Mucosa-associated lymphoid tissue [MALT] lymphoma of the ocular adnexae is rare. A 39-year-old woman presenting with proptosis was diagnosed to have non-Hodgkin's lymphoma with intermediate-sized cells and lymphoepithelial lesion. Unlike most MALT lymphomas, this lymphoma was found to be CD5-positive. Small lymphocytic lymphoma/chronic lymphocytic leukemia and lymphoplasmacytic lymphoma are two other entities that are CDS-positive and have a morphological pattern similar to MALT lymphoma. The case report and approach to the diagnosis is discussed

Oncocytoma of the lacrimal sac is a rarely encountered clinical entity. We report the case of a 72-year-old female patient who was diagnosed to have bilateral nasolacrimal duct obstruction during a pre-cataract surgery screening. Subsequently, she underwent bilateral dacryocystectomy. Histopathological examination of the left lacrimal sac revealed a tumour composed of acini lined by oncocytic cells; features consistent with those of a lacrimal sac oncocytoma. Although rare, oncocytomas arising from the lacrimal sac may co-exist with a nasolacrimal duct obstruction. This report describes the histological and immunochemistry characteristics of oncocytomas and underscores the need to subject all excised lacrimal sacs to histopathological examination

Sebaceous gland carcinoma [SGC] is a rare tumour occurring at periocular and extra-ocular sites. SGC can be a challenging diagnosis for both clinicians and pathologists. High recurrence rates and a tendency for intra-epithelial spread, locoregional and distant metastases make it important for SGC to be suspected and be included in the differential diagnosis of an eyelid lesion. Early diagnosis, that may sometimes need ancillary testing, and prompt management using a multimodal approach can help reduce morbidity and mortality in patients with SGC
