Abstract
Uveal melanoma is the most common intraocular malignant tumor in adults. For patients presenting with cataracts and glaucoma, it is recommended to assess whether an intraocular lesion is present as the primary cause. The present study describes the case of a 52‑year‑old man with primary intraocular malignant melanoma. The patient experienced painless vision loss in the right eye for 1 year, with recent onset of eye swelling and pain in the week prior to seeking medical attention. A slit‑lamp examination revealed a shallow anterior chamber in the right eye, a visibly opaque lens and a faint reflection of the tumor surface in the vitreous humor. In addition, the intraocular pressure of this eye was >60 mmHg. Magnetic resonance imaging revealed a large tumor behind the lens measuring 16x18x14 mm. Pathological examination confirmed the diagnosis of malignant melanoma. No BRCA‑associated protein‑1 somatic mutation was detected, whereas germline mutations of MutL protein homolog 1, RAD54 like, and SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily a, member 4 were identified. Extensive systemic examination excluded the possibility that the tumors originated from another part of the body. The present case report highlights the crucial role of slit‑lamp examination in the detection of ocular tumors. It is advocated that for patients presenting with cataracts, attention should be paid to the possibility of intraocular tumors. Meticulous slit‑lamp microscopy may reveal a reflection of the surface of a malignant melanoma, preventing misdiagnosis.
