Basal cell nevus syndrome with excessive basal cell carcinomas

Basal cell nevus syndrome (BCNS), also known as basal cell carcinoma nevus syndrome, Gorlin syndrome, Gorlin-Goltz syndrome, and nevoid basal cell carcinoma, is a rare autosomal dominant disorder with a prevalence of approximately 1/60,000. A lower prevalence rate of 1/13,939,393 has also been reported in Korea. We report the case of a 40-year-old male patient with multiple black pigmented macules on the face that first appeared when he was a teenager. His clinical features of jaw cysts, bifid ribs, and calcification of the falx cerebri were fitting within the criteria for the diagnosis of BCNS. We excised all suspected macules and sent permanent biopsy. Most of the histological examinations of the biopsy samples taken during surgical excision of the face masses showed basal cell carcinomas. Ten months after the surgery, the patient has remained free from symptoms and is undergoing follow-up observation.

Epidermoid cyst: A single-center review of 432 cases

Background@#Epidermoid cysts are benign tumors derived from the infundibular portion of hair follicles and thus have a flattened surface epithelium and keratohyaline granules. They can occur at any age but are most frequently reported in adults, and more often occur in men than women. Most epidermoid cyst operations are performed for cosmetic purposes, or to relieve inflammation. The definitive treatment is complete excision or destruction of the cyst. The aim of this study was to improve understanding of epidermoid cysts. @*Methods@#We analyzed 432 cases of epidermoid cyst in 398 patients that underwent complete excision and biopsy between April 2001 and March 2020, according to patient age, patient gender, and lesion location. @*Results@#From all epidermoid cyst excisions performed, 17.6% were for patients in their 40s and 50s, 16.8% for those in their 20s, 16.1% for those in their 30s, 14.6% for those aged 60 or older, 5.0% for teenagers, and 0.5% for those under 10 years. Cases of epidermoid cysts occurred at a men-to-women ratio of about 3:2, with 59.5% of cases in men and 40.5% in women. By lesion location, 65.0% of cases were on the face, 10.9% on the trunk, 7.9% on the scalp, 7.9% on the neck, 4.3% on lower extremities, 3.9% on upper extremities, and 0.2% on genitalia. On the face, 20.8% of cases were on the cheek, 12.7% on the periauricular area, 10.9% on the periorbital area, 6.0% on the frontal area, 5.6% on the mental area, 3.7% on the perioral area, 2.8% on the nasal area, and 2.5% on the temporal area. @*Conclusion@#The proportion of women with epidermoid cysts was higher in our study than in previous studies. Moreover, the results showed that surgery has been on the rise in recent years, with facial surgery being the most common.

Mucosa-associated lymphoid tissue lymphoma on right lower eyelid previously diagnosed as lymphoid hyperplasia

Mucosa-associated lymphoid tissue (MALT) lymphoma is an uncommon form of non-Hodgkin lymphoma involving the mucosa-associated lymphoid tissue. Most commonly affected organ is the stomach. But, it could affect almost every organ in the whole body. If they have suspicious lesion, excision biopsy could be made. For staging, blood test including blood smear, abdomen and chest tomography or scan will be checked. Also, bone marrow test can be done if it is needed. The patient had visited the clinic for palpable mass on right lower eyelid. With excisional biopsy, it was diagnosed as lymphoid hyperplasia on pathologic test. But 2 years later, the patient came with recurrent symptom for our department with worry. At that time, we recommended excisional soft tissue biopsy under general anesthesia. Unfortunately, it was revealed MALT lymphoma on pathologic finding. It turned out to be stage 3 in Ann Arbor staging system without B symptoms. Hematologic consultation was made and she was treated with adjuvant chemotherapy for eight cycles to complete remission. We report a case of MALT lymphoma on subcutaneous tissue at right lower eyelid previously diagnosed as lymphoid hyperplasia.

