Phytophotodermatitis is a condition caused by sequential exposure to photosensitizing substances present in plants followed by ultraviolet light. Several plants (e.g., limes, celery, fig, and wild parsnip) contain furocoumarin compounds (psoralens). It is important for dermatologists to be aware of phytophotodermatitis because it may be misdiagnosed as cellulitis, tinea, or allergic contact dermatitis. We present five patients with a sharply defined erythematous swollen patch with bullae on both feet. They described soaking their feet in a fig leaves decoction to treat their underlying dermatologic diseases. Within 24 hours, all patients had a burning sensation in their feet, and erythema and edema had developed on the feet dorsa with exception of the portion of the skin covered by the sandals. Histopathologic examinations revealed sub-epithelial blisters with intensive epidermal necrosis. Phytophotodermatitis was ultimately diagnosed and, after several days, the patients' skin lesions began to recover upon treatment with systemic and topical corticosteroids. Unfortunately, since there are no studies providing sufficient evidence on the benefits of fig leaves, they should be used with caution.

Detailed observations with dermoscopy can provide first clues of the presence of ABTM and underlying chronic liver disease.

BackgroundPsoriatic arthritis (PsA) is chronic seronegative inflammatory arthritis that causes irreversible joint damage. Early recognition of PsA in patients with psoriasis is important for preventing physical disability and deformity. However, diagnosing PsA in a busy dermatology outpatient clinic can be difficult.ObjectiveThis study aimed to validate the Psoriatic Arthritis Screening and Evaluation (PASE) questionnaire for the detection of PsA in Korean patients with psoriasis.MethodsThe PASE questionnaire was prospectively given to 148 patients diagnosed with psoriasis but without a previous diagnosis of PsA. All patients underwent radiologic and laboratory examinations, and a subsequent clinical evaluation by a rheumatologist.ResultsEighteen psoriasis patients (12.2%) were diagnosed with PsA according to the Classification Criteria for Psoriatic Arthritis. The PASE questionnaire scores of differed significantly between PsA and non-PsA patients. Receiver operator characteristic analysis showed an area under the curve of 0.82 (95% confidence interval: 0.72, 0.92) for PASE score. A PASE score cut-off of 37 points had a sensitivity of 77.8% and specificity of 82.3% for the diagnosis of PsA.ConclusionThe PASE questionnaire is a simple and convenient screening tool for detecting PsA in Korean dermatology clinics. A PASE questionnaire score of 37 points appears to be an appropriate cut-off for screening Korean psoriasis patients.
