The authors analysed 261 cases of mycoplasmal pneumonia in children who were admitted to the pediatric department of Seoul Adventist Hospital between July 1986 and June 1991. The result obtained were as follows; 1) Yearly distribution of the cases showed high in 1987 and 1991, but no significant difference was noted in seasonally or monthly distribution. 2) The peak incidence of age was between 2 and 6 years of age, and the sex ratio of boy to girl was 1.1:1. 3) pulmonary manifestations were asthma in 21 cases (8.0%), atelectasis in 5 cases (1.9%), emphysema in 3 cases (1.2%), pleural effusion in 16 cases (6.1%), otitis media in 4 cases (1.2%) and sinusitis in 9 cases (3.4%). 4) Extrapulmonary complication were hepatitis in 53 cases (20.3%), skin rash in 9 cases (2.4%), proteinuria in 6 cases (2.3%), and hematuria in 4 cases (1.5%). 5) On the chest X-ray examination, the most common type of pneumonia was interstitial pneumonia (94 cases, 39.8%), and unilateral involvement was common (85.6%), and the most common involvement was right lower lobe (83 cases, 41.4%). 6) The relationship between the type of pneumonia and cold agglutinini titer, and between the type of pneumonia and Mycoplasma antibody titer were not found (P>0.05). 7) In the 16 cases of pleural effusion, The type of pneumonia was lobar, lobular (9 cases), bronchopneumonia (7 cases), and interstitial type was not present. The site of pneumonia was left (6 cases), right (9 cases), and 1 case showed bilatrality. The extent of pleural effusion was mild (10 cases), moderate (3 cases), and severe (3 cases). The result of pleural fluid exam in severe cases was all exudate. 8) The mean duration of admission was most common from 6 to 10 days. the mean duration of admission by the type of pneumonia was lobar, lobar (10.71+/-3.40), interstitial (8.78+/-2.14), and bronchopneumonia (8.83+/-2.47). 9) Both mycoplasma antibody test and cold agglutinin test were carried out in 185 cases and sensitivity of mycoplasma antibody test was 55.1%.

Aplasia cutis congenita (ACC) is an uncommon condition which is characterized by congenital, localized or widespread absence of skin or scar formation. Lesions can be multiple and may occur on any body surface, although they are mostly seen on the scalp as a solitary lesion. ACC is most often a benign isolated defect; but it can be associated with other physical anomalies or malformation syndromes. Adams-Oliver syndrome is a distinct subtype in which distal limb reduction is found in association with a solitary scalp defect. There is no single underlying cause of ACC; it may reflect a disruption of intrauterine skin development. A 25 day-old boy was referred to our clinic with a thick hemorrhagic crust, and a surrounding hairless atrophic scar on the midline over the skull vertex. He also had hypoplasia of the left 2nd to 5th toes since birth. The rest of the physical examination as well as an ultrasound examination of the brain were normal. Herein we report a rare case of ACC of the scalp accompanied by distal limb hypoplasia, Adamson-Oliver syndrome.

BACKGROUND: CD34 is expressed by early hematopoietic (myeloid & lymphoid) progenitor cells, endothelial cells, and bone marrow stromal cells. Recent studies have suggested that the expression of the hematopoietic antigen CD34 is predictive of outcome. But the functional importance of CD34 antigen has not yet been fully elucidated, and CD34 antigen has not yet been included in the routine immunophenotyping panel. We designed this experiment to evaluate the significance of including CD34 antigen in the routine immunophenotyping panel. MATERIALS AND METHODS: We have included CD34 antigen in the immunophenotyping panel from 1994 to 1997. Seventy eight patients with acute leukemia and 7 patients with chronic leukemia and CML-blast crisis were analyzed by direct immunofluorescence using monoclonal antibodies. RESULTS: CD34 was positive in 64% (50/78) of cases with acute leukemia and 100% (3/3) of cases with CML-blast crisis, but negative in 100% (4/4) of cases with chronic lymphocytic leukemia. Seventeen (63%) of 27 patients that belonged to AML FAB subtype M0, M1, M2, M4, M5, M7 were CD34-positive, but all of the 9 patients (100%) that belonged to AML FAB M3 were CD34-negative. Thirty-one patients of CD34-positive non-T-ALL belonged to immunologic group II, III, or IV, and all 2 patients of CD34-positive T-ALL belonged to immunologic group I. There are no significant correlations of CD34 with the remission rate and the survival rate of acute leukemia. CONCLUSIONS: CD34 facilitates the rapid diagnosis of acute promyelocytic leukemia (APL) different from the other AML subtypes in clinical course and therapeutic plan. It is also helpful for the immunologic grouping of ALL, and differentiation of chronic leukemia from CML-blast crisis or acute leukemia. We concluded that it is desirable to include CD34 in the routine immunophenotyping panel.

Acquired brachial cutaneous dyschromatosis (ABCD) is an acquired disorder of pigmentary change that presents as chronic, asymptomatic, geographic-shaped, gray-brown patches, consisting of mixed hyper and hypopigmented macules on the dorsal aspect of the forearms. We report a case of a 40-year-old male who presented with asymptomatic, multiple brown-colored macules on the outer aspects of both arms. He had no history of hypertension and had never taken angiotensin converting enzyme inhibitors. He also denied chronic sun exposure history. Histologic examination demonstrated epidermal atrophy, increased basal layer pigmentation, and several telangiectatic vessels in the upper dermis. Solar elastosis was not remarkable. The patient's clinical and histopathologic features were consistent with a diagnosis of ABCD. Poikiloderma of Civatte, melasma, acquired bilateral telangiectatic macules and other pigmentary disorders should be considered in the differential diagnosis of ABCD. Herein, we report a case of ABCD in a middle-aged male without hypertension and medication.

Orofacial granulomatosis (OFG) is a rare chronic granulomatous disease of oral mucosa and maxillofacial region that clinically presents recurrent or persistent orofacial swelling. OFG may exist as an integration of the spectrum of various disorders, including Melkersson-Rosenthal syndrome, granulomatous cheilitis, Crohn’s disease, sarcoidosis, infectious diseases and delayed hypersensitivity reaction to food additives, dental materials. Precise etiology is not yet to be elucidated. Herein, we report two rare cases of orofacial granulomatosis who presented similar clinical manifestation of lip swelling but was diagnosed as a sarcoidosis and as a granulomatous cheilitis.
