Urticarial vasculitis is characterized clinically by urticarial skin lesions and histologically by leukocytoclastic vasculitis. Hypocomplementemic urticarial vasculitis is associated with connective tissue diseases such as systemic lupus erythematosus (SLE). We report a case of urticarial vasculitis that preceded manifestations of SLE.

The IF of gallbladder cancer is characterised by significantly increased expression of p21, p53 and strong COX2 expression, and strong cytoplasmic COX2 expression at IF is associated with a poorer prognosis. Heterogeneity between TC and IF should be considered in in situ molecular studies, especially during interpretation of immunohistochemical stain results and tissue microarray construction.

Our findings indicate that CXCL12 might serve as an effective novel supplementary diagnostic marker for PTC.

Extramedullary plasmacytoma involves organs outside the bone marrow; however, involvement of the pancreas is rare. We recently experienced a case of extramedullary plasmacytoma of the pancreas that was diagnosed by endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA). EUS-FNA, which has a high diagnostic accuracy and an excellent safety profile, is the modality of choice for establishing tissue diagnosis. We report a case of extramedullary plasmacytoma of the pancreas diagnosed using EUS-FNA.
