Pulmonary alveolar proteinosis (PAP) is a diffuse lung disease characterized by the accumulation of lipoproteins derived from surfactants in the distal air space. The lack of granulocyte macrophage colony-stimulating factor is believed to contribute to macrophage dysfunction and the impaired processing of surfactants. Because the prevalence of PAP in the general population is less than 1 in 200,000, and the typical age at presentation is 35 to 50 years, PAP is a very rare disease in children. To the best of our knowledge, there has been no Korean report on PAP in children. We describe here a patient who was diagnosed with PAP at the aged 15 years.

Seborrheic keratosis (SK) is one of the most common benign cutaneous tumors. However, it has been rarely reported that malignant tumors such as basal cell carcinoma (BCC), malignant melanoma and squamous cell carcinoma arising within SK. Seventy seven-year-old female presented with a brownish plaque on the left posterior thigh that had been present for more than 20 years. The ulcerative lesion has developed on the verrucous surfaced brownish plaque over the last few years. Skin biopsy performed two site of plaque including the ulcerated lesion and the peripheral margin. The ulcerated lesion revealed proliferation of basaloid cells palisading throughout the epidermis, clefting between the epithelium and stroma suggesting BCC and the peripheral margin showed epidermal hyperkeratosis, acanthosis, papilomatosis and pseudo-horn cyst suggesting SK. A total excised lesion showed histologic continuity from SK to BCC. Immunohistochemical analysis revealed extensive staining of CK19 and overexpression of p53 at the ulcerated lesion compared with the peripheral margin. These features suggest BCC arising within SK. We report a rare case of SK undergone malignant change to BCC.
A case of cutaneous infection caused by Mycobacterium gordonae
( Chan-yang Lee ),( Ye-jin Lee ),( Hyung-jin Park ),( Hye-jin Ahn ),( Min Kyung Shin ),( Ki-heon Jeong ) 대한피부과학회 2018 대한피부과학회 학술발표대회집 Vol.70 No.1
Mycobacterium gordonae is a type of slow-growing nontuberculous mycobacterium that has been traditionally considered a non-pathogenic environmental mycobacterium, although it has caused some disease in humans. A 50-year-old man presented asymptomatic plaque that has been presented for 40 years on the right cheek. He reported the plaque had gradually grown in size. Physical examination revealed erythematous annular hyperkeratotic plaque, mesured 5 X 7 cm size. Histologic evaluation revealed epithelioid granulomas with a large number of lymphocytes and multinucleated giant cells in the dermis. Special stain with acid-fast stains was negative for bacteria and fungal culture of the lesion was negative. Laboratory test showed positive result for interferon gamma assay. Tuberculosis Skin Test showed induration of 20mm diameter, 48 hours after injection. Mycobacterial infection was suspected. TB/NTM genotyping by real-time PCR using PANA qPCRTM detect NTM infection. Further NTM sequence analysis of 16S rRNA and 23S rRNA confirmed M. gordonae infection. After diagnosis the patient was treated with isoniazid and rifampicin. At the 3 month of follow up, skin lesion had flattened and decreased in size and he reported no adverse drug reactions.
A case of tinea capitis caused by Microsporum canis in a 109-year-old woman
( Chan-yang Lee ),( Ye-jin Lee ),( Hyung-jin Park ),( Hye-jin Ahn ),( Min Kyung Shin ),( Mu-hyoung Lee ) 대한피부과학회 2018 대한피부과학회 학술발표대회집 Vol.70 No.1
Microsporum(M.) canis is a zoophilic dermatophyte that is often transmitted to humans from animals. It has become one of the major causative pathogens of tinea capitis. Tinea capitis caused by M. canis is rare in an elderly. A 109-year-old who is admitted in geriatric hospital developed skin lesion and hair loss on the scalp for several months. Her guardian showed the clinical photos of the patient presenting localized erythematous plaques and pustules with yellow crusts on the scalp. The guardian said the patient had no history of contact with animals and no other family history of fungal infection. The guardian collected hairs and scales from patients’ scalp lesion. A KOH examination showed numerous spores and hyphae in the sample. A fungal culture revealed M. canis. The patient was treated with topical antifungal ointment because the guardian refused to treat oral medication to the patient owing to poor general condition. The skin lesions almost improved 2 months after topical antifungal treatment. Herein we report a case of tinea capitis caused by M. canis in a 109-year-old woman in geriatric hospital.
