IgA pemphigus is a subtype of pemphigus with two distinct forms:

Subcorneal pustular dermatosis (also known as Sneddon–Wilkinson disease and pustulosis subcornealis) is skin condition that is a rare, chronic, recurrent, pustular eruption characterized histopathologically by subcorneal pustules that contain abundant neutrophils. : 203  This is distinct from and not to be confused with subcorneal pustular dermatosis type of IgA pemphigus. Sneddons syndrome, also known as Ehrmann-Sneddon syndrome, is also a different syndrome. Intraepidermal neutrophilic IgA dermatosis is characterized histologically by intraepidermal bullae with neutrophils, some eosinophils, and acantholysis. : 465

Ventricular aneurysms are one of the many complications that may occur after a heart attack. The word aneurysm refers to a bulge or pocketing of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum, or within the aorta. In the heart, they usually arise from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. This, in turn, may block the passageways leading out of the heart, leading to severely constricted blood flow to the body. Ventricular aneurysms can be fatal. They are usually non-rupturing because they are lined by scar tissue. A left ventricular aneurysm can be associated with ST elevation. Signs and symptoms
Ventricular aneurysms usually grow at a very slow pace, but can still pose problems. Usually, this type of aneurysm grows in the left ventricle. This bubble has the potential to block blood flow to the rest of the body, and thus limit the patients stamina. In other cases, a similarly developed pseudoaneurysm ("false aneurysm") may burst, sometimes resulting in the death of the patient. Also, blood clots may form on the inside of ventricular aneurysms, and form embolisms. If such a clot escapes from the aneurysm, it will be moved in the circulation throughout the body. If it gets stuck inside a blood vessel, it may cause ischemia in a limb, a painful condition that can lead to reduced movement and tissue death in the limb.
