We describe the case of a patient with prostate cancer, ascites, omental and bone metastases, an extremely rare clinical variant that warrants further investigation, and review the relevant literature.
PurposeWe describe two patients with squamous cell papilloma of the conjunctiva due to human papilloma virus (HPV) and review the literature.Patients and methodsTwo patients with conjunctival tumors were examined and treated in the University Eye Clinic and diagnosed in the University Pathology Department, University Hospital of Ioannina, Greece. The first patient was a 48-year-old man presenting with an extended papillomatous lesion in bulbar conjunctiva covering part of the cornea of his right eye. The second patient was a 24-year-old man presenting with a polypoidal papillomatous lesion on the caruncle of his right eye. The two lesions were removed surgically, cryotherapy was applied to the adjacent conjunctiva, and topical mitomycin-C was used. The amniotic membrane was used to restore the conjunctival defect in the first patient. The two removed lesions were sent to the Pathology Department for histopathological examination. Immunohistochemistry, DNA in situ hybridization, and polymerase chain reaction (PCR) analysis were performed.ResultsIn the first patient, histopathology showed the presence of a benign squamous papilloma with koilocytosis. DNA in situ hybridization with broad-spectrum probes showed that this patient was positive for HPV DNA. In the second patient, histopathology showed the presence of a squamous papilloma with mild dysplasia and koilocytosis. Immunohistochemical analysis was positive for HPV protein and p16 protein. DNA in situ hybridization with broad-spectrum probes showed that the patient was positive for HPV DNA. PCR analysis showed the presence of HPV 6. According to morphological and molecular findings, both patients were diagnosed with squamous cell papilloma due to HPV.ConclusionHPV can infect the ocular surface. According to clinical results, the ophthalmologist in cooperation with the pathologist can recommend appropriate laboratory examinations to confirm the diagnosis and successfully treat conjunctival papillomas.
Primary non-Hodgkin's lymphomas of the conjunctiva are uncommon. They are almost exclusively extranodal marginal zone B-cell lymphomas/mucosa-associated lymphoid tissue lymphomas. In this study, we report an extremely rare case of conjunctival mantle cell lymphoma in a 78-year-old man, presenting as a unilateral epibulbar mass.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
