A case of non-familial multiple digitate hyperkeratosis is reported. Digitate hyperkeratosis is a new, non-follicular disorder of keratinization and three different types have been distinguished in the literature: the familial type, with an autosomal dominant trait; the sporadic type; and the post-inflammatory type.
The association between livedo reticularis and cerebrovascular accidents is known as Sneddon's syndrome. We describe a case in which Sneddon's syndrome appeared as a clinical manifestation of primary antiphospholipid syndrome.
The effects of prednisone, oral acyclovir, and radiotherapy were compared with placebo in the prevention of post-herpetic neuralgia. No treatment used was able to prevent, with statistical significance, post-herpetic neuralgia, although prednisone and acyclovir showed some pain reduction in the acute phase. Radiotherapy was of no value in either the acute or post-herpetic phase.
The second known case of a skin infection caused by Botryomyces caespitosus is reported. This case has made it possible to describe the characteristics of this fungus in vivo and to establish it as another agent of phaeohyphomycosis.
A case of linear IgA disease is presented. In association with typical cutaneous lesions and linear IgA deposits along the basal membrane, the Authors describe the severe ocular involvement with blindness of the right eye. The Authors also underline palmar involvement with hyperkeratosis and scleroderma-like aspect.

A case of paracoccidioidomycosis, previously treated for tuberculosis for two years, is reported. Combined treatment with oral ketoconazole and sulfamethoxypyridazine was successful. The problem of a low index of suspicion among physicians for tropical mycoses, which are very rarely observed in Italy, is discussed.
To assess the presence of Chlamydia trachomatis in nonacute abacterial prostatitis 30 patients with urethral cultures positive for Chlamydia trachomatis underwent microbiological studies, including cultures of transrectal aspiration biopsies of the prostate. Chlamydia trachomatis was isolated from 10 of the prostatic specimens (33 per cent). In 3 cases a nonspecific cytopathogenic effect caused the destruction of the tissue cultures. Our findings demonstrate that Chlamydia trachomatis may cause ascending infections of the prostate and that this microorganism may have an etiological role in the pathogenesis of nonacute abacterial prostatitis.
Multiple keratoacanthomas (KAs) of the Ferguson-Smith type represent a rare and distinctive disease for which treatment is difficult and often unrewarding. Two patients with multiple KAs of this variety, who were successfully treated with oral etretinate, are described. Our cases support the conclusion that oral retinoids have to be added to the treatment modalities for this entity. Use of oral retinoids is particularly recommended when the number of lesions is very high or when the development of new lesions is severely disabling.
Cutaneous manifestations in a case of Reiter's disease were successfully treated by oral etretinate administration. The clinical and histopathological similarities between the skin lesions of Reiter's disease and those of pustular psoriasis, which is known to respond to aromatic retinoids, suggested this treatment.
A case of sacral herpes zoster associated with alteration of urination and defecation is presented. The pathogenetic mechanisms of these unusual complications are discussed.

White sponge nevus is a rare, benign, inherited disorder of the mucous membranes, affecting mainly the oral mucosa. A case is reported of white sponge nevus, which showed a definite improvement following penicillin administration.
A patient affected by rheumatoid arthritis developed pemphigus erythematosus after 14 months of treatment with thiopronine. The lesions healed spontaneously after 4 weeks' withdrawal of the drug. Whereas the pemphigus erythematosus induced by D-penicillamine is a quite rare but well documented side effect, we believe our case to be the first one reported as being due to thiopronine. It is very interesting to note that the two drugs are very similar with regard to chemical structure, mechanism of action, therapeutic indications and also side effects.
