BITTENCOURT, Achiléa L and OLIVEIRA, Maria de Fátima. Infective dermatitis associated with the HTLV-I (IDH) in children and adults. An. Bras. Dermatol. [online]. 2005, vol.80, suppl.3, pp. S364-S369. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962005001000017.
Infectious dermatitis associated with HTLV-I (IDH) is a form of infected and recurrent dermatitis which affects children vertically infected with HTLV-I. IDH starts after 18 months of age. The lesions are erythematous-scaly and frequently crusty and are more frequently located on the scalp and on the retroauricular regions, but the lesions may be generalized. Pustules, erythematous-scaly and follicular papulae and retroauricular fissures may also be observed. Children present mild to moderate pruritus, lesions in the nostrils, and blepharoconjunctivitis. IDH is always associated with Staphylococcus aureus infection and/or Streptococcus beta haemolyticus infection. The differential diagnosis with atopic and seborrheic dermatitis can be made clinically. Histologically it is important to make a differential diagnosis with psoriasis and cutaneous T-cell lymphoma. We discuss here the clinical-immuno-pathological aspects, the differential diagnosis, and the evolution of IDH. Considering the frequency of IDH in Salvador, Bahia, we suggest that children with severe eczema be submitted to routine serology for HTLV-I and that IDH be included in the differential diagnosis of dermatitis in adulthood.
