Adenocarcinoma Arising in the Conjunctiva With Periparotid Lymph Node Metastases

Cornea. 2020 Apr;39(4):519-522. doi: 10.1097/ICO.0000000000002241.


Purpose: To report a rare case of adenocarcinoma (ADC) arising in the conjunctiva which locally recurred and metastasized to the periparotid lymph nodes.

Methods: This is a single observational case report.

Results: A 79-year-old male patient was referred to us for a suspected recurrence of conjunctival carcinoma of the right eye. At presentation, we observed an elevated conjunctival lesion with corneal involvement. He was treated with neoadjuvant mitomycin C 0.04% eye drops, followed by surgical excision of the lesion, cryotherapy of the excision margins, and reconstruction with amniotic membrane graft. The tumor was histologically diagnosed as ADC. The negative systemic evaluation and the immunoprofile led us to believe the primitive nature of the tumor. The excision margins were positive, and the patient was lost to follow up for 7 months, and when he came back, a new local recurrence was diagnosed. Then, he received rescue treatment with mitomycin C 0.04% eye drops with complete regression of the lesion. No local recurrence was observed until the 14-month follow-up visit, during which the patient complained of swelling in the right parotid region. Subsequently, he underwent total parotidectomy with neck dissection. Metastasis was found in 3 periparotid lymph nodes. The patient did not receive further treatments, and no recurrences were observed over the following 20 months.

Conclusions: ADC arising in the conjunctiva is a very rare occurrence. Additional observation is required for the management of this rare conjunctival tumor.
