Publication of my Handbook on Skin Ultrasound is Progressing, my new editor Jeny Ruelo has infused me new energy in this hard and long way of publishing.
With respect to hamartomas in some cases, there is difficulty in stablishing correct diagnosis from clinical point of view.
How can ultrasound help me in differentials with nevi (epidermal and sebaceous)?
A 45 year old phisician came to my office complaining of changes in congenital scalp lesion observed in the followin image
Differential diagnosis may include epidermal and sebaceous nevi
Ultrasound of this plaque is performed
Heteroechoic hypoechoic ill definned subepidermic area in scalp with minimal epidermal thickenning
Histologic diagnosis: Sebaceous nevus
We had anothe case of epidermal nevi that differed from this in ultrasound aspect
Homogeneous hypoechoic subepidermic area in scalp epidermal thickenning
Histologic diagnosis: Epidermal nevi
- Skin ultrasound can be applicated to scalp lesions
- As it can be observed ultrasound may be useful in the differential diagnosis of these two entities and of hep in presurgical planning.
