Abstract Details

Purpose:

To describe a rare case of a recurrent melanoma of the conjunctiva with corneal invasion, in a female patient.

Setting:

Department of Ophthalmology, Centro Hospitalar de São João Hospital, Porto, Portugal

Methods:

Clinical and imaging description of a clinical case.

Results:

Female patient, 47 years old, presented to the emergency department due to sudden growth with a week of evolution of conjunctival nevus that she reported having had in the right eye for several years. No major precedents. Visual acuity was 8/10, intraocular pressure of 13 mmHg and biomicroscopy identified an exophytic temporal conjunctival melanotic tumor, with conjunctival nutritive vessels. Fundoscopically and in mode B ultrasound, without changes. Surgical excision of the lesion was performed, with histological result of conjunctival melanoma. The systemic study did not reveal the presence of metastasis. After 2 years, the appearance of a non-pigmented lesion in the conjunctiva is identified, affecting the cornea. Penetrating eccentric transplant involving cornea and sclera was performed. Histologically, corneal recurrence of melanoma was identified.

Conclusions:

Surgical excision combined with reconstruction with penetrating corneal transplantation may be a treatment for conjunctival malignant lesions with corneal invasion. Although rare, conjunctival malignant melanoma is extremely aggressive with high rates of metastasis and mortality, so a multidisciplinary approach should be performed from patients.
