Mönckeberg medial calcific sclerosis - An interesting finding!!

• First described by Johann Georg Monckeberg.
• It occurs most often in patients >50 years of age.
• Calcium deposits are seen in the muscular wall (media) of blood vessels.

• Results in thickening of the arterial wall and loss of elasticity.
• Does not have any serious pathologic consequence, since the lumen is patent.

In figure, arrow points to purple fragmented deposits that represent calcium.

The special stain that would highlight calcium is Von Kossa (stains the deposits black).
