Presuturing--a new technique for closing large skin defects: clinical and experimental studies.

We have developed a new technique termed presuturing for aiding in the closure of large skin defects which may have otherwise required a skin graft or flap. This technique is based on biomechanical properties of skin (creep, stress relaxation) which allow skin to stretch beyond its inherent extensibility. Presuturing is performed under local anesthesia and consists of plicating intact skin over the area of planned excision the night prior to operation. Experimental studies in a pig model showed the decrease in force required to close a standard-sized wound to be 40.1 percent less than control (p less than 0.001). Fourteen patients who underwent wide excision of skin lesions had their wounds presutured. All but one wound could be closed primarily without undermining. Presuturing seems to be an easy and clinically useful technique in aiding the primary closure of large defects.

Hybrid biphenotypic acute leukemia with extreme hypodiploidy.

A patient diagnosed as having acute lymphoblastic leukemia (L2) relapsed 4 months later and was found to have morphologic and immunologic evidence of a biphenotypic hybrid acute leukemia. Chromosome analysis at relapse showed two abnormal clones, one with marked hypodiploidy and the other with exactly double the hypodiploid clone. It is considered that this is an example of a hybrid lymphoblastic/nonlymphoblastic leukemia with unique karyotype.
