  • Primary cutaneous mucinous carcinoma (PCMC) is a rare low-grade malignant neoplasm derived from the eccrine glands. PCMC most commonly arises in the head and neck, with the eyelid being the most common site of origin. This case report describes a 51-year-old male with a painless, pigmented superficial nodular lesion over his right lower eyelid. The lesion was considered to be benign, and the initial treatment was simple excision with a 3-mm margin. However, histologic examination revealed the diagnosis of PCMC, and the patient underwent re-excision of the tumor site with an additional 3-mm margin from the initial scar. Histologic study of this second margin was free of any malignant cells. The patient experienced no postoperative complication or recurrence after 2 years. In our case, the skin lesion had benign morphologic findings and was strongly suspected to be a benign mass. Physicians should be aware of this tumor and be able to differentiate it from benign cystic or solid eyelid lesions.

  • Primary intracranial malignant melanoma is a very rare and highly aggressive tumor with poor prognosis. A 66-year-old female patient presented a headache that had been slowly progressing for several months. A large benign pigmented skin lesion was found on her back. A brain MRI showed multiple linear signal changes with branching pattern and strong enhancement in the temporal lobe. The cytological and immunohiostochemical cerebrospinal fluid examination confirmed malignant melanoma. A biopsy confirmed that the pigmented skin lesion on the back and the conjunctiva were benign nevi. We report a case of primary intracranial malignant melanoma and review relevant literatures.

  • Purpose: Dermatofibrosarcoma protuberans is a rare tumor, accounting for 0.1% of all malignant tumors. Although metastasis is very uncommon, local recurrence occur frequently. Dermatofibrosarcoma protuberans occurring in children is even more rare; this is the first case report of congenital dermatofibrosarcoma protuberans in Korea. Methods: The patient is a 14-month-old male infant with a lesion that was first thought to be a birthmark. The lesion grew larger, and a punch biopsy revealed dermatofibrosarcoma protuberans. A wide local excision was performed with a 2 cm peripheral resection margin beyond the gross tumor lesion. Deep fascia and a portion of muscle underneath the central part of the lesion were also taken. The surgical defect was covered by a split-thickness skin graft. Results: There has been no clinical sign of recurrence over one year after the surgery. Conclusion: A patient with congenital dermatofibrosarcoma protuberans detected at an early stage underwent a wide local excision of the tumor after accurate diagnosis was carried out by biopsy and immunohistochemical studies. There was no clinical evidence of tumor recurrence during over a 1-year follow-up.

  • A perianal tick and the surrounding skin were surgically excised from a 73-year-old man residing in a southwestern costal area of the Korean Peninsula. Microscopically a deep penetrating lesion was formed beneath the attachment site. Dense and mixed inflammatory cell infiltrations occurred in the dermis and subcutaneous tissues around the feeding lesion. Amorphous eosinophilic cement was abundant in the center of the lesion. The tick had Y-shaped anal groove, long mouthparts, ornate scutum, comma-shaped spiracular plate, distinct eyes, and fastoons. It was morphologically identified as a fully engorged female Amblyomma testudinarium. This is the third human case of Amblyomma tick infection in Korea.

  • Background The elliptical excision is the standard method of removing benign skin lesions, such as congenital melanocytic nevi. This technique allows for primary closure, with little to no dog-ear deformity, but may sacrifice normal tissue adjacent to the lesion, resulting in scars which are unnecessarily long. This study was designed to compare the predicted results of elliptical excision with those resulting from our excision technique. Methods Eighty-two patients with congenital melanocytic nevus on the face were prospectively studied. Each lesion was examined and an optimal ellipse was designed and marked on the skin. After an incision on one side of the nevus margin, subcutaneous undermining was performed in the appropriate direction. The skin flap was pulled up and approximated along several vectors to minimize the occurrence of dog-ear deformity. Results Overall, the final wound length was 21.1% shorter than that achieved by elliptical excision. Only 8.5% of the patients required dog-ear repair. There was no significant distortion of critical facial structures. All of the scars were deemed aesthetically acceptable based on their Patient and Observer Scar Assessment Scale scores. Conclusions When compared to elliptical excision, our technique appears to minimize dogear deformity and decrease the final wound length. This technique should be considered an alternative method for excision of facial nevi.

  • Muir-Torre syndrome is defined by concurrent or sequential development of internal malignancy and sebaceous neoplasm or multiple keratoacanthomas. Muir-Torre syndrome is very rare, with only 205 cases reported in the literature. We reported a patient with Muir-Torre syndrome with three internal malignancies. A 64-year-old patient with a history of breast cancer, stomach cancer and colon cancer visited our department for treatment of the skin lesion that occurred five years before on the left cheek. The lesion was excised completely with a resection margin of 1 cm, followed by full-thickness skin graft from left postauricular area for reconstruction. Histopathology revealed a $0.2{\times}0.2{\times}0.1cm$ sized sebaceous carcinoma with 4 mm safety margin. The skin graft was well taken within 7 days after surgery and the patient was discharged to outpatient follow-up. There was no complication related with surgery. Muir-Torre syndrome is very rare, as are sebaceous gland tumors. So if a cancer of the sebaceous gland is diagnosed, screening workup for internal malignancy is recommended. Because of its good prognosis, surgical removal of primary or metastatic cancers may be curative and should be attempted where possible.

  • Objectives : The purpose of this study is to report the treatment of the Tinea corporis treated by Korean medicine. Methods : The skin lesion with keratin were scraped and placed on a slide glass, and the KOH solution was dropped and observed under a microscope. After the hyphae was confirmed, a ChoPho-bang was prescribed and applied twice a day. Results : In the KOH test performed again 3 weeks after treatment, no hyphae was found and the skin lesion was completely disappeared. Conclusions : For Tinea Corporis, the KOH test is recommended to distinguish it from other skin diseases, and application of ChoPho-bang is effective for treatment.

  • Objective: The root bark of Ulmus davidiana var. Japonica (Ulmi Radicis cortex, URC) is a medicinal herb used for promoting diuresis and treating dampness. In Korea, URC has long been used as an efficacious therapy for inflammation, burns, frostbite and skin diseases such as eczema and psoriasis. Methods: In the present study, we used 1-fluoro-2,4-dinitrofluorobenzene (DNFB)-induced contact dermatitis (CD) mouse model to investigate the anti-allergic and the anti-inflammatory effects of URC on skin lesion, histopathological changes and specific antibody production. Results: URC treatment, 10 mg/mL, effectively inhibited skin lesions induced by repeated paintings with DNFB. In the histopathological observation, topical application of URC inhibited spongiosis. In addition, URC lowered the production levels of total immunoglobulin and IgG2a in serum. Conclusion: These data indicate that URC has an anti-inflammatory effect that produces an improvement of skin lesions in CD mice.

  • Basal cell carcinoma is a malignant epithelial neoplasm of the skin and the most common human skin cancer. It is generally associated with a good prognosis. In this case report, a giant basal cell carcinoma of the nodulo-ulcerative type showing wide ulceration with marginal multiple small nodules, is presented. It was trapezoidal in shape, having dimensions of 7 cm at the greatest basal width, 6 cm vertically with different anterior and posterior margin dimensions, and 5 cm horizontally at the top margin. After wide excision of the lesion including 5-10 mm safety margins, the wound was reconstructed with a local skin flap and split-thickness skin graft. The reconstructed wound healed well without recurrence for 1 year.
