a systemic disorder, the management of which usually requires treatment with potentially toxic agents on an Inpatient basis. Metabolic, infective and other complications often require considerable input from other Specialists. Hospital access is becoming increasingly problematic for those suffering acute skin disease. This trend has important implications for both patients and Dermatologists in the management of Erythrodermic Psoriasis.

In the past decade the pulsed tunable dye laser has been shown to be of considerable benefit in the treatment of congenital cutaneous vascular naevi. However it is important to recognize that not all lesions will respond to treatment, and that many will only do so to a limited extent. At present there are few reliable predictors of response. Patients may be treated at any age, and the psychological benefits of successful treatment can be immense, even in those whose response is only partial.

“Q-Switching” where high energy levels [5-10 J/cm*] are delivered in ultrashort pulse widths [ 10-80 ns] has offered significant advances in the laser treatment of tattoos and pigmented lesions. Ruby [wavelength 694 nm], Nd:YAG [lo64 nm, 532 nm] and Alexandrite [755 nm] lasers have been widely used for these disorders. In tattoos, best results are achieved in amateur, blue-black lesions. Epidermal pigmented disorders such as benign lentigines and cafe au lait macules can lighten satisfactorily. Dermal pigmented lesions such as naevus of Ota may require a prolonged course of therapy. There is insufficient longterm data concerning laser therapy of congenital melanocytic naevi to recommend this form of treatment. Results of treating both tattoos and pigmented lesions will be presented and recent developments in this field reviewed. WS093
The Erb:Yag-laser - A new technique in skin-photoablation
H. Tiel. Praxisfir Dermatological
Dermatologie und Venerologie, Laser-Center of Berlin, Berlin, Germany
Since years the cw-and superpuls, lately the Ultrapuls COz-Laser has become the “gold standard” for ablation of skin lesions such as seb. keratoses, lentigines, age-spots and wrinkles (face-resurfacing).

Ackerman
We used the Erb:Yag-laser with its 2.94 wrn wave-length for photoablation of the skin. This laser, which has an absorption-maximum-peak in water, epidermal disorders such as seb. keratoses, age-spots, dermal nevi are simply removed with minimal thermal damage. For using this laser in face-resurfacing post-operative redness disappears within 10 days after treatment. Minimal bleeding occurs when deeper skin-layers are removed because of the missing thermal effect but the woundhealing is much shorter when using the Ultrapuls-CO*-laser. Thus using the Erb:Yag-laser is an elegant way in skin-ablation.

Several techniques for laser assisted hair removal have been introduced recently. These include treatment with the free running ruby laser at 694 nm, treatment with the long pulse infra red laser as 755 nm, treatment with the Q-switched frequency doubled Nd-YAG laser at 1064 nm in conjunction with a black dye, and even the use of delta-amino leavulinic acid in conjunction with red light 630 nm. The results of treatment depend on many factors, including the wavelength of light used, the beam diameter, the pulse duration, the size and degree of pigmentation of the hair and whether the hair is in anagen or telogen. The proportion of hairs in anagen vary considerably over different body areas and it is important in future that results are standardised with regard to treatment site and hair cycle phase. There are few good long term data on the effectiveness of laser assisted hair removal. The long pulse infra red laser utilising tbermokinetic selectivity rather than selective photothermolysis looks to offer the most promise, maximising hair destruction whilst minimising side effects, on other skin structures.

Solar keratosis is not a premalignant lesion but a malignant neoplasm, i.e., a squamous cell carcinoma. And that is the reason why no textbook of dermatology, general pathology, or dermatopathology has ever stated cogently, or ever will, where solar keratosis ends and squamous cell carcinoma begins. Solar keratosis is an incipient squamous cell carcinoma. And that is precisely why “Darier type” solar keratosis is “pseudoglandular” squamous cell carcinoma in miniature. Solar keratosislsquamous cell carcinoma is a continuum. And that is precisely the reason why the cytologic features of the neoplastic cells of solar keratosis are indistinguishable from those of thicker squamous cell carcinomas. The two conditions, despite their different names, are fundamentally one and the same.
