Pili multigemini, also known as "compound hairs," is a malformation characterized by the presence of bifurcated or multiple divided hair matrices and papillae, giving rise to the formation of multiple hair shafts within the individual follicles. Description
The name describes a condition where several separate hair fibers bunch together and emerge from the skin through a single hair canal. Pathology shows that deep in the skin several dermal papilla are closely situated with each producing a fiber, but these separate hair follicle bulbs combine into one hair canal towards the skin surface. Folliculitis can sometimes be associated with this condition. Treatment
Electrolysis will permanently remove pili multigemini. Depilating laser treatment has been suggested to improve symptomatic pili multigemini. See also

Cerebral amyloid angiopathy (CAA) is a form of angiopathy in which amyloid beta peptide deposits in the walls of small to medium blood vessels of the central nervous system and meninges. The term congophilic is sometimes used because the presence of the abnormal aggregations of amyloid can be demonstrated by microscopic examination of brain tissue after staining with Congo red. The amyloid material is only found in the brain and as such the disease is not related to other forms of amyloidosis. Signs and symptoms
CAA is associated with brain hemorrhages, particularly microhemorrhages. Since CAA can be caused by the same amyloid protein that is associated with Alzheimers dementia, brain bleeds are more common in people who have a diagnosis of Alzheimers disease. However, they can also occur in those who have no history of dementia. The bleeding within the brain is usually confined to a particular lobe and this is slightly different compared to brain bleeds which occur as a consequence of high blood pressure (hypertension) – a more common cause of a hemorrhagic stroke (or bleeding in the brain). Causes
CAA has been identified as occurring either sporadically (generally in elderly populations) or in familial forms such as Flemish, Iowa, and Dutch types. In all cases, it is defined by the deposition of amyloid beta (Aβ) in the leptomeningal and cerebral vessel walls.
