We report a case of subcutaneous panniculitic T-cell lymphoma (SPTCL) which occurred in a 10-year-old Korean girl. Her disease presented as multiple erythematous subcutaneous nodules on the right cheek, left chest, abdomen, left flank, both calves, and left shin with systemic symptoms. She had a protracted course of multiple erythematous subcutaneous nodules for 2 months often with spiking fever. Histopathologic findings for the subcutaneous nodules revealed lobular panniculitis-like findings composed of atypical small, bland lymphocytes and histiocytes. Characteristically, atypical lymphocytes rimmed individual fat cells in a lace-like pattern and some histiocytes occasionally phagocytosed WBCs. Bone marrow findings revealed increased phagocytic histiocytes with engulfed hematopoietic cell. The immunophenotypic studies showed CD45RO (UCHLl)+, CD20-, CD4-, CD8+ and CD56+ (focal), lysozyme+, CD45 (LCA)+ and EBV-. She received three cycles of high-dose cyclophosphamide, adriamycin, vincristine, prednisolone (CHOP) and methotrexate, intrathecal methotrexate and one cycle of fludarabine, mitoxantrone and dexamethasone (FND) chemotherapy. She died of acute renal failure during multiple chemotherapy.

Crescentic glomerulonephritis in rheumatoid arthritis is described recently with increasing frequency. It can occur directly as a manifestation of rheumatoid arthritis or may be a reaction to drugs such as D-penicillamine and bucillamine. We report a case of crescentic glomerulonephritis in a 46-year-old woman with rheumatoid arthritis for 20 years who had been treated intermittently with herb medicine or nonsteroidal anti-inflammatory drugs (NSAIDS). Light microscopic examination showed severe focal segmental and global necrotizing glomerulonephritis with crescent formation in 50% of the glomeruli. Immunofluorescent study revealed scanty amount of mesangial granular deposits of IgA, IgM, C3 and fibrinogen in a diffuse pattern.

Bullae and sweat gland necrosis have been often described in patients with mental ges, whieh commonly alanifested as erythematous or vesicobullaus lesions on pressure sites. Histopathologically, the aecrosis of sweat glands is a characteristic 6nding. Generalized and/or loca1 tlssue bypoxia due to prolonged ieamobihxation may have resulted in these clinical and histopakological manifestations. To date, we have experielwed 15 cases with bulla and sweat gland necrosis. On admission, about half the patients had carbon monoxide poisoning, and the remainders had alcohol overdosage, drug inioxication, and others. A11 our patients had menfal changes caused by carbon wonoxide poisening, aleohol intoxication, and others. Abrupt erythematous swelling and/or vesicobullous lesione affected pressure sites in all patients. Three patietns had erythematoias lesiqms on non-pressure sites simuhtaneously. Histopathologic examinatians of 12 biopsy specimes showed the necrosis of the epidermis, intra- or sub-epidermal bulla, and/or sweat gland necrosis.

Cerebral aspergillosis is a rare condition that affects primarily the immunocompromised host. Most of cerebral aspergillosis is developed by hematogenous dissemination from extracranial foci, but aspergillosis of sino-nasal origin rarely affects the CNS. In case 1, wel symptom of tumor recurrence was unilateral numbness of the chin. A 65-year-old male was admitted because of paresthesia around the left chin and left lower lip. Neurologic examination revealed hypesthesia on the left side of chin, lower lip and buccal mucous mem-brane. Bone scan (Tc-99m MDP) showed focal hot uptakes on the left mandible and left first rib. Brain CT with bone window setting showed a focal osteolytic lesion in the bone marrow of the left mandibular canal without destruction of bone cortex. Both coronal T1 weighted image and axial T2 weighted image showed focal low signal intensities on the left ramus. The pathophysiologic mechanism could be understood by identification of the pathologic focus.

