Epidermoid Cyst vs. Hemangioma
Left picture: In this case the diagnosis is an epidermoid cyst with former rupture, correspoding to the operative and histological findings with giant cells and fibrosis of the surrounding skin and subcutis. A spontaneous recovery would not have been possible. Right picture: The cause of the mass is a rapidly growing hemangioma of the skin with a large subcutaneous component. Surgery was performed because of the danger of hemorrhage, rapid increase in size, and an unlikely recovery within a short period.
Two infants with a large tumor in the midline of the head. Left picture: In this 8-month-old infant there has been a mass since birth. According to the mother, the mass has slowly decreased in size since that time. Right picture: In this young infant the mass over the vertex has distictly grown during the first month of life. Left picture: The mass which lies just behind the closed posterior fontanel, is covered with normal skin, is tight, and not relocatable on its base. The MRI shows no intracranial connection. Right picture: This mass is increasing in size on crying, and is covered on its top by a clear-red structure which reminds of granulation tissue.
