Cutaneous horn is a morphologic designation for a projectile, conical, dense hyperkeratotic nodule that resembles the horn of an animal. The lesion varies in size from only a few millimeters to several centimeters, in color(white or yellowish) and in form (straight, curved, or twisted). It arises from a wide range of epidermal lesions, which include benign lesions, premalignant lesions and malignant lesions. An 83-year-old women came to our clinic with a giant cutaneous horn on the right chin and a small horn on the left upper eyelid. The patient had no palpable cervical lymph node. A wide elliptical skin incision was made and the horn was totally excised. In pathology, the giant cutaneous horn on the right chin revealed a moderately differentiated squamous cell carcinoma with subcutis invasion at its base. "Giant cutaneous horns" have often been associated with invasive squamous cell carcinoma. Cutaneous horns are common lesions usually found on the face, rarely larger than 2 cm. As large cutaneous horns are often associated with underlying malignancy, histopathologic examination of the base of the lesion is necessary to rule out carcinoma and full excision is recommended.

The odontogenic cutaneous fistula in facial area is uncommon but, well defined disease. It is difficult to diagnose from the dental origin of cutaneous sinus tract. Most patients may visit to the dermatologists or general hospital without cause of disease. They usually be treated by repeated surgical excisions, biopsies, and antibiotic medications, but suffered from recurrences. We studied odontogenic cutaneous fistula through retrospective study in Jeju Special Self-Governing Province between 1 January 2009 and 12 December 2015. There were 3 males, 5 females from 14 to 78 years old with an average age of 50.4 years old. Only 2 patients felt the toothache, others didn't detect it. They suffered from recurrences and repeated treatments for 3 to 11 months with an average period of 7.9 months. They visited average 2.8 hospitals before a precise diagnosis in a dental clinic. All cases were fully healed endodontic treatment or extraction of origin teeth without recurrences. In conclusion, the cause of cutaneous fistula in facial area can be odontogenic. If dentists or doctors diagnose a patient with cutaneous fistula on face, they should check dental problems or take x-ray views for precise diagnosis. It could be helpful for differential diagnosis.

Primary cutaneous anaplastic large cell lymphoma (C-ALCL) is a rare subtype of primary cutaneous lymphoma with a favorable prognosis. Primary cutaneous CD30+ lymphoproliferative disorders, which include C-ALCL and lymphomatoid papulosis, are the second most common group of cutaneous T-cell lymphomas. C-ALCL is comprised of large cells with anaplastic, pleomorphic, or immunoblastic cytomorphology, and indeed, more than 75% of the tumor cells express the CD30 antigen. C-ALCL clinically presents with solitary or localized reddish-brown nodules or tumors, and sometimes indurated papules, and they may be with ulceration covering with dark eschar. Multifocal lesions are seen in 20% of the patients. Extracutaneous dissemination, which mainly involves the regional lymph nodes, occurs in 10% of patients. A 69-year-old man noticed a mild elevated cutaneous lesion containing central ulceration covering with brownish black necrotic tissue on the right lower lip, and the lesion was surgically removed. After the first operation, another skin lesion was developed and the histological examination confirmed the diagnosis, C-ALCL. Eight specimens were excised during the 7-month follow-up period. The patient started the treatment with low-dose oral methotrexate (15 mg/wk) and there was no recurrence for 11 months.

The cutaneous sinus tract is an uncommon disease. It is difficult to diagnose exactly of odontogenic cutaneous sinus tract for dentists or dermatologists except experienced clinicians or previously known clinicians. Many patients may be treated with repeated surgical excisions, biopsies, and antibiotic medications, but most of them could be frustrated with the recurrence of disease. There are several methods for diagnosis of odontogenic cutaneous sinus tract - such as GP cone tracing, conventional computed tomography(CT), periapical x-ray imaging, and cone beam computed tomography(CBCT). This case report describes the diagnosis and treatment of odontogenic cutaneous sinus tract that referred from medical doctors.

Meralgia paresthetica is a disorder characterized by a pain or dysaesthesia, or both, in the anterolateral aspect of the thigh caused by entrapment or neurinoma formation of the lateral femoral cutaneous nerve. Currently available modes of therapy include conservative treatment, lateral femoral cutaneous nerve block with steroids and local anesthetics, and surgery. At our neuro-pain clinic, w recently encountered three cases of meralgia paresthetica, all of which were treated by lateral femoral cutaneous nerve block. In which of them, two cases were successfully treated but one case was associate with pain relapse due to entrapment of lateral femoral cutaneous nerve by a retroperitoneal mass, schwannoma. In this paper we report our experience along with a review of the current literatures.