A case of lymphangioma-like Kaposi sarcoma
( Chan-yang Lee ),( Ye-jin Lee ),( Hyung-jin Park ),( Hye-jin Ahn ),( Min Kyung Shin ),( Ki-heon Jeong ) 대한피부과학회 2018 대한피부과학회 학술발표대회집 Vol.70 No.1
Lymphangioma-like kaposi sarcoma (LLKS) is a rare histologic variant of kaposi sarcoma that can present as any of the 4 known clinical variants. LLKS is a vascular neoplasm that develops secondary to infection by human herpesvirus type 8 (HHV-8), which is also known as the kaposi sarcoma virus. Clinically, it can present with the usual manifestations, namely, patches, plaques, or nodules. A 85-year-old female presented with painful plaque on the both sole that first appeared 1 month ago. She reported the lesions had gradually increased in number and size. Physical examination revealed raised erythematous, oval plaques measuring 1 cm in diameter. She had hypertension and otherwise healthy. Skin biopsy from the right sole demonstrated an atypical vascular proliferation of spindle cells interanastamosing as lymphangioma-like pattern. Immunohistochemical evaluation showed that tumor proliferation was positive for the endothelial markers such as CD31 and CD34. A Genotyping by PCR confirmed HHV-8 infection. After diagnosed with LLKS the patient was referred to the plastic surgery department for surgical excision. We herein report a rare case of lymphangioma like kaposi sarcoma.
Study on Reflectance and NDVI of Aerial Images using a Fixed-Wing UAV “Ebee”
Kyung-Do Lee,Ye-Eun Lee,Chan-Won Park,Suk-Young Hong,Sang-Il Na 한국토양비료학회 2016 한국토양비료학회지 Vol.49 No.6
Recent technological advance in UAV (Unmanned Aerial Vehicle) technology offers new opportunities for assessing crop situation using UAV imagery. The objective of this study was to assess if reflectance and NDVI derived from consumer-grade cameras mounted on UAVs are useful for crop condition monitoring. This study was conducted using a fixed-wing UAV(Ebee) with Cannon S110 camera from March 2015 to March 2016 in the experiment field of National Institute of Agricultural Sciences. Results were compared with ground-based recordings obtained from consumer-grade cameras and ground multi-spectral sensors. The relationship between raw digital numbers (DNs) of UAV images and measured calibration tarp reflectance was quadratic. Surface (lawn grass, stairs, and soybean cultivation area) reflectance obtained from UAV images was not similar to reflectance measured by ground-based sensors. But NDVI based on UAV imagery was similar to NDVI calculated by ground-based sensors.
Sebaceous carcinoma on the nose
( Chan-yang Lee ),( Ye-jin Lee ),( Hyung-jin Park ),( Hye-jin Ahn ),( Ki-heon Jeong ),( Min Kyung Shin ) 대한피부과학회 2018 대한피부과학회 학술발표대회집 Vol.70 No.1
Sebaceous carcinoma is a rare aggressive malignant tumor that primarily occurs in the elderly. It is usually located on the eyelid margin, especially meibomian glands. About 25% of tumors occur in extraocular sites which commonly involve the head and neck area, rarely affect the trunk and extremities. A 86-year-old man visited our clinic with a 1.5 X 2.0 cm sized erythematous nodule on the nose that had developed 1 year ago. Histological examination revealed irregular and variable sized tumor lobules composed of basaloid cells and few sebocytes showing mitotic activities and cytological atypia. Immunohistochemical analysis of the tumor cells was positive for EMA and CK. After diagnosed with sebaceous carcinoma, the patient was referred to plastic surgery department for surgical excision. We here in reports a rare case of sebaceous carcinoma on the nose for educational purposes.
