Example text

8)5. 9)7–9,13.  Melanosis differs from fibrosis by the additional presence of a band of melanophages in a thickened papillary dermis9,13. 11).  Other vascular dermoscopic structures include telangiectasia which represent dilated vessels in the papillary dermis and red­blue areas (lacunae) which correspond to dilated vascular spaces in the dermis.  Sometimes milia­like cysts are pigmented, and thus can resemble globules (see Chapter 6b).  Histopathologically, comedo­like structures correspond to the concave, often hyperkeratinized clefts, of the epidermis (see Chapter 6b).

Histopathologically, they represent nests of pigmented epithelial nodules of basal cell carcinoma (see Chapter 6a).  Histopathologically, they correspond to the nests of basal cell carcinoma radiating from a follicular epithelium (see Chapter 6a).  When a network is absent, ovoid nests are highly suggestive of basal cell carcinoma (see Chapter 6a).  They have to be differentiated from multiple blue­gray dots (which correspond to melanophages and melanin dust; see Chapter 6a).  Superficial black network: an additional dermoscopic clue for the diagnosis of pigmented spindle and/or epithelioid cell nevus.

Dermoscopy should not be regarded as simply a magical tool for facilitating the diagnosis of pigmented skin lesions, but it should also be considered as a useful tool for evaluating in vivo gross pathology.  Therefore, combining dermoscopy more closely and frequently with the cutaneous pathology will be of substantial help in refining the definitions and diagnostic criteria of pigmented skin lesions for both dermatologists and dermatopathologists.  Narrow width in dermal papillae results in a narrow pigment network.
