Cutaneous odontogenic sinuses are the most common cause of chronic draining sinus tracts on the face and neck. These lesions present as erythematous nodules with surrounding dimples, which intermittently drain purulent fluid. Although most patients do not have dental symptoms, careful questioning of a patient`s past symptoms may help the clinician identify a dental etiology. A history of toothache in the affected area that resolves without dental intervention is useful information. Clinical and radiographic examination may reveal carious teeth with radiolucent areas. Elimination of the source of infection by endodontic treatment or tooth removal results in resolution of the sinus tract, typically within 2 weeks. Early precise diagnosis and appropriate dental treatment can circumvent unnecessary and ineffective antibiotic therapy or surgical treatment. We report a case of a cutaneous odontogenic sinus in the right cheek area. (Korean J Dermatol 2009;47(3):330∼333)

Cutaneous pseudolymphoma refers to a heterogeneous group of benign reactive T- or B-cell lymphoproliferative diseases of the skin that resembles cutaneous lymphoma both clinically and histologically. Although most pseudolymphomas develop from unknown causes, various stimuli can induce pseudolymphomas. Pseudolymphomas have developed followed medications, infections, insect bites, ear piercing, and gold. To date, no case of pseudolymphoma developing after gold acupuncture has been reported in the Korean dermatologic literature. We report a case of a 49-year-old female who presented with multiple skin-colored papules on the left lower eyelid that showed features of a pseudolymphoma based on histopathologic assessment.

Cervical accessory tragus is a rare congenital malformation presenting at birth as a firm nodule on the neck along the anterior edge of the sternocleidomastoid muscle. It has also been reported under different names, such as elastic cartilage choristoma of the neck, Meckel`s cartilaginous remnant, cervical tab, cervical auricle, and wattle. Histologically, cervical accessory tragus is composed of numerous hair follicles, and a prominent connective tissue framework in the subcutaneous fat and central core of cartilage. We report a case of an 8-year-old female who presented with a solitary flesh colored papule on the posterior neck that was histopathologically diagnosed as cervical accessory tragus.

Cutaneous larva migrans (CLM) is an uncommon cutaneous creeping eruption caused by the invasion and migration of nematode larvae into the skin. Burrowing larvae produce intensely pruritic, serpiginous, raised erythematous skin lesions. Most cases of CLM reported in Korea involved travelers returning from endemic areas with tropical or subtropical climates. We report herein a case of CLM with no history of travelling to endemic area and briefly review the relevant literature. (Korean J Dermatol 2010;48(3):250~252)

A glomus tumor is a kind of hamartoma that was first described by Masson in 1924. There are two major clinical forms of glomus tumor: solitary and multiple. Solitary glomus tumor which usually occurs in older age is characterized by a painful pink to red colored papule. A 2-week-old female infant presented to our department with a 1.3×0.4 cm sized tumor on her right foot, which had been present since birth. Histopathologic examination showed many vessels lined by thin endothelial cells and multiple rows of glomus cells. Ultrasonography of the foot revealed intense blood supply in the tumor bed. We diagnosed the patient with a congenital solitary glomus tumor, based on history, skin lesion, ultrasonography, and histopathologic findings. We report a case of a congenital, solitary glomus tumor in a 2-week-old female infant. (Korean J Dermatol 2009;47(3):347∼349)

In order to explore the possibility to extract precious metals from PCB(Printed Circuit Board) scrap by gravity separation, a high temperature melting process was adopted, from the recycling view point, to investigate the influence of viscosity on A1$_2$$O_3$-CaO$-SiO_2$ slag system composed of PCB scrap. For optimizing the pre-treatment process of PCB scrap, an experimental condition for the complete calcination and oxidation of organic materials in PCB scrap was established and a quantitative analysis of oxidized PCB scrap was also carrie out. It was found that 6 hours were enough for the complete oxidation of PCB scrap at 1273 K in an atmosphere condition. A slag, l5wt%$A1_2$$O_3$-45wt%CaO-40wt%SiO$_2$, was chosen as a basic slag composition which is determined based on the quantitative analysis of PCB scrap. Viscosities were measured in slag systems both made from pure fluxes and from PCB scrap with additional fluxes. Slag viscosities composed of pure fluxes were measured to be 5.29 poise and 30.52 poise at temperatures of 1773 and 1573 K, whereas that of PCB scrap with additional fluxes were 3.37 poise and 69.89 poise, respectively.

Background: The incidence of cutaneous malignant tumors and premalignant lesions has recently increased according to extended life span, social and medical environment changes. However, a few clinical data have been reported on the survey of cutaneous malignant tumors and premalignant lesions in Gangwon province. Objective: To investigate the incidence and clinical patterns of cutaneous malignant tumors and premalignant lesions in Gangwon province. Methods: We reviewed 485 cases of cutaneous malignant tumors and premalignant lesions from January 1999 to December 2008, at the Department of Dermatology at Wonju Christian Hospital. Results: The average annual incidence of cutaneous malignant tumors among the total number of outpatients was 0.51% and that of premalignant lesions was 0.48%. Both incidences tended to increase with time in 10 year intervals. The most common cutaneous malignant tumor was basal cell carcinoma (47.98%), followed by squamous cell carcinoma (24.19%), extramammary paget`s disease (7.26%), metastatic cancer (5.65%), malignant melanoma (4.44%), and lastly, lymphoma (4.44%). Among premalignant lesions, actinic keratosis (74.68%) and Bowen`s disease (25.32%) were common. The mean age of onset was 67.53 years in cutaneous malignant tumors and 70.51 years in premalignant lesioins. The most common site for both, the cutaneous malignant tumors and premalignant tumors, was the face (63.97% and 81.43%, respectively). The ratio of men to women was 1.11:1 in cutaneous malignant tumors and 1:2.48 in premalignant lesions. Conclusion: The incidence of cutaneous malignant tumors and premalignant lesions has gradually increased in Gangwon province. This data will be made available for the study about the association of cutaneous malignant tumors and premalignant lesions. (Korean J Dermatol 2012;50(2):95~100)

Folliculitis is an inflammatory disease that has various causes. It has been widely reported to be caused by exposure to industrial oil such as cutting oil and diesel oil. A 39-year-old man presented with multiple diffuse erythematous papules with a follicular distribution on the anterior chest, back and shoulder. The histopathologic findings of the papules showed follicular epithelial destruction and a perifollicular inflammatory cellular infiltration. He was diagnosed as having folliculitis. The distribution of lesions matched with the area of tanning oil application was identical to that of the patient`s applying tanning oil before the development of skin lesions. We report here on a case of folliculitis due to applying tanning oil. Tanning oil caused the follicular occlusion and dilatation in hairless mice in one experiment.

Merkel cell carcinoma is a rare and lethal skin cancer that mostly occurs in aged persons who are over 60 years old as a dome-shaped purple nodule on the sun-exposed areas of the head, neck and extremities. The mortality rate is high because this tumor has a propensity for local recurrence, regional lymph node metastasis and distant metastasis. Therefore, rapid and precise diagnosis and staging are critical to improve the prognosis. We reported here on a 68-year old man with Merkel cell carcinoma on his right cheek and he had regional cervical lymph node metastasis, as was detected by PET-CT scanning.
