    ABSTRACT: Punctate palmoplantar keratoderma (PPPK), or Buschke-Fischer-Brauer's disease, is a rare form of genodermatosis with autosomal dominant transmission and with variable penetrance. Its molecular basis remains unknown. Two loci were found to be linked to this disease: one on 15q22 and the other on 8q24. We report the clinical and genetic characteristics of PPPK in a Tunisian family. A Tunisian family with PPPK was identified through a proband. As far as possible, history taking, physical examination, histopathological tests and blood sampling for DNA extraction were carried out for each patient. Seventeen patients were included in this study. Age ranged from 15 to 81 years with a sex-ratio of 3.2 m/f. Lesions appeared between the ages of 10 and 65 years and at a mean of 28 years. Clinically, lesions ranged from few keratotic papules on the palms to coalescence of lesions in plaques over palmar and/or plantar surfaces. Hyperhydrosis, hypopigmented macules and nail dystrophy were frequently associated. In all patients, histopathological examination revealed thickening of the epidermis with compact orthohyperkeratosis overlying a small and sharply demarcated area of depressed epidermis. Mechanical measures and keratolytic ointments proved non-beneficial. Genotyping for chromosomes 8 and 15 as well as LOD scores confirmed genetic linkage with the suspected locus on chromosome 15q, with the interval of the locus in question reduced to 3.26 Mb. This region is flanked by markers D15S987 and D15S153. Our study of this family confirmed the classical characteristics of KPP-BFB as well as demonstrating several associated clinical signs of which the significance will be determined in subsequent studies. Further screening studies to identify mutated genes in the region of interest will help us to understand the molecular basis of this disease and hopefully to propose suitable treatment.

    ABSTRACT: Granuloma multiforme is a rare granulomatous skin disease, usually reported in sub-Saharan African countries. The exact aetiology of granuloma multiforme is still unknown. We report the case of a patient who presented clinical and histopathological features of granuloma multiforme that can be considered the first described case in Tunisia.
