Excision of XXXX without wound closure.

@entity1 @entity5 @entity1489 @entity406 @entity532 @entity1491
Sixty-two @entity1 with 67 large or poorly defined @entity1489 predominantly on the head and neck (58 @entity1491 ) were treated by excision of the lesion and allowing the defect created to heal by second intention. Histological control of the adequacy of excision was monitored using routine vertical sections of @entity406 -fixed tissue. Further re-excisions were performed in 17 @entity1 in whom @entity5 extended up to or within 1 high power field (approximately 0.44 mm) of the excision margin. The @entity406 -fixed specimens ranged from 6-60 (mean 21) mm in diameter and 2-12 (mean 5) mm in depth. After one excision the time to complete re-epithelialization was directly proportional to the surface area (r = 0.73) and ranged from 13 to 60 days (mean 33 days). Measurements of the movements of fixed reference points tattooed at the wound edges in six @entity1 showed that movement of surrounding tissue into the defect accounted for 39-62% (mean 45%) of the reduction in surface area of the defect during healing. @entity532 were rare and the cosmetic results were considered good or excellent in 48 @entity1 , fair in nine and poor, i.e. requiring corrective surgery, in three @entity1 . Poor results were due to distortions of free margins, e.g. lower eyelid and nasal margin. The major benefit of this technique is the ease with which further excisions can be performed when histologically indicated.(ABSTRACT TRUNCATED AT 250 WORDS)