Comparison of postoperative pain according to the harvesting method used in hair restorative surgery

BACKGROUND: Postoperative pain is one of the most common concerns of patients undergoing hair transplantation surgery. Because most patients are satisfied with the cosmetic improvement after transplantation, amelioration of postoperative pain would help to increase patient accessibility to hair restorative surgery and greatly impact patient satisfaction with the final cosmetic results. This study was performed to investigate postoperative pain after hair transplantation. METHODS: In total, 241 patients (202 who underwent follicular unit transplantation [FUT] and 39 who underwent follicular unit extraction [FUE]) were eligible for the study. Postoperative pain was evaluated on postoperative days 1, 2, 3, 4, 5, and 7 using the Wong-Baker Faces Pain Scale. The patients’ medical records were retrospectively reviewed for information on the harvesting method, number of transplanted grafts, size of donor design, and laxity, elasticity, and glidability of the scalp in relation to postoperative pain. RESULTS: Postoperative pain after hair transplantation, assessed with the Wong-Baker Faces Pain Scale, seemed to provide very subjective results. None of the variables were correlated with postoperative pain in the FUT group. Such pain, however, tended to disappear by postoperative day 3. Patients in the FUE group experienced significantly less severe pain than those in the FUT group. CONCLUSIONS: Postoperative pain was significantly less severe in patients whose donor hair was harvested by the FUE than FUT method. Postoperative pain had almost disappeared by postoperative day 3 in the FUT group, whereas only minimal pain was present even on postoperative day 1 in the FUE group.

Hair transplantation in patients with hair loss or scar deformity in the side hairline after midfacelifting surgery

BACKGROUND: Successful aesthetic plastic surgery is devoid of both unsightly scarring and postoperative disfigurement. Patients undergoing midface-lifting surgery are very often disconcerted by an altered side hairline, including sideburns, despite considerable amelioration of facial wrinkles. This study was conducted to identify an effective means of approaching an altered hairline and the unavoidable scarring arising from midface-lifting surgery. METHODS: A total of 37 patients who underwent corrective surgery with hair transplantation for hair loss or scar deformity arising from midface-lifting surgery from June 2014 to June 2017, and were observed for more than 6 months thereafter, were enrolled in the study. Prior to corrective surgery, the patients were administered a multiple-choice survey regarding their dissatisfaction arising from midface-lifting surgery. Among the 37 patients, 24, 12, and one underwent donor harvesting by the strip method, non-shaven follicular unit extraction, and partial shaving follicular unit extraction, respectively. Additionally, 33 of the 37 patients underwent hair transplantation in the frontotemporal recess area along with hairline correction surgery. The average number of transplanted grafts was 1,025. RESULTS: Surgery resulted in a natural and satisfactory appearance in all patients. The average patient and physician subjective satisfaction scores were 4.6 and 4.8, respectively. No adverse events such as folliculitis occurred. CONCLUSIONS: Side-hairline correction surgery by hair transplantation can be considered an effective method of realigning an altered hairline accompanied by scars following midfacelifting surgery.

Wound healing effect of regenerated oxidized cellulose versus fibrin sealant patch: An in vivo study

BACKGROUND: Topical hemostatic agents are used when ligation, electrocauterization, or other conventional hemostatic methods are impractical. Because a hemostatic agent is a foreign body, it can cause foreign body reactions, inflammation, and infections that can interfere with the wound healing process. Therefore, we should select hemostatic agents after considering their effects on wound healing. Here, we compared the effects of hemostatic agents on wound healing in a rectus abdominis muscle defect in rats. METHODS: Twelve Sprague Dawley rats were subjected to creation of a 6 × 6 mm defect in the rectus abdominis muscle and divided into four groups: control group; group A, Tachosil fibrin sealant patch; group B, Surgicel Fibrillar oxidized regenerated cellulose; and group C, Surgicel Snow oxidized regenerated cellulose. For the histologic analysis, biopsies were performed on the 3rd, 7th, and 27th days. RESULTS: The foreign body reaction was the weakest in group A and most significant in group C. The inflammatory cell infiltration was the weakest in group A and similar in groups B and C. Muscle regeneration differed among periods. The rats in group A were the most active initially, while those in group C showed prolonged activity. CONCLUSION: Tachosil and Surgicel administration increased inflammation via foreign body reactions, but the overall wound healing process was not significantly affected. The increased inflammation in the Surgicel groups was due to a low pH. We recommend using Tachosil, because it results in less intense foreign body reactions than Surgicel and faster wound healing due to the fibrin action.

