Background Subcutaneous vaccination or desensitization may induce persistent nodules at the injection sites. Without knowledge of prior injection, histopathological work-up be challenging. Objective Aim this study was to contribute unclear subcutaneous nodules, especially their differentiation from cutaneous lymphoma. Methods We retrospectively reviewed clinical data and slides four patients wi...

Chromosomal translocations that juxtapose antigen receptor genes and oncogenes are frequently associated with lymphoid malignancies. In this issue, Robbiani et al. (2008) show that activation-induced deaminase (AID), an enzyme involved in antigen receptor gene diversification, generates DNA double-strand breaks (DSBs) in oncogenes, and Tsai et al. (2008) propose that AID and the recombinase-act...

Black amorphous carbon particles (carbon black), white titanium dioxide, azo or polycyclic pigments create all varieties color shades in visible spectrum.

PULMONARY PSEUDOLYMPHOMA 691 percutaneous or bronchoscopic aspiration, avoiding contammation by bacteria in the upper airway. Enterococci have been implicated primarily in the genitourinary, endocardial, and abdominal infections. Few reports have considered them as a cause of a bacterial pneumonia or lung abscess. Rantz and Kirby,3 in a review of streptococcal infections, reported none. Duma et...
