Overview
The majority of patients with dermoid cysts are asymptomatic. If left untreated, dermoid cysts gradually increase in size and produce symptoms depending upon their anatomical location. Common complications of ovarian dermoid cysts include torsion, rupture, and infection.[1][2] Common complications of periorbital dermoid cysts include inflammation and recurrence when not completely excised.[1] Rupture is the most common complication of spinal dermoid cysts.[1] Common complications of intracranial dermoid cysts include compression of adjacent structures from the mass effect and rupture of the cysts.[3][4] Infection is the most common complication of dermoid cysts of the floor of the mouth.[5] Malignant transformation usually into squamous cell carcinoma is a rare complication of dermoid cysts.[6][2] Depending on the anatomical location of the tumor, the prognosis may vary.
Natural History
The majority of patients with dermoid cysts are asymptomatic. If left untreated, dermoid cysts gradually increase in size and produce symptoms depending upon their anatomical location.[1]
Complications
- Malignant transformation usually into squamous cell carcinoma is a rare complication of dermoid cysts.[6][2]
Ovarian Dermoid Cyst
- Common complications of ovarian dermoid cysts include:[1][2]
- Torsion
- Rupture
- Infection
- Malignant transformation, usually into squamous cell carcinoma (adults) or rarely into endodermal sinus tumours (children)
Periorbital Dermoid Cyst
- Common complications of periorbital dermoid cysts include:[1]
- Inflammation
- When a dermoid cyst is disrupted, it results in an inflammatory reaction.
- Recurrence when not completely excised
- Inflammation
Spinal Dermoid Cyst
- Rupture is the most common complication of spinal dermoid cysts.[1]
- Rupture of the cyst may result in the dissemination of fat droplets into the subarachnoidal and ventricular spaces which may lead to ventriculitis, arachnoiditis, and eventually mental disorders and coma.[7]
Intracranial Dermoid Cyst
- Common complications of intracranial dermoid cysts include:[3][4]
- Mass effect
- Compression of adjacent structures, e.g. optic chiasm
- Rupture (spontaneous, traumatic, or iatrogenic (at resection))
- Fat droplets from the ruptured cysts may disseminate into the subarachnoid space and ventricles which may result in the development of aseptic chemical meningitis
- Mass effect
Dermoid Cysts of the Floor of the Mouth
- Infection is the most common complication of dermoid cysts of the floor of the mouth.[5]
Prognosis
- Depending on the anatomical location of the tumor, the prognosis may vary.
- Although benign and slow growing, spinal, ovarian, and intracranial dermoid cysts carry a risk of rupture spontaneously, during surgery or after a traumatic event which is associated with a high morbidity and mortality.[8]
- In patients with malignant transformation, prognosis depends on the stage of the disease.[6]
