An extended form of toxic epidermal necrolysis with characteristics of destruction and detachment of the skin epithelium and mucous membranes involving more than 30% of the body surface area.

Patients should be admitted to an intensive care or burns unit as soon as the diagnosis is suspected. Prognosis is poor (mortality rate: 20-25%).

No other signs or symptoms of Stickler syndrome are present. Can be caused by mutation in the COL2A1 gene.	Associated morphology	True	Separation	Inferred relationship	Some	1
A rare acquired eye disease with characteristics of unilateral or bilateral abnormal fluid accumulation within the suprachoroidal space. This results in internal choroidal elevation in the absence of any known cause such as decreased intraocular tension, intraocular neoplasm, intraocular inflammation or nanophthalmos. Patients typically present a protracted, relapsing-remitting course of visual acuity loss and fundus examination shows annular celio-choroidal detachment and shifting, serous retinal detachment.

A rare genetic non-syndromic developmental defect of the eye disorder with the association of posterior microphthalmia, retinal dystrophy compatible with retinitis pigmentosa, localised foveal schisis and optic disc drusen. Patients present high hyperopia, usually adult-onset progressive nyctalopia and reduced visual acuity and on occasion acute-angle glaucoma. Caused by homozygous or compound heterozygous mutation in the MFRP gene on chromosome 11q23.	Associated morphology	True	Separation	Inferred relationship	Some	3
