have gone through your query and I have also gone through the link (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC0000/)
I would like to gather more information from you regarding the query.
-Apart from treatment for diabetes Insipidus, is he on any other treatment?Let me know.
-How has his skin condition responded to the medications?
Xanthoma Disseminatum (XD) Or Montgomery's disease is a very rare disease.
In XD, there may be involvement of the skin (predominantly flexures), mucous membrane of eyes, upper respiratory tract, Central Nervous System (CNS) as well as rarely internal organ involvement like liver, spleen and bone marrow.
Skin involvement is characterized by extensive cutaneous and mucous membrane xanthomas in normolipidemic patients.
While skin disease is benign except for discomfort and disfiguring, upper respiratory tract involvement might lead to respiratory distress.
Lesions at critical anatomic sites like pituitary and intracranilal involvement may result in morbidity and mortality
Pituitary gland infiltration is common leading to Diabetes Insipidus in about 40% of XD patients
XD is a self limiting disease otherwise.
While for cutaneous lesions CO 2 Laser has been used with good results, other drugs that have been effective for skin involvement are azathioprine and cyclophosphamide.
Oral lipid lowering drugs have also been tried for cutaneous disease.
Surgery is an option for CNS involvement.

Treatment of Xanthoma disseminatum is challenging
Detailed Answer:
Hi.
No doubt, XD is a challenging case in dermatology. XD Cases are rare therefore there are no controlled trials for systemic therapy.
There are 3 clinical patterns of XD: A persistent form which is common, a less common progressive form with systemic involvement and a rare spontaneous regressive form.
*Underlying Diabetes Insipidus has been associated with the progressive form of the disease.
A reproducibly effective therapy is yet to be identified for XD.
The following have been used with variable success:
Systemic steroids (daily or pulse),
Azathioprine,
Cyclophosphamide,
Interferons,
Lipid Lowering agents.
However, none has been reported to be uniformly effective in the treatment of XD though they may halt the progression in progressive disease.
Recently 2-chlorodeoxyadenosine has been shown to be an effective option in inducing remission and long term control.
Diet is an option too.
These options may be used either alone or combined.
The combination of pulse systemic steroids, interferons and statins (lipid lowering agents) seems to have been effective and is a good therapeutic option.
What I would suggest that he may continue on lipid lowering agents along with 2 chlorodeoxyadenosine.
He should be thoroughly investigated (blood investigations and radiological investigations for any internal involvement).
Though CNS involvement is rare (<5%) but I hope he already has been investigated specifically for CNS involvement (apart from pituitary) with an MRI because that can be life threatening.
Surgery is an option if there is intracranial involvement. Oral steroids can be tried if there is diffuse CNS involvement and surgery is difficult.
Cutaneous and laryngeal involvement is amenable to surgery, electrocoagulation, Laser etc.
The prognosis of XD is usually good in most cases. However, it can be worse if vital organs (specially CNS) are involved.
