A rare common cystic lymphatic malformation characterized by a benign cystic lesion composed of dilated lymphatic channels. Mixed cystic lesions consist of cysts both larger (macrocystic) and smaller (microcystic) than 1 cm in diameter. They usually present at birth or during the first years of life and most often occur in the head and neck region but may affect any site. Symptoms depend on the location and extent of the lesion. Infection, trauma, or intracystic hemorrhage can lead to lesional expansion. Malignant transformation does not occur.	Associated morphology	True	Cystic dilatation	Inferred relationship	Some	1
A rare genetic hepatic disease characterized by multiple segmental cystic dilatations of both central and smaller peripheral bile ducts associated with congenital hepatic fibrosis. Age of symptom onset is variable, as is disease progression. Patients present recurrent cholangitis, hepatolithiasis, and cholecystolithiasis. Portal hypertension may appear later in the disease course, and the risk of developing cholangiocarcinoma is increased significantly. The syndrome is often associated with autosomal recessive polycystic kidney disease.	Associated morphology	True	Cystic dilatation	Inferred relationship	Some	2
