We report the first case of an angiomyomatous hamartoma (AH) of the popliteal lymph nodes (LNs) occurring in association with diffuse pigmented villonodular synovitis (PVNS) of the knee. AH is a rare benign vascular disease with a predisposition for the LNs of the inguinal region. Twenty-five cases of AH have been reported to date; however, the precise pathogenesis is still undetermined. In the present case, an open synovectomy revealed two of three popliteal LNs in close proximity to the extra-articular component of diffuse PVNS. These LNs demonstrated irregularly distributed thick-walled blood vessels in the hilum. These vessels extended into the medulla and cortex and were associated with haphazardly arranged smooth muscle cells in the sclerotic stroma. These findings are compatible with an AH. Our observations raise the possibility that AH of the popliteal LNs may represent an abnormal proliferative reaction against the inflammatory process caused by PVNS of the knee.

Limb-body wall complex, also known short umbilical cord syndrome and body stalk anomaly, is a complex set of disruptive abnormalities consisting of failure of ventral body wall to close, short umbilical cord, disruption of lateral body wall, distinctive scoliosis of spine, limb defects, facial defects and cranial defects. This disorder has similar findings to amnioitic band syndrome. but limb-body wall complex appears severe scoliosis of spine, herniation of internal organs, absent or short umbilical cord. Recently, we present a case of limb-body wall complex which found at 32+1 weeks. A case was diagnosed with ultrasonography, so we report a case of limb-body wall complex with brief review of literature.

Hypersensitivity pneumonitis (HP) is an immunologically-mediated disease resulting from repeated exposure to sensitizing agents, such as organic dusts or chemicals. Isocyanate is a volatile and highly reactive chemical that is extensively used in the manufacturing of automobiles, upholstery, and polyurethane foam. Occupational respiratory diseases associated with isocyanate, such as bronchial asthma, are well-known. It is thought that HP is one of the rare diseases induced by isocyanate with a very low frequency worldwide. We report a case of HP in an automobile painting sprayer which appeared to be associated with isocyanate.

Epithelioid hemangioendothelioma (EH) is a rare borderline malignant tumor which originating from vascular endothelial cells and occurs in many organs such as soft tissues, lung, liver and bone. But, pulmonary EH which simultaneously involves pleura and liver is very rare. In the present report, we describe an uncommon case of EH involving the lung, pleura and liver in a 26-year-old woman. Chest CT showed single nodule in right upper lobe with large amount of pleural effusion at ipsilateral side and abdominal CT multiple round low densities in liver. The EH was confirmed by microscopic analysis and immunohistochemical staining of CD34+ from open lung biopsy specimen.

OBJECTIVE: Recently some reports suggested substance P and CGRP might be important factors for inflammation and hyperalgesia. This study was performed to see whether substance P or CGRP containing nerve fibers might be changed by mustard oil-induced inflammation. METHODS: After injection of mustard oil(5%) into uterine lumen, the uteri were removed and examined with immunohistochemical methods for substance P and CGRP. RESULTS: In the normal uterus, most of the substance P- or CGRP-immunoreactive nerve fibers were observed along the vascular structure and some in the myometrium, only few in the endometrium. Mustard oil did not changed this pattern of nerve fiber distribution but after 48 hrs, the amount of substance P or CGRP immunoreactive nerve fibers were greatly reduced compared with the normal uterus. It is not clear whether the decrease of substance P and CGRP immunoreactive fibers in the uterus was resulted from the depletion of the neuropeptides in the nerve fibers or the retraction of nerve fibers. CONCLUSIONS: These results suggest that the inflammation should cause the change of nerve fibers included in the nociception. This change may attribute the generation of inflammation and inflammatory hyperalgesia.

BACKGROUNDS: This study investigated whether or not a polymorphism in the gene encoding the surfactant protein A(SP-A) has any bearing on the individual susceptibility to the development of chronic obstructive pulmonary disease(COPD) in a genetically homogenous Korean population. METHODS: The genotypes of 19 COPD patients and 20 healthy neonates as controls were tested using a polymerase chain reaction followed by restriction fragment length polymorphism analysis for the SP-A gene. RESULTS: The specific frequencies of the 6A2 and 6A18 alleles of SP-A1 and the 1A2 allele of SP-A2 were much higher in the COPD group than control group (p<0.05). However, the frequencies of the 6A3 and 6A4 alleles of SP-A1 and the 1A0 allele of SP-A2 in the COPD group were significantly lower than the control group. In the COPD group, the frequencies of the +50 locus genotypes GG of SP-A1 and the +9 locus genotypes CC of SP-A2 were 85.0% and 60.6%, respectively, and 19.7% and 24.8% in the control group, respectively. The frequencies of the polymorphic genotypes or alleles showed a statistically significant difference between the COPD group and the control group (P<0.05). CONCLUSION: A genetic polymorphism in SP-A is associated with the development of COPD in the Korean population.

BACKGROUND: Bacterial infections in diabetic patients are an important cause of increased morbidity and mortality. It has been reported that bacterial infections in diabetics showed more impaired PMN functions such as reduced PMN respiratory burst and decreased microbicidal activity in inflammed tissues. Also, apoptosis(programmed cell death) is postulated to be a key mechanism for neutrophil elimination. It is very important that PMN apoptosis keeps the balance from an area of inflammation. Actuallly, as little was known about PMN apoptosis and respiratory burst in diabetes, we investigated PMN apoptosis and hydrogen peroxide production after endotoxin exposure. METHODS: Peripheral venous blood samples were collected by routine venipuncture from healthy volunteers and diabetics to harvest neutrophils. We respectively measured the PMN apoptosis, the production of hydrogen peroxide, and the cell viability. RESULTS: Normal neutrophils showed a tendency to decreased apoptosis after endotoxin treatment. In patients with diabetes, PMN apoptosis was significantly decreased compared with healthy controls. In addition, the LPS-induced neutrophils in diabetics demonstrated more decreased apoptosis. However, the production of hydrogen peroxide was not different between groups. CONCLUSION: These observations suggest that the decreased PMN apoptosis in diabetics with endotoxin exposure may also affect the increased susceptibility and severity of infections.

Benign cystic teratoma is the common ovarian tumor, and the incidence reported about 20%. Malignant transformation of mature cystic teratoma of the ovary is rare, which can develop with an incidence of less than 2%. The most common malignant tumor arising in mature cystic teratoma is squamous cell carcinoma which account for 75-85%, but vary rare cases of anaplastic carcinoma arising from mature cystic teratoma has been reported all over the world and prognosis of this malignant tumor was poor. No case of anaplastic carcinoma has been reported before in Korea. We experienced a case of anaplastic carcinoma arising from mature cystic teratoma of the ovary and report our case with a brief review of literature.
