[Contribution of the cryosurgery in the management of xeroderma pigmentosum].

Background: Basal cell carcinoma (BCC) occurs frequently in young patients with xeroderma pigmentosum (XP). Because tumours are multiple and usually found on the face, alternatives to surgery are proposed. The purpose of this study was to evaluate the efficacy of cryosurgery for BCC in XP patients.

A misdiagnosed nail bed melanoma.

Nail bed melanoma or subungual melanoma is frequently misdiagnosed compared to other melanoma in other anatomic sites. We report the case of a 48-year-old woman presenting with a dystrophic and pigmented lesion of her fourth finger nail. This initial presentation had been mistaken for onychomycosis, but biopsy of nail bed and nail matrix confirmed nail bed melanoma.

Trigeminal trophic syndrome: a report of two cases with review of literature.

Trigeminal trophic syndrome, a rare cause of facial ulceration, is the consequence of damage to the trigeminal nerve or its central sensory connections. We report two cases of trigeminal trophic syndrome, complications of cerebral vascular accidents. A 65-year-old woman complained of numerous and progressive ulcers of the right side of her face of 2 month's duration.
