Trichophyton concentricum causes Malabar itch, a skin infection consisting of an eruption of a number of concentric rings of overlapping scales forming papulosquamous patches.
Nigiri sushi is a type of Japanese dish made with sushi rice and fresh fish. The sushi rice is hand formed into a small clump, and the fish is sliced and pressed on top of it. In some cases, nigiri sushi uses a small strip of toasted seaweed called nori to bind the whole mixture together, although this is not obligatory.
This vinegared rice, balled and pressed with two fingers forms the base of the nigiri. A slice of raw fish is then placed on the rice base, at times with a speck of wasabi. Nigirizushi is usually served in pairs. Sashimi is slices of fresh raw fish (sometimes, meat) presented with several types of garnishes.
