Title: A Case of Metastatic Lung Cancer in Scalp Mimicking Variant Sarcoma
Biography:
Jung Yup Kim is 3rd grade resident of department of dermatology, Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine.Skin metastasis is a rare clinical entity that has been reported to occur in 0.22%~12% of patients with lung cancer. Besides, skin metastasis as the initial and sole manifestation of an underlying lung cancer is an extremely rare occurrence.
Abstract:
Skin metastasis is a rare clinical entity that has been reported to occur in 0.22%~12% of patients with lung cancer. Besides, skin metastasis as the initial and sole manifestation of an underlying lung cancer is an extremely rare occurrence.
We report a case of a 70-year-old man presenting solitary indurated scar-like nodule on his scalp. He found the lesion three months ago and underwent biopsy at another hospital. After that, he was referred to our hospital because of the suspicion of dermatofibrosarcoma protuberance as a result of biopsy. He did not complain of any other symptoms, and there were no other skin lesions.
We performed additional punch biopsy in our hospital and eccrine adenocarcinoma was found in our biopsy results. So, we did excisional biopsy for confirmative diagnosis. However, histopathologic findings using special staining (thyroid transcription factor-1, napsin) showed a lung-derived metastatic adenocarcinoma. His condition was confirmed with multiple metastases after systemic examinations including chest computed tomography.
Herein, we report a rare case of scalp nodule as an initial presentation of metastatic lung adenocarcinoma.

Title: A Case of Inverted Type A (Clonal) Nevus
Biography:
Department of Dermatology, Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine.Inverted type A (clonal) nevus is a unusual type of melanocytic nevus. It contains pigmented nests of type A nevus cells in the depth of a banal. The nest is occasionally surrounded by type B or C nevus cells. Therefore, type A nevus cells are layered in deeper portion of nevus and Type B and C nevus cells are observed on superficial layers. An unusual presentation of inverted type A nevus have been rarely reported with superficial neurotization.

An unusual presentation of inverted type A nevus have been rarely reported with superficial neurotization.
We described a case of a 68 year-old female complained of solitary, 0.4 cm-sized, dome shaped, brownish to skin-colored papule on the occiput. There was no pruritus or pain on the lesion. The excision biopsy was performed. The histology examination revealed clustered, swirling, epithelioid, type A nevus cells proliferation in the deep portion of perifollicular area. The dense, basophilic type B nevus cells were surrounding the nests of type A cells. Moreover, extensive neurotized type C nevus cells appeared in the upper dermis. No atypia and abnormal mitosis were observed. It could be diagnosed with inverted type A nevus based on the clinical and histological findings.

Title: Title: Secondary Infection of the Umbilical Keloid : Report of Three Cases and Literature Review
Biography:
Department of Dermatology, Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine, 29, Saemunan-ro, Jongno-gu, Seoul, Korea.As many surgical operations have been replaced by laparoscopic surgery, the number of umbilical keloid patients is gradually increasing. Generally, as keloids are painful in the disease itself, clinical differentiation with secondary infection could be difficult.
Abstract:
As many surgical operations have been replaced by laparoscopic surgery, the number of umbilical keloid patients is gradually increasing. Generally, as keloids are painful in the disease itself, clinical differentiation with secondary infection could be difficult. If a thick keloid is formed, it may be a hard problem to confirm the fluctuation and heat sensation in the physical examination. For these reasons, rapid and appropriate surgical intervention can be delayed in numerous umbilical keloid patients.
We experienced three cases of secondary keloid infection in our hospital. In two middle-aged women with tenderness of the keloid, an inflammatory epidermoid cyst was identified by incisional biopsy. Pus from the both patients was sent for microbiological examination, but any significant bacteria growth that might be a pathogenicity factor was not found. Both patients were treated by empirical antibiotics and pus drainage with sterile packing dressing. In the other patient, the cause of repeated keloid inflammation was found to be an iatrogenic small peritoneal defect due to previous surgery. She was sent to general surgery part for additional diagnostic work-up and proper management. From these, we could infer the inflammation of umbilical keloid can be caused by a lot of reasons and require much attention for diagnosis. Thus, we will discuss appropriate diagnostic and therapeutic approach for secondary infection of umbilical keloid.

Title: Development of Generalized Pustular Psoriasis-like Eruptions and Alopecia Areata after Biologic Therapy in a Psoriasis Patient
Biography:
Department of Dermatology, Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine, 29, Saemunan-ro, Jongno-gu, Seoul, KoreaPsoriasis is an immune mediated chronic skin disease that afflicts the patient physically and emotionally. Currently there are many targeted drugs including tumor necrosis factor (TNF) inhibitors, T-cell inhibitors and interleukin (IL)-12/IL-23 inhibitors as effective substitutes for conventional systemic treatments. Although these drugs was proved to be relatively safe, various side effects have been reported.
Abstract:
Psoriasis is an immune mediated chronic skin disease that afflicts the patient physically and emotionally. Currently there are many targeted drugs including tumor necrosis factor (TNF) inhibitors, T-cell inhibitors and interleukin (IL)-12/IL-23 inhibitors as effective substitutes for conventional systemic treatments. Although these drugs was proved to be relatively safe, various side effects have been reported.
A 46-year-old female had a long-standing history of psoriasis that was inadequately controlled by phototherapy, systemic and topical treatment. Adalimumab (Humira®) was applied 5 times during two months. One week after fifth injection of adalimumab, her psoriatic lesions were aggravated and numerous scattered erythematous pustules were observed on whole body. Adalimumab was applied 4 times more, but there was no improvement, so she had received ustekinumab (Stelara®). Two weeks after administarion of ustekimumab, the patient presented with 3 alopecic patches on scalp. Trichoscopy of the affected area showed vellus hair and yellow dot. The patient continued to be treated with ustekinumab (Stelara®) and applied a topical 0.05% clobetasol-17-propionate (Dermovate® solution) for alopecia areata treatment, then she experienced improvement of psoriatic lesions and hair regrowth. We report this patient as a case of rare side effects following treatment with biologic agents.

Title: Title: Squamous Cell Carcinoma Presenting as Cellulitis
Biography:
Department of Dermatology, Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine, 29, Saemunan-ro, Jongno-gu, Seoul, Korea.In general, skin squamous cell carcinoma (SCC) presents as papules or plaques with erythematous or pigmented appearance that may ulcerate the skin. There are few reports from literature that SCC presents as skin cellulitis. By knowing the unusual presentations of SCC and diagnosing SCC in the early stage, advanced metastasis of the disease can be prevented and good prognosis with modest mean survival rate can be achieved.
