A Case of Lower Extremity Lymphedema in an Endstage Cancer Patient Complicated by Persistent Lymphorrhea / 대한피부과학회지

Secondary lymphedema occurs when normal lymphatics suffer a significant insult such as cancer, radiation therapy, surgery, trauma, or infection. Recurrent infections such as cellulitis, lymphangitis, and cutaneous lymphorrhea are significant complications in lymphedematous sites. A 58-year-old man with endstage colon cancer was referred to our department with a skin lesion and persistent discharge on both legs. On histopathological examination, numerous dilated lymphatic channels which were D2-40 positive were seen in the dermis. Herein, we report an interesting case of lower extremity lymphedema in an endstage cancer patient complicated with persistent cutaneous lymphorrhea.

A Study of a Patient with a Subepidermal Calcified Nodule on the Sole / 대한피부과학회지

Subepidermal calcified nodule is a rare form of calcinosis cutis, which is not associated with any dermatologic or systemic diseases, and usually presents as a solitary hard nodule on the face or neck of children. A 25-month-old boy had a small pea-sized, tender nodule on his left sole that had been present for several months. There was no history of previous trauma or systemic illness. The clinical diagnosis as a viral wart was initially made and treated with cryotherapy. Because the lesion was not clear and a yellow-white firm papule was seen after cryotherapy, punch excision was done. Histologic examination showed cystic structure with calcium deposition in the upper dermis. Herein, we present the findings of a patient with a rare, solitary subepidermal calcified nodule on the sole.

Results of Using the Patch Test with Urushiol in Korea / 대한피부과학회지

BACKGROUND: Allergic contact dermatitis (ACD) due to urushiol is a relatively common phenomenon in Korea. However, there are no recent studies regarding the results of patch tests with urushiol in ACD patients. OBJECTIVE: The purpose of this study was to analyze the results of the urushiol patch test, and to compare current urushiol sensitivity with findings from previous reports. METHODS: Patch test with 0.002% urushiol allergen and a thin-layer rapid use epicutaneous (T.R.U.E.) patch test were performed in 200 patients (67 men and 133 women) who were suspected of having ACD, between July 2011 and July 2013. Patient demographic findings and patch test results were evaluated. RESULTS: Positive reactions to urushiol were observed in 23 patients (11.5%), with a mean age (+/-standard deviation) of 61.4+/-10.8 years, which was significantly older than the mean age of 47.6+/-16.4 years of patients testing negative for urushiol sensitivity (p<0.001). Patients aged 50~59 years had the highest incidence of a positive reaction, and this difference in urushiol sensitivity according to age groups was statistically significant (p<0.005). A total of 8 (11.9%) of the 67 male patients, and 15 (11.3%) of the 133 female patients showed a positive reaction to urushiol. Of the 23 patients with a positive reaction to urushiol, 19 patients (82.6%) had at least one positive reaction to the T.R.U.E. test allergen, with p-phenylenediamine showing the highest sensitization rates (31.6%). The most frequently affected site in urushiol-positive patients was the face (39.1%). CONCLUSION: Based on our study results, urushiol sensitivity among Korean ACD patients is a relatively common occurrence, and a patch test with urushiol would be helpful in identifying the causative allergen in ACD patients.

Two Cases of Post-piercing Auricular Perichondritis Caused by Pseudomonas aeruginosa / 대한피부과학회지

Piercing of various parts of the body is common practice in Korea nowadays. In particular, ear piercing appears to be increasingly prevalent among adolescents and young-adults. Because of the complication of the procedure, auricular perichondritis after piercings can arise in this patient population. Staphylococcus aureus and Pseudomonas aeruginosa are the most common causative organisms associated with infections due to ear piercing. In most cases, however, the patients were not prescribed anti-pseudomonal antimicrobial agent at presentation. This may result in persistent complicated infection and permanent cosmetic deformities. Herein, we describe two cases of post-piercing auricular perichondritis caused by P. aeruginosa successfully treated with intravenous antimicrobial agents. Also, a literature review of auricular perichondritis after ear piercing was done.

