Amelanotic conjunctival melanoma in a child

PurposeMalignant melanomas of the conjunctiva are extremely rare in children. In this case report we present a conjunctival melanoma of a child. ObservationsWe report a case of a 7 years old boy who presented with a rapidly growing reddish lesion measuring 8mm in base × 2.5 mm in thickness on the nasal conjunctiva in his right eye. The patient underwent resection of the lesion (with 4 mm margins of the surrounding clinically normal conjunctiva) and cryotherapy to the adjacent conjunctival margins. Histopathology confirmed the diagnosis of conjunctival melanoma. Pathology also can be challenging; a review of pathology is advisable as happened in this case. Systemic workup was negative for metastatic disease. On 73 months of follow up, the patient was stable without local recurrence or secondary systemic disease. Conclusions and ImportanceMalignant melanoma can present de novo as an amelanotic rapidly growing conjunctival lesion in children. This case should raise the awareness of the variable clinical presentations, the challenging diagnosis, treatment and follow up of pediatric conjunctival melanoma.
