Other studies show animals with similar injuries can recognize objects with which they are familiar, but, when the objects are presented in an unexpected context, they do not score well on recognition tests. Islands of memory
Patients with anterograde amnesia have trouble recalling new information and new autobiographical events, but the data are less consistent in regard to the latter. Medveds and Hirst recorded the presence of islands of memory – detailed accounts – that were described by such patients. The island memories were a combination of semantic and episodic memories. The researchers recorded patients giving long narratives with a fair amount of detail that resembled memories that the patients had prior to the trauma. The appearance of islands of memory could have something to do with the functioning of adjacent cortical areas and the neocortex. In addition, the researchers suspect that the amygdala played a role in the narratives. Notable cases
The most famous case reported is that of patient Henry Molaison, known as H.M., in March 1953. Molaisons chief complaint was the persistence of severe seizures and therefore had a bilateral lobectomy (both of his medial temporal lobes were removed). As a result, Molaison had bilateral damage to both the hippocampal formation and the perirhinal cortex. Molaison had average intelligence and perceptual ability and a decent vocabulary. However, he could not learn new words or remember things that had happened more than a few minutes earlier. He could remember anything from his childhood.
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
