Lung metastasis with primary conjunctival mucoepidermoid carcinoma.
Article in Romanian journal of ophthalmology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Mucoepidermoid carcinoma of the conjunctiva is a rare, aggressive variant of squamous cell carcinoma, with limited reports of systemic metastasis. Case presentation: An 86-year-old man presented with a suspicious conjunctival lesion. Initial biopsy was inconclusive, but excision confirmed moderately differentiated mucoepidermoid carcinoma. Despite treatment, the tumor showed rapid orbital invasion. Imaging later revealed bilateral lung and liver metastases. Cytology confirmed metastatic spread. The patient died two months later. Discussion: Mucoepidermoid carcinoma of the conjunctiva is an uncommon and particularly aggressive variant of ocular surface squamous neoplasia, often underdiagnosed due to its mixed histological components. Compared with classic squamous cell carcinoma, it demonstrates higher rates of local recurrence, deeper orbital invasion, and a greater potential for regional spread. Although distant metastasis is exceedingly rare, our case illustrates that this subtype may disseminate rapidly and extensively despite early intervention. These findings highlight the importance of performing deep biopsies to avoid sampling error, ensuring complete histopathological assessment, and considering early systemic imaging when tumor behavior appears unusually aggressive. Conclusion: Conjunctival mucoepidermoid carcinoma may exhibit aggressive local and systemic behavior. Early deep biopsy, complete histological analysis, and systemic imaging are essential to guide appropriate management and detect rare but fatal metastases.
