RESUMEN
To examine the prevalence of itching in psoriatic skin lesions and its relation with different variables. A simple questionnaire and a verbal four point intensity scale were used. Severity of disease was calculated by using Psoriasis Area Severity Index [PASI]. Six hundred and fourteen patients of psoriasis were examined in which majority were chronic plaque type. Pruritus was present in 79% of the patients, and was severe in 34%; moderate in 15% and mild in 29%. Pruritus was common in chronic plaque psoriasis. It was more severe in more severe type of psoriasis and was more common in females in comparison to males. But there is no difference between pediatric and adult psoriasis.
RESUMEN
Arsenicosis is a multisystem disorder, with many cutaneous features. The cutaneous manifestations take the form of pigmentary changes, hyperkeratosis, and skin cancers [Bowen's disease, squamous cell carcinoma, and basal cell carcinoma]. It is a known carcinogen and there is association between chronic arsenic exposure and malignancy of bladder, lung, liver, kidney and other visceral malignancies. Our patient came from an endemic area where levels of arsenic are high in drinking water and had features of arsenical keratosis for past fifteen years along with metastatic testicular cancer at the time of presentation. Arsenic exposure may increase the risk of testicular cancer
