Adenoid squamous carcinoma of the conjunctiva—a clinicopathological study of 14 cases

Abstract

AIMS—In order to determine the clinicopathological features and optimum management of a series of patients with adenoid squamous cell carcinoma of the conjunctiva, all cases of squamous cell carcinoma (SCC) of the conjunctiva and cornea on file in the registry of the ophthalmic pathology at the Armed Forces Institute of Pathology were reviewed.
METHODS—On histopathological examination, a predominant adenoid or pseudoglandular pattern due to islands of neoplastic squamous or epidermoid cells surrounded by acantholytic cells was necessary for inclusion in the study. Histochemical and transmission electron microscopic studies (TEM) were performed. Clinical features of all the patients were extracted from the charts.
RESULTS—The anatomical location of the 14 tumours was corneoscleral limbus (seven patients) and bulbar conjunctiva (seven patients). Eight patients presented with inflammatory signs and irritation (red eye, tearing, foreign body sensation), while six patients developed a slowly growing, painless mass. Histochemical and TEM studies showed extracellular hyaluronic acid and no intracellular mucin. Of the two patients initially treated by enucleation, one was free of disease after 2 years while the second patient had recurrence in the socket and died of brain metastases despite wide orbital excision and radiotherapy. All five patients with recurrent tumours initially had irritated red eyes and two required enucleation. One such patient, after orbital exenteration and radiotherapy, died of unrelated disease.
CONCLUSION—The study demonstrates that adenoid SCC of the conjunctiva often presents with inflammatory signs. The tumour is locally aggressive and may metastasise and should, therefore, be histopathologically differentiated from the less aggressive conventional squamous cell carcinoma. Optimum treatment includes wide excision with documented histological clear margins of resection on permanent sections and frequent follow up.
