[A new classification of photodermatoses].

The authors present a new classification for photodermatosis in five groups: 1. Primary toxic photodermatosis that means lesions produced in all human beings by non-ionized radiation. 2. Photodermatosis induced by drugs, with two subgroups--phototoxic and photoalergic--according to the mechanism of action of the drug. 3. Idiopathic photodermatosis in which the photonic effects are known but the chromophores are unknown; four conditions are included here polymorphous actinic eruption, solar urticaria, actinic reticuloid and hidroa vacciniforme. 4. Miscelanea group which includes several conditions of unknown mechanism which are not included in the other groups, such as: actinic cheilitis, actinic poikiloderma, actinic ceratoses, epitheliomas, melanomas and others. 5. Conditions precipitated or aggravated by solar radiation with two sub-groups: hereditary (xeroderma pigmentosum, Hartnup's syndrome and other) and acquired (lupus erythematosus, pellagra and other). In group 1, the authors propose the designation of actinic elastotic dermatosis to unify different conditions described by several authors such as: diffuse elastosis, citrein skin, cutis rhomboidalis, and others.

[Calcinosis of the scrotum].

A critical review of the present classification of the calcinosis cutis is done and the difficulties to make it more precise are pointed out: it is hard to put together diseases totally different that have in common only calcium deposits in the skin; there is a lot of confusion in the current terminology; some authors don't recognize certain entities and; in a few times their own definitions are not respected. A cause of scrotal calcinosis (SC) secondary to epidermoid cysts calcification is presented. The authors believe that many cases classified as idiopathic calcinosis of the scrotum can be in reality late stages of a dystrophic calcification. They suggest that serial cuts in the histopathology examination of every lesion of SC should be performed in order to establish the existence or not of any epithelial remnant. Considering the fact that the treatment is surgical and mostly due to esthetic reasons, they also suggest to follow, if possible, a significant number of patients from an early to a late stage of the disease; only in this way it will be possible to know about the natural history of the scrotal calcinosis.

[Transient acantholytic dermatosis. Presentation of a case].

A case of DAT is presented and the literature is reviewed. The authors verify the limitation of the present therapeutics and they discuss the possible pathogenic mechanism. They also say that "unspecific" lesions resistant to conventional therapy, and mostly localized in the trunk of middle-aged patients may suggest the diagnosis of DAT if biopsy is performed in these cases there probably will be a higher incidence of the disease. As far as we know this is the first brazilian case of DAT reported.

[Hypersensitivity syndrome caused by phenytoins and phenobarbital].

Recently we have seen three patients with a clinically characteristic hypersensitivity reaction to phenytoin two to four weeks after they started these therapy. The picture simulated a severe infectious exanthem; it was characterized by a generalized erythematous macular eruption, massive edema of the face, fever, generalized lymphadenopathy and hepatic involvement. The laboratory findings revealed leukocytosis with atypical lymphocytes, eosinophilia and altered liver function. Involution of the eruption was characterized by exfoliation similar to that observed in scarlet fever. There was prompt and good response to treatment with systemic steroids.
