Haemangioendothelioma on the conjunctiva of the upper eyelid.

A 62-year-old man visited the authors' clinic complaining of a mass on the palpebral conjunctiva of the right upper eyelid. The 2.0 cm x 1.2 cm sized, red and painless mass underwent incision and biopsy for histopathological examination. The mass was confirmed to be Kaposiform haemangioendothelioma characterized by densely packed spindle cells. These cells were positive to vimentin, CD31 and factor VIII-related antigen by immunohistochemical stain. The mass was completely resolved by oral steroid therapy and has not recurred through the presentation. Kaposiform haemangioendothelioma generally occurs in infant and adolescent periods and is characterized by rapid progression and invasion to adjacent tissue. Herein, an unusual case of Kaposiform haemangioendothelioma affecting the conjunctiva of the upper eyelid on a middle-aged man is reported.