Primary orbital tuberculosis on the lower eyelid with cold abscess

Orbital tuberculosis is a rare form of extrapulmonary tuberculosis, even in endemic areas. It may involve the soft tissue, lacrimal gland, periosteum, or bones of the orbital wall. We present a case of orbital tuberculosis on the lower eyelid. An 18-year-old woman with no underlying disease visited our clinic for evaluation of an oval nodule (1.5× 1.2 cm) on the right lower eyelid. Incision and drainage without biopsy was performed 2 months ago in ophthalmology department, but the periorbital mass had deteriorated, as the patient had erythematous swelling, tenderness, and cervical lymphadenopathy. Visual acuity was normal; there were no signs of proptosis, diplopia, or ophthalmoplegia. Computed tomography revealed a small abscess cavity without bony involvement. We performed an excision and biopsy through a percutaneous incision under local anesthesia. Histological examination revealed a granuloma and was diagnosed as orbital tuberculosis. The patient was additionally treated with anti-tuberculosis therapy for 6 months and recovered without complication or recurrence by 7 months. Orbital tuberculosis occurs in patients with or without associated pulmonary tuberculosis, and should be considered as a differential diagnosis in patients with inflammatory orbital disease and an orbital mass. If recurrence occurs despite adequate initial treatment, we recommend an additional examination and excisional biopsy.

Malignant pilomatricoma of the cheek in an infant

Malignant pilomatricoma (pilomatrical carcinoma) is a rare, locally occurring malignant tumor with a high rate of recurrence in the case of incomplete excision. This tumor has two characteristics. First, recurrences of pilomatrical carcinoma are common; second, distant metastasis is rare, but if it occurs, it is very fatal. It has characteristic features of high mitotic counts, cellular atypia, and local invasion. Although fine needle aspiration and excisional biopsy could help to confirm this tumor diagnosis, pathologic findings are critical. Pilomatricomas have some characteristic features in histological aspect, such as epithelial islands of basaloid cells and shadow cells or ghost cell. Also, various types of immunohistochemical staining are used to confirm the diagnosis. Despite the lack of clear surgical criteria, treatment is a wide local excision with histologically clear resection margins with or without adjuvant radiotherapy.

Hair Diameter Variation in Different Vertical Regions of the Occipital Safe Donor Area

BACKGROUND: Little is known concerning hair diameter variation within the safe donor area for hair transplantation surgery. Thicker or thinner hair may be needed, depending on the recipient area, hairline design, and the purpose of surgery. METHODS: Twenty-seven patients (7 men and 20 women; mean age, 28 years; range, 20–47 years) were included in this study. The midoccipital point was used as the reference point on the horizontal plane at the upper border of the helical rim. The target area width was 15 cm (7.5 cm to the right and left of the reference point) and the height was 8 cm (2 cm above and 6 cm below the reference point). The study area was divided horizontally into 3 5-cm sections (A, B, C) and vertically into 4 2-cm sections (1–4), creating a total of 12 zones. Ten anagen hairs were randomly obtained from each zone and their diameters were measured. RESULTS: Hair diameter in the 4 vertical sections varied significantly, gradually decreasing from sections 1 (superior) to 4 (inferior) in all 3 horizontal sections (A, B, and C). CONCLUSIONS: Our results suggest that sections 1 and 2 of the occipital safe donor area would be useful for obtaining thicker hair, such as in procedures to treat male- and female-pattern hair loss, whereas hair from zones 3 and 4 could be useful for transplantation surgery requiring thinner hair, such as eyebrows, eyelashes, and female hairline correction. Our results may be clinically valuable for planning hair transplant surgery and choosing the optimal donor region.

