3. Fig MA 4-1 Infiltrating ductal carcinoma. Focal skin thickening (arrow) on the lower aspect of the breast. Beneath the thickening is a 1-cm spiculated mass that is tethering the skin. 2

4. Fig MA 4-2 Inflammatory carcinoma. There is strikingly increased density of the left breast relative to the right and diffuse thickening of the skin. A large, rounded mass is noted in the upper outer quadrant. 2

5. Fig MA 4-3 Metastatic melanoma. Marked skin thickening (arrow) is associated with a diffuse increase in the density of the interstitium. 2

6. Fig MA 4-4 Radiation therapy. (A) Initial mammogram after lumpectomy and radiation therapy for a carcinoma in the lower inner quadrant of the breast. (B) Three years later, an oblique view shows marked skin thickening with diffusely increased density of the breast near the chest wall. 2

7. Fig MA 4-5 Mastitis with breast abscess. Prominent skin thickening over the areola (arrow) and diffuse skin thickening elsewhere. Generalized increased density in the area of the subareolar lactiferous ducts. 2

8. Fig MA 4-6 Fat necrosis. Mammogram obtained 6 months after severe blunt trauma to the breast shows skin thickening and retraction inferiorly (arrow) associated with multiple lucent masses with rim-like calcifications, typical of fat necrosis and oil cysts. 2

9. Fig MA 4-7 Chronic graft-versus-host disease. Craniocaudal mammograms of the right (A) and left (B) breasts show marked bilateral skin thickening. The periareolar skin of the right breast exceeds 1 cm in thickness. A screening mammogram obtained 3 years earlier showed no skin thickening. 6
