BACKGROUND
Dendritic cells (DCs) play an important role in immune reactions. This study was designed to identify the distribution patterns of DCs and regulatory T-cells (Tregs) in cutaneous lymphomas.
METHODS
Immunohistochemistry was used to determine langerin expression on Langerhans cells, CD11b on inflammatory DCs, CD209 and CD11c on dermal DCs, CD303 on plasmacytic DCs, and Foxp3 on Tregs in 81 cases of cutaneous lymphomas.
RESULTS
Various DCs and Tregs were identified in most cutaneous lymphomas. Plasmacytic DCs, inflammatory DCs and Tregs were identified mainly in tumor areas, whereas dermal DCs were distributed both in the tumor and stromal areas. Among DCs, dermal DCs were most prominently identified in the cutaneous lymphomas not only in the tumor area but also in the stroma. The intense stromal infiltration of dermal DCs was consistent finding in T-cell lymphomas. Diffuse large B-cell lymphoma (DLBCL), not otherwise specified also showed intense stromal infiltration of dermal DCs, but stromal infiltration in DLBCL, leg type was relatively scant.
CONCLUSIONS
The results suggest that all types of DCs and Tregs are involved in cutaneous lymphoma tumor immunity. Among them dermal DCs may play a dominant role.

AbstractAbstract
Serratia marcescens is the most important member of the genus Serratia and causes opportunistic infections, particularly pneumonia and septicemia in patients with malignancy, renal failure (acute and chronic), and diabetes mellitus. The most common portals of entry are known to be, in descending order, lung, genitourinary tract, intravenous line, gastrointestinal tract, and skin. S. marcescens rarely causes skin infection because it does not normally colonize human skin. Only six cases of S. marcescens cellulitis were reported. Five of them were immunocompromised patients. We have experienced a case of skin abscess caused by S. marcescens, which was found in a 59-year-old woman. She was undergoing prior antibiotic treatment after insulinoma surgery. S. marcescens was isolated from the skin abscess as a sole organism. She was treated with appropriate antibiotics that exhibited sensitivities for the organism and cured without any complication. The authors report a case of S. marcescens infection on the skin of a 59-year-old woman and review the literature concerning this organism as a causative agent.

AbstractAbstract PDF
The dysplastic nevus is a rare form of melanocytic nevus in Korean people. During the past 5 years the authors experienced 5 cases in the St. Mary's Hospital and Kang Nam St. Mary's Hospital. The criteria and the histologic findings of dysplastic nevi are debated in the western literature. Clinically, all cases were greater than 5 mm in size with ill defined irregular borders and irregularly distributed pigmentation. Histopathologically, all cases showed numerous discrete individual nests of melanocytes located in the dermoepidermal junction and the papillary dermis and were characterized by extension of dermoepidermal component of the nevus at the "shoulder" beyond the dermal component of the nevus. There was no cytologic atypia of nevus cells in all cases. Our cases lacked personal or family history of malignant melanoma. Therefore, we believe our cases are nonfamilial, sporadic and benign nevi with no prognostic significance. A brief review of the literature and a discussion on the term "dysplastic" and clinicopathologic correlation are made.

AbstractAbstract PDF
The spindle and epithelioid cell nevus, is known also as Spitz's nevus or benign juvenile melanoma. The histologic picture of the lesion often closely resembles that of a malignant melanoma, but spindle and epithelioid cell nevus hehaves benignly. Criteria for accurate histological diagnosis of this nevus now exist. However, a difficult lesion occasionally brings one to the worrisome situation even now. We experienced four cases (three children and one adult) of spindle and epithelioid cell neveus with nodular or macular skin lesions. In children (7/F, 9/F, 4/M), all of the lesion show a solitary pinkish red or light brown nodular firm masses, 0.7 cm to 1.0 cm in greatest dimension, which are located at the left posterior thigh, posterior neck and right anterior neck region, respectively. In adult (36/F), the lesion shows a light brown, erythematous macule, 0.8 cm in greatest diameter, in the skin of the back. Microscopically, both spindle and epithelioid cells are found in all the four cases, but epithelioid cells predominate in children and spindle cells predominate in adult.
