Differentiation of Pigmented Conjunctival Squamous Cell Carcinoma From Melanoma

Abstract Aim: Conjunctival squamous cell carcinoma (SCC) is a rare tumour of the ocular region and microscopic radical surgical is difficult. There are no single guidelines for therapeutic management and the role of radiation therapy is not clearly defined although conventionally photon or electron beams are used. Proton beam radiotherapy (PBRT) is a new option for a conservative approach and allows good sparing of the organs at risk. Materials and methods: After surgical resection, we collected 15 cases treated at our institution with PBRT. The dose delivered was between 48 and 60 Gy relative biological effectiveness (RBE), with fractions of 12–15 Gy RBE. Results: After an average period of 48 months, the patients achieved excellent disease control (overall survival and disease-free survival: 86·6%), with minimal acute and late toxicity. Findings: In this work, we present our experience on the use of PBRT technique in SCC treatment. A larger sample of patients is needed to draw conclusions about the impact of this treatment on disease recurrence and overall survival.

The One

A 41-year-old male presented with a large non-pigmented lesion on the ocular surface involving 8 clock hours of limbus, bulbar conjunctiva, and palpebral conjunctiva. Incisional biopsy confirmed poorly differentiated conjunctival squamous cell carcinoma (SCC). It was staged as a T3, N0, M0 lesion. Treatment was with surgical excision, amniotic membrane transplant, and buccal mucosa graft. Three weekly cycles of 0.04% mitomycin C were administered postoperatively. Six months following excision, although there was no evidence of residual conjunctival SCC, the patient suffered from poor vision, significant pain, and diplopia due to severe dry eye, limbal stem cell deficiency, and symblepharon.This case illustrates the difficult clinical decisions which confront the clinician when treating conjunctival SCC, particularly with balancing the need to eradicate the disease to prevent local invasion and metastatic spread on the one hand and minimising ocular morbidity on the other.

Objectives: To evaluate 20 patients with squamous cell carcinoma of the conjunctiva. To determine the clinical andpathological characteristics. Design Retrospective study. Setting: POF hospital & EDO eye hospital Wah.Cantt Period: From June 200 toJuly 2006. Methods: The patients presenting with squamous cell carcinoma of the conjunctiva were retrospectively evaluated. Results: Patientswere usually male (80%), elderly (75% >60 years of age), with most lesions (90%) occurring at the limbus. Two patients (10%) sufferedrecurrence of the squamous cell of the conjunctiva within 2 to 4 months of resection. Corneal invasion was noted in two patients (!0%) whilethere was intraocular and orbital invasion in two patients (10%). One patient (5%) required enucleation and one patient (5%) requiredexenteration. In situ carcinoma was noted in 18 patients (90%). Conclusions: Squamous cell carcinoma of the conjunctiva occurs in the sunexposed area of the conjuntiva at the limbus in the elderly men. Recurrence was noted in the younger patients and with larger lesions.Enucleation and exenteration is required in a small number of cases.
