Paraneoplastic digital necrosis: a case report

Digital necrosis is a frequent vascular disease. Its very often reflects arterial disorders of macro or mirocirculation. Paraneoplastic digital necrosis is rare, however.Report a new case of paraneoplastic digital necrosis. Our patient was a 62-year old diabetic female patient with a history of total thyroid ablation at 50 year old. She presented with bilateral digital necrosis of the second, third and fourth fingers. During her recovery, we have found a biological inflammatory syndrome and abdominal echography revealed a metastatic liver. Radiological investigations in search for the primitive tumour were negative. The patient was referred to a specialized center for a palliative chemotherapy. Etiologies of digital necrosis are various, mainly iatrogen, professional, toxic, atheroma or systemic disease. In case of no evident cause, explorations should be gone to detect underlying malignancies

Lichen sclereux genital

Lichen sclerosis is a chronic inflammatory mucocutaneous, disease which origin remains unknown. Its prevalence ranges from one in 300 to one in 1000 of all patients referred to a dermatology clinic in the seventeeth. Through the analysis of a hospital survey, we outline the epidemio-clinical aspects of this dermatosis. Over a 19-year period [1984-2002], we have conducted a retrospective and monocentric study of all patients with genital lichen sclerosis were examined at the dermatology department of Habib Thameur hospital. Thirty-four patients suffered from lichen sclerosis. There were 33 female and only one male [sex-ratio: 0.03]. All patients underwent topical corticosteroid therapy [level I, II or IV]. The recovery rate of lichen sc1erosus was about 20% [7/34]. An epidermoid carcinoma occurred in three patients. The frequency of lichen sc1erosus in our study is estimated at 1,8 new cases per year. This frequency is probably under-estimated because of some patients' reluctance to seek help. A relatively low recovery rate of genital lichen sclerosis was found in our study. This may be related to an inadequate follow up added to an insufficient treatment adherence

[Childhood linear psoriasis]

Linear distribution of psoriasis is rare. This presentation offers to physicians some diagnostic difficulty, especially in the absence of a history of preexisiting psoriasis or in the presence of any other linear dermatosis. In the study we report the cases of 3 girls aged repectively 45 yr and 10 yr admitted in our dermatology department. The clinical features and differential diagnosis of this skin disease which, in the children, can be easily mistaken for inflammatory verrucous epidermal nevus, are discressed
