description: The dataset includes the following content:Patient's skin lesion photos, pathological tissue examination photos, and strain morphology photos. Figure 1 shows the clinical presentation of the patient. a-h Erythema accompanied by scales covered the patient’s body, and multiple disseminated, firm and dusky red to purple nodules and plaques were distributed over his trunk (a, b), arms (c, d , g) and lower extremities (e, f), presenting with crusts and erosions. (h) All toenails were thickened, dystrophic and showed yellowish discoloration. Figure 2 provides histological descriptions of the erythema and nodules.Histological description of the erythema and nodules. a, b Histological examination of the erythema revealed epidermal hyperplasia and hypertrophy, infectious granuloma in the dermis, and dense inflammatory infiltrate consisting of epithelioid cells, lymphocytes, plasma cells, neutrophils, and scattered multinucleated giant cells. Hematoxylin and eosin (HE) ×100 (a), HE ×200 (b). c, d Histopathology of the nodules revealed pseudoepitheliomatous epidermal hyperplasia, inflammatory granulomatous infiltration, and dense inflammatory infiltration in the dermis, with infiltrating cells identical to those of the erythema.
