Lichenoid tissue reaction in porphyria cutanea tarda.

We report a patient presenting with lichenoid plaques on exposed skin who had the metabolic features of porphyria cutanea tarda (PCT). Histology of lesional skin demonstrated a lichenoid inflammatory cell infiltrate in the upper dermis, while direct immunofluorescence revealed immunoreactive colloid bodies. Monochromator irradiation testing demonstrated photosensitivity in the visible spectrum consistent with porphyria. Solar-simulated irradiation induced a papular reaction with lichenoid histological changes. We propose that this atypical presentation of PCT may reflect a lichenoid tissue response to a porphyrin-mediated photochemical reaction.

Malignant acanthosis nigricans: potential role of chemotherapy.

Acanthosis nigricans is an uncommon skin condition characterized by hyperkeratosis and skin hyperpigmentation. Most causes are benign, but it may also be associated with gastrointestinal and other malignancies. When associated with malignant disease, the skin pathology may be more severe and treatment often unsuccessful. We describe a 66-year-old man with acanthosis nigricans associated with carcinoma of the stomach, with distressing generalized cutaneous, perioral and perineal disease, whose skin condition resolved completely with combination chemotherapy. In patients with malignant acanthosis, chemotherapy may relieve many of the distressing cutaneous symptoms. A close liaison between gastroenterologists, dermatologists and oncologists is required.

Lupus erythematosus with antiphospholipid syndrome and erythema multiforme-like lesions.

The occurrence of erythema multiforme (EM) in patients with lupus erythematosus (LE) has been described previously as a coincidental association. In contrast, LE with EM-like lesions and a peculiar immunological pattern, including positive rheumatoid factor, antinuclear antibodies and a serum antibody against an extract of human tissues recently recognized as similar to Ro (SSA), constitutes an established entity named Rowell's syndrome. We describe a woman with LE and long-standing widespread vesiculobullous and necrotic haemorrhagic EM-like lesions in combination with Ro (SSA) and scl-70 antibodies and the typical laboratory findings of the antiphospholipid syndrome (APS), namely lupus anticoagulant, anticardiolipin antibodies and prolonged activated partial thromboplastin time. This case could conceivably be consistent with a diagnosis of Rowell's syndrome, if the latter is regarded as a clinicopathological spectrum. However, the coexistence of LE, persistent EM-like disease and incomplete APS may also fulfil the diagnostic criteria for the 'multiple autoimmune syndromes'. We speculate that the laboratory markers of APS play a pivotal part in such an unusual clinical presentation.

Cutaneous lupus erythematosus-treatment with pulsed dye laser.

Because of its vascular selectivity, the flashlamp-pumped pulsed dye laser (585 nm) is efficacious in the treatment of vascular lesions and is successfully used for the treatment of port-wine stains and haemangiomas in children. Based on the encouraging results with these cutaneous vascular disorders, the cutaneous lesions of patients with lupus erythematosus (LE) have now also been treated with the pulsed dye laser. Cutaneous lesions in lupus erythematosus are often difficult to treat with readily available local therapeutic methods. We report here on a group of 12 patients whose LE lesions were treated with the pulsed dye laser. In 10 patients, the LE was limited to the skin, while two patients had systemic LE (SLE). Even in the two patients with SLE, a significant improvement of skin lesions was achieved. After a mean number of 51 laser sessions, a median clearance rate of 70% was attained for nine patients. In one case, the laser treatment failed to clear the lesions. Two patients did not show any visible improvement of the lesions, but pain and itching were significantly reduced. There were few side-effects. No prolonged laser-induced scarring occurred and in only two patients was hyperpigmentation seen, which had resolved completely after 4 and 5 months, respectively. During a median follow-up of 7 months (range: 3-32 months), only one patient (after a complete clearance of the skin lesions) had a small relapse. In summary, the pulsed dye laser is an effective therapy for the treatment of superficial skin lesions in LE.

Face dermatitis from contaminants on a mask for anaesthesia.

Allergic and irritant contact reactions to face masks for anaesthesia have rarely been reported. We present a 55-year-old female patient who developed facial allergic contact dermatitis after an operation requiring general anaesthesia. Patch tests showed positive reactions to cocospropylenediamin-guanidinium-diacetate (trivial name Dodigen 3558), a preservative used in disinfectants for medical instruments. It could be proven that residues of the causative allergen in the disinfectant adhered to the mask. This is the first report of a clinically relevant sensitization to this increasingly widely used agent.

Phacomatosis pigmentovascularis type IIa successfully treated with two types of laser therapy.

We describe a 28-year-old Japanese woman with phacomatosis pigmentovascularis type IIa who was treated by 27 sessions of Q-switched ruby laser irradiation to the site of dermal melanosis on her face and three sessions of dye laser irradiation to the port-wine stain on her left cheek. This is the first report of the successful treatment of a cutaneous lesion in a patient with phacomatosis pigmentovascularis. As the outcome of the treatments was excellent, we conclude that phacomatosis pigmentovascularis type IIa can be treated successfully by the combination of the two types of laser therapy.

Laser resurfacing of the skin for the improvement of facial acne scarring: a systematic review of the evidence.

This review presents and evaluates the evidence of the effectiveness of laser resurfacing for facial acne scars. Primary studies of all types of design in any language were identified from MEDLINE, EMBASE, the Cochrane database, Science Citation Index and various internet sites. Studies were accepted if they included patients treated by any laser for atrophic or ice-pick acne scars. The quality of the studies was assessed and data extracted by two independent researchers. There were no controlled trials but 14 case series were found which reported the effects of either the carbon dioxide or erbium:YAG laser. All of the studies were of poor quality. The types and severity of scarring were poorly described and there was no standard scale used to measure scar improvement. There was no reliable or validated measure of patient satisfaction; most improvement was based on visual clinical judgement, in many cases without blinded assessment. The inaccurate use of ordinal scales meant that any improvement was impossible to quantify with any validity, although the evidence suggested that laser treatment had some efficacy (a range in individual patients of 25-90% for both the carbon dioxide laser and the erbium:YAG laser). Changes in pigmentation as a side-effect were common (in up to 44% of patients), although lasting only a few weeks. Laser resurfacing technology is increasingly used in clinical practice to treat acne scars. Despite the poor quality evidence, it is plausible that there is some improvement of acne scarring; there is insufficient information, however, for patients to make informed decisions on whether to opt for treatment and there is not enough evidence to compare the two types of laser. There is a particular lack of information about the psychological effects of acne scar improvement. Good quality randomized controlled trials are needed with standardized scarring scales and validated patient outcome measures in order to assess the effectiveness of laser resurfacing in this group of patients.
