PURPOSE: Surface tumors of the eye comprise an ample spectrum of diseases with various clinical manifestations. Diagnosis has been traditionally achieved through core biopsies, but cytology is an innovative, fast, and minimally invasive method. The objective of this study was to investigate the use of exfoliative cytology as an alternative method for the detection of ocular surface squamous neoplasm (OSSN). METHODS: Exfoliative cytology of the lesions was performed by collecting smears using plastic brushes followed by smearing the cells onto slides and subsequently fixing them in 90% alcohol...

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 with conjunctival keratoacanthoma who had no known risk factors such as skin disorders, trauma, surgery, or infection...

An 85-year-old male presented with painless bulging lesion over the cornea. Clinical history, diagnostic imaging studies, and histopathologic sections were evaluated. The patient clinically displayed an vascularized conjunctival lesion located at the superior bulbar conjunctiva with extension onto cornea covering 2/3 of his pupillary aperture superiorly. His visual acuity was counting fingers at 4 m. The patient underwent a total excision of the lesion including conjunctival and corneal parts. Histopathologic evaluation revealed spindle cell carcinoma which involves the whole conjunctival squamous epithelium with significant polarity loss, nuclear enlargement with hyperchromasia and pleomorphism, and mitotic activity...

An 8-year-old healthy boy underwent surgery for excision of a painless, enlarging vascularized conjunctival tumor. Histopathology disclosed a mass comprised of interweaving spindle cells and scattered histiocytes in a fibrous matrix, consistent with benign fibrous histiocytoma. This rare tumor can resemble several conditions, including scleritis/episcleritis, inflamed pterygium, juvenile xanthogranuloma, foreign body granuloma, solitary fibrous tumor, amelanotic melanoma, and squamous cell carcinoma.

Squamous cell carcinoma of the conjunctiva is the most frequent malignant tumor of the ocular surface. It is a rare disease with an incidence of 0.13 to 1.9 per 100,000 inhabitants, mainly affecting individuals between 50 and 75 years of age. It tends to have a slow, non-aggressive course. Treatment depends on the extent of the tumor. If there is intraocular involvement, enucleation is indicated, and in the presence of extraocular involvement the orbital exenteration is the standard treatment. We report and discuss the case of an 82 year old male patient having a conjunctival squamous cell carcinoma with intra and extraocular involvement, together with a review of the literature...

BACKGROUND: Patients with xeroderma pigmentosum (XP) are strongly predisposed to the development of numerous cutaneous cancers. However, the extent of ocular pathology in these patients has not been adequately studied. METHODS: We conducted a retrospective study of tumors involving the ocular surface and ocular adnexa from 6 XP patients. Histopathological evaluation and immunohistochemistry was performed using antibodies directed against the most common mutated proteins in XP (XPA, XPC, and XPD)...
