Tubular apocrine adenoma and papillary eccrine adenoma are rare sweat gland neoplasms that appear as a small solitary lesion on the scalp or extremities, respectively. Although these lesions are thought to be distinct entities, there are enough similarities between them to group them under the term tubulopapillary hidradenoma or papillary tubular adenoma. We describe a case showing many tubular structures with papillary projection, syringocystadenoma-like structures, and eccrine hirocystoma-like structures in the axillary area. The term of papillary tubular adenoma or tubulopapillary hidradenoma may be prefered in this case.

Acquired tufted angioma is a benign, slowly progressive angioma with a typical histological pattern that was first described by Wilson-Jones in 1976. We report a case of acquired tufted angioma in a 19 year old female who had erythematous papules and plaques on the right thigh. Histopathological findings showed multiple capillary lobules in a cannonball arrangement scattered throughout dermis, which was diagnostic of acquired tufted angioma.

Subcutaneous granuloma annulare (SGA) is a rare, benign noninfectious histiocytic disease of unknown cause, characterized by necrobiosis of the connective tissue surrounded by infiltrates of histiocytes and lymphocytes. We report a case of SGA in a 49/12-year-old boy. The lesions were five nontender subcutaneous nodules in the parieto-occipital scalp, measuring 1.0 cm to 2.0 cm in diameter. Microscopical examination revealed variable stages of multiple necrobiotic areas, which showed central necrobiosis with palisading histiocytes, involving both the lower dermis and subcutaneous fatty tissue. Electron microscopic findings revealed many histiocytes in the necrobiotic areas with degenerating and necrotic collagen fibers as well as regenerating fibroblasts.

We report a rare case of subepithelial hematoma of the renal pelvis (AntopoI-Goldman Lesion). A 55-year-old women visited our hospital because of gross hematuria. Ultrasonogram showed a 4cm well-defined solid mass of the left renal pelvis. Intravenous pyelography revealed compression of the left upper pelvicocalyceal system by the mass with contrast filling within the mass. CT scan revealed Iobulated well defined mass in the left renal pelvis extending into renal parenchyme. A transitional cell carcinoma or renal cell carcinoma was suspected radiologically, and the patient underwent left total nephrectomy. In pathology, the lesion turned out to be a subepithelial hemaroma. In the differential diagnosis of renal malignancy, a subepithelial hematoma of the renal pelvis may be included.

Pityriasis lichenoides Chronica is a cutaneous disorder of unknown etiology and characterized pathologically by vasculitis and clinically by its marked chronicity and lack of specific treatment. Emollient-phototherapy is a recently introduced effective treatment for psoriasis. The authors treated 3 patients with pityriasis lichenoides chronica by the emollient-phototherapy technic with quite satisfactory results.

BACKGROUND: One of the most frequent cytogenetic abnormality in acute myeloid leukemia (AML) is t(8;21) (q22;q22), with rearrangement of the AML1 gene on chromosome 21q22 and the ETO gene on chromosome 8q22. In adult AML1/ETO-associated leukemia patients, chemotherapy alone results in cure rates that are comparable to or better than those achieved with allogenic bone marrow transplantation. Despite the relatively good prognosis of AML1/ETO fusion transcript, relapse of leukemia remains the most common cause of treatment failure. Monitoring minimal residual disease (MRD) in leukemia has two main aims : to assess the effectiveness of treatment and to detect early signs of relapse. Reverse transcription-polymerase chain reaction (RT-PCR)- based methods is the rapid and sensitive method in the identification of this molecular abnormality. The purpose of this study is to ensure the usefulness of the RT-PCR technique for detecting MRD in AML1/ETO-associated leukemia patients in remission and to establish the correlation of the serial detection of AML1/ETO fusion transcripts after complete remission and long-term outcome. METHODS: From the bone marrow aspirates of 25 AML1/ETO positive AML patients, serial detection of AML1/ETO fusion trascripts was performed using RT-PCR. RESULTS: AML1/ETO fusion transcripts were positive in 14 cases who did not show t(8;21). In serial assay, AML1/ETO fusion transcripts was positive in 9 cases and negative in 13 cases at 10 weeks after complete remission. AML1/ETO fusion transcripts (+) group has 107.4+/-18.2 months suvival and AML1/ETO fusion transcripts (-) group has 47.3+/-18.0 months survival. However, there is no significance (P=0.11). CONCLUSION: This study suggests that the early negative conversion of AML1/ETO fusion transcript may be the good prognostic predictor. The RT-PCR technique is useful for detecting minimal residual disease in leukemia patients in remission and it may improve the therapeutic strategy for leukemia.

Listeria grayi is a catalase-positive, non-spore forming, and glucose-fermenting Gram-positive rod. L. grayi is widely distributed in environments such as soil, water and fresh food. Human infection by L. grayi is very rare, and there have been no cases reported in Korea, and only two cases worldwide. Dermabacter hominis is a relatively new species belonging to the coryneform bacteria and is a component of the normal human skin flora. D. hominis is a non-motile, glucose-fermenting, Gram-positive rod that has similar biochemical characteristics to L. grayi. The authors of the present study report a case initially misidentified as L. grayi via a traditional morphological and biochemical identification method but that was subsequently confirmed as D. hominis using sequence analysis of 16S rRNA.

Foreign body impaction in airway is life-threatening as it can cause total airway obstruction. Such foreign bodies are removed under bronchoscopy in most patients. In some patients, however, the cardiopulmonary condition becomes unstable to undergo ventilating bronchoscopy under general anesthesia to remove the foreign body. In these conditions, extracorporeal membrane oxygenation (ECMO) can be adopted for cardiopulmonary support to stabilize the patient while removing the foreign body. ECMO supports tissue oxygenation and has been shown to improve survival of patients with adult respiratory distress syndrome. ECMO allows lungs to reserve their functions and decreases further lung injuries. The authors report one case of extensive tracheal inflammatory crust removed by ventilating bronchoscopy under tracheostomy and ECMO.

We describe a case of idiopathic CD4+ T-lymphocytopenia (ICL) in a 59-year-old patient who presented with various opportunistic infections. The patient was diagnosed with disseminated Mycobacterium avium infection, cytomegalovirus colitis and retinitis, and esophageal candidiasis. He was successfully treated with anti-mycobacterial drugs, ganciclovir, and fluconazole, respectively. However, the patient was diagnosed with primary central nervous system lymphoma, and then died of a Trichosporon beigelii sepsis during the 2nd cycle of systemic chemotherapy.
