[Paraneoplastic digital necrosis: a case report]. / Necrose digitale paraneoplasique: A propos d'une observation.

BACKGROUND: Digital necrosis is a frequent vascular disease. Its very often reflects arterial disorders of macro or mirocirculation. Paraneoplastic digital necrosis is rare, however. AIM: Report a new case of paraneoplastic digital necrosis CASE: 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. CONCLUSION: 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.

[Cryosurgery for nose basal cell carcinoma. Series of 17 tumors]. / Place de la cryochirurgie dans le traitement des carcinomes basocellulaires du nez. A propos d'une série de 17 tumeurs.

UNLABELLED: Basal cell carcinoma (BCC) is the most common malignant tumour of the skin frequently located on the head and chiefly on the nose. Cryosurgery is one of the methods to treat BCC. OBJECT: To determine the efficacy of cryosurgery of 17 BCC of the nose in terms of recurrence rates and cosmetic results. RESULTS: 15 patients were included with a median age of 73 years and a photo type III or IV in 86% of cases. Mean size of tumours was 12 mm. Lesions were chiefly located on the alae nasi (70.5%). Complications were few and minor. After an average follow-up of 13.5 months, recurrence rate was about 5.8% (one case). Cosmetic results were good or excellent in 14 cases/17; only one patient had developed a notch of the nose. CONCLUSION: Cryosurgery is a rapid, of a low cost technique and chiefly with good oncological and cosmetic results.

[Necrobiosis lipoidica. Report of 4 cases and review of the literature]. / La necrobiose lipoidique. Etude de 4 cas et revue de la littérature.

Necrobiosis lipoidica belongs to the inflammatory granulomatous skin disorders groups with palisade reaction. The association to diabetes mellitus is classical involving 80% of diabetics in its tibial localization. A retrospective study of all cases of necrobiosis lipoidica conducted in our dermatology department over a-15-year period, found 4 diabetic patients, 3 of whom were women known as diabetic patient with extremities involvement, and 1 man not known as diabetic patient at the time of the diagnosis. Necrobiosis lipoidica appears to be a rare disorder in diabetic people and this association seems to be over estimated.
