Multilocular epithelial cyst of spleen: A rare occurrence

Epithelial cyst of spleen presenting as hypersplenism

“…Some believe them to be congenital, formed by embryonic inclusions of epithelial cells from adjacent structures and consequent metaplasia, while others attribute their formation to developmental invagination of splenic capsular mesothelium and subsequent fluid accumulation. [1][2][3] Epithelial cysts are seen in 2nd or 3rd decade of life, as evident from our case. 1,2 Most are asymptomatic or minimally symptomatic, with dull pain and palpable mass in the left upper abdomen.…”

“…; and angiomatous cystsendothelium. 2 Except the last one that is referred to as lymphangioma or hemangioma, depending upon the fluid contained in the cyst, the others constitute epithelial cysts of spleen. 2 Pseudocysts are formed following trauma, abscess, necrotizing infection, or degeneration.…”

Splenic epithelial cyst mistaken with Hydatid cyst: A case report

“…SEC are congenital true splenic cyst characterized by an epithelial lining. They are divided in 3 subgroups depend on the type of epithelial lining, Epidermoid cysts are covered with stratified squamous epithelial lining, Mesothelial cyst with cuboidal epithelial lining and Dermoid cyst with squamous epithelium with hair follicles, sebaceous glands and skin appendages [ 8 ]. The epidermoid subtype represents 10% of all SEC and they are strongly linked to elevated CA 19-9 level because inner epithelial cells secrete CA 19-9 [ 9 ].…”

Why Total Splenectomy Is Better Choice Than Conservative Surgery in Splenic Cyst?

“…Primary cysts are thought to be congenital and attributed to misplaced epithelial tissue during embryogenesis with consequent metaplasia. William et al [5] suggested that these cysts are the result of invagination of splenic capsule mesothelium during development and fluid accumulation for unknown reasons.…”
