The clinical presentation and treatment of an invasive conjunctival squamous spindle cell carcinoma

Ocular surface squamous neoplasia represents neoplastic epithelial abnormalities of conjunctiva and cornea, ranging from squamous dysplasia to invasive squamous cell carcinoma and is both sight- and life-threatening. Squamous spindle cell carcinoma (SSCC) of conjunctiva is a rare variant with distinct behavior which is thought to be more locally aggressive. We describe an 83-year-old woman with a progressively enlarging huge SSCC in her right eye over the past 2 years. The tumor bulged out with local invasion into intraocular and orbital cavities. Wide excision of the tumor with frozen section control was performed. After surgery, topical 0.03% mitomycin C was given as adjuvant therapy. At 40-month follow-up, the lesion site showed no evidence of local recurrence. This case provides a valuable and complete experience of the clinical presentation for the progression and treatment of this rare disease.