A Case of Atypical Cutaneous Tuberculid in an Immunocompromised Patient / 대한피부과학회지

Cutaneous tuberculids are relatively rare hypersensitivity reactions to Mycobacterium tuberculosis, characterized by erythematous eruption on the skin of a tuberculosis patient. Papulonecrotic tuberculid, lichen scrofulosorum, erythema induratum and nodular tuberculid were originally included in tuberculids. However, some cases are difficult to classify into the subtypes because of their broad spectrum of cutaneous manifestations and various histopathologies. This is particularly true in immunocompromised patients. We report a case of atypical cutaneous tuberculid in an immunocompromised patient in whom mycobacterical DNA was not demonstrated by PCR. However, the diagnosis of latent tuberculous infection was supported by IFN-gamma assay (QuantiFERON(R)-TB Gold test) and tuberculous lymphadenitis was diagnosed. The skin lesions responded dramatically to anti-tuberculous therapy, and there has been no evidence of recurrence.

A Case of Zosteriform Cutaneous Metastasis from Lung Cancer / 대한피부과학회지

Cutaneous metastasis is a relatively rare complication of internal malignancy and has been reported in 0.7% to 9% of all malignant cancers. It may be an important clue for undiagnosed malignancies or even the prognosis of primary cancers. Cutaneous metastatic cancers vary in type and are rarely presented with zosteriform distribution. The lung is one of the most common primary sites of zosteriform cutaneous metastasis. We describe a 52-year-old man with a prior history of lung cancer in whom zosteriform cutaneous metastasis developed along the right T4-5 dermatome on his trunk. This case highlights the importance of the differential diagnosis of cutaneous metastasis with zosteriform distribution and the need of skin biopsy in order to confirm the early diagnosis.

A Case of Solitary Molluscum Contagiosum Occuring on the Sole of a Healthy Adult / 대한피부과학회지

Molluscum contagiosum is a viral infection of the skin and mucous membranes which is caused by a DNA virus from the poxvirus family. It is usually transmitted by direct skin contact, autoinoculation or fomites. Children are generally affected, and adults who are immunocompromised or sexually active may also be afflicted. Although molluscum lesions can be presented on any skin surface of the body, its occurrence on the sole is unusual. Molluscum contagiosum virus appears to have a particular affinity for follicular epithethelium and it may explain its lack of sole involvement. A 30-year-old male had a small pea sized nodule on his right sole that had been present for several days. Histological examination showed numerous molluscum bodies within the epithelium. Herein, we report a rare case of solitary molluscum contagiosum on the right sole of a healthy male patient.

Cutaneous Lymphoid Hyperplasia Which Developed after Allergy Skin Test of Antibiotics / 대한피부과학회지

Cutaneous lymphoid hyperplasia (CLH, pseudolymphoma) refers to a heterogeneous group of benign reactive T- and/or B-cell lymphoproliferative diseases of the skin, that resemble cutaneous lymphoma both clinically and histologically. Despite the unknown causes of CLH development, various stimuli can induce CLH, such as medications, infections, insect bites, photosensitivity and foreign agents. To date, there has been no reported case of CLH development after an allergy skin test of antibiotics. Thus, we report a patient who developed CLH following an allergy skin test of antibiotics. He was a 21-year-old man who presented with 1.5x1.5 cm sized erythematous plaque with yellowish crusts on his right forearm that showed features of a CLH, based on histopathologic assessment.

A Case of Motor Paralysis of the Limb Caused by Herpes Zoster / 대한피부과학회지

Herpes zoster is a common viral disease that accompanies segmental, painful vesicular eruptions along the dermatome. Motor involvement can also occasionally occur in this disease entity and its reported incidence is between 0.5% and 5%. However, the impairment of motor function often goes unrecognized, probably because of severe pain that is a more prominent feature than motor weakness. We experienced an 83-year-old female patient with herpes zoster infection of the right C5-7 dermatomes, who showed right upper extremity paralysis. We examined the limb using motor nerve conduction velocity (MNCV) test and concluded that herpes zoster caused patient's motor paralysis. After 4 months, her motor paralysis was completely recovered spontaneously.

