Kaposi's sarcoma (KS) is a malignant vascular tumor, caused by the human herpesvirus 8. It is one of the commonest tumors in human immunodeficiency virus (HIV) patients and not uncommonly the first manifestation of acquired immunodeficiency syndrome (AIDS). Case. We present a case of an isolated bulbar conjunctival KS on a 43-year-old HIV positive male, with no other lesions. Excision and cryot...

Conjunctival tumors are one of the most frequent of the eye and adnexa. They comprise a large variety of conditions, from benign lesions such as nevus or papilloma, to malignant lesions such as epidermoid carcinoma or melanoma which may threaten visual function and the life of the patient. They can arise from any cellular component, but the most frequent are of epithelial and melanocytic origin...

Keratoacanthomas rarely occur in the conjunctiva. We report a case of a 24-year-old man with a rapidly growing conjunctival mass. The tumor was excised with a safety margin to exclude squamous cell carcinoma and was histopathologically diagnosed as a keratoacanthoma. There has been no recurrence over 2 years of follow-up. To the best of our knowledge, he is the youngest patient to be diagnosed ...

CASE REPORT Pigmented conjunctival lesions are a diagnostic challenge for the clinician. A 37-year-old man presented with a pigmented mass involving the conjunctiva of his right eye. Clinically, a diagnosis of malignant melanoma was made and a wide excision of the tumor was performed. The histopathologic diagnosis was seborrheic keratosis. DISCUSSION Seborrheic keratosis is a benign lesion wh...

BACKGROUND This study was conducted to detect microbial pathogens in conjunctival mucosa-associated lymphoid tissue (MALT) lymphoma specimens in an attempt to determine possible associations between conjunctival MALT lymphoma and microbial infections. MATERIAL/METHODS Using PCR technique, freshly obtained tumor specimens from 16 cases of conjunctival MALT lymphoma, as confirmed by postoperati...

We report the case of 55 years old woman who present a conjunctival growth in the right eye (Figure A). The biopsy showed a conjunctival epidermoid carcinoma in situ. Conjunctival epidermoid carcinoma is a rare tumor, it is more common in male and elderly patients, but may occur earlier in patients with xeroderma pigmentosa or AIDS. The major risk factor for the disease is the exposure to ultra...

PURPOSE Dry eye condition is an extrahepatic manifestation associated with chronic hepatitis C virus (HCV) infection. Since conjunctival inflammation can contribute to the dry eye condition, in the present study we analyzed the conjunctival inflammatory response to HCV core and NS3 proteins. METHODS We used primary human conjunctival fibroblasts for our study. Cytokines were measured with enz...

PURPOSE Macrophage migration inhibitory factor (MIF) is a pleiotropic, proinflammatory cytokine that mediates various immunoinflammatory processes. Ocular cicatricial pemphigoid (OCP) is an autoimmune disease in which affected conjunctivae show features of an immunoinflammatory disease. In this study, the role of MIF in the pathogenesis of OCP was examined. METHODS The expression of MIF in co...
