Purpose: Nevus comedonicus is a rare disease involving abnormal development of the pilosebaceous unit, clinically appearing confluent clusters of open comedones. It is characterized by follicular epidermic invaginations filled with keratin, with atrophic pilose or sebaceous structures which are open to the lower pole of the invagination. We report a child with inflammatory pustules and cysts correlated to the nevus comedonicus. Methods: A 15-month-old girl was referred for treatment of a nevus comedonicus that has been developed since birth. There were periodic episodes of erythema and swelling of the plaque. The patient had treated previously with retinoid cream for 2 weeks without obvious benefit at dermatology clinic. We excised the nevus comedonicus with Y-shape leaving some lesions. Results: When we incised skin, we could see multiple large whitish cysts beneath the nevus comedonicus. Histopathologic findings showed deep invagination of epidermis filled with keratin plugs, keratinous cyst in the dermis, rudimentary hair follicle. Conclusion: We treated rare nevus comedonicus with multiple large cysts as surgical excision.

1. The furuncle is nail shaped, whitch tip is sharp and root is deep, very dangerous. It's progress is so rapid and it corresponds to the acute suppurative infection of western medicine. 2. The cause and pathology of the furuncle were divided into three parts, inappropriate care (improper diet and excessive sex), surgical trauma (epidernic infection by domestic animal as like cattle, hoarses, pigs, sheep etc), external evil. 3. The early syndrome of the furuncle is swollen pain, various change of color, fidgetiness, restlessness, aversion to cold, headache, nausea and vomitting etc. Though apply acupuncture, there is no pain and bleeding. There may be streak of blood, curdy of muscles and widen swolling. If it is progressed, its sphere becomes diffuse. This is called as the serious case of furuncle(정독주황). 4. The maim treatment of the furuncle is clear away heat and toxic materials. The method was moxibustion, sticking-plaster, purge blood, oral taking the medicine of detoxication and fire extinguishing etc. 5. The main prescriptionst are omisodokyum(五味消毒飮), hwangyeonheadoktang(黃連解毒湯), ohyangyeongyotang(五香連翹湯), hyeongbangpaedoksan(荊防敗毒散) and so on. The main external prescriptionst are okrhosan(玉露散), cheonchugo(千 膏), guildao(九一丹), palyidan(八二丹), taeyulgo(太乙膏), hongyugo(紅油膏) and so on.

Anal and perianal condyloma acuminatum(CA), which is a large cauliflower-like tumor, is a manifestation of human papillomavirus (HPV) infection. HPV may be acquired via sexual transmission, vertical transmission or nonsexual contact. It is an uncommon condition in children but the incidence in children has been increasing recently. There are many therapies for CA including chemical or physical destruction, immunological therapy, or a surgical excision. All these procedures have some degree of limitations such as limited clearance rate, high recurrence rate, pain, bleeding, release of potentially infectious aerosols and scar. It may be traumatic mentally to the children as well as physically. Korean Medicine included herbal treatment and herbal ointment for CA is no pain, and it doesn't need an anesthesia. We present a case of anal and perianal CA in a 2 years old boy that was treated successfully with Korean Medicine, with no recurrence during the follow up 3 months.

In oriental medicine, 'chi(痔)' is 'the prolapsed nodule' in 'Ku-gyu(九竅)', but in this paper, I will write about prolapsed nodule only in anus or around it, chi-jil(痔疾), it called hemorrhoid in western medicine. So in the literatual studies on chi(痔) in anus or around it, the results are as follows. 1. The etiology and pathogenesis of ch.i-jil(痔疾) is wind, wetness, dryness, and heat caused by inrregular diet habit, severe drinking and sexual action, deficiency of ki(氣) and hyeol(血). 2. Characteristic symptoms of chi-jil(痔疾) is the prolapsed nodule in the anus or around it, and general symptoms are hematochezia, pain, hernia, swelling, abcess, and mucosal secretion. 3. Chi-jil(痔疾) is classified eight types by characteristic symptom, shape, etiology and pathogenesis. They are mac-chi(脈痔), jang-chi(腸痔), ki-chi(氣痔), hyeol-chi(血痔), joo-chi(酒痔), mo-chi(牡痔), bin-chi(牡痔), and loo-chi(屢痔)(or young-chi(영痔), choong-chi(蟲痔)). Additionally, they are divided into two parts, internal and external chi-jil(痔疾), as likely as classification of internal and external hemorrhoid in western medicine. 4. Treatment of chi-jil(痔疾) is two methods, internal treatment and external treatment. Internal treatment is per os herb-pharmacotheraphy, external treatment is surgical or the other external pharmacotheraphy. There are several external treatment, these are fumigation-theraphy(熏痔法). irrigation-theraphy(洗痔法), paint-theraphy(塗痔法). withering-theraphy(枯痔法), bending-therphy(結紮法) and incisal -theraphy(切開法).

