Trichost.asis Spinulosa consists of several fasciles of reta ned vellus hairs in the hyperkeratotic sebaceous follicles, resulting in a dark slightly raied horny follicular spines, resembling comedones on the trunk and face. The condition is relatively common, particulary among the age, but is usually overlooked on routine skin examination as the patient is rarely aware of it.. We report 6 cases of trichostasis spinulosa, which showed numerous asymptomatic tiny black comedo-like dots on their backs. We obtained the follicular material by tweezer, which consised of several vellus hairs surrounded by a keratinous plug. Histologic examination was done in 3 patients, one of whom showed a rarely reproted double follicle and double papilla. With scanning electron microscopy, we observed multiple vellu hairs embedded in a keratotic plug, emerging from a hair follicle opening.

Two avulsed ears attached by very narrow subcutaneous pedicles were repaired with only cutaneous sutures and showed complete survival. The results showed that the entire auricle could be fully vascularized by just a single small vascular branch. This clinical result is compatible with our previous findings in anatomical study concerning arterial supply of the auricle.

PURPOSE: To evaluate the findings and the role of CT in plexiform neuro-fibromatosis of the mediastinum. MATERIALS AND METHODS: We retropectively reviewed the CT scans of five patients with plexiform neurofibromatosis of the mediastinum. The CT scans were reviewed with attention to the distribution of the lesions, appearance and attenuation of mediastinal lesions, enhancement pattern after intravenous contrast infusion and associated findingssuch as intercostal neurofibroma. RESULTS: In all five patients CT scans demonstrated fusiform low attenuated masses which were oriented longitudinally and extended over multiple contiguous scans along the distribution of major mediastinal nerves. In four patients, mediastinal lesions appeared infiltrative, obliterating adjacent mediastinal fat plane. One patient had well defined fusiform masses along the major mediastinal nerves. Postcontrast enhanced CT scans revealed slight central enhancement in two patient and no contrast enhancement in three patients. Associated findings such as neurofibromas of intercostal nerves and sympathetic trunk, or subcutaneous neurofibromas were detected on CTscans in all five patients. CONCLUSION: Characteristic CT findings of low attenuation masses along the major mediastinal nerves are helpful to differentiate plexiform neurofibromatosis from mediastinal lymphadenopathy and to prevent from misreading as a malignant disease.

The real time high resolution mechanical neurosonographic sector scanner is a convenient and useful instrumentfor detection of intracranial lesions in premature infants as well as low birth weight. From this experience,authors report with 104 neonates and infants who had been suspected intracranial hemorrhage and had been detectedand graded by sonography. The results were as followed: 1. The incidence of intracranial hemorrhage is 20 of 46(43.5%) neonates who had been studied before 3 days of age. But 7 of 16(43.7%) neonates showed ICH between the 4-7days of age. 2. There was no difference of prevalence in sex ratio in neonates with ICH. 3. There was closerelationship between ICH and gestational weeks. 15 of 27 (55.6%) neonates who were born under 32 gestational weeksshowed ICH was graded as 3 or 4 in 7 of 10. 4. 10 of 16(62.5%) neonate who were born under 1,500 gram body weighthad ICH within first 4 days. The severity of ICH was graded as 3 or 4 in 7 of 10. 5. The mode of deliveryinfluenced neonatal ICH incase of difficulty delivery such as forcep(4/4, 100%), vacuum (7/10, 70%), breech (3/3,100%), and C/S(13/33, 39.4%). 6. Incidence of ICH in neonates with pathologica lung conditions (29/40, 72.5%) washigher than ICH with normal chest findins(15/64, 23.4%). 7. For frequent follow up study of brain, neurosonographywas very helpul and economic in case of ICH, and could find congenital glioblastoma multiformed(1), and low gradeastrocytoma(1) incidentally.
