RESUMO
We herein report the histopathology of a rare case of an idiopathic internal mammary artery aneurysm in a 61-year-old asymptomatic woman. Chest radiography during an annual medical check-up incidentally revealed the aneurysm, which was initially mistaken for a mediastinal tumor. Given that a rupture of the aneurysm could have been life-threatening, it was removed surgically, and found to possess a paper-thin arterial wall with cystic medial degeneration.

The stereoselective total synthesis of atpenins A4 (2) and B (3), harzianopyridone (4), and NBRI23477 B (5) have been developed using a convergent approach involving the coupling reaction of a common iodopyridine with an aldehyde corresponding to the appropriate side chain of the desired compound. Furthermore, the absolute configurations of atpenin B (3), harzianopyridone (4), and NBRI23477 B (5) have been unambiguously determined.

We report three elderly men with high serum IgG4 concentrations and multiple lymphoplasmacytic inflammation of the salivary glands, lymph nodes, pancreas, and renal interstitium. The infiltrating plasma cells had strong immunoreactivity for IgG4, even in patients without pancreatic lesions. These cases show that IgG4 is associated not only with autoimmune pancreatitis, but also with other systemic lymphoplasmacytic disease.
