We report two cases of ectopic epididymal ducts and efferent ductules in the testicular appendices (TAs) of adult men with normally descended testes. In both cases, a sessile TA was incidentally found at the upper pole of the right testis during the scrotal hydrocelectomy. Microscopically, a few closely arranged tubules were detected within the TA. In the first case, the tubules were lined with a pseudostratified columnar epithelium with numerous, long microvilli, and were surrounded by a smooth muscle coat. In contrast, in the second case, the tubules had a wavy luminal surface, because ciliated columnar cells alternated with groups of cuboidal cells. In both cases, strong CD10 immunoreactivity was observed in the luminal border of the lining epithelium. Surgical pathologists should be aware of the presence of both ectopic epididymal ducts and efferent ductules that can occur in TAs, in order to avoid misinterpretation as transected, functional reproductive structures.

461 cases of renal biopsy specimens were summerized correlated with their light microscopic and immunofluorescence findings, which obtained from Jan. 1981 to Jul. 1986 at Department of Pathology, Kyung Hee School of Medicine, The results were as follws: 1) The incidence of IgM nephropathy was about 5.8% of the primary glomerulopathy. 2) Sex distribution showed male preponderance with male: female ratio of 1.7:1. 3) Age distribution were 0-9 years 7.4%, 10-19 years 29.6%, 20-29 years 37.0%, 30-39 years 7.4%, 40-49 years 7.4% and 50-59 years 11.1%. 4) The clinical symptoms were gross hematuria 7.4%, microscopic hematuria 59.2%, proteinuria (nonnephrotic) 37.0%, nephrotic syndrome 55.5%, hypertension 7.8% and edema 59.2%. 5) 9 cases (33.3%) had past histories of upper respiratory infections. 6) The distributions of the light microscopic deagnosis were minimal histologic change 11 cases (40.7%), focal glomerulonephritis 7 cases (25.9%), measangial proliferative glomerulonephritis 5 cases (18.5%), focal and segmental glomerulosclerosis 1 case (3.7%) and poststreptococla glomerulonephritis 1 case (3.7%). 7) Immunofluorescence study showed significant diffuse mesangial granular deposits of IgM and C3 in all of the 27 cases. 8) It was demonstrated that in the patients with nephrotic syndrome, the prognosis for the patients with IgM deposition were less favorable than those without IgM deposition.

Bizarre parosteal osteochondromatous proliferation was first described in 1983, when Nora and his collegues reported 35 examples of a proliferative lesion involving bones of the hands and the feet. In 1993, Meneses reported 65 cases of this condition. A fourth of all the reported cases involved the long bones. It is important to identify the clinical, roentgenographic, and histologic characteristic to seperate it from other entities because it is a benign lesion with atypical microscopic features with a tendency to recur. Roentgenograms show a calcific mass attached to the underlying cortex having a broad base. Histologically, the lesion exhibites proliferative activity, irregular bony cartilaginous interfaces, and enlarged, bizarre, and binucleated chondrocytes. We reviewed the bone tumors, diagnosed in the KyungHee University Hospital, dated from 1984 to 1994. Five cases were revised to Nora's lesion, all of which were previously diagnosed as osteochondroma. The ages of the patients ranged from 12 to 57 years (median, 19 years), and all of them were males. Two cases involved the bones of hands and feet (metacarpal and talus), and 3 cases involved the long bones (humerus, fibula, and ulna). One lesion involving the humerus has a recurrence. No metastasis had been reported.

Xanthogranulomatous cholecystitis is a rare form of inflammatory disease of the gall bladder and was first described in 1970 by Christensen and Ishak as fibroxanthogranulomatous inflammation of the gall bladder. Recently authors experienced three cases of xanthogranulomatous cholecystitis, two of which were erroneously diagnosed as malignant tumor in preoperative clinical and radiological examinations. Grossly, the gallbladders were enlarged and the walls were thickened with yellowish granular necrotic areas ranging from a few millimeters to 1.0 cm in diameter. Microscopically, all of three cases showed diffuse infiltration of the foamy histiocytes containing bile pigments and mononuclear leukocytes associated with fibroblastic proliferation and foreign body reactions. The pathogenesis of the xanthogranulomatous cholecystitis is uncertain, but opinion favours an inflammatory response to extravasated bile probably, from ruptured Rokitanky-Aschoff sinuses. Three cases of xanthogranulomatous cholecystitis with brief review of literature are presented.

Angioimmunoblastic lymphadenopathy (AILD) is a systemic disease clinically characterized by fever, generalized lymphadenopathy, hepatosplenomegaly, polyclonal gamma-globulinemia and Cooms' positive hemolytic anemia. The lymph node in AILD reveals a polymorphic feature consisting of a proliferation of small vessels, immunoblasts and plasma cells and acidophilic interstitial material. Progression into immunoblastic sarcoma is reported as high 35% of the patient with AILD. Nathwani et al have observed not only malignant transformation of AILD in sequential tissue examination, but also the coexistence of AILD and immunoblastic lymphoma in the same lymph node or at different sites in the same patient. Multiple clusters or islands of compactly arranged large lymphoid cells constitute the initial histologic evidence of immunoblastic sarcoma. Immunoblastic sarcoma is a large cell lymphoma conceptually related to transformed T-and B-lymphocytes of the extrafollicular compartment of the immune system, which proignosis is poor. We have recently experienced a case of immuno blastic sarcoma arising in angioimmunoblastic lymphadenopathy in a 24-year-old woman. She had history of multiple enlarged lymph nodes in the inguinal, axilla and supraclavicular areas. Previous lymph node biopsies revealed reactive change. Six month later, right axillary lymph node biopsy reveled AILD with focal clusters of immunoblasts. Subsequent lymph node biopsy at the same site revealed diffuse immunoblasic sarcoma, B-cell type. A case presentation with histologic findings and a brief review of literature were done.

Black adenoma is known to be a rare variant of adrenal cortical adenoma containing characteristic abundant lipofuscin pigments in the cytoplasm. Almost all of them are nonfunctioning and only occasionally they are associated with Cushing's syndrome or primary hyperaldosteronism. We present two cases of black cortical adenoma of the adrenal gland associated with Cushing's syndrome in a 24-year-old woman and a 64-year-old man. This report dealt with clinical and pathologic presentation including ultrastructural identification of lipofuscin pigment.
