The anatomical structure of vermiform appendix was studied for 124 Korean adult cadavers and the articles were reviewed with special reference to its position and length. The results are as follows ; 1. On the frequency of positional types based on Wakeley (1933), postileal type was recorded most frequently (37.7%) and retrocecal type was found in 19.7% of cases, showing the difference from other ethnic groups whose most frequent position was retrocecal or pelvic type. 2. In the direction of appendix in relation to the clock, the direction between 1 and 3 o'clock was most frequently found. 3. Appendix of fixed form was found in 22.1% of cases, that of free form 77.9%. In free form, postileal type was found most frequently, but retrocecal type was met most frequently in fixed form. 4. The length of appendix was 5.95±1.64 cm (male ; 6.14±1.67 cm ; female 5.59±1.51 cm). Neither significant difference between sex nor positional type was noted. 5. Positions of appendix are seemed to be set up during fetal stage. The Ethnic variation in the positions of appendix is thought to be determined by inherited physical anthropological factor, not by postnatal one.

Angioma serpiginosum is a rare acquired naevoid disorder, characterized by minute red or purple punta that are frequently arranged in serpiginous patterns in the lower extremities and buttocks. It usually begins in childhood and is more common in females. Histopathologically, thin-walled capillaries in the dermal papillae and the superficial reticular dermis are widely dilated without extravasation of red blood cells. We report a case of angioma serpiginosum on the lateral aspect of the right arm along the lines of Blaschko in a 36-year-old woman.

BACKGROUND: Drug reactions are common problems in hospital inpatients and outpatients. Reliable diagnosis is essential but often difficult. OBJECTIVE: This study attempts to define the clinical features and causative drugs in the patients with drug eruptions, and to evaluate the diagnostic value of skin tests. METHODS: Sixty one patients with drug eruptions were reviewed clinically. In 18 patients, patch and prick tests were performed using suspected drugs. RESULTS: 1. The highest incidence of drug eruptions was observed in the third and forth decades(44.2%) and there was no sexual prodominence. 2. The most frequent latent peroid was 4 hours to 1 week(49.2%). 3. The common morphological features were exanthematous eruptions(57.3%), urticaria(14.8%) and fixed drug eruptoins(11.5%). 4. The major causative drugs were antibiotics(cephalosporin, ampicillin), antipyretics/anti-inflammatory analgesics(aspirin, piroxicam) and CNS depressants(diphenylhydantoin). 5. Clinical manifestations according to possible causative drugs were as follows; exanthematous eruptions by antibiotics, antipyretics/analgesics, herbs, CNS depressants, propylthiouracil and captopril; urticaria by antibiotics and herbs; fixed drug eruption by sulfonamide, antipyretics/analgesics and phenobarbital; acneiform eruptions by diphenylhydantoin and isoniazid; Stevens-Johnson syndrome by ampicillin, sulfonamide, aspirin and piroxicam, erythema nodosum by sulfonamide, and lichenoid drug eruptions by propylthiouracil. 6. Positivity to patch and prick tests was shown in 2 of the 18 patients and in 1 of 18 patients, respectively. CONCLUSIONS: The most frequent clinical feature of the drug eruptions were exanthematous in nature and the most common causative drugs were antibiotics, as suspected. To search for the causative drug of the drug eruption, the only usual methods of patch and prick tests were not sufficient in our study.
