Pathology of Dermoid Cyst of the Pancreas

Dr Sampurna Roy MD             

 

Dermoid cyst, also called cystic teratoma of the pancreas is a benign, well-differentiated, extremely rare germ cell neoplasm.

Dermoid cyst of the pancreas is a true cyst and consists of stratified squamous epithelium and underlying connective tissue.

Clinical presentation: It is non specific and include abdominal pain, back pain, nausea, vomiting, anorexia, weight loss, fatigue and fever.

Gross features:  Cyst contains differentiated tissues from one or more germ cell layers, usually ectodermal.

The cyst content appears  "cheesy"  or "caseous", with keratinaceous and sebaceous secretions.

Rarely the  cyst content may be clear and serous.

Microscopic features: The cyst is lined by stratified squamous epithelium.

 

Mucinous epithelium, respiratory-type mucosa, sebaceous units and hair follicles are readily identifiable in dermoid cysts.

The serum markers, such as CEA and CA19-9, are usually significantly lower in dermoid cysts rather than in other  pancreatic cystic neoplasms.

Differential diagnosis : Pancreatic cysts lined by squamous epithelium, e.g. lymphoepithelial cyst  and epidermoid cyst.
