Histology of trichoepithelioma
Scanning power view reveals a tumour comprised of multiple nodules situated within the dermis (Figure 1). Small horn cysts, abortive hair follicles and calcification are frequently seen (Figure 2). The stroma is denser and more cellular than with basal cell carcinoma, and there is often focal stromal cracking (Figure 2, arrow). Often pronounced bulbar differentiation may be seen, emulating the follicular bulb and papilla; these structures have been referred to as papillary mesenchymal bodies. (Figure 3, arrow).
