Overview
Dermoid cyst must be differentiated from teratoma, as well as other common benign tumors that develop in the head and neck, ovaries, or spine (such as pilar cysts, steatocystoma, pilomatrixoma, encephalocele, vascular malformations, lipoleiomyoma, pilonidal cyst, and lipoma).
Differential Diagnosis
Head and Neck
Dermoid cysts of head and neck must be differentiated from the following:[1][2]
- Pilar cysts (trichilemmal cyst)
- Acquired
- Intradermal
- Scalp is the most common site
- Steatocystoma multiplex
- Pilomatrixoma
- Encephalocele (when dermoid cysts appear on the medial aspect of the orbit)
- Ranula
- Vascular leiomyoma of the extracranial scalp
Ovarian Dermoid Cysts
- Ovarian dermoid cysts must be differentiated from the following:
- Haemorrhagic ovarian cyst
- Pedunculated lipoleiomyoma of the uterus
- Ovarian serous or mucinous cystadenoma/cystadenocarcinoma
Spinal Dermoid Cysts
- Spinal dermoid cysts must be differentiated from the following:[3]
- Lipoma
- Teratoma
- Spinal cord tumors (astrocytoma and ependymoma)
Others
Dermoid cysts must also be differentiated from the following:[4]
- Teratoma
- Pilonidal cyst
- Craniopharyngioma
- Metastases (cutaneous or lymph nodal lesions)
- Cutaneous ectopic brain
- Lymphatic malformation
