A 65-year-old woman with a deeply infiltrating basal cell carcinoma in the right ala underwent full-thickness excision of most of the ala, including the alar rim, crease, and the adjacent cheek, leaving a 'through-and-through' defect. Reconstruction was performed by using the reverse nasolabial flap and a cartilage graft across the alar defect, harvested from the concha, to prevent nostril collapse and to maintain the alar shape. The reverse or turnover nasolabial flap is a variant of the conventional nasolabial flap; however, it may be more suited for the repair of a full-thickness, lateral alar defect. The reverse nasolabial flap functions both as an inner liner and an outer cover and the repair is performed as a single-stage procedure. Furthermore, this flap can provide both excellent function and excellent cosmetic outcome.

BACKGROUND: Port-wine stain (PWS) is a congenital capillary malformations characterized by ectasia of capillaries and venules. These vascular channels progress gradually to hyperplasia of soft and hard tissues, manifested as hypertrophy of involved structures. Especially, when these lesions involve the lip, macrocheilia may develop with time. Usually vascular-specific laser treatment is used for PWS, however with no favorable effect with soft-tissue hypertrophy. Therefore, surgical treatment may be necessary in such cases. OBJECTIVE: The subjects were 9 patients who had PWS with lip hypertrophy, who were aged from 9 to 65 years. METHODS: The patients underwent cheiloplasty which include making an incision horizontally on a labial mucosa of the lip, and dissection of hypertrophied soft tissue in the front and back of the orbicularis oris muscle. RESULTS: Of the 9 patients, only 2 had postoperative complication such as mild chewing of the labial mucosa. After a minor revision surgery, these symptoms disappeared. Good to excellent results were achieved in all patients during the final postoperative cosmetic evaluation. CONCLUSION: Surgical correction is appropriate for treatment of three-dimensional tissue deformity such as lip hypertrophy with good cosmetic results and minimal complications.

BACKGROUND: Extramammary Paget disease (EMPD) is an uncommon malignant neoplasm affecting apocrine gland-bearing skin which usually occurs in the anogenital area of patients older than 50 years. Although Mohs micrographic surgery (MMS) is recommended for the treatment of EMPD, wide local excision has also been performed by many other surgeons including dermatosurgeons. However, the extent of an adequate resection margin is still under debate. OBJECTIVE: The efficacy of minimal surgical therapy consisting of a wide excision combined with preoperative multiple scouting biopsies and postoperative topical imiquimod was investigated for the treatment of EMPD in Korean patients. METHODS: Between 2006 and 2012, 10 patients with primary EMPD were treated with wide surgical excision, with a surgical margin of less than 2.5 cm. Multiple preoperative scouting biopsies and postoperative topical imiquimod were also performed to delineate the lesional boundaries and to reduce the recurrence rate. RESULTS: During the 6-year follow-up period, complications and recurrences were not observed. CONCLUSION: Minimal surgical therapy may be an effective alternative when MMS is unavailable.

Merkel cell carcinoma is a malignant neuroendocrine tumor with a high rate of recurrence and metastasis. However, approximately 23 cases of spontaneous regression have been reported. We report a case of Merkel cell carcinoma which showed spontaneous regression. The patient was an 84-year-old male with a large red-colored, hemispheric tumor on the left inner thigh which had been presented for a year. We planned to perform surgery, but the tumor suddenly started to regress spontaneously. The size of the tumor decreased, the surface was flattened, and the color changed from red to brown. The lesion finally appeared as a brownish flat plaque. Excision of the regressed tumor was performed; immunohistopathological analysis showed CD3+ T cells infiltrating around the regressed merkel cell carcinoma.

BACKGROUND: Desmocollins (Dsc) are calcium-dependent transmembrane glycoproteins of desmosomes that are important in the junction complex of epidermis and maintain structural integrity of the skin from external stressors. Among three Dscs (Dsc 1, 2, 3), Dsc 1 and 3 are distributed on skin. OBJECTIVE: The purpose of this study was to observe the Dsc 1 distribution pattern on the skin and oral mucosa during fetal development. METHODS: Skin was obtained from the sole and scalp of 33 fetuses, ranging from 10 to 37 weeks of gestational age. Immunohistochemical staining was performed on the paraffin-embedded tissue using a Dsc 1 monoclonal antibody. RESULTS: Dsc 1 was expressed in the suprabasal layer but not in the basal layer of the epidermis of the sole at the 10th week of gestation. Thereafter, Dsc 1 expression further increased in the suprabasal layer with initiation of stratification and increased gradually in the granular layers of the sole and scalp epidermis. Dsc 1 was strongly expressed in the superficial layer of the infundibulum and inner root sheath of the hair follicle but was not expressed in the sebaceous cells or other hair components. The eccrine duct epithelium was focally and weakly positive for Dsc 1 expression. Furthermore, Dsc 1 was not expressed in oral mucosa, although the oro-cutaneous portion was strongly expressed in the superficial layer. CONCLUSION: Dsc 1 was strongly expressed in the suprabasal cells of the epidermis during fetal skin development, and expression increased gradually in the granular layer and inner root sheath of the hair follicle. However, Dsc 1 was not expressed in basal cells or in oral mucosa. Dsc 1 may play a role in the maintenance of epithelial integrity as part of desmosomes.

Lymphoepithelioma-like carcinoma is a neoplasm at extranasal sites with striking histological similarity to lymphoepithelioma arising in the nasopharynx. The tumor is composed of islands of pleomorphic cells with a lymphocytic infiltrate. The head and neck are the principal locations for this tumor, which occurs in the skin. Differential diagnoses include squamous cell carcinoma, Merkel cell tumor, lymphoma, cutaneous lymphadenoma, malignant melanoma, and metastatic lymphoepithelioma. Here, we report a case of lymphoepithelioma-like carcinoma of the skin in a 78 year-old male who had a firm nodule on the right upper eyelid. He was treated with wide excision and local flap coverage. The patient had been disease-free for more than 1 year.

Scleromyxedema is a rare disorder characterized by generalized papular and sclerodermoid eruption, increased fibroblast proliferation, mucin deposition, and monoclonal gammopathy in the absence of thyroid disease. It is a generalized subtype of lichen myxedematosus. A paraproteinemia, typically an IgG lambda, is observed in more than 80% of patients with scleromyxedema. Here, we report a 38-year-old woman with a 1-year history of a progressively spreading of eruption of small papules on the entire body, including the face, neck, arms, legs, and trunk. Laboratory tests were within normal limits, except lambda light chain monoclonal gammopathy. We administered oral retinoid and topical steroid with slight clinical improvement. To our knowledge, this is the first reported case of scleromyxedema in Korea.
