Monocyte- and macrophage-related cutaneous conditions are characterized histologically by infiltration of the skin by monocyte or macrophage cells, [10] often divided into several categories, including granulomatous disease, [83] histiocytoses, [84] and sarcoidosis.
The deadly bacteria linked to recalled eyedrops causing infection and blindness had never been seen in the U.S. until 2022, according to the Centers for Disease Control and Prevention. It has ...
Pseudoexfoliation syndrome, often abbreviated as PEX [1] and sometimes as PES or PXS, is an aging-related systemic disease manifesting itself primarily in the eyes which is characterized by the accumulation of microscopic granular amyloid-like protein fibers. [2] Its cause is unknown, although there is speculation that there may be a genetic ...
These associated findings are common due to the underlying diseases causing these manifestations seen in the eyes. Because of the use of cotton wool spots more as an indicator of other systemic diseases, Mcleod had proposed that the taxonomy of the terms 'cotton wool spot' should be changed to something else to help better understand its true ...
