RESUMEN
BACKGROUND: Dyeing is an age-old process and forms an integral part of textile industries. Tying is a process by which a particular part of cloth is prevented from the process of dyeing. The skin diseases in workers engaged in the 'tie and dye' industry have not been extensively studied. AIMS: To study the prevalence of contact dermatitis among workers engaged in the 'tie and dye' industries in and around Jodhpur (Western Rajasthan). METHODS: One thousand three hundred workers engaged in 'tie and dye' work were evaluated for occupation-related dermatitis. Those with skin lesions were subjected to patch tests using 2% aqueous solution of the dyes and chemicals commonly used by them. These included direct dyes, VAT dyes, sulfur dyes and azo dyes. Fifty workers without skin lesions served as controls. RESULTS: One hundred patients (7.69%) had dermatitis involving the exposed sites, mainly the hands and forearms. Eighty-one patients showed positive reactions to one or more dyes, most commonly Red RC base (azo dye), followed by naphthol. CONCLUSION: Red RC base and naphthol were the commonest allergens in the 'tie and dye' industry.

Various paraneoplastic dermatoses may be seen in association with underlying visceral, especially gastrointestinal, malignancy. Florid cutaneous papillomatosis describes the sudden appearance of multiple acuminate keratotic papules that morphologically resemble viral warts. It may be seen in association with acanthosis nigricans and/or the sign of Leser Triotalat. We report a 35-year-old male with extensive seborrhoeic keratoses and florid cutaneous papillomatosis. Unusually marked verrucous changes caused disfigurement of the hands and feet. The patient also reported dyspepsia, abdominal distention and weight loss 6 months prior to the development of cutaneous lesions. Gastroscopy revealed a large growth in the stomach. Histopathology of the tumor showed features of adenocarcinoma.

Juvenile hyaline fibromatosis (JHF) is a rare, autosomal recessively inherited disorder. We report two siblings with multiple large tumors on the scalp, translucent papules on the nape of the neck, hypertrophic gingiva, and severe flexural contractures of large joints. The histopathology from the skin lesions showed features characteristic of juvenile hyaline fibromatosis. The cases are being reported on account of the extreme rarity of the condition.
