Moreover, pathological changes such as amyloid plaques and agminated
tau protein in regions of entorhinal cortex, parahippocampal gyrus, and subiculum in the medial temporal lobes can be tracked in MCI as well, although it may be not that severe compared with AD .
The differential diagnosis for agminated
blue nevi includes segmental melanocytic nevi, melanoma, and other agminated
melanocytic nevi: benign melanocytic nevi, atypical or dysplastic nevi, and speckled lentiginous nevi (nevus spilus).
On physical examination, there were numerous well-circumscribed, agminated
, soft, pink-colored papules on the upper back, right forearm, and dorsum of the left hand (Figure 1).
or herpetiform configurations were not present.
Differential diagnoses included a pigmented epithelioid melanocytoma, an agminated
Spitz nevus, or a "low-grade" melanoma (Clark's level III, Breslow thickness 3.7 mm).
