An eight-year-old Japanese @entity1 developed @entity490 , followed by @entity410 and @entity909 . He was taken to an emergency room but could not be resuscitated. At autopsy, the left main coronary trunk (LMT) demonstrated an increase in caliber with severe luminal narrowing, and the @entity714 ( @entity714 ) subsequent to the LMT showed severe @entity850 . Microscopically, the intima of the LMT demonstrated severe @entity82 and infiltration of lymphocytes and histiocytes suggesting @entity1333 , and the small lumen was occupied by a fresh @entity715 . The @entity714 showed significant intimal thickening with strong lymphocytic inflammation at the edge of the thickening. The left ventricle showed widespread @entity583 in the recovery stage. There were no findings of @entity731 , @entity1333 or fibrocellular changes in the ascending aorta or intravisceral arteries other than the LMT and the @entity714 under investigation. The increase in the caliber of the LMT and the limitation of @entity3468 to the LMT and the subsequent branch suggested @entity573 ( @entity573 ), but it was atypical that the @entity1 had no clinical history consistent with @entity573 . The present case showed no findings suggesting classical @entity11657 (cPAN) at the acute or scar stage in the other vessels being investigated, and cPAN in childhood is rare compared to @entity573 . A nonspecific inflammatory reaction (single organ @entity1333 , SOV) was also considered as a possible cause, but it is difficult to determine whether the cause of the @entity3979 in the present case was SOV because the sampling of arteries was insufficient. If forensic pathologists make unusual findings suggesting @entity1333 at autopsy, the collection of a sufficient number of vessels of various sizes is warranted.

Sudden death of a @entity1 from XXXX due to @entity3468 of the left coronary trunk.