Predicting the Permanent Safe Donor Area for Hair Transplantation in Koreans with Male Pattern Baldness according to the Position of the Parietal Whorl

BACKGROUND: The most crucial factor in hair transplantation for male pattern baldness (MPB) patients is the efficient utilization of the donor-recipient ratio. However, there is no known factor that scientifically predicts the rate of progression of alopecia or indicates a permanently safe donor area. METHODS: The study considered 1,008 Korean adult males with MPB; of these, it excluded 56 males with an absence of parietal whorls (PWs). The authors investigated the distance from the vertical bimeatal line (VM) to the PW, from the PW to the upper border of the helical rim (HR), and the distance from the PW to the occipital fringe (OF) in 952 subjects with a PW. Furthermore, we examined the distance from the PW to the OF considering the duration of alopecia and age in 322 subjects with vertex alopecia. RESULTS: The distance between the VM and PW varied from 1.5 to 11 cm, with an average distance of 6.25 cm. The PW-HR distance ranged from 3.4 to 17.5 cm, and the average distance was 7.79 cm. The PW-OF distance ranged from 0.5 to 5.5 cm, and the average distance was 2.37 cm. CONCLUSIONS: For the PW, very large variations existed in the vertical direction. The position of the PW could predict the progression range of the total alopecia of the vertex. Alopecia mostly progresses within 6 cm of the PW toward the occipital side.

The Effects of Topical Agent (Kelo-Cote or Contractubex) Massage on the Thickness of Post-Burn Scar Tissue Formed in Rats

BACKGROUND: We conducted an experimental study to compare the effect of massage using topical agents (Kelo-cote or Contractubex) on scar formation by massaging the healed burn wound on the dorsal area of Sprague-Dawley (SD) rats. METHODS: Four areas of second degree contact burn were made on the dorsal area of each of 15 SD rats, using a soldering iron 15 mm in diameter. After gross epithelialization in the defect, 15 SD rats were randomly divided into four groups: the Kelo-cote group, Contractubex group, Vaseline group, and control group. Rats in three of the groups (all but the Control group) were massaged twice per day for 5 minutes each day, while those in the Control group were left unattended. For histologic analysis, we performed a biopsy and evaluated the thickness of scar tissue. RESULTS: In the Kelo-cote and Contractubex groups, scar tissue thicknesses showed a significant decrease, compared with the Vaseline and control groups. However, no significant differences were observed between the Kelo-cote and Contractubex groups. In the Vaseline group, scar tissue thicknesses showed a significant decrease, compared with the control groups. CONCLUSIONS: The findings of this study suggest that massage using a topical agent is helpful in the prevention of scar formation and that massage only with lubricant (no use of a topical agent) also has a considerable effect, although not as much as the use of a topical agent. Thus, we recommend massage with a topical agent on the post-burn scar as an effective method for decreasing the scar thickness.

Comparison of the Wound Healing Effect of Cellulose and Gelatin: An In Vivo Study

BACKGROUND: Many topical hemostatics are widely applied for bleeding control. They can be classified into two categories according to their mechanism of action on the clotting cascade in a biologically active or passive manner. Passive hemostatics include cellulose and gelatin. We performed an experimental study to compare the effect of passive hemostatics in wound healing by applying them to a rectus abdominis muscle defect of white mice. METHODS: Surgicel is a sterile absorbable knitted fabric prepared by the controlled oxidation of regenerated cellulose. Spongostan is an absorbable hemostatic gelatin sponge. In 30 mice, a 1x1 cm defect was created on the rectus abdominis muscle and the materials were applied in three ways: control group, cellulose (Surgicel) group, gelatin (Spongostan) group. For the histologic analysis, biopsies were performed at 3 and 28 days. RESULTS: After 3 days, the cellulose group showed limited granulation formation with acute inflammatory reactions similar to the control group. At the 28th day, moderate amounts of granulation tissue formation was observed with milder inflammatory reactions than the control group. In the gelatin group, after 3 days, gelatin remnants were observed surrounded by severe inflammatory changes. After 28 days, the same quantity of gelatin remnants could be still observed. CONCLUSIONS: This study suggests that cellulose is associated with minimal morbidity in wound healing, while the use of gelatin shows severe adverse tissue reactions with delayed wound healing. Consequently, cellulose is better than gelatin when considering wound healing.

