Summary
Amelanotic melanoma, a non-pigmented conjunctival cancer, presents as a pink tumor, delaying diagnosis. Early recognition of this rare malignancy is crucial for timely treatment and improved patient outcomes.
Area of Science:
- Ophthalmology
- Oncology
Background:
- Conjunctival melanoma is a rare malignancy, typically presenting as a pigmented nodule.
- Amelanotic variants are less common and appear as pink, smooth tumors, potentially hindering early detection.
Observation:
- A case study details an 82-year-old female with an amelanotic conjunctival melanoma.
- The tumor was diagnosed through cytological, histopathological, and immunohistochemical analyses.
Findings:
- The invasive amelanotic melanoma was confirmed by S-100 and MART-1 protein expression.
- Despite surgical and chemotherapy treatment, the patient progressed to metastatic disease within three years.
Implications:
- The lack of pigmentation in amelanotic melanoma can significantly delay diagnosis and treatment.
- Increased awareness among clinicians is vital for the early recognition and management of this rare conjunctival cancer.

01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
