    Optic neuropathy in Behçet's disease. Report of two cases (1999)

    Notes: Abstract Orbital magnetic resonance imaging demonstrated increased signal of the optic nerve in short time inversion recovery (STIR) images of two young women with unilateral visual blurring. In both, recurrent oral and genital ulcerations and papulopustular lesions appeared within the next 14–15 months, respectively, allowing a diagnosis of Behçet's disease. Optic neuropathy may be an early manifestation of Behçt's disease and clinical follow-up is crucial for its diagnosis.

    Notes: Abstract  Orbital cavernous hemangiomas (OCH) have thick and highly cellular vascular walls. Ultrastructural studies have demonstrated the smooth muscle nature of these cells. Vascular neoplasms can modify their morphological and clinical features under hormonal stimulation. The purpose of the present study was to investigate the presence of smooth muscle markers and sex steroid receptors in 12 cases of OCH. Orbital cases were compared with cutaneous hemangiomas and subcutaneous angioleiomyomas. Smooth muscle actin (SMA) and desmin were localized in spindle cells of the vascular walls of all 12 cases studied. OCH showed immunohistochemical positivity with progesterone receptor (PR) antibody both in smooth muscular and in endothelial cells. For comparison, sex steroid receptors were studied in 10 cases of cutaneous cavernous hemangioma and in 10 cases of subcutaneous angioleiomyoma. PR was found in smooth muscle and endothelial cells of 6 out of 10 cases of subcutaneous angioleiomyoma and in none of the cases of cutaneous cavernous hemangioma. No positivity was obtained with estrogen receptor (ER) antibody in any of the cases tested. The present data suggest that OCH share morphological and immunohistochemical features with subcutaneous angioleiomyomas. Furthermore, immunohistochemical positivity with PR antibody indicates that OCH have to be added to the list of mesenchymal lesions that express sex steroid receptors.

    Gaze-evoked amaurosis heralding orbital angiomyoma. Case report (1997)

    Description / Table of Contents: Sommario È descritto il caso atipico di una paziente che presentò un'amaurosi da sguardo come segno isolato precoce di un angiomioma orbitario. La tomografia computerizzata o la risonanza magnetica devono essere rapidamente eseguite in pazienti con amaurosi da sguardo in modo da identificare o escludere un possibile sottostante tumore orbitario.
    Notes: Abstract The unusual case of a patient presenting with gaze-evoked amaurosis as an early and isolated sign of orbital angiomyoma is reported. Computed tomography or magnetic resonance of the orbits need to be expeditiously performed in patients with gaze-evoked amaurosis in order to identify or rule out the possible presence of an underlying tumor.
