Rosacea papulo-pustulosa: persistent, intermittent plaque-like inflammation of the nose, with recurrent, painful intralesional pustular lesions DD: large-boned sarcoidosis (type lupus pernio).
Note: the recurrent occurrence of pustules in the lesion (see here nasal bridge) speaks against the diagnosis "sarcoidosis"!

Basal cell carcinoma sclerodermiformes C44.L

Basal cell carcinoma (overview) C44.-
Nodular or nodular basal cell carcinoma: Relatively inconspicuous, non-symptomatic, red nodule with a smooth surface (see incident light image as inlet); the bizarre (tumor) vessels of the basal cell carcinoma become visible in incident light.

Basal cell carcinoma nodular C44.L
Basal cell carcinoma, nodular. solitary, 1.0 x 1.2 cm large, broad-based, firm, painless nodule, with a shiny, smooth parchment-like surface covered by ectatic, bizarre vessels. Note: There is no follicular structure on the surface of the nodule (compare surrounding skin of the bridge of the nose with the protruding follicles).
