Diffuse primary malignant melanoma after prior primary cutaneous malignant melanoma

|July 1, 1980
Summary
A man developed a diffuse choroidal tumor ten years after lip melanoma treatment. Histopathology revealed it was a primary choroidal melanoma, not a metastasis.
Area of Science:
- Ophthalmology
- Oncology
Background:
- Malignant melanoma can metastasize to various organs, including the eye.
- Distinguishing between primary and metastatic choroidal tumors is crucial for patient management.
Observation:
- A 64-year-old male presented with a diffuse choroidal tumor in his right eye.
- He had a history of primary malignant melanoma of the lip treated 10 years prior with excision and bilateral neck dissection.
Findings:
- Clinical presentation suggested metastatic choroidal melanoma.
- Histopathologic evaluation confirmed the tumor was a primary diffuse choroidal malignant melanoma, not metastatic from the lip.
Implications:
- This case highlights the importance of histopathologic confirmation for choroidal tumors, even with a history of cutaneous melanoma.
- Primary diffuse choroidal melanoma represents a distinct entity requiring specific diagnostic and management considerations.
