Tuberous sclerosis is a systemic disorder of hamartoma format on includes facial angiofibromas, subungal fibromas, hypomelanic maciles Shagreens patches. The earliest skin manifestation of tuberous sileiule, but it may appear later. We present a case of fibrous plaqu a recognized skin signs. Forehead plaque can be the earliest skin near in many organs. Skin involvement less forehead fibrous plaques, and vsis is usually hypornelanotic inacipearing before any of these more festation of tuberous sclerosis. Its presence may lead to early diagnosis and appropriate genetic couise hng hut may be a poor prognostic sign.

Oil granuloma is a foreignbody reaction which occurs after injection of lipid usually for cosmetic or therapeutic reasons. I present a case of eyelid oil granuloma caused by accidental high pressure injury in a 39-year-old man. The patient had a 2 x 0.5cm sized, firm, normardear subcutaneous nodule on the Rt. upper eyelid. Histopathologic examination showed a characteris swiss-cheese appearance. Eyelid oil granuloma caused by high pressure injury is very rare and my case is the first described in Korean medical literatures.

To elucidate the significance of the nesidiodysplasia of pancreas, histological re-evaluation and immunohistochemical studies for insulin, glucagon and somatostatin were done on 16 consecutive cases (5 premature babies, 2 stillborns, 5 infants and 3 adults) in which paraffin blocks of the pancreas were available. Only one infant was hypoglycemic. All 16 pancreases showed changes of nesidiodysplasia which appeared immunohistochemically to have isulin, glucagon and /or somatostatin. The histologic patterns of nesidiodysplasia included ductoendocrine proliferation, endocrine cell dysplasia, adenomatosis, septal islet, islket cell hypertrophy and islet hypertrophy. All the patterns of nesidiodysplasia except for the adenomatosis were seen in premature babies, infants, stillborns and adults with or without hypoglycemia. The adenomatosis was found only in the hypoglycemic infant. The result suggests that all patterns of nesidiodysplasia of other than the adenomatosis does not imply the pathologic basis of hypoglycemia.

We have experienced a case of 13 ring chromosome in a 40-month-old girl who demonstrated psychomotor retardation with delayed speech, growth retardation, hearing loss(left), microcephaly, trigonocephaly with flat occiput, hypertelorism, epicanthal folds, microophthalmia, broad prominamt nasal bridge, high arched palate, micrognathia, large auricles and other anomalies. Cytogenetic studies of peripheral blood lymphocytes with differential staining of chromosomes revealed 46, XX, r13. Her parents' karyotypes were normal. We reported the case with the review of the associated literatures.

Giant basal cell carcinoma(BCC) is a clinical expression of a large-sized BCC, which can cause extensive local invasion and disfigurement and have a particular capacity for metastasis. In the development of this large tumor, several risk factors including patient neglect, aggressive histological features and long duration, are identified. We have observed a very large BCC on the forehead of anlderly man for more than 4 years. He had been suffering from psychiatric disease for a long time, and patient neglect due to this problem played a crucial role in the development of this giant BCC.

PURPOSE: In this study we investigated the histopathologic characteristics of conjunctivochalasis and its association with lymphangiectasis using impression cytology and conjunctival excisional biopsy in patients with conjunctivochalasis. METHODS: This prospective study included 14 outpatients diagnosed with conjunctivochalasis, and who had excisional biopsies performed between March 1, 2012 and November 30, 2012. Preoperative slit-lamp examination, dry eye diagnostic test and impression cytology were also performed. For histological analysis, conjunctival sections were stained with hematoxylin and eosin (H&E), Verhoeff-van Gieson (VVG) elastic staining, and monoclonal antibody D2-40, a lymphatic endothelial marker. RESULTS: Tear break-up time and Schirmer's value were decreased in patients with conjunctivochalasis. Impression cytology showed a decrease in goblet cell density and an increase in nucleoplasmic/cytoplasmic ratio. The patients' conjunctival tissues exhibited an infiltration increase of chronic inflammatory cells on H&E stain, and a decrease in collagen density with degeneration of elastic fibers on VVG stain compared to tissues from the control subjects. D2-40 immunohistochemistry revealed the dilated subconjunctival lymphatics in patients with conjunctivochalasis. CONCLUSIONS: This study suggests that the characteristic histopathological features of conjunctivochalasis include dilated lymphatic vessels as well as decreased goblet cell and collagen densities with degeneration of elastic fibers.

