This report describes a case of mucinous carcinoma and Müllerian metaplasia arising within an appendiceal duplication cyst found incidentally during an emergency Caesarian section. Intestinal duplication cysts are rare and although there are occasional reports of malignant transformation, this is the first case where Müllerian metaplasia was found concurrently with a malignancy. There was no pr...

In this paper, we define duplication corona, duplication neighborhood corona and duplication edge corona of two graphs. We compute their adjacency spectrum, Laplacian spectrum and signless Laplacian. As an application, our results enable us to construct infinitely many pairs of cospectral graphs and also integral graphs.

Congenital anomalies and variations should be kept in mind when evaluating diseases the pediatric patient group. A 12 years old girl presented with findings of acut abdomen. Clinical laboratory data were consistent acute pancreatitis. Imaging showed a peristaltic cystic tissue thick wall central lumen head pancreas.