Multiple Lichen Striatus in an Adult / 대한피부과학회지

Lichen striatus is an uncommon, self-limiting dermatosis that is characterized by linearly distributed eruptions that follow Blaschko's lines. It usually occurs unilaterally, but few cases of bilateral or multilinear eruptions have also been reported. In addition, lichenstriatus is commonly seen in children and rarely affects adults. We report a case of 29-year-old woman with multiple, unilateral lichen striatus on the right abdomen and right chest that was treated successfully with topical tacrolimus.

Tinea Capitis Caused by Trichophyton rubrum in an Adult Woman Judoist / 대한의진균학회지

Tinea capitis occurs mostly in the children and rarely affects adults. The most common cause of tinea capitis is known as Microsporum canis. Trichophyton rubrum is an anthropophilic, commonest dermatophyte affecting man but rarely involves the scalp and hair. A 19-year-old woman, current judo player, presented with 1-month history of hair loss and erythematous scaly macules with brownish crusts on her scalp. The patient was diagnosed as tinea capitis caused by T. rubrum based on macroscopic and microscopic characteristics of the fungus culture. As T. rubrum rarely causes tinea capitis, we assumed this patient might have had contact with T. rubrum on the ground or other players while playing judo, which could be described as tinea gladiatorum.

Postoperative stability and occlusal plane alternation by orthgnathic surgery of skeletal Class III malocclusion with anterior open bite / 대한치과교정학회지

The purpose of this study is to investigate the stability of counterclockwise rotation of mandible by sagittal split ramus osteotomy to correct the skeletal Class III malocclusion with anterior open bite. Twenty five skeletal Class III open bite patients(mean age 20.6 years) who were treated by the sagittal split ramus osteotomies with rigid fixation were examined in this study. Cephalometric radiographs were taken for ach patients preoperative(T1), early postoperative(T2), and late postoperative period(T3). Mean postoperative period(T3).Mean postoperative period was 8.0 months. Cephalomerric analysis was done and data from T1, T2, and T3 were analyzed statistically by paired t-test and pearson correlation analysis. The following results were obtained. 1. Mandibular plane angle decreased 2.9degrees and mandibular occlusal plane angle related to SN plane decreased 2.7degrees after orthognathic surgery(T2). At 6 months after orthgnathic surgery(T3), mandibular plane angle increased 1.0degrees, but mandibular occlusal plane angle did not changed. 2. The amount of horizontal relapse long time after orthornathic surgery(T3) was 1.6mm at B point and it was 22% of the total posterior movements. There was no vertical relapse in the anterior facial height. 3. The related factor with horizontal relapse at late postoperative period was mandibular plane angle(p<0.01). The related factors with decreasing posterior facial height were amount of mandibular setback(p<0.01), increasing of mandibular ramus height(p<0.01), and decrease of the mandibular plane angle during operation(p<.01). 4. There was no relationship between the amount of changes in mandibular occlusal plan angle during operation and the amount of relaspe after surgery.

Three dimensional finite element analysis of the phenomenon during distal en masse movement of the maxillary dentition / 대한치과교정학회지

