Buschke–Ollendorff syndrome

Buschke–Ollendorff syndrome (BOS) is a rare genetic disorder associated with LEMD3. It is believed to be inherited in an autosomal dominant manner.[5] It is named for Abraham Buschke and Helene Ollendorff Curth,[6] who described it in a 45-year-old woman. Its frequency is almost 1 case per every 20,000 people, and it is equally found in both males and females.[4]

Buschke–Ollendorff sign
Other namesDermatofibrosis lenticularis disseminata[1]
Buschke–Ollendorff syndrome has an autosomal dominant pattern of inheritance.
SymptomsOsteopoikilosis, bone pain[2]
CausesMutations in the LEMD3 gene.[2]
Diagnostic methodX-ray, ultrasound[3]
TreatmentSurgery for hearing loss(or complications)[4]

Signs and symptoms
Osteopoikilosis

The signs and symptoms of this condition are consistent with the following (possible complications include aortic stenosis and hearing loss[2][4]):

Pathogenesis

Buschke–Ollendorff syndrome is caused by one important factor: mutations in the LEMD3 gene (12q14), located on chromosome 12.

Among the important aspects of Buschke–Ollendorff syndrome condition, genetically speaking are:[7][8][9]

Bone Cells
  • LEMD3 (protein) referred also as MAN1, is an important protein in inner nuclear membrane.
  • LEMD3 gene gives instructions for producing protein that controls signaling for transforming growth factor-beta.
  • LEMD3 gene helps in the bone morphogenic protein pathway
  • Both of the above pathways help grow new bone cells
  • BMP and TGF-β pathways controls SMADs proteins, which then bind to DNA
  • LEMD3 once mutated, causes a reduction of the protein, which in turn causes excess of the above two pathways.

Diagnosis
Microscope with stained slide (histological specimen)
Histopathology of BOS[10]

The diagnosis of this condition can be ascertained via several techniques one such method is genetic testing, as well as:[2][3]

Differential diagnosis

The differential diagnosis for an individual believed to have Buschke–Ollendorff syndrome is the following:[3]

Treatment

In terms of the treatment of Buschke–Ollendorff syndrome, should the complication of aortic stenosis occur then surgery may be required.[4]

Treatment for hearing loss may also require surgical intervention.[4]