A 57-year-old man presented with a pigmented papule, 0.4 cm in diameter, on the left lower eyelid. Skin biopsy revealed a basal cell carcinoma, which was excised through a wide excision followed by a full-thickness skin graft (FTSG). Two weeks after the surgery, an erythematous nodule developed in the lower margin of the graft recipient site. The nodule size increased rapidly over 2 weeks, becoming dome-shaped with a central hyperkeratotic plug. A diagnosis of keratoacanthoma (KA) was made, and surgical excision was performed. Histological findings revealed a large, well-differentiated squamous tumor with a central keratin-filled crater and buttress. The human papilloma virus (HPV) genotyping results were negative. Risk factors for KA include trauma, old age, exposure to ultraviolet (UV) radiation, immunosuppression, and HPV infection. KA has most often been reported to develop at the donor site. Although the pathogenesis of KA is unclear, trauma is believed to act as a second insult to a preceding oncogenic insult, such as exposure to UV radiation, resulting in a koebnerization. Herein, we report a case of solitary KA at a FTSG recipient site. This report presents information that may provide guidance during dermatologic surgeries.

Pachyonychia congenita is a rare genetic disorder characterized by hypertrophic nail plates, hyperkeratotic nail beds, and thickened hyponychium of the fingers and toes, impairing manual dexterity and resulting in poor aesthetics. The current body of literature describes various treatment modalities, but no singular approach has been defined as the gold standard. In this case, the authors employed different surgical techniques for treating pachyonychia congenita to evaluate the most effective approach. A 3-year-old boy presented with hypertrophic nail growth involving all digits of both hands and feet. Three surgical procedures were performed on the patient's fingers and toes using germinal matrix excision (GME) alone, GME plus partial sterile matrix excision (pSME), or GME plus complete sterile matrix excision (cSME). The digits treated with GME + cSME exhibited no recurrence of nail growth. Those treated with GME alone exhibited recurrence of hypertrophic nail growth, although their growth slowed. Excision of GME + cSME prevented recurrence of hypertrophic nails, while GME alone or with pSME led to slower-growing hypertrophic nails. Complete excision of the germinal and sterile matrices with skin graft closure may be a definitive treatment for pachyonychia congenita, but further studies are needed to validate these findings.

A 1.5-year-old neutered male domestic short hair cat was presented with multiple nodular mass, and suspected mast cell tumor on the surface of the right ear, accompanied by submandibular lymph node involvement. Histopathological Examinations and KIT (CD117) immunohistochemical staining was performed after the surgical resection of the entire right ear pinna. This patient was diagnosed with an anaplastic mast cell tumor with a diffuse positive cytoplasmic expression of KIT. Imatinib mesylate was prescribed after surgical resection; the patient presented without recurrence or metastasis for 2 years. Mild leukopenia was observed as the only side effect of imatinib mesylate during medication.

Merkel cell carcinoma is a rare cutaneous carcinoma, featured by an aggressive clinical course and a mortality rate of 28% at 2 years. A 71-year-old female was affected by a 4.1-cm-wide locally advanced Merkel cell carcinoma of the upper eyelid, previously misdiagnosed as chalazion, with involvement of the extraocular muscles. Although the tumor showed a macroscopic spontaneous regression in size after the incisional biopsy, the mass was treated with neoadjuvant chemotherapy and surgical excision. Good functional and aesthetic result with preservation of the eyeball and absence of tumor recurrence were achieved at 3-year follow-up. In our experience, the combination of the inflammatory cascade due to the incisional biopsy and neoadjuvant chemotherapy led to the regression of a locally advanced large Merkel cell carcinoma of the eyelid.

The concurrence of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) in a single tumor is rarely encountered. We report a case of BCC and SCC in a single tumor in the anterior auricular area. A 70-year-old woman had been diagnosed with BCC by a punch biopsy performed at a dermatology clinic. We performed wide excision of the tumor with an ulcer in the anterior auricular area. Analysis of the biopsy specimen revealed the presence of both BCC and SCC in the tumor. This case illustrates that it is necessary to establish a precise diagnosis and formulate appropriate surgical and treatment plans considering the possibility that two carcinomas may coexist, although the possibility is low in patients with skin cancer.

Clear cell hidradenoma is a tumor that originates from a sweat gland and typically involves the dermis and subcutaneous tissue. Malignant clear cell hidradenoma is very rare, and surgical excision is usually performed without imaging. There are few reports of the ultrasonographic findings of malignant clear cell hidradenomas. Herein, we present the ultrasonographic characteristics of a malignant clear cell hidradenoma.
