A healthy 18-year-old girl presented with a superotemporal epibulbar mass that was present since birth. Computed tomography revealed a cystic mass with fat-like low-density and a central oval-shaped mass that was isodense to the bone in the superotemporal region of the globe. Histopathology of the excised tumour revealed osseous choristoma and dermolipoma. Our review of literature yielded nine reported cases of epibulbar osseous choristoma within a dermolipoma and we reviewed these cases.

A 20-year-old woman presented with loss of vision in her right eye and a "black nose" after receiving hyaluronic acid filler injections in her right glabella 1 month prior. Her vision was no light perception, and external examination revealed resolving skin necrosis at the nasal tip. A dilated fundus exam showed a fibrotic membrane emanating from a pale optic nerve and a diffusely atrophic retina with sclerotic vessels. An MRI demonstrated scattered right-sided parietal lobe infarcts. These findings were consistent with inadvertent cannulation of the supraorbital artery, followed by injection of filler into the internal carotid circulation...

Merkel cell carcinoma (MCC) is one of the rarest eyelid tumors, with high mortality rate due to lymphatic and metastatic spread. We hereby report six cases of patients with histological diagnosis of MCC referred to our Orbit Unit between 2012 and 2018, focusing on diagnosis, treatment, and subsequent follow up. All patients underwent surgical excision and systemic work-up. Both MCC TNM and eyelid MCC TNM were used to stage lesions. MCC of the eyelid is usually misdiagnosed as benign or other malignant lesions...

Subperiosteal hematoma of the orbit is a rare complication that may occur in different situations. The most common cause is blunt trauma to the head region. The victims are usually young boys and the common site is usually orbital roof. There is no uniform approach in the literature in the management of subperiosteal hematoma. Conservative management has been recommended in cases with intact visual function. If conservative management is planned, complete resorption of hematoma may last several months, and the patients must tolerate diplopia and varying degrees of proptosis in this relatively long period of time...

Michelle M Maeng, Kyle J Godfrey, Michael Kazim
Dermoid cysts are histologically defined as surface epithelium encapsulating an inner lumen. They are well described in the literature as discrete, single masses, either circumscribed or dumbbell-shaped, with or without a longstanding fistula. Chronic granulomatous inflammation is often a feature of dermoid cysts, contributing to local soft tissue and bony destruction. Isolated multicystic dermoids are not well described. We present a case of a multilobular dermoid characterized both radiographically and histopathologically...
