Present study describes two rare spermatic cord sarcomas. The first case is leiomyosarcoma of a 56-year-old man with 3-years' history of slowly growing hard mass in the right inguinal area, measuring 8x6x5 cm. The second case is fibrosarcoma of a 39-year-old man with 3x2 cm painless right inguinal mass. Both cases underwent radical excision of mass and orchiectomy. Clinico-pathologic characteristics of spermatic cord sarcoma are discussed with literature review.

To evaluate the morphogenesis of the human thyroid, a histologic study was made based on 100 normal thyroids of human embryos and fetuses ranging in age from 4 to 42 weeks of gestation. The embryos were serially sectioned and fetuses were examinated as an individual organ. 1) The first sign of thyroid primordium was the spherical proliferation of median ventral pharyngeal wall at the 4th week of development. 2) At the 6th week of gestation, the thyroid differentiated into two lobes that were connected by an isthmus, and was on the way of migration to the definite position from the foramen cecum. 3) The developing thyroid consisted of two cell cords, solid nests or interconnecting complex pattern until 14th week of gestation, when the entire portion of thyroid was replaced by follicles of variable size. 4) At the 9th week, the first follicle was recognizable at the periphery of the gland. 5) At the 14th week, follicles were partly filled with faintly eosinophilic colloid. 6) After the 18th week of gestation, lobulation of the thyroid parenchyme was a prominent feature. 7) After the 24th week, large follicles with rich colloid content are distributed through both superificial and deep portions. And after the 34th week, maturation reached the general pattern of adult thyroid. 8) The ability of thyroglobulin synthesis which was confirmed by PAP method, was first recognized at the 10th week of gestation.

In 1929, Bailey first described an intracranial sarcomatous tumor as a term of perithelial sarcoma. The term of microgliomatosis was introduced by Benedek and Juba, 1941. In recent period, malignant lymphoma was widely used rather than many other terms such as reticulum cell sarcoma, malignant reticulosis, etc. An autopsy case of microgliomatosis was presented. She was a 33-year-old woman with headache, ataxia, memory disturbance, defecation and micturition difficulty. She was relatively well until 3 months earlier before admission. She visited first St. Vincent Hospital due to memory disturbance, and a tumor was found in her left frontal lobe by CT scanning of her brain. She was transferred to Kang Nam Sacred Heart Hospital for further evaluation of the tumor mass. She ws given steroid therapy and somewhat improved in her symptoms. By follow-up CT scannings, the tumor could not be found. Her general conditions were progressively deteriorated and died on 85th day of her admission. Brain limited autopsy was performed. The external features of her brain were grossly unremarkable. Cut surfaces revealed multiple ill-defined grayish white masses, especially on deep white matter of left frontal lobe, left cingulate gyrus and white matter together with medial side of basal ganglia. The definite size was not able to be measured, but the largest one in left frontal lobe was about 2.5cm in diameter. Microscopically, the tumors have many characteristics of microgliomatosis, such as perivascular arrangement of tumor cells and concentric reticulin condensation. These microscopic features were seen not only in grossly visible masses but also in other areas, almost all cerebral hemispheres. Literature review on microgliomatosis and a case report were done.

The epidermoid cyst of the testis is a rare benign lesion with a characteristic gross and microscopic appearances. This 25 year old male who had been previously diagnosed as Klinefelter's snydrome (47/XXY) had right orchiectomy due to hard testicular nodule for a presented malignant testicular tumor. Sectioning of the testis revealed a intraparenchy matous cystic lesion, 1.5 cm in diameter, filled with cheesy white material. Histologically, stratified squamous epithelium lined the cyst. The remaining testis showed advanced tubular sclerosis and Leydig cell hyperplasia. It is necessary to submit multiple sections to rule out other histologic elements in the cyst wall or the presence of a scar. Although epidermoid cyst occurring as a solitary testicullar nodule could be regarded as a stage in the development of a teratoma, they need to be distinguished from the complex differentiated teratomas because of a distinct difference in prognosis.

Conjoined twins show varying degree of conjoining in either facing or side-by-side fashion. Cephalothoracopagus janiceps is a prototype of facing anomaly in which the two bodies demonstrated a cross symmetry to the midline, that is axial symmetry. Interfacial and intersternal lines crossed at a right angle and no abnormality of situs was associated. Dicephalus dipus dibrachius is a case of side-by-side union, in which the bodies facing nearly the same direction were symmetrical to the middle sagittal plane. Abnormal situs of one was always associated. Other types of conjoined twins as thoracopagus lie between the two extremes of facing and side-by-side union. The three dimensional architectures of the organs in each type would be explained using cross sectional figures of skull, thorax and pelvis. Although the facing twins share the internal organs without fusion, the organs in the side-by-side component are fused with modification of the situs. We postulate sixteen pairs of situs and four manners of division for the explanation of the midline organs and the presence of a dominant co-twin. The splenic locations in a given cardiopulmonary situs are evaluated for the appraisal and applicability of these hypotheses.

Neurenteric cyst is an extremely rare developmental cyst of the central nervous system. It is lined withintestinal epithelium and is usually found in the subarachnoid space of the cervical and thoracic spine. We reporta case of intracranial neurenteric cyst in a 40-year-old man, and describe the MRI findings. This modality showeda large cyst, ventral to the pons and extending bilaterally to the cerebellopontine angles and craniovertebraljunction;its signal was hyperintense on both T-1and T2-weighted images and there is no enhancement on postcontrastT1-weighted images.

Authors report the first autopsy case of acquired immune deficiency syndrome in Korea. The patient was a 26 years old Korean male who died of respiratory failure due to mixed pulmonary infections. He had history of homosexual contacts with partners of both domestic and foreign nationalities. Initial presentation was unexplained fever for two months. Serological test and western blot test for anti-HIV were positive and T-cell subset analysis revealed T3/T4/T8 to be 73/8/67%. Pulmonary tuberculosis with mediastinal lymphadenopathy and esophagonadal fistula and oral candidiasis were presented. Respiratory infection progressed gradually and he died seven months after the initial symptom. Autopsy findings were generalized severe lymphoid cell depletion, especially of T-cell population and mixed pulmonary infections with Pneumocystis carinii and cytomegalovirus (CMV). The CMV infection involved lungs and adrenals. Oral candidiasis was also demonstrated.
