Bilateral primary squamous cell carcinoma of the conjunctiva
Squamous cell carcinomas (SCCs) of the conjunctiva are rare, with an estimated incidence of 1–2.8 per 100 000 people per year.1 SCC is the most frequently occurring malignant epithelial tumour of the conjunctiva.2 Here we present a case of a patient presenting with 2 distinct primary carcinomas of the conjunctivae over a 3-year period.Conjunctival Kaposi’s sarcoma with orbital extension in an HIV-negative man
Kaposi’s sarcoma (KS) is a vascular tumour whose development requires infection by human herpesvirus 8 (HHV-8). Although most commonly found in immunosuppressed patients, such as those AIDS, in the United States, classic KS is often found in older-aged men of European or Mediterranean ancestry without immunosuppression. Involvement of the skin of one’s extremities in classic KS is typically more common than that of viscera or mucocutaneous surfaces.Acute visual loss secondary to ruptured sinus mucoceles
Mucoceles are slow-growing epithelial-lined cystic lesions of the paranasal sinus. They result from obstruction of the sinus ostium by chronic inflammation, prior surgery, trauma, or tumour.1–3,5 These mucus-filled cysts can expand, erode through bone, and extend into the orbit or cranium.4 Patients with a significant mass extending into the orbit usually undergo surgical excision on an elective basis. We present 2 cases of rapidly progressing visual loss caused by orbital mucoceles that required emergent treatment.
