BACKGROUND: Soil is one of the main habitat of fungi and important infection source of dermatophytosis. Objective: This study was performed to assess influence of dogs and horses to distribution of keratinophilic fungi (KPF) in soil. METHODS: We visited 3 dog shelters and 3 horse riding grounds in Daegu and Kyeongbuk province from September to November 2012 and examined isolation rates of fungi from 88 soil samples, 16 dogs and 16 horses. By the distance away from the animal shelters, soil samples were divided into 3 groups consist of near, 10 m and 100 m. Hair and scales from skin of the dogs and the horses were collected by Mackenzie's brush technique. RESULTS: Of the 88 soil samples examined, 35 (39.7%) yielded KPF and were all dermatophytes including Microsporum(M.) gypseum (34.1%) and Trichphyton(T.) ajelloi (5.6%). Isolation rates of KPF from the soil were observed in 79.3% of near, 40% of 10 m, and 0% of 100 m from animal shelters. Of the 16 samples from dogs, 6 (37.5%) yielded positive dermatophyte cultures and they were identified as M. canis 31.2% (5/16) and T. eboreum 6.2% (1/16). Of the 16 samples from horses, 1 (6.2%) yielded positive dermatophyte culture and it was T. eboreum. CONCLUSION: In this study, isolation rates of KPF especially M. gypseum and T. ajelloi were higher in the soil closer to the animal shelters. Soil nearby the dogs and the horses, the environment rich in keratinous material, is conducive for the growth of dermatophytes. But M. gypseum and T. ajelloi that rich in the soil were not isolated from skin of the dogs and the horses. Their pathogenicity might be low. We consider that if not human have immune deficiency or skin injury, they do not cause infection.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and highly aggressive hematopoietic malignancy which is derived from the precursors of plasmacytoid dendritic cells and is more infrequent in children than in adults. Formerly known as blastic NK-cell lymphoma or CD4+/CD56+ hematodermic neoplasm, the BPDCN is reclassified into the group of acute myeloid leukemia and related neoplasm by WHO in 2008. An 8-year old girl is being presented with bruise-like subcutaneous nodules with purpura on her right cheek from the performed biopsy. Histological examinations show sheet-like dense infiltrations of medium-sized lymphoid cells with irregular nuclei in the entire dermis. Immunohistochemical stainings of tumor cells were positive for CD4, CD56, LCA, TCL-1, TdT and focal positive for CD3, CD7, CD45RO and negative for CD20, CD30, CD34, EBV. The PET-CT scans indicate hot uptakes in the bone marrows which are suggestive of malignant infiltrations, and bone marrow biopsy findings are consistent with BPDCN of leukemic transformations. We present a rare case of BPDCN which affects the pediatric patient.

Intralymphatic histiocytosis (ILH) is a rare, chronic cutaneous condition characterized by the presence of dilated lymphatic vessels containing aggregates of mononuclear histiocytes within lumina. ILH presents with asymptomatic and poorly demarcated, erythematous plaques or livedo reticularis-like lesions, usually located on the extremities. ILH is often associated with rheumatoid arthritis, metal joint implants, and mastectomy scars of breast cancer patients, but its pathogenesis remains uncertain. A 69-year-old woman with osteoarthritis, who had a past history of cancer in the left breast, presented with asymptomatic, linear-shaped, scar-like erythematous plaques on the right elbow for a month. Approximately a month before her visit, she had been treated with an intraarticular corticosteroid injection on the right elbow in a local clinic. Histopathologic findings showed irregularly dilated vessels with intraluminal cells in the superficial and deep dermis. In double immunohistochemical staining with CD68/D2-40, endothelial cells lining the vessels were positive for D2-40 staining, which is a marker for lymphatic endothelial cells, and intraluminal cells were positive for CD68 staining, which is a marker for histiocytes. We present the findings of a patient with a rare condition of intralymphatic histiocytosis with scar-like morphology of the plaques.

Scedosporium apiospermum is an asexual state of Pseudallescheria boydii which has been isolated from soil, sewage, and decaying vegetation. It can cause cutaneous infections by traumatic implantation of the contaminant due to penetrating injury. This ubiquitous fungus cause not only mycetoma, but also infections of variety of body sites including the skin. The localized skin infection due to this organism is much rare than mycetoma. We report a case of cutaneous S. apiospermum infection occurred in 80-year-old male. The skin lesion was manifested by a 8.0 x 4.0 cm-sized erythematous plaque with pustules and crusts on the dorsum of right hand. The fungal culture from the biopsy specimen on Sabouraud's dextrose agar showed white to gray colored cottony colonies of S. apiospermum. The nucleotide sequence of internal transcribed spacer for clinical isolate was identical to that of S. apiospermum strain IHEM 23829. The patient was treated with oral fluconazole for 3 months.

Chromoblastomycosis is a chronic subcutaneous mycotic infections caused by dermatiaceous fungi. Clinically, chromoblastomycosis presents frequently with erythematous or nodular plaque. In Korea, 10 cases of chromoblastomycosis have been reported and Fonsecaea pedrosoi is the most common agent. A 61-year-old woman who was diagnosed as chronic inflammatory demyelinating polyneuropathy 3 years ago, and had been treated with systemic corticosteroids and azathioprine, presented with pruritic, scaly erythematous plaques on the right forearm for 3 years. She had no history of trauma. Histological examination showed pseudoepitheliomatous hyperplasia, mixed granulomatous inflammatory cell infiltrate and multinucleated giant cells with sclerotic cells in the dermis. Tissue culture showed slowly growing, dark brown, velvety colony. DNA was extracted from the cultured colonies and the DNA sequence of the internal transcribed spacer (ITS) region of the clinical sample was matched for that of Fonsecaea monophora. The patient was treated with local heat therapy and topical terbinafine application.