Dandy-Walker Syndrome with Submucous Cleft Palate: A Case Report

PURPOSE: Dandy-Walker syndrome is a rare congenital brain malformation that occurs one in every 25,000-35,000 live births, mostly in females. It is characterized by cystic enlargement of the fourth ventricle, agenesis or hypogenesis of the cerebellar vermis and enlargement of the posterior fossa. In this report, the authors aimed to address a rare case of a 14-months-old female Dandy-Walker syndrome patient that is presented with submucous cleft palate. METHODS: A 14-months-old female patient admitted to our outpatient clinic, via the department of pediatrics, with the complaints of nasal regurgitation, choking and breathing difficulties. She was diagnosed as Dandy-Walker syndrome by magnetic resonance imaging evaluation, at another hospital and underwent a shunt operation for the hydrocephalus continuing treatments. On physical examination, she had structural abnormality of bifid uvula, and palpable notch in the posterior surface of the hard palate. Her submucous cleft palate was corrected, which used a double opposing Z-plasty under general anesthesia. RESULTS: In a follow-up period of 2 months, no complications, such as wound dehiscence, necrosis and infection occurred, which shows satisfactory results. She consulted with pediatric neurologists and physical therapists for further evaluation and management of the abnormalities in the central nervous system. CONCLUSION: Dandy-Walker syndrome patient with a cleft palate is a very rare case to find, which only a few cases are reported around the world. Authors would like to share this case of Dandy-Walker syndrome patient, with submucous cleft palate, who underwent a double opposing Z-plasty that shows satisfactory results.

Effectiveness of Vicryl plus(R)(Ethicon, USA) in Nosocomial Bacteria

PURPOSE: Surgical site infections(SSIs) are the third most frequently reported nosocomial infection. Of these SSIs, mostly were confined to the incision associated with underlying disease as diabetes, cigarette smoking, systemic steroid use, obesity, operating room environment, suture and surgical technique. This study has been planned to reduce the SSIs by using Vicryl plus(R)(Ethicon, USA) which contains triclosan, a broad-spectrum antibacterial agent, into the infected wound to evaluate whether or not Vicryl plus(R)(Ethicon, USA) is effective to nosocomial bacteria using a zone of inhibition assay. METHODS: We did a comparison of Vicryl plus(R) suture(with triclosan) size 2-0, 5-0 with Vicryl(R) suture(without triclosan) size 4-0 each as treatment and control group, applied in Mueller-Hinton agar infected by following mircroorganisms: Methicillin-sensitive Staphylococcus aureus (MSSA), Methicillin-resistant Staphylococcus aureus (MRSA), Acinetobacter baumanii, Escherichia coli, Enterobacter faecalis, Pseudomonas aeruginosa, Candida albicans. Cultures were made of the selected mircroorganisms, seeding the study strain in agar plates for 24 and 48-hour period in an oven at 37degrees C followed by zone of inhibition assay. RESULTS: Vicryl plus(R) group has demonstrated to create a zone of inhibition against MRSA, MSSA and A. baumanii, but no effect on E. faecalis, P. aeruginosa, C. albicans. Vicryl plus(TM) suture size 2-0 also had antibactericidal effect while Vicryl plus(R) suture size 5-0 did not. Vicryl(R) group had no zones of inhibition showing colonization at all mircroorganisms. CONCLUSION: Our results seem to warrant the use of Vicryl plus(R) as absorbable buried suture when concerning SSIs as a prophylaxis against surgical nosocomial infection.

