Low-power view; for high-power view, see File:Moderately dense infiltrate of plasma cells and lymphocytes in the papillary dermis.

From original CC-BY report: "Histopathologic findings of yaws papilloma A skin punch biopsy of the papilloma on the left axilla of the index case (Case 1) was performed by the principal investigator in the Rural Health Center 2 weeks post-treatment. The specimen was processed in the Philippine General Hospital and read by a dermatopathologist of the Division of Dermatology. The biopsy showed psoriasiform epidermal hyperplasia and band-like lymphocytic infiltrates in the papillary dermis, with thickening of the basement membrane. There were moderately dense infiltrates of plasma cells and lymphocytes in the papillary dermis. The histopathologic diagnosis was lichenoid psoriasiform dermatitis with plasma cells. These findings were consistent with yaws " |
