Abstract:
Trichoblastoma is a benign cutaneous neoplasm that is clinically and histologically similar to basal cell carcinoma. We report the dermoscopic features seen in 2 cases of facial trichoblastoma. One case presented with very short, delicate, scarcely branching telangiectases against a pearly white background. In the second case, the veins were also short and scarcely branching, but they were arranged in a crown pattern, with white striae and milia-like cysts. Although dermoscopic evidence of fine, scarcely branching telangiectases is not specific to a diagnosis of trichoblastoma, these features may be useful for differentiating this neoplasm from nodular basal cell carcinoma.

01:11Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
