Malignant melanomas are well known to arise from nevi or diffuse melanosis at the limbus*'^ and surgical or physical trauma is believed to induce such metaplasias.* Precise diagnosis is often erroneously based only o n clinical findings.'

CASE REPORT C. Κ., a 50-year-oId Caucasian woman, was first seen at the Department of Ophthalmology July 8, 1963, exhibiting a large mass attached to the right eye and telling a history o f recurrent tumors at the same site. The patient related that she was first examined by another surgeon in 1959 and an epibulbar tumor was diagnosed. In 1961, the epibulbar growth was removed. Some time (which the patient was unable to specify) later the tumor recurred at the same site, show­ ing a more pronounced rate of growth. A second operation, performed in 1962, con­ sisted of removal of the limbal mass and dia­ thermic cauterization of the sclerocorneal bed. Again it recurred in a much shorter time, attaining a bigger size than ever. The patient related that vision was still good at that time. In August, 1962, a third operation was done. The recurrence was quick and the tumor has in­ creased in size, protruding out of the lid fissure and considerably impairing the vision of the right eye. Closure of the lids was impossible. A t the time of examination vision was: R.E., 0.2; L.E., 0.8. Eye ductions were limited on the right side downward and outward. A big bluish mass (1.5 by 1.5 cm.) inserted on the lower limbus, prolapsed outward from the lid fissure, partially covering the

pupillary area. Its surface showed necrotic points. Intense pigmentation of the whole limbus extended up to the lower fornix. Slight Chemosis and con­ gestion of the conjunctiva were present. The right pupil reacted normally to light and digital tension was thought to be normal. A provisional diagnosis of epibulbar pigmented tumor was made and the patient was admitted for further study. General health and laboratory tests revealed no abnormal findings, only an aortic ectasia being discovered. On July 13, the tumor was removed under general anesthesia. The dissection of the mass was not difficult but the fragile limbal insertion ruptured under slight traction and was followed by copious bleeding. A conjunctival flap was slid over the naked area and the postoperative course was eventless. On July 19, the pathologic examination was received. A spindle-cell malignant melanoma was diagnosed. On July 20, the right eye was enu­ cleated, special care being taken to remove as

much conjunctiva and episclera as possible. No sutures were laid and the cavity was filled with a furacin-soaked dressing. Five days later, the patient was transferred to the radiotherapy de­ partment. On July 26, the pathologic examination of the eye revealed a spindle-cell malignant melanoma circumscribed to the limbus without extension to the inside of the eye, but compromising the whole circumference of the limbus. A total of 3.5 r of X-rays were given, divided into 14 sessions. SUMMARY A
