- Primary salivary duct carcinoma (SDC) of the parotid gland is a relatively uncommon tumour. Amongst the noted cases in the literature, metastasis of the primary SDC is known to involve the lungs, liver, bones, lymph nodes, gingiva, vagina, and rarely the orbit.1–4 The reported cases of orbital metastasis from a primary SDC have shown a good prognosis, whenever appropriate intervention was instituted at the earliest. In this report, we describe the clinical difficulties, investigations, and management of a metastatic SDC of the orbit that presented prior to manifestations at the primary location.
- Histoplasmosis is a granulomatous infection caused by the dimorphic fungus Histoplasma capsulatum. It has two variants which are known to cause human infection: Histoplasma capsulatum var capsulatum and Histoplasma capsulatum var duboisii. Ocular manifestations are known in the form of involvement of the choroid and retina.1 Here, we describe the clinical features, diagnosis, and management of an isolated conjunctival histoplasmosis infection as a primary manifestation in an immunocompromised individual.
- Angiomyxomas are benign mesenchymal tumours that rarely involve periocular structures. The age at which patients present with them ranges from 4 to 60 years.1,2 These tumours commonly involve the pelvic area in females. Only a few cases of conjunctival and orbital angiomyxoma have been described in the literature.1–4 When they involve the periocular structure, they need special attention both during and after surgery. Here we describe the clinical features, diagnosis, and management in a case of conjunctival angiomyxoma.
- Pleomorphic adenoma is the most common benign epithelial tumour of the lacrimal gland. It is composed of both epithelial and mesenchymal elements; the latter mainly consists of myxoid stroma. Typically, on imaging, it presents as a well-defined, solid mass in lacrimal gland fossa with bony remodeling. Internal architecture of the tumour may be heterogeneous as the myxoid stroma within the tumour can be seen as hypodense areas. Presence of cystic spaces within pleomorphic adenoma of the lacrimal gland is extremely rare and can lead to misdiagnosis.
