F1Ch7 (106049): The level is approximately the mid-portion of the dermis. A vessel and its laminated adventitia runs diagonally across the field from right to left. Collagen bundles above are mostly cut in cross-section and somewhat hypereosinophilic. The domain above the vascular partition is the abnormal fibrous matrix of the reticular dermis as seen in some fibrous papules. Below the vascular partition, the collagen bundles are rather thin; they are loosely spaced in a clear matrix. Fibroblasts are hypertrophied; they have lavender cytoplasm. This partitioning of patterns is common in examples of fibrous papule. To the right, a vessel, cut in cross-section, is outlined by loosely spaced, brightly acidophilic lamellae. These lamellae are interpreted as reduplicated basement membranes.
