Child↗

Bilateral Ota naevus.

We present the case of a 22-year-old woman, who had presented since the age of 15 a pale-blue spot spread on the right-hand side of her forehead and in her bulbar conjunctiva (first and second branches of the trigeminus nerve), consistent with Ota naevus. A few years later another with similar characteristics appeared on the other side of her forehead, cheek and sclera. No deafness, neurological defect nor visual loss were detected. We comment on the rarity of this case because the patient is Caucasian and also we explain the main complications derived of this disease and consider the therapeutic options.

Cutaneous melanoma extirpated with insufficient surgical margins.

A major controversy in the treatment of melanoma is the width of the surgical margin necessary for complete excision. We have reviewed the case histories of 1125 patients at the Melanoma Unit of the Dermatology Department of the San Cecilio Clinical Hospital in Granada from 1988 to 2000. The first aim was to verify whether there is a statistically significant correlation between occupied margins and other prognosis factors. We also analyse the situation after re-excising the scar from the previous extirpation with a minimum margin of 1 cm.
