Paraneoplastic ocular sarcoid-like reaction in the setting of pulmonary sarcoid-like reaction and lung adenocarcinoma: A case report and literature review.

PURPOSE: To describe ocular sarcoid-like reaction as a unique manifestation of paraneoplastic syndrome in the context of concurrent pulmonary sarcoid-like reaction and lung adenocarcinoma.

METHODS

Single case report and narrative review.

RESULTS

A 59-year-old male patient presented with a year-long history of diminished vision and weight loss. Clinical examination revealed panuveitis and multiple chorioretinal lesions. A CT scan of the chest revealed mediastinal and hilar lymphadenopathy as well as a spiculated right lower lung nodule concerning for malignancy. Subsequent bronchoscopy and biopsy confirmed lung adenocarcinoma and non-caseating granulomas in sentinel lymph nodes.

CONCLUSION

Although pulmonary granulomatous reaction can be seen in the setting of lung malignancy, and ocular sarcoid-like reaction may present as a paraneoplastic manifestation of systemic malignancy, the presence of concomitant pulmonary and ocular sarcoid-like reactions distinguishes this case. The findings underscore the importance of a systemic workup for patients with concerning constitutional symptoms, as paraneoplastic syndromes and metastatic diseases may mimic uveitis. Recognition of paraneoplastic sarcoidosis as a potential clinical manifestation is essential, especially in patients with chronic illness indicators, necessitating a comprehensive evaluation for malignancy.