This study was designed to analysis the displacement and stress distribution of individual tooth by orthodontic force during distal en masse movement of the maxillary dentition. In this study, three dimensional finite element analysis was used. Author made the finite element model of maxillary teeth, periodontal ligament, alveolar bone and bracket with anatomic and physiologic characteristics on computer. Author analysed and evaluated the displacement and stress distribution of individual tooth when extraoral force, Class II intermaxillary elastics, ideal arch wire, MEAW and tip back bend were used for distal en masse movement of the maxillary dentition. These analyses were also applied in the case of the maxillary second molar were not extracted. Author compared the results of the cases which maxillary second molar were extracted or not. The results were expressed quantitatively and visually. Author obtained following results, 1. When anterior headgear was applied, the posterior translation, posterior tipping, and vertical displacement of teeth were produced more in the anterior segment of the dentition. 2. When Class II intermaxillary elastics were applied in the ideal arch wire, the teeth disp acement were usually produced in the anterior segment. But when tip back bend were added in the ideal arch, the orthodontic force produced by elastics were transmitted to the posterior segment. As increasing the tip back bend, posterior translation and lingual tipping of anterior teeth were decreased, posterior translation and tipping displacement of posterior teeth were increased, and extrusion of anterior teeth by Class II elastics were decreased. 3. When MEAW and Class II elastics were applied, the teeth movement were similar with the case of ideal arch wire and Class II elastics, but more small and uniform teeth displacement were produced. Compared with the ideal arch wire, posterior tipping of the posterior segment were more produced than lingual tipping displacement of the anterior segment. 4. When the maxillary second molar without orthodontic appliance existed, the displacement of maxillary first molar were decreased.

The morphologic characteristics of Class I, non-extraction patients / 대한치과교정학회지

The purpose of this study was to investigate the pretreatment and posttreatment dentofabial characteristics of non-extraction patients with Class I malocclusion. And to compare this result with matched non-orthodontic normal occlusion and Class I premolar extraction patients. Such comparison might help identify morphologic characteristics of the non-extraction patients. Initial and final cephalometric evaluation were compared in a sample of 22 patients with Class I malocclusions treated in non-extraction manner with edgewise appliance and MEAW. The mean age of the total population was 14 years 9 months and the average treatment time was 2 years 8 months. 32 landmarks were located and digitized on each cephalogram. From these landmarks, 24 linear and angular dimension were obtained Student's t-test were used to compare the pretreatment - posttreatment results, Nonextraction - Normal groups, and nonextraction - Extraction groups. Significance was predetermined at p < or = 0.05. The results were gas follows. 1. Before treatment, the mean value of the ODI was 69.9degrees, APDI was 82.1degrees, CF was 152degrees, and El was 152degrees in the non-extraction groups. 2. The skeletal pattern of the non-extraction groups were similar with non-orthodontic normal group3, but the non-extraction groups had larger interincisal angle. 3. Comparison between groups treated with and without extraction indicated at pretreatment, the extraction groups had more protrusive lips, smaller interincisal angle, and El. 4. After treatment, there was no significant changes in the skeletal pattern of the non-extraction groups, but uprighting of the maxillary and mandibular first molar and decrease of the interincisal angle were seen.

A roentgenographic study on the extraction index in Korean adolescent / 대한치과교정학회지

To extract or not to extract permanent teeth for the correction of malocclusion has been a great debate in the history of orthodontics, and there is a variety of analytic methods and criteria to aid in the diagnosis. Extraction formulas that has been presented are many analytic methods that depend on arch length discrepancy, dental prominence, and skeletal pattern of the each patients. Of these analysis, the most important diagnostic factor is patient's skeletal pattern. Because the behavior of the dentition is closely dependent upon the skeletal pattern of each patient, dentition must be arranged within that person's skeletal frame. El(Extraction Index) is composed of CF, interincisal angle, and lip position, CF is made of ODI and APDI that differentiate vertical and horizontal component of the skeletal pattern. So, EI not only represents patient's skeletal pattern, but also takes facial appearance into consideration, This study was undertaken to investigate EI and related cephalometric variables on the cephalogram of Korean adolescents which consisted of 153 persons with normal occlusion, harmonious skeleton and pleasing face. The following conclusions were obtained. 1. The mean value of the ODI is 73.5degrees, APDI 82.5degrees, CF 156.3degrees 2. The mean value of the interincisal angle is 123.6 degrees. 3. The mean distance of upper lip to E-line is 0.0mm, lower lip to E-line is 1.4mm. 4. The mean value of the EI is 153.8degrees.
