RESUMO
CASE REPORT: The case is presented of a 46-year-old male with right eye proptosis and conjunctival hyperaemia, of 18 months onset. A well-defined intraconal mass was found in the computed tomography. In magnetic resonance this was hypo-intense on T1, enhanced with gadolinium and hyperintense on T2. Excisional biopsy was performed, which was reported as a well-differentiated liposarcoma in the histopathology study. DISCUSSION: Liposarcoma is a malignant adipose tissue tumour. It is very rare in the orbit, with 5 histological types, the most common being myxoid. The treatment of choice is wide surgical excision and may be accompanied with radiotherapy. As it is an infiltrative tumour, It has a high rate of recurrence.

CASE REPORT: A 13-year-old boy presented with right eye proptosis and lateral dystopia. A soft non-pulsatile mass was found in the superomedial orbital region. An excisional biopsy was performed, for which the histopathology reported an epithelioid haemangioendothelioma. DISCUSSION: Haemangioendothelioma is a borderline vascular lesion within the spectrum of clinically benign and malignant tumours. These can arise from soft tissue or bone. There are few reports of these tumours located in the orbit.
