Is desmocollin 2 a new immunohistochemical marker indicative of squamous differentiation in urothelial carcinoma?
DSC2 staining offers high sensitivity (96%) and high specificity (100%) for the detection of squamous differentiation in UC. DSC2 is a useful immunohistochemical marker for separation of UC with squamous differentiation from pure UC.
Tenosynovitis and especially isolated tenosynovitis are frequently detected by US in symptomatic ankles of early RA patients. US examination of ankles in early RA patients should include scans of the medial and lateral recess to enable early detection of ankle tenosynovitis.
