Clinical and histopathological features of proliferative corneal lesions in Cyprininae fishes: Implications for treatment and insights into corneal tumors. Vet Ophthalmol 2024; 27:200-213. [PMID: 37485736 DOI: 10.1111/vop.13133] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Revised: 07/10/2023] [Accepted: 07/14/2023] [Indexed: 07/25/2023]
Abstract
Captive fish populations, such as those encompassing aquarium and pet fish, offer significant economic value and are integral to conservation, research, and education. However, these ornamental fish exhibit a reduced ability to protect their ocular surfaces, and our understanding of the ocular diseases that affect them remains limited. Although corneal neoplasms in carp are uncommon, identifying their distinct characteristics is crucial in selecting appropriate therapeutic interventions that aim to preserve vision, prevent the ocular loss, and ultimately ensure the survival of the affected fish. This study provides clinical and histopathological details of various proliferative corneal masses in Cyprininae species, including five koi (Cyprinus carpio) and four goldfish (Carassius auratus). It discusses a spectrum of neoplasms, including soft tissue sarcoma, spindle cell sarcoma, chromatophoroma, and papilloma, in addition to conditions like exuberant granulation tissue and proliferative carp pox. These findings bear significant implications for clinical decision-making and treatment, offering valuable insights into the incidence and characteristics of corneal tumors in captive fish, which could inform further studies in this area.

[PMID: 36413443 DOI: 10.1111/vop.13041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Revised: 10/31/2022] [Accepted: 11/09/2022] [Indexed: 11/23/2022]
Abstract
A 6-year-old miniature Shetland pony mare was referred for evaluation of a left corneal mass, which developed from the healing tissue of a corneal traumatic ulceration that had occurred 4 weeks previously. On gross examination, a spherical, smooth-surfaced, and pink-colored lesion of about 1 cm in diameter was protruding from the left palpebral fissure. Ophthalmic examination revealed that it was attached to the scar tissue of the cornea, and that one corpora nigra was adherent to the posterior face of corneal wounded area, without sign of uveitis. The remainder of the ophthalmic examination was unremarkable. The mass was excised, and cryotherapy was used as an adjunctive therapy. Histopathology of the resected mass was consistent with a pyogenic granuloma on the basis of radially oriented proliferating capillaries, embedded in immature granulation tissue containing an infiltrate of neutrophils, plasma cells and eosinophils. There were no histological features of malignancy. 2 months after surgery, the ventral part of the fibrotic corneal scar was slightly raised by a pink tissue, suggesting possible recurrence of the initial lesion. A second cryotherapy was performed over the leukoma area. No recurrence has been noted for a follow-up period of more than 25 months. Pyogenic granuloma is a benign proliferative fibrovascular response that typically develops after trauma or surgery. Corneal involvement is rare in humans, and to the authors' knowledge has never been documented in veterinary ophthalmology.

Br J Ophthalmol 2019; 103:1469-1474. [DOI: 10.1136/bjophthalmol-2018-312960] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2018] [Revised: 09/26/2018] [Accepted: 11/11/2018] [Indexed: 12/19/2022]
Abstract
AimsTo systematically describe the clinical and histopathological features of a case series of conjunctival carcinomatous lesions underlying as—and also masquerading—pyogenic granuloma.MethodsNine cases of conjunctival carcinomatous lesions underlying a pyogenic granuloma (which were clinically predominant) were retrospectively identified. Patients’ records were analysed for demographic data, clinical appearance and the postoperative course. Formalin-fixed paraffin-embedded specimens were routinely processed and stained with H&E and periodic acid-Schiff. Immunohistochemical stains for cytokeratin were performed in selected cases.ResultsAll nine tumours were located in the conjunctiva (bulbar, tarsal, limbal conjunctiva) of patients between 44 and 80 years. The lesions exhibited clinical features of pyogenic granuloma which dominated the clinical appearance. Additional features comprised a papillomatous appearance of the adjacent conjunctiva, a more whitish aspect of the lesion and a history of squamous cell carcinoma (SCC) respectively surgery for other entities. Histopathological analysis revealed a carcinomatous lesion (conjunctival intraepithelial neoplasia or SCC) at the base of a classic pyogenic granuloma in all nine cases. Surgical removal (R0 resection) was performed. Three cases received adjuvant mitomycin C or interferon α2b treatment. Two lesions locally recurred within 2 years after initial presentation.ConclusionCarcinomatous lesions may be accompanied by a pyogenic granuloma which may dominate the clinical pictures. As the tumour is usually located at the base of the lesion, a complete surgical excision followed by histopathological analysis is mandatory for each lesion appearing as conjunctival pyogenic granuloma.

Abstract
Background Pyogenic granuloma is an excessive proliferation of granulation tissue that usually develops after minor trauma or surgery. Ocular involvement usually happens on the external surface and cornea is rarely involved. The objective of our report is to describe the clinicopathological feature of this rare disease and give insight on clinical features that help in the diagnosis. Case Report This report presents a case of a four year old child who had fleshy growth of one week duration on the right eye after seven weeks of pain and redness. Slit lamp examination showed vascularized central corneal mass with surrounding stromal infiltrates. The mass was excised, and histopathological examination confirmed pyogenic granuloma of the cornea. Conclusion Corneal pyogenic granuloma could be a rare complication of infectious keratitis. Therefore, it should be considered as a differential diagnosis in corneal mass especially after an infection or trauma.
