[Acquired tufted angioma in an adult: failure of pulsed dye laser therapy].

BACKGROUND: Tufted angioma, described by Wilson Jones in 1976, is a benign acquired vascular tumor occurring in children or young adults, usually located on the neck or the upper part of the thorax. Pathology examination confirms the diagnosis showing well-limited lobules in the dermis composed of tight clusters of capillaries without atypical cells. CASE REPORT: An 81-year-old woman consulted for a large extensive angiomatous lesion involving the neck and shoulder which had developed over two years. Histopathology reported tufted angioma. Treatment with pulsed dye laser was unsuccessful. DISCUSSION: Different treatments have been proposed for tufted angiomas: surgery, cryotherapy, interferon, argon laser and pulsed dye laser. This is a second cases of unsuccessful treatment, perhaps due to deep extension of the angioma.

[Multiple congenital smooth-muscle hamartomas].

BACKGROUND: Smooth muscle hamartoma is an uncommon lesion. Diagnosis is usually made at birth in infants presenting a plaque with minimal or no infiltration and covered with long dark hairs. Congenital forms with multiple plaques are rarely reported. CASE REPORT: A 5-day-old infant (normal pregnancy and delivery) had plaques localized on the buttocks, the left thigh, leg and shoulder and the right ankle. The plaques were minimally infiltrative and covered with long black hairs. Histology examination showed hyperplastic smooth muscle bundles with varying orientation. The diagnosis was smooth muscle hamartoma. The rest of the clinical examination was normal. CONCLUSION: This case of congenital smooth muscle hamartoma showed a particular form with partially regressive multiple plaques.

[High resolution ultrasound imaging: value in treatment of basocellular carcinoma by cryosurgery].

OBJECTIVE: We conducted a prospective evaluation of the contribution of high-resolution ultrasound imaging prior to cryosurgery for basocellular carcinoma and in search for recurrence. PATIENTS AND METHODS: All patients seen between 1992 and 1994 at the skin tumor clinic and treated by cryosurgery were included. Ultrasound imaging using 20 MHz prototype was performed prior to cryosurgery and 2 months later. RESULTS: Among 101 patients treated, 112 basocellular carcinomas were treated by cryosurgery. Ultrasound imaging provided good visualization of the tumor limits in all cases. The ultrasound aspect was anechogenic, often with rare areas of highly dense echoes. The tumor limits described by ultrasound imaging were larger than the clinical limits in 32% of the cases. In 8 of the 16 cases of recurrent tumors, the ultrasound examination revealed the recurrence first. In the other 8 cases, clinical manifestations were confirmed by ultrasonography. In our series, recurrence of basocellular carcinoma was statistically more frequent when the depth of the tumor was 3 mm (ultrasonographic measurement) or when the lateral limits established by ultrasound assessment were greater than the clinical evaluation. DISCUSSION: These findings demonstrate that high-resolution ultrasound imaging of basocellular carcinomas prior to cryosurgery: 1) visualizes tumor limits allowing adapted cryosurgery, 2) identifies factors with predictive value for recurrence, 3) can identify recurrences early. Ultrasound imaging of the skin is a useful non-invasive technique for pre- and post-therapeutic assessment of skin tumors and could be a particularly useful tool for "blind" cryosurgery destruction of skin tumors.

[Chronic radiodermatitis after heart catheterization: the contributing role of ciprofibrate (Lipanor)?].

BACKGROUND: Radiodermatitis after cardiac catheterization procedures has been reported in only a few cases in the literature. This side effect may not however be uncommon after long or repeated endocavitary explorations. CASE REPORT: We observed a case of chronic radiodermatitis which developed after cardiac catheterization, in a patient treated with corticosteroids and ciprofibrate for lupus. The patient had undergone only one heart catheterization. A second catheterization performed when the patient had stopped ciprofibrate did not provoke new lesions. DISCUSSION: This observations would suggest that ciprofibrate could participate as a radiosensitizing factor in the development of radiodermatitis.
