Acne

MESH Definitions

Chloracne

ACNE-like skin eruptions caused by exposure to CHLORINE-containing compounds. Exposure can be by inhalation, ingestion, or through the skin. Chloracne is often seen in people who have occupational contact with chlorinated pesticides, wood preservatives, and sealants.

Acquired Hyperostosis Syndrome

Syndrome consisting of synovitis, acne, palmoplantar pustulosis, hyperostosis, and osteitis (SAPHO). The most common site of the disease is the upper anterior chest wall, characterized by predominantly osteosclerotic lesions, hyperostosis, and arthritis of the adjacent joints. The association of sterile inflammatory bone lesions and neutrophilic skin eruptions is indicative of this syndrome.

Acneiform Eruptions

Visible efflorescent lesions of the skin caused by acne or resembling acne. (Dorland, 28th ed, p18, 575)
