Purpose: Conjunctival melanoma is a rare ocular tumor. We report a case of ocular conjunctival melanoma during topical immunosuppression, after a corneal transplant from a donor with metastatic melanoma.
Observation: A 59-year-old white male presented with a progressive nonpigmented conjunctival lesion in his right eye. He had previously undergone two penetrating keratoplasties, and he was being treated with topical immunosuppression with 0.03% tacrolimus (Ophthalmos Pharma; Sao Paulo, SP/Brazil). The histopathology evaluation revealed the nodule to be a conjunctival epithelioid melanoma. The donor's death cause was disseminated melanoma.
Conclusion And Importance: The correlation between cancer and systemic immunosuppression after a solid organ transplant is widely known. The local influence, however, has not been reported. In this case, a causal relationship was not established. The correlation between conjunctival melanoma, exposure to topical tacrolimus immunosuppressive therapy, and the malignance characteristic of donor cornea should be better evaluated.

Aims: Limited studies have been conducted on juvenile conjunctival nevus (JCN) in Asian populations. This study aims to investigate the clinical and pathologic characteristics of JCN cases among the Han ethnicity in northwest China, providing insights for pathologists and ophthalmologists in diagnosing this condition.
Methods: A subset of conjunctival nevi in children and adolescents, characterized by a confluent growth pattern and lack of maturation, was identified and defined as JCN.

Background: The ocular surface is directly exposed to environmental influences. Noxae that have already been identified for the ocular surface are heat, air dryness, pollutant gases, fine dust particles and ultraviolet radiation.
Methods: The current literature was used to investigate the relationship between frequent ocular surface diseases and various environmental factors and to analyze their development over the years.

Conjunctival malignant melanoma is extremely rare, with no standard of care established at moment. Here we report a 65-year-old woman, as a hepatitis B virus (HBV) carrier, who presented concurrently a liver mass and lower bulbar conjunctival pigmented lesions in the right eye. Needle liver biopsy and excisional conjunctival biopsy showed hepatocellular carcinoma and conjunctival malignant melanoma , respectively.
