Palatal cysts of the newborn

Palatal Cysts of the Newborn are a group of benign cysts that appear on the palate of a newborn baby. These cysts are typically small, ranging from 1 to 3 millimeters in diameter, and are often filled with a clear or yellowish fluid. They are usually discovered during a routine examination of the newborn's mouth, but they can also be detected during prenatal ultrasound imaging.

Etiology

Palatal cysts of the newborn are believed to be caused by the entrapment of epithelial remnants during the fusion of the palatal shelves. These remnants then proliferate and form cysts. The cysts are typically lined by stratified squamous epithelium, which is the same type of tissue that lines the mouth and throat.

Types

There are two main types of palatal cysts of the newborn: Epstein's pearls and Bohn's nodules.

• Epstein's pearls are found along the median palatal raphe and are caused by the entrapment of epithelial cells during the fusion of the palatal shelves. They are usually white or yellowish in color and are often mistaken for natal teeth.

• Bohn's nodules are found along the junction of the hard and soft palate and are believed to be remnants of salivary gland tissue. They are usually smaller than Epstein's pearls and are often mistaken for oral thrush.

Diagnosis

The diagnosis of palatal cysts of the newborn is usually made based on the clinical appearance of the cysts. They are typically small, round, and filled with a clear or yellowish fluid. They are usually discovered during a routine examination of the newborn's mouth, but they can also be detected during prenatal ultrasound imaging.

Treatment

No treatment is usually necessary for palatal cysts of the newborn, as they typically resolve on their own within the first few weeks of life. However, if the cysts are large or causing discomfort to the baby, they may be surgically removed.

Prognosis

The prognosis for palatal cysts of the newborn is excellent. These cysts are benign and do not pose any risk to the baby's health. They typically resolve on their own within the first few weeks of life, and do not cause any long-term complications.
