[Family Buschke-Ollendorff syndrome].

Buschke-Ollendorff syndrome is an autosomal dominant disorder whose clinical course includes elastic nevi and osteopoikilosis. Histologically, most cases present with a normal amount of collagen in the skin lesions and an increase in elastic fibers, although abortive forms with skin involvement have been described, with a decrease in elastic fibers and an absence of bone alterations. We describe the case of a 41-year-old woman with Buschke-Ollendorff syndrome criteria, and that of her 2-year-old daughter who might present an abortive form of Buschke-Ollendorff.

[Reflex sympathetic dystrophy: description of a case with skin lesions].

Reflex sympathetic dystrophy or algodystrophy is a poorly defined syndrome in which the patient develops pain disproportionate to the cause. It is included among the complex regional pain syndromes. The symptoms are triggered by some type of trauma, at times trivial, and consist of burning pain, edema, changes in skin color, alterations in vascularization, temperature changes, hyperhidrosis and skin disorders, which primarily consist of atrophic changes.
