Thanatophoric dysplasia is the most common lethal congenital chondrodysplasia with characteristic features of narrow thorax, short rib, severe platyspondyly, short bowed limbs and skull deformity, etc. It is not a hereditary disorder and there is usually no family history of dysplasia. We experienced a case of thanatophoric dysplasia at 38 weeks of gestation with antenatal sonographic and abdominal radiographic findings of small thorax, short bowed extremities with surrounding thickened soft tissues and marked platyspondyly. Soon atter delivery, the baby died and post-mortem radiographs showed the characteristic findings of thanatophoric dysplasia.

Lipoma is one of the unusual benign breast neoplasms and usually manifests at fatty breast of women at the age of 40 to 60. We experienced a case of large breast lipoma nearly replacing the whole left breast parenchymal tissue with mammographic finding of well-defined radiolucent mass, sonographic finding of hyperechoic mass with disorganized echopattern and computerized tomographic finding of very low attenuation mass, characteristic to adipose tissue, in a young woman of her dense breast.

We present a case of angiographically-confirmed transverse and sigmoid sinus thrombosis, image with MR, in a 20 year old male with a history of otitis media and maxillary sinusitis. T1-weighted image demonstrated an isosignal intensity mass with tubular-shaped low signal intensity in right transverse and sigmoid sinus. The thrombus had high signal intensity on T2-weighted image. The signal intensity of the thrombus on Gd-DTPA enhanced T1-weighted image was unusually high similar to that of transverse sinus. Although dural sinus thrombosis has a non-specific MR signal intensity, findings of MRI in this case may serve as an aid in future evaluation of venous thrombosis.

Male Breast cancer is an uncommon disease with an incidence of I per cent of all breast cancers. Male breast cancer usually appears as a small mass with well-defined contour which is eccentrically located in relation to the nipple on mammogram. We report a case of breast cancer in a 51-year-old man with mammographic appearance of large hyperdense mass with nipple inversion and axillary lymphadenopathy, gray-scale sonographic finding of homogeneous solid mass and mu Itiple tumor vessels with in the mass on color Doppler ultrasound.

Mucocele of the appendix is uncomrnon and rarely diagnosed preoperatively. The malignant rountpart-i.e. mucinous cystadenocarcinoma--has the same grross appearance and many micro scopic features in cornmon wilhe the benign form. It rnay be associated with ovarian mucinous cystadenoma of strikingly similar microscopic appearence. A serious complication is a rupture of the mucoeele resulting in pseudomyxoma peritonei. Each case of benign and malignant mucocelr of the appendix falsely diagnosecl as an oovarian tumor before laparotxumy are presented wilh a brief rieview of the literatures.

We present herein a case of painless piezogenic pedal papules occurring on the both heels of 25-year-old female patient, Histopathologic findings showed normal adipose tissue surrounded by loose fibrous tissue in the nid-dermis and thickening of venous wall. Hyalinized thick collagen bundles were distributed below the herniated adipose tissue in the nodular pattern. Her parents, one brother and sister had the sarne clinical features.

T-cell lymphomas primarily involving subcutaneous tissue and minicking panniculitis have rarely been described. In addition, some cases may have been orviously reported as malignant histiocytosis. Some of the affected patients have developed a hemohagocytic syndrome. A 44-year-old wornan showed multiple, recurrent, ill-defined, sarble sized, erythematous, tender subcutnaeous nodules on the trunk and extremities. Histopathological findings levealed the infiltration of hyperchrorriatiatypical large lymphocytes and nurnerous beanbag-like cells in the subcutaneous fat. The infitrted cells were positively stained with Leucocyte common antigen, UCHL-1 antigen, Lysozyme, that ot with CD20. Bone marrow biopsy showed mild erythreid hyperplasia and erythorophagocytic. hitiocytes. These histopathological features were consistent with cutnaeous T cell lymphoma involvnig the subcutaneous tissue.

Testosterone therapy in high doses produces male infertility. There are reports that atrophy of the interstitial cells and decrease in testicular size occur in the rat after treatment with testosterone, and the azoospermia which resulted from testosterone therapy could be reversed by simultaneous treatment with HCG. This study was evaluated for 45 days to clarify microscopic changes in the testis. A total of 60 male mice, 30 BALB/C strain, aged 3-4 weeks and with an average body weight of l2 g and 30 BALB/C strain, aged 3 months and with an average body weight of 20 g, were divided into 2 groups; for one group treatment with testosterone propionate only and another group fur treatment with testosterone propionate and HCG. The results of histological structure were as follows: 1. Mature group, treated with testosterone propionate (0.25mg/g B.W.) daily, reduced Leydig cell numbers and showed germinal epithelium atrophy, and inhibited spermatogenesis. 2. Mature group, treated with testosterone propionate (0.25mg/g B.W.) daily and HCG (2.5 I.U./g B.W.) every 3 days, showed normal variation of interstitial cell, germinal epithelium and spermatogenesis. 3. Immature group, treated with testosterone propionate (0.25mg/g B.W.) daily, increased in numbers of Leydig cells slightly and showed tortuous tubules and spermatogenesis. 4. Immature group, treated with testosterone propionate (0.2.mg/g B.W.) daily and HCG (2.5 I.U./g B.W.) every 3 days, showed normal variation of interstitial cell, germinal epithelium and spermatogenesis.
