Fibrodysplasia ossificans progressiva and corneal keloid

Pseudopterygium: An Algorithm Approach Based on the Current Evidence

Pseudopterygium is a non-progressive conjunctival adhesion to the peripheral cornea secondary to a corneal-limbus damage. According to the literature, the main etiology is a previous eye trauma. Nevertheless, this could be biased by the existence of other underdiagnosed causes of pseudopterygium, some of which may have severe consequences for the integrity of the eye and patient’s life. This comprehensive literature review was performed based on a search on the PubMed and Google Scholar databases of relevant pseudopterygium published papers according to our current knowledge and seeks to gather the existing evidence about its diverse etiologies and clinical features, as well as to propose a diagnostic algorithm to simplify its correct approach.

Corneal keloid presenting forty years after penetrating injury: Case report and literature review

A 64-year-old Caucasian man had been diagnosed with presumed ocular surface squamous neoplasia in the left eye and started on topical interferon alpha 2b drops. When we saw him, he provided a history of penetrating corneal injury more than forty years before. Slit lamp examination revealed a large, elevated, opaque lesion involving the left cornea. High-definition anterior segment optical coherence tomography revealed a hyperreflective lesion involving the anterior stroma with a relatively normal overlying epithelium. Based on the clinical history, slit lamp, and anterior segment optical coherence tomography findings, a giant corneal keloid was suspected, and the interferon drops were discontinued. He subsequently underwent a penetrating keratoplasty, and histopathologic analysis was consistent with corneal keloid. Corneal keloids may be seen decades after the initial trauma, and anterior segment optical coherence tomography can be a useful tool in differentiating these tumor-like lesions from other neoplasia.

Giant corneal keloid: case report and review of the literature

PURPOSE

To report a patient with a tumor-like corneal keloid.

METHODS

Retrospective review of clinical features and histopathologic findings.

RESULTS

A 68-year-old woman with a remote history of an orbital tumor treated with radiation developed a corneal tumor. A biopsy of the tumor showed fibrocellular tissue, and her blind painful eye was enucleated. Pathologic findings in the enucleated eye showed that the corneal mass was consistent with a large keloid.

CONCLUSIONS

A corneal keloid may clinically appear as a large corneal tumor.

Unilateral Congenital Corneal Keloid With Anterior Segment Mesenchymal Dysgenesis and Subluxated Lens

PURPOSE

To report the unusual association of unilateral congenital corneal keloid with anterior-segment mesenchymal dysgenesis and bilateral subluxated lens.

METHODS

A 20-year old man presented with a mass lesion involving the left cornea. The corneal lesion had been present since birth. On biomicroscopic examination, a well-defined vascularized, grayish-white mass occupying the whole of the left cornea was seen. The right eye showed multiple peripheral corneal opacities with iridocorneal adhesions, a poorly defined supranasal limbus, and a subluxated lens. Excision biopsy of the mass was done for histopathologic examination.

RESULTS

Histopathologic examination of the excised corneal mass showed features consistent with that of a corneal keloid: thickened keratinized epithelium, absent Bowman membrane layer, and fibrovascular hyperplasia composed of hyalinized collagen fibers with irregular orientation of the collagen lamellae. During penetrating keratoplasty of the left eye, an anomalous iris pattern with poorly defined angle and a supranasal subluxated lens was also observed. Extraction of the subluxated lens was also done. The graft failed subsequent to a nonhealing persistent epithelial defect.

CONCLUSION

Our case report highlights the rare association of a unilateral congenital corneal keloid with anterior-segment mesenchymal dysgenesis and bilateral subluxated lens.