Efficacy of Mepitel(R) in Treatment of Second Degree Burn

PURPOSE: The last decade has focused on healing as the major outcome of burn management with little attention paid to other important patient-centered outcomes, such as pain. Traditional standard dressings using silver sulfadiazine cream and vaseline gauze may result in significant pain at dressing change, wound dryness, increase necessity for dressing change, and also traumatizing the skin and wound bed. In this paper we introduce Mepitel(R), a new silicone dressing material showing satisfactory result than previous traditional standard dressings in burn dressing. METHODS: We conducted a prospective, observational study of 15 adult patients with second degree burn. At the arrive, we initially applied Mepitel(R) after bullae aspiration and changed the cover dressing depending on the degree of exudate from burn while still applying Mepitel(R) for 3 days. After dressing change, pain intensity was measured on an 11-point numeric rating scale. RESULTS: Mean time to wound reepithelization was 10.2 days and mean pain scores on a 11-point scale associated with dressing changes was 5.2 while requiring 0.5 intravenous narcotic administrations per dressing change. CONCLUSION: Mepitel(R) is a new grid like silicone coated nylon dressing containing no additional biologic compounds. The advantages of the Mepitel(R) are easy of use, non-adhesion to the wound, very good tolerance, keep moisture of wound and absence of pain during dressing change. This product has been used in our clinics and this paper serves as a report on our experiences with it.

Effect of Music Therapy on Anxiety and Vital Sign of Nasal Closed Reduction Under General Anesthesia

PURPOSE: Most of the patients who underwent surgery feels variable kinds of fear or anxiety; an uncomfortable mood state that happens without specific object affects patient's satisfaction before and after the surgery. As music therapy is rather noninvasive method generally used in reducing patient's anxiety, the authors researched about the extent of anxiety with the change of vital sign before the operation while comparing with the cases of patients who took the music therapy at closed reduction under general anesthesia. METHODS: We divided the patients in 4 groups; A with the premedication(Midazolam, Dormicum(R)) before the operation, B with the premedication and music therapy, C with only music therapy, D with no premedication or therapy. And we measured the vital signs after the arrival at the operation room, after induction and 20 minutes after the operation. Also we observed the changes of anxiety index with the STAI(State Trait Anxiety Inventory)-K(Korea)YZ 1 hour before and 8 hours after the surgery. RESULTS: The group B showed the least changes in blood pressure as the group D showed the highest change. Both group C and A showed increase in blood pressure but the upswing in group A was lower than group C. At the change of pulse rate group B showed the lowest upswing also group D showing the highest. Group B showed quite a few upswing but lower than group D, but, at the same time, group A showed lower upswing when comparing two cases. After analysis of STAI-KYZ score, the anxiety relatively decreased in group B and C in comparison with group D. And the index of anxiety state of group A showed just as much to group D. CONCLUSION: The music therapy is better healthcare method compared to other therapies in reducing anxiety also with satisfying effect who underwent operation. The authors recommend music therapy assisted with use of premedication for better relief of anxiety.

A Case of Giant Sacral Chordoma

PURPOSE: Chordoma is a rare primary osseous tumor arising from the remnants of the primitive notochord. It occurs once in 2,000,000. It is characterized by its slow growth, high frequency to invade destroy bone by direct extension. We experienced giant sacral chordoma and reconstructed with gluteal advancement flap. METHODS: A 52-year-old woman presented with a 2-years history of gluteal pain. In the biopsy study revealed sacral chordoma. MRI study showed 13 x 12 x 10 cm sized m0cs. We approached anterior and posterior resection and reconstructed with bilateral gluteus maximus advancement flap. RESULTS: After the operation, blader and anal function were slightly decreased. But, 4 months later those were almost fully recovered. There was no significant complication and recurrence after 2-years follow-up. CONCLUSION: Chordoma is characterized by its slow growth, high frequency to invade and destroy bone by direct extension. Wide surgical resection is the only curative procedure. We report a ase of giant sacral chordoma which was successfully treated by anterior and posterior approach and reconstructed with bilateral gluteal advancement flap.