We present a patient who developed granuloma in a previous herpes zoster scar (post-zoster granuloma). The development of granuloma in healed herpes zoster lesions may represent an atypical delayed hypersensitivity reaction to viral antigens or tissue antigens altered by the virus. To our knowledge, this is the first case reported in Korean literature.

Neurofibrosarcoma is the most common malignant change in patients with neurofibromatosis. But the incidence of neurofibrosarcoma arising from cutaneous neurofibroma is very low. We report two cases of neurofibrosarcoma arising from cutaneous neurofibroma in patients with neurofibromatosis showing typical clinical manifestations.

BACKGROUND: Cord blood transplantation has generated much enthusiasm because of the low incidence of GVHD(graft-versus-host disease), even in HLA(Human Leukocyte Antigen) mismatched situations, owing to intrinsic defects in mature T cell functions, and human cord blood is a constantly and easily obtainable source for hematopoietic stem cell. This study was undertaken to elucidate the possible mechanisms of low GVHD incidence observed when cord blood is used for stem cell transplantation. Based on current knowledge of the phenotypic correlates with functional subtypes of peripheral blood lymphocytes, we evaluated lymphocyte subpopulation in cord blood. METHODS: The 25 cord blood and 20 peripheral blood of adult control were included in this study. Monoclonal antibodies(MAb) conjugated with fluorescein-isothiocynate(FITC), phycoerythrin(PE) were used in this study. Heparinized whole blood was stained with mAbs using the whole blood lysis method. We used FACScan flow cytometer with argon laser tuned at 488 nm. Analysis was done by either Simulset or lysis II research software. RESULT: 1) The means of WBC and lymphocyte content were higher in cord blood than in adult blood(p<0.05). 2) The overall percentages of cord blood T(CD3+) cells, B(CD19+) cells, NK(natural killer)(CD16+/CD56+) cells were not different from adult controls. 3) The CD4+ : CD8+ ratio of cord blood was higher than thar of adult controls(2.7 in cord bloods versus 1.8 in adults). 4) The majority of the cord blood cells, both CD4+ and CD8+, co-expressed the CD45RA+ (naive) molecule. 5) The CD57, an antigen present on a subpopulation of NK cells, is absent in cord blood. CONCLUSION: We determined that cord blood contained mainly naive T lymphocytes to be predominantly suppressor cells. We found reduced alloproliferative, allostimulatory and allocytotoxic capacity of cord blood lymphocytes. Therefore, the GVHD may be less readily induced in cord blood transplantation, even in the face of HLA difference.

BACKGROUND: There is a long-standing controversy whether melanocytes in vitiligo of more than 1 year duration are actually lost or still present. Resolving this matter is essential in understanding the underlying pathology and for the development of the treatment. On previous immunohistochemical and ultrastructural studies of vitiligo lesions, damage of melanocyte and keratinocyte in early lesions were reported and complete absence of melanocyte in long standing lesions were known. OBJECTIVE: This study aimed to determine the existence of the differences in pathologic changes in melanocytes according to the duration of the lesion. METHODS: We investigated the vitiliginous skin samples from 31 patients with early(less than 1 year duration) vitiligo and 30 patients with long standing(l to 5 years duration) vitiligo under the electron microscopy. RESULTS: Multiple degenerative changes in melanocytes were observed in the early and long standing lesions. In long standing lesions, degeneration of melanocytes including pyknotic, in-dented nuclei, vacuolated cytoplasms and blunted dendrites were more pronounced than early lesions. Even in long standing lesions, definite or presumptive melanocytes were observed in 16(53.3%) of 30 cases. CONCLUSION: Our results suggest that the melanocytes of vitiligo lesions were damaged and that the percentage of degenerative changes increase in accordance with the duration of the lesion. However, in long standing lesions as well as in early lesions, some residual melanocytes can be observed ultrastructurally.