The cutaneous melanoma has been regarded as rare disease entity in Korea for long time but it shows a silent growth recently. Furthermore the management of cutaneous melanoma including staging system, surgical principle, sentinel lymph node biopsy and subsequent complete node dissection and, most importantly, immunotherapy and target therapy against cutaneous melanoma recently. The incidence of cutaneous melanoma is steadily increasing in Korea but its increase is rapid recent 2 decades to 4.3 times and should be greater soon according to the steeper increase of life expectancy. New staging system proposed by American Joint Committee on Cancer (2017) includes changes in individual TNM category and stage groups, particularly from a prognostic viewpoint. Dermoscopy has been successfully introduced in the differential diagnosis of pigmented skin lesion focusing on cutaneous melanoma by non-invasive simple diagnostic tool. Sentinel lymph node biopsy was a issue of long debate whether survival benefit is real or not. Temporary conclusion about this question is reached after two large scale studies and immediate complete node dissection should be performed in a certain situations. Most important change is drug therapy focusing on immunotherapy and target therapy. Braf- and MEK-inhibitor, immune checkpoint inhibitor and PD-1 blocker has been proved to be effective as a sole or combination regimen against advanced and/or high-risk adjuvant setting of cutaneous melanoma. In conclusion, these remarkable changes will be reviewed shortly here.

This study was performed to evaluate the effectiveness of pharmacoacupuncture treatment of coccygodynia caused by perforating cutaneous nerve entrapment syndrome. Two patients were diagnosed as coccygodynia caused by perforating cutaneous nerve entrapment syndrome which pain was within the anatomical field of the nerve, worsened by pressure-inducing posture, no objective sensory loss and in presence of pin-point tenderness. They were treated by pharmacoacupuncture at perforating cutaneous nerve region penertrating the sacrotuberous ligament and local tenderness point of coccyx. The evaluation of clinical outcome was done by pain intensity numerical rating scale (PI-NRS), pressure pain threshold (PPT) and EuroQol five dimensions questionnaire (EQ-5D) index. After treatment, their PI-NRS was decreased, PPT and EQ-5D index were increased. The pharmacoacupuncture therapy at entrapment point of perforating cutaneous nerve could be an effective way to treat coccygodynia caused by perforating cutaneous nerve entrapment syndrome.

The purpose of this study was to assess the effect of heat therapy on cutaneous blood flow and skin temperature at pre-auricular region. Moist heat therapy and ultrasound therapy were applied to 20 healthy subjects(male: 10, female: 10). Cutaneous blood flow and skin temperature before and after heat therapy were measured with laser doppler flowmetry and thermocouple. The results were as follows ; 1. Cutaneous blood flow and skin temperature were significantly increased after moist heat therapy and ultrasound therapy. 2. In application of moist heat therapy, cutaneous blood flow and skin temperature were more increased and maintained longer than in ultrasound therapy. 3. Before heat therapy, cutaneous blood flow and skin temperature were higher in male. 4. There was no significant gender difference in changes of cutaneous blood flow and skin temperature after heat therapy. In conclusion, both moist heat therapy and ultrasound therapy increased cutaneous blood flow and skin temperature significantly, and moist heat therapy was more effective to increase cutaneous blood flow and skin temperature and to maintain increased cutaneous blood flow and skin temperature. There was no significant gender difference in the effect of heat therapy on cutaneous blood flow and skin temperature.

Cutaneous stimulation and distraction are independent nursing interventions used in various painful conditions, which is explained by gate control theory. This study was aimed at identifying the effect of cutaneous stimulation, distraction and combination of cutaneous stimulation and distraction on the reduction of intravenous injection pain levels of chemotherapy patients. Repeated measurement post test research design was used for one group. Fifty-three cancer patients who received intravenous chemotherapy regulary in outpatient injection rooms of D medical center and Y medical center in Taegu were studied from June 23, 1997 to July 12, 1997. First the intravenous injection pain level of the control period was measured. Second, the intravenous injection pain level of the experimental period using cutaneous stimulation was measured. Third, the intravenous injection pain level of the experimental period using distraction was messured. Fourth, the intravenous injection pain level of the experimental period using a combination of cutaneous stimulation and distraction was measured. The instruments used for this study were a visual analogue pain scale as subjective pain measurement and an objective pain behavior checklist. Analysis of data was done by use of repeated measure ANOVA, bonferni, t-test, and F-test. The results of this study were summerized as follows : 1) The first hypothesis that the subjective pain score of intraveneous injection pain in the experimental period with cutaneous stimulation will be lower than in the control period was rejected. 2) The second hypothesis that the objective pain behavior score of intravenous injection pain in the experimental period with cutaneous stimulation will be lower than in the control period was accepted(F=24.23, p=0.0001, Bornferni p<.05). 3) The third hypothesis that the subjective pain score of intraveneous injection pain in the experimental period with distraction will be lower than in the control period was rejected. 4) The fourth hypothesis that the objective pain score of intravenous injection pain in the experimental period with distraction will be lower than in the control period was accepted(F=24.23, p=0.0001, Bornferni p<.05). 5) The fifth hypothesis that the subjective pain score of intravenous injection pain in the experimental period with combination of cutaneous stimulation and distraction will be lower than in the control period was accepted(F=3.04, p=0.031, Bonferni p<.05). 6) The sixth hypothesis that the objective pain score of intravenous injection pain in the experimental period with combination of cutaneous stimulation and distraction will be lower than in the control period was accepted(F=24.23, p=0.0001, Bonferni p<.05).
