Collagenosis, reactive perforating. 12 monthsago for the first time appeared itchy papules of different size with central depression and hyperkeratotic plug.

Collagenosis, reactive perforating papules: Itchy red papules of varying size, first appearing about 12 months ago, with a central depression and hyperkeratotic clot; central crust formation is already detectable in early inflammatory papules.

Collagenosis, reactive perforating: for 1 year continuous new formations of 0.1-0.5 cm large, slightly itchy, coarse, red, rough papules, which disintegrate centrally during growth and are covered with an adherent crust.

Collagenosis, reactive perforating p apules: first appeared about 8 months ago, itchy papules with central depression and hyperkeratotic clot, no known underlying disease.

Collagenosis, reactive perforating: dense, disseminated distribution of lesions, some of which are linearly arranged (Koebner phenomenon).

Collagenosis, reactive perforating. detail enlargement: solitary, 0.3-1.3 cm large, red papules with a coarse central horn plug. the smaller papules correspond to an early stage of the disease.

Collagenosis, reactive perforating. detail enlargement: 0.5-1.5 cm large, indurated, livid papules and plaques on the upper back, partly with hyperkeratotic plug, partly confluent.

Collagenosis, reactive perforating. detail section: homogenized collagen bundles reaching into the ulcer base and surrounded by an inflammatory infiltrate (in the figure above centered). the surface epithelium is already destroyed.

Collagenosis, reactive perforating. fresh, centrally ulcerated nodule with fresh granulation tissue and discharge of collagenous fiber bundles (collagenous material stained red; EvG staining) The surrounding epithelium is largely unchanged.
