The heterotopic and tissues may be divided into two categories: those that are found in the head and neck region, and those that arise elsewhere. The latter type is rare and most cases are found in the lungs of patients with neural tube defect, particularly anencephaly. Our report descrives anencephalic male infant with heterotopic glial nodules in both lungs. The largest nodule is 2x1.5x1 cm, locates in the lower lobe of the left lung, and has a round gray-white cut surface with cystic spaces. Microscopically, the nodules consist of irregularly arranged astrocytes and glial fibers, in which are embedded gland-like or cystically dilated bronchioles. The astrocytes and glial fibers are strongly positive for glial fibrillary acidic protein and show astrocytic filaments on electron microscopy. This will be an additional case supporting the amniotic fluid aspiration/implantation theory of pathogenetic mechanism of distal heerotopic glial tissue.

Following results were obtained from the light microscopic and stereomicroscopic observations of the breasts of rats treated with 9, 10-Dimethyl-1,2-Benzanthracene(DMBA). 1) Adenocarcinomas developed in 17 rats (24%) among 70 DMBA-treated rats. 2) Terminal and buds (TEB) were observed longer in DMBA-treated rats than in control group, but they finally disppeared 4 monthes after treatment. 3) Many hyperplastic alveolar nodules (HAN) developed in DMBA-treated rats. 4) There were no transitional lesions between TEB and adenocarcinoma or HAN and adenocarcinoma. 5) The number of lobules was decreased in DMBA-treated rats. On the other hand, terminal ducts were increased in number. These findings suggest that DMBA stimulate the regression of lobules and induce to form terminal ducts from which adenocarcinomas and HAN develop independently.

A 9-year-old Korean boy with lissencephaly was found dead at home. He had previously been diagnosed with lissencephaly that presented with infantile spasm on the basis of magnetic resonance imaging and electroencephalogram results. Antemortem chromosomal banding revealed a normal karyotype. A legal autopsy was requested to eliminate the possibility of neglect or abuse by his parents. The autopsy findings revealed type I lissencephaly with the associated microcephaly. No external wounds or decubitus ulcers were noted. Postmortem fluorescence in situ hybridization for the LIS1 locus and nucleotide sequence analysis of the whole coding regions of the LIS1 gene did not reveal any deletions. The antemortem and postmortem findings revealed that lissencephaly syndrome was associated with isolated lissencephaly sequence. External causes of death were excluded by the full autopsy and toxicology test results. Because patients with mental retardation are frequently victimized and suffer neglect or abuse, thorough external and internal examinations should be conducted at the time of autopsy.

The use of a tissue expander and implant is the simplest option for breast reconstruction after mastectomy. Use of a round dome-shaped prosthesis and the commonly used one-stage technique with a Becker type prosthesis, however, often produces an undesirable upper pole fullness. To overcome this and to achieve improved aesthetic results, we started using an anatomically-shaped expander and implant, as described by Maxwell, as a two-stage breast reconstruction. We reviewed the results of our 21 reconstructed breasts in 22 patients who were deemed suitable for reconstruction using this technique since January 1995. The most commonly used expander was 350cc (range 350-550cc) and an average of 4.2 inflations were required before replacing the expander with a permanent implant. All the expanders were placed in submuscular pockets and implant volume. The longest follow-up was 36 months. Few complications developed and most patients were satisfied with the results. We found that the anatomically-shaped expander and implant produced better aesthetic results compared to a done-shaped prosthesis.

The autoinfective filariform larva of Strongyloides stercoralis causes hyperinfection in immunosuppressed hosts. Here we report on the case of a male patient who was admitted to the emergency room at Gwangju Veterans Hospital with a complaint of dyspnea, and who was receiving corticosteroid therapy for asthma. Many slender larvae of S. stercoralis with a notched tail were detected in Papanicolaou stained sputum. They measured 269 +/- 21.2 micrometer in length and 11 +/- 0.6 micrometer in width. The esophagus extended nearly half of the body length. The larvae were identified putatively as autoinfective third-stage filariform larvae, and their presence was fatal. The autoinfective filariform larva of S. stercoralis has not been previously reported in Korea.
