Myxoid change within cellular blue naevi: a diagnostic pitfall

Histopathology. 1992 Jun;20(6):527-30. doi: 10.1111/j.1365-2559.1992.tb01039.x.


We describe four cases of a distinctive myxoid change located in the centre of cellular blue naevi. Because all the reported lesions were large and were present on pressure-exposed locations, the myxoid change is thought to be caused by pressure together with direct repeated minor tissue trauma.
