Drusen, from the German word for node or geode (singular, "Druse"), are tiny yellow or white accumulations of extracellular material that build up between Bruch's membrane and the retinal pigment epithelium of the eye. The presence of a few small ("hard") drusen is normal with advancing age, and most people over 40 have some hard drusen. [1]
Plantar fascial fibromatosis, also known as Ledderhose's disease, Morbus Ledderhose, and plantar fibromatosis, is a relatively uncommon [2] non-malignant thickening of the feet's deep connective tissue, or fascia. In the beginning, where nodules start growing in the fascia of the foot, the disease is minor.
Leber congenital amaurosis (LCA) is a rare inherited eye disease that appears at birth or in the first few months of life. [2]It affects about 1 in 40,000 newborns. [1] LCA was first described by Theodor Leber in the 19th century.
Pachyonychia congenita follows an autosomal dominant pattern of inheritance, which means the defective gene is located on an autosome, and only one copy of the gene is required to inherit the disorder from a parent who has the disorder. On average, 50% of the offspring of an affected person will inherit the disorder, regardless of sex.
In children, optic disc drusen are usually buried and undetectable by fundoscopy except for a mild or moderate elevation of the optic disc. With age, the overlying axons become atrophied and the drusen become exposed and more visible. They may become apparent with an ophthalmoscope and some visual field loss at the end of adolescence.

Juvenile plantar dermatosis is a condition usually seen in children between the ages of 3 and 14, and involves the cracking and peeling of weight bearing areas of the soles of the feet. [ 1 ] One of the earliest descriptions was made by British dermatologist Darrell Wilkinson .
Pes cavus can occur from four primary causes: neurological conditions, trauma, undertreated clubfoot, or idiopathic with other underlining conditions. [9]Bilateral presentation (i.e., in both feet) often occurs due to a hereditary or congenital source, whereas a unilateral presentation (i.e., in one foot) is often the result of trauma.
