Concentric rings within a breast mass on sonography: Lamellated
keratin in an epidermal inclusion cyst.
The most useful radiographic-finding that suggests Meckel's diverticulum as the cause of obstruction is lamellated
calcification in the right lower quadrant.
Such glomeruli usually have wrinkled, frequently lamellated, Bowman capsule basement membrane (Figure 1, B).
The interstitial-type collagen may be present outside the Bowman capsular basement membrane, between layers of the lamellated basement membrane, or even inside the Bowman capsular basement membrane (Figure 2, A through C).
The osseous choristomas belong to the last category where in these contain only mature lamellated bone.
Microscopically, the H&E stained sections of the decalcified nodule was composed of mature lamellated bone and fibrous connective tissue capsule on outer aspect.
Other frequent findings in sarcoidosis are concentric, lamellated
fibrosis around granulomas (Figure 5, B), hyalinization of and within granulomas, granulomatous vasculitis,36,98 absence of granulomas within air spaces, absence of organizing pneumonia, and absence of interstitial inflammation away from the granulomas.
Calcifications in meningioma are smaller, round, and lamellated
in contrast to the large, irregular calcifications of CPN.
These acellular nodules may reveal layering or a lamellated
An elastin stain of the papillae demonstrated a central, loosely lamellated
elastic tissue core with tapering rudimentary elastin fibers located toward the periphery (Figure 3).
Its microscopic characteristics are of a thick, green to gray, lamellated
aggregate of dense inflammatory cells, mostly eosinophils and some neutrophils, in a background of tenacious-appearing gray mucus, serum, and Charcot crystals.
