Oedema in the papillary dermis was evident occasionally in all clinical groups.

Three passes extended the damage into the papillary dermis.

Amyloid deposits were observed in the papillary dermis and were positive for the Congo red stain.

Moreover, risks may increase if tissue destruction extends to the papillary dermis or pilosebaceous units are ablated.

Two passes produced areas of denatured collagen with loss of viable cells in the superficial papillary dermis.

A scattered dot-like K14 staining is seen in papillary dermis, most prominently in cutaneous lupus erythematosus and lichen ruber.

Skin biopsy specimens from her buttock showed a sparse perivascular and interstitial infiltrate of neutrophils in the papillary dermis.

In addition, total cell number and the percentage of proliferating fibroblasts in the papillary dermis of UVB-irradiated mice were decreased.

In venous ulcers, the papillary dermis and the ulcer bed contained convoluted capillaries with phosphotungstic acid haematoxylin-positive pericapillary fibrin cuffs.

We observed elimination processes of damaged basal keratinocytes, which were probably produced by ultraviolet (UV) irradiation, into the papillary dermis.

Eight of the lesions were polypoid, based in the papillary dermis with extension to the superficial dermis and associated with an epithelial collarette.
