A 18-month-old girl was seen because of an yellowish brown papular eruptions on the face, earlobes and neck of one year duration. A skin biopsy specimen revealed circumscribed cellular infiltrates composed of predorninantly pleornorphic histiocytes. Electron microscopy of biopsy material disclosed numerous worm like particles and coated vescles in limited area of the cell cytoplasm, consistent with the findinga described in benign cephalic histiocytosis. After six months of her first visit, the individual papules became flattened.

Congenital self-healing reticulohistiocytosis (CSHRH) is a rare Langerhans cell disorder usually showing spontaneous resolution within 3-4 months. By electron microscopy, the identification of Birbeck granules and laminated dense bodies in the infiltrated cells is mandatory for the diagnosis of CSHRH. However, in some reported cases, Birbeck granules could not be demonstrated and only cytoplasmic dense bodies were seen. If the lesion is more advanced, Birbeck granules are transformed to lysosomes, i.e., 'unique phagosomes', in which they are degraded. A 2-month-old Korean girl presented with congenital, numerous red-brown pigmented papules on the left side of trunk and upper extremity without systemic symptoms. A biopsy specimen demonstrated papillary dermis containing epidermotropic infiltrates of histiocytes with abundant eosinophilic cytoplasm. Some had kidney-shaped nuclei and PAS-positive cytoplasmic inclusions. Immunohistochemically, infiltrating cells expressed S-100 protein and ultrastructurally, no Birbeck granules but many dense laminated bodies and unique phagosomes were found. It was ten months since the skin lesions developed that they have started resolving.

The incidence of primary lung cancer is increasing in our country. This presentation is an attempt to correlate a useful diagnosis with radiological findings of primary lung cancer. Histologically proved 210 cases of primary lung cancer are as follow: Epidermoid Ca. 65%, Adeno Ca. 18%, Small cell Ca. 9.5%, Large cell Ca. 2%, Unclassified Ca. 3.3%, Mucoepidermoid Ca. 2.4%, Mixed Ca. 0.5%. 3. In smoking history; 91% of epidermoid Ca, 17%of small cell Ca. 30% of adeno Ca. has smoking history. 4. In mass size; Average diameter of mass was most was5.3cm. Hilar mass was seen in 48 cases. Hilar mass was most frequent finding in small cell Ca. and the peripheral mass in adeno Ca. 5. Cavitary lung Ca. was 26 cases (12.4%) and most cases had relative thick wall and its mean thickness was 3.6mm. 6. Coexistence of pulmonary tuberculosis and lung cancer was 22 cases (10.5%), and most common in epidermoid cell Ca. as 16 cases. 7. Other findings include metastasis to lymph node, bone and other organ, and pleural effusion.

We report the results of the clinical and histologic and radiologic findings of the 17 patients who visited our hospital for the removal of the breast implants. Their mean ages were 45.9 and they visited our hospital 11.4 years after their operation of the breast implantation. In the 8 cases of the 17 patients, the contractures were seen and masses were palpated in the 4 cases. We also could find 1 case of the infection and 1 case of the abscess. There were the cases of the granuloma, siliconoma, calcification too. We find the radiologic examination before the removal of the implants in the 11 cases and could find the finding of rupture at the 9 cases (14 implants) but we confirmed that the number of the ruptured implants were 7 postoperatively. We reinserted new implants in the 12 cases and used saline filled textured implants. the number of the patients who want to remove the silicone gel implants is increasing with the reports of the doubt on the safety of the silicone gel. But there were on clear evidences of harmful effects of the silicone gel at now. We have to study more and need more experiences to used the more exact information to the patients.

PURPOSE: Chronic lymphocytic leukemia (CLL) is the most common form of leukemia in western countries but it has been reported rarely in Korea. The purpose of this study was to evaluate the clinical characteristics, treatment responses and prognosis of the patients with CLL. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 17 patients with CLL diagnosed at the Catholic University of Taegu-Hyosung & Kyungpook National University Hospital from Jan. 1986 to Mar. 1996. RESULTS: There were 9 males and 8 females and the mean age was 55 years. The majority of patients had systemic symptoms (77%) and advanced clinical stage (Binet stage C, 70%) at the time of diagnosis. The bone marrow histology was reviewed in 13 cases and patients were subdivided into those with a diffuse (9cases) and nondiffuse (4cases) pattern of bone marrow histology. In patients with advanced clinical stage, diffuse pattern was predominated and showed poor survival. 14 patients were treated with chlorambucil/steroid or combination chemotherapy. Among the 13 evaluable patients, 1 (8%) achieved a complete response and 7 (54%) achieved partial responses, and median survival duration was 18months. 11 patients died after 2~18 months of follow-up and infection was the main cause of death. CONCLUSION: Poor prognostic factors, such as high blood lymphocyte counts, diffuse bone marrow involvement pattern & advanced clinical stage, are common in our patients at presentation & showed poor survival.
