Lobular carcinoma of the male breast is very rare, because of the absence of lobules in the normal male breast. Herein, a case of lobular carcinoma of the male breast with cellular features of signet ring cells is described. A 57-year-old man presented with a left breast mass. Histologic examination showed classic invasive lobular carcinoma with in situ component. Most infiltrating tumor cells had a prominent signet ring cell appearance. The patient was phenotypically male and had fathered children. There was no history of predisposing factors to breast lesion, such as hormone use or gynecomastia.

Inflammatory pseudotumor of the urinary bladder is an unusual, benign mesenchymal proliferative lesion of the submucosal stroma easily mistaken for a malignant neoplasm clinically and histologically. We present a case and describe the clinical presentation and radiologic, histologic, histochemical, immunohistochemical, and ultrastructural findings. A 23-year old patient presented with sudden onset of gross painless hematuria for 3 months. There was no previous instrumentation or surgery involving the genitourinary tract. Cystoscopy revealed a large polypoid and ulcerated bladder mass. The lesion consisted of plump spindle shaped, fibroblast-like cells embedded in a myxoid stroma. Mitotic figures were negligible and the lesion showed encroachment on the superficial muscle bundles. The spindle cells were immunoreactive for vimentin and muscle specific actin. Immunohistochemical and ultrastructural findings revealed the fibroblastic-myofibroblastic nature of this lesion. Complete surgical excision by partial cystectomy was successful in eradicating the lesion. The findings are described with a discussion of the pathogenesis and review of the literature.

Localized enterocolic lymphocytic phlebitis is characterized by selective phlebitis involving the small to medium-sized veins and venules, infiltration exclusively by lymphocytes, and no other systemic vasculitis or inflammatory bowel disease. This vasculitis can be a rare cause of intestinal ischemia. We experienced a case of enterocolic lymphocytic phlebitis in a 72-year-old woman, who presented with abdominal pain and distension. The resected colon and terminal ileum showed striking lymphocytic phlebitis affecting the veins and venules of the bowel and mesentery which resulted in ischemic injury of the bowel. This vasculopathy was the only demonstrable cause of ischemia. Arteritis and arteriolitis was not found. There is no clinical or laboratory evidence or a history of extraintestinal vasculitis. The etiology of this clinicopathological entity has not been elucidated. Herein, we report the clinicopathological findings in this patient who presented with ischemic intestinal necrosis caused by localized intestinal lymphocytic phlebitis associated with thrombosis.

Proliferative activity of a malignant tumor is known to reflect its biological aggressiveness. Proliferating cell nuclear antigen (PCNA) is a marker of cellular proliferation, and silver-stained nucleolar organizer regions (AgNORs) have been shown to correlate with ploidy and proliferative activity of cells. In transitional cell carcinoma of the renal pelvis, the prognostic value of these markers has not been well defined. We studied PCNA expression and the AgNORs count in 22 transitional cell carcinoma of the renal pelvis to assess their prognostic significance compared with their cumulative survival rate, the stage of disease and histopathologic features of the tumors. An immunohistochemical method and a standard colloidal silver staining were used. The mean percentage of PCNA positivity (PCNA index) and the mean number of AgNORs per nucleus (AgNORs score) were determined. In a multivariable analysis, PCNA indexes were significantly associated with tumor stage (p=0.024), whereas AgNORs scores were not significantly associated with the stage or histopatholgic features of the tumors. Histologic grade was correlated to disease stage at a significant level (p=0.000). But there was a trend of low tumor PCNA-indices or AgNORs counts with survival advantage for patients, but this did not reach statistical significance. The results suggest that the fraction of PCNA positive nuclei would be useful for investigating the malignant potential of renal pelvic cancers, although their clinical use as markers of biologic behavior may be limited.

This study was designed to compare the educational needs and satisfactory about infant care of the mothers in the Post-partum Care Center for development of the educational program. The subjects for this study were 100 mothers in the Post-partum Care Center in Seoul and Buchon. The data were collected during the period from Feb. to March, 2000. The Educational Need and satisfactory for Infant Care was measured by questionnaire that has developed by researchers. The data were analysed by descriptive statistics, paired t-test using SPSS PC+ WIN.The results were as fellow; 1) The educational needs of the mothers in the Post-partum Care Center were high (mean=4.32). 2)The satisfactory of the mothers in the Post-partum Care Center of educational program of infant care were middle range (mean=3.60). 3) The educational needs of infant cares in the Post-partum Care Center were higher than satisfactory of the mothers in the Post- partum Care Center of educational program of infant care(t=7.71 p=.000). 4) The educational need by content was signs, symptoms and management of disorders(i.g. cyanosis, seizure, fever, etc.) were higher than general care of baby(i.g. feeding, diaper change etc.). In conclusion, when the infant caregiver in the Post-partum Care Center teaching the method of infant care to mother, there should be in consideration of educational need of mother. And its educational contents must be included of mental and emotional development and signs, symptoms and management of disorders.

Korean Journal of Pathology 1997;31(2):174-178
An ossifying fibromyxoid tumor of soft parts is a rare, recently described, fibro-osseous neoplasm of uncertain histogenesis. It occurs most frequently within the subcutis or skeletal muscle of the extremities. Its biologic behavior is generally regarded as benign with at worst a locally aggressive clinical course. But, atypical and malignant variants have been recently reported. Herein we report a case of a benign ossifying fibromyxoid tumor which occurred in the left upper back of 41-year-old man. The tumor is composed of uniformly round or polygonal cells arranged in cords or nests which are separated by myxoid and hyalinzed fibrous matrix and associated with irregular bony trabeculae. The tumor cells are strong positive for vimentin. Ultrastructural findings and a review of literatures are added.

A clear cell islet cell tumor of the pancreas is extremely rare and characterized by extensive clear cell components. Electron microscopic and immunohistochemical findings are essential to prove that the mass with clear cells is an unusual manifestation of an islet cell tumor. Herein, we report a case of clear cell islet cell tumor of a 54-year-old woman with abdominal pain. The tumor was composed of polygonal clear cells arranged in nests, trabeculae, and ribbon pattern with the extensively fibrous stroma. These tumor cells showed strong reactivity for chromogranin and weak reactivity for somatostatin and glucagon. An electron microscope revealed that the important contributing factor of the clear cytoplasmic change was mainly due to an accumulation of lipid droplets, coupled with cytoplasmic swelling in some areas. Some tumor cells showed many endosecretory granules ranging from 111 to 297nm in diameter. In the clinical and immunohistochemical findings these granules were consistent with somatostatin granules in morphology and size.
