    ABSTRACT: Retiform hemangioendothelioma is a rare intermediate or borderline neoplasm of the blood vessels that mostly occurs in extremities. Here we report a unique case of retiform hemangioendothelioma presented in the external auditory canal. 58-year-old male patient presented with the complaint of right ear swelling for 4 years. On examination, a spherical swelling in the right ear was found occluding the view of external auditory canal. The tumor was removed surgically. Intraoperatively, the mass was found attached to the outer part of the right external auditory canal near the root of helix. Histopathology of the resected tumor showed typical features of retiform hemangioendothelioma. In addition, immunohistochemical analysis revealed that tumor was positive for endothelial cell marker CD34 and occasionally positive for cell proliferative marker Ki-67.

    • "Retiform hemangioendothelioma (RH) is a very rare vascular lesion that was first described by Calonje et al., in 1994.[1] Despite being mostly reported as an acquired skin lesion that affects young and middle-aged adults, it may also develop as a congenital vascular lesion.[2] RH shows limb predilection, but is occasionally reported in the trunk, penis, or scalp.[3] Although it frequently recurs, distant metastases are exceedingly rare.[4] "

    ABSTRACT: Retiform hemangioendothelioma (RH) is a distinct entity in the spectrum of vascular tumors with a high local recurrence rate. It is considered a low-grade, well-differentiated cutaneous angiosarcoma with low metastatic potential. We report here for the first time a case of medial canthus recurrent RH. It may be helpful in our practice to include RH as a differential diagnosis of eyelid lesions. It is noteworthy that the progressive course and recurrence tendency of RH might be misdiagnosed as angiosarcoma or basal cell carcinoma (BCC), if not expected and carefully evaluated by the pathologist.

    ABSTRACT: Retiform hemangioendothelioma is a rare, intermediate-grade, locally aggressive vascular tumour that involves the skin and soft tissues of the trunk and extremities (1-10). Macroscopically it appears as a plaque or an exophytic lesion. Involvement of the hand or upper extremity is rare, with only Three cases reported in the literature (2, 3, 9). Treatment usually involves surgical excision or amputation (2). We present the case of a middle-aged woman with a retiform hemangioendothelioma of the small finger, successfully treated with surgical excision with no signs of recurrence at 4 years of follow-up.