We have reviewed the 503 cases of benign skin tumors which were confirmed by histopathological study from January 1977 to July 1987 in the Dermatologic Department of Kyungpook National University Hospital. The result were summarized as follows . l. Among the total of 26,690 dermatologic out patients, 503 cases(1.9%) were diagnosed as having benign skin tumors. The number of benign skin tumors has shown a noticeable increase in the last several years. 2. The tumors were found mainly in ages ranging from the 2nd to 5th decade, most commonly in the 3rd decade(124 cases, 24.7%). 3. Aceording to Lever's elasaification, the tumors were divided into the following 7 groupa . tumors and cyets of the epidermis(35.2%), melanocytic tumors(16.5%), tumors of vaecular tissues(13.3%), tumora of epidermal appendages(11.1%), tumors of fibrous tissue(8.9%), tumors of neura.l tiasue(7.6%) and tumors of fatty, muscular and osseous tiseue(7.4%) in decreasing orders. 4. The 14 common tumors in order of frequency were as follows epidermal cyst (17.l% ),:melanocytic nevus(16.5%), neurofibroma(7.6%), congenital hemangioma(6.4%), nevus sebaceous(6.0%), lipoma(5.2%),seborrheic keratosis(4,8%), linear epidermal nevus(4.6%), steatocystoma mutiplex(2.8%), dermatofibroma(2.6%), hypertrophic scar and keloid.(2.6%), granuloma pyogenicum(2.4% ), keratoacanthoma(2.0%) and syringoma (2,0%). 5. The predilection sites of seborrheic keratosis, keratoacanthoma, syringoma and melanocytic nevus were the face, linear epidermal nevus, dermatofibroma and granuloma pyogenicum were located on the extremities. 6. The duration of tumors from the presumed time of onset to the first visit was within 1 year for epidermal cyst, keratoacanthoma and granuloma pyogenicum, over 10 years for nevus sebaceous, congenital emangioma and neurofibroma. 7. Diagnostic accuracy was higher in melanocytic nevus, congential hemangioma, nevus sebaceous and neurofibroma and lower in steatocystoma multiplex, dermatofibroma, keratoacanthoma, lipoma and epidermal cyst.

BACKGROUND: In renal transplantation, a good HLA-DR match Is associated with successive graft outcome. But due to a number of technical problems, reliable serological DR typing cannot always be obtained. To compare the serological DR typing with DRBI DNA typing, we tested 103 specimens that had been frozen after serological typing, by PCR-SSOP typing method. METHODS: Serological DR typing was performed by complement-dependent microlymphocytotoxicity technique using commercial antisera kits, and DNA gyp ins was performed by PCR-SSOP, using one of the methods recommended by 12th International Histocompatibility Workshop. DNA amplification was done by DRBAMP-A and DRBAMP-B primers, and hybridization by 18 oligonucleotides labelled with digoxigenin.. RESULTS: The concordance rate between serologic typing and DNA typing was 76.7%. Most (79.0%) of discordant results were due to serological blanks turning out to be definable antigens by DNA typing and these antigens consisted of mainly DR5 splits but none of DR1, DR2, or DR7. CONCLUSIONS: In spite of technical improvement, serological typing method often can not define the accurate HLA-DR type. It is thought that combining serological typing with DNA typing Is necessary to achieve a higher success rate of graft outcome.

Purpose: To report the availability of optical coherence tomography angiography (OCTA) when diagnosing type 1 and type 2 choroidal neovascularization (CNV) associated with age-related macular degeneration. Methods: We conducted a retrospective chart review of 63 eyes of 59 patients who visited the outpatient clinic from April 2018 to January 2020 with treatment-naïve type 1/2 CNV associated with age-related macular degeneration. The CNV was diagnosed through fluorescein angiography and indocyanine green angiography on the appearance of hyperfluorescence and leakage at the late phase. The CNV type was classified by location using OCT. These results were compared with those of automatic and manual segmentations via OCTA. Results: Of the 63 eyes, 45 eyes showed type 1 CNV and 18 eyes indicated type 2 CNV. Using the automatic segmented display of OCTA, type 1 CNV was identified in 29 of 45 eyes and type 2 CNV was confirmed in 17 of 18 eyes. In addition, when manual segmentation was performed, type 1 CNV was found in 41 of 45 eyes and type 2 CNV in 18 of 18 eyes. The sensitivity of diagnosis of type 1 CNV using only automatic segmentation in OCTA was 64.44%; the sensitivity increased to 91.11% when additional manual segmentation was performed (p < 0.001). For type 2 CNV, the sensitivity was 94.44% using automatic segmentation in OCTA and 100% with additional manual segmentation (p = 1.000). Conclusions Automatic segmentation of OCTA and OCT analyses enabled diagnosis of type 1 and type 2 CNV associated with age-related macular degeneration. The diagnosis accuracy or type 1 CNV improved significantly when manual segmentation was added.
