Angioleiomyoma(ALM) of the cavernous type is a rare subtype of leiomyomas arising from the smooth muscle of veins. ALM of this type invariably shows clinically and histopathologically distinctive features, compared with the classical solid or venous type. However, no case of ALM of this type has been yet reported in Korea although there have been several reported cases of other types. We herein present the case of a 39-year-old man with a 7-year history of a painless ALM of the cavernous type on his buttock with the histological features of markedly ectatic vascular channels and thin intervascular bundles of smooth muscles.

Open carpal tunnel release surgery has heen the gold standard method of treatment for who did not respond to conservative treatment and whose neurologic symptoms were progressive. However, open carpal tunnel release using a standard incision frequently associated with delayed return of hand function, residual scar tenderness and pillar pain. So, two new alternative methods such as endoscopic carpal tunnel release and limited incision technique have developed. To define the role of the limited two incision technique, we anaiyzed the postoperative functional results of 40 cases in 33 patients. The patients were divided in two groups. Group A was standard incision group (23 cases in 19 patients) and Group B was limited two incision group (l7 cases in 14 patients). The postoperative functional results were analyzed statistically using chi-square test at postoperative 3, 6, 9 and l2 weeks. There were no significant differences in reliet of numbness and paresthesias in both groups. There was a statistically significant difference in relief of scar tenderness and pillar pain at postoperative 3 and 6 weeks in Group B. There was no significant complication in both groups. We can conclude that the limited two incision technique of carpal tunnel release is a safe procedure which allows rapid return of hand functions with reduced incidence of scar tenderness in the early postoperative stages.

Fracture of the femoral neck occurred after internal fixation of intertrochanteric fracture of the femur is very rare and have been described previously in terms of stress fracture, stress-riser fracture, Youngs modulus fracture or iatrogenic fracture in the literature. This fracture documented about 20 cases in the English literature and usually occurred in elderly patients with osteoporosis and it always occur in the subcapital region. We report a case of subcapital stress fracture of the femur occurred after internal fixation with compression hip screw of intertrochanteric femur fracture.

Non-nasal T/NK-cell lymphoma(TNKCL) without nasal cavity invasion is a subtype of angiocentric T-cell lymphomas showing the biphenotype of the T-cell and NK-cell. This tumor is characterized by the absence of clonal rearrangement of the T-cell receptor gene, frequent association with Epstein- Barr virus(EBV), poor clinical course, and common extranodal invasion. Antiphospholipid syndrome (APS) is characterized by repetitive spontaneaus abortion, thrombocytopenia, thrombotic symptoms and the positivity to the antiphospholipid antibody. Our patient was a 35-year-old woman with skin lesion on her face. Previously, she had been diagnosed of APS. Histopathological, immunohistochemical and serologic studies could disclose EBV-associated non-nasal TNKCL.

BACKGROUND: A pathogenesis of skin-homing lymphoid cells in primary cutaneous T-eell lymphoma(CTCL) has not been elucidated, CLA(cutaneous lymphocyte-associated antigen) defined by HECA-452 monoclonal anfibody has been proposed as the novel skin-homing receptors of infiltrative lymphocytes in atopic dermatitis and graft-versus-host disease. Accordingly, CLA may be a determinant explaining about the skin-homing properties of lymphoid tumor cells in CTCL. OBJECTIVE: This study was conducted to investigate the immunohistochemical expression of CLA in the lesional tissue specimens of cutaneous lymphomas. METHODS: Immunohistochemicslly, we examined the expression of CLA, E-selectin, ICAM-1 and LFA-1 antigens in the tissue specimens taken from the skin lesions and lymph nodes of the 22 patients with cutaneous lymphomas and the 20 control subjects with non-cutaneous lymphomas. Results : 1. The expression rate of CLA was 40.9% in the skin specimens of cutaneous lymphomas. We could not fad any expression of CLA in non-cutaneous lymphomas. 2. CTCL showed a more frequent expression of CLA(80%) than cutaneous B-cell lymphomas (CBCL)(8.3%). We found more frequently CLA+ high endothelial venules in non-cutaneous lymphomas(40%) than in cutaneous lymphomas(9.1%). 3. CLA and E-selectin were more frequently expressed in primary CTCL(100%, 83.3%) than in secondary CTCL(50%, 0%). 4. The positivity to ICAM-1 and LFA-1 antigens was higher in primary cutaneous lymphomas (72.7%, 81.8%) than in secondary forms(9.1%, 9.1%). Conclusion : CLA and E-selectin may represent the pivotal skin-homing receptor of infiltrative tumor cells and vascular counter-receptor in primary CTCL, respectively. Also, ICAM-1 and LFA-1 may have a role in the primary cutaneous infiltration of lymphoma cells as the additional cofactors.

We herein present two cases of generalized pustular psoriasis(GPP) followed by acquired bullous diseases during antipsoriatic management. Although there were several reports de-scribing the coexistence of psoriasis vulgaris and autoimmune bullous diseases such as bullous pemphigoid or pemphigus vulgaris(PV), a coexistence of GPP and bullous disease was sparcely reported. In one patient, we could define atypical autoantigen which was distinct from the other known antigens in documented cases of bullous diseases. The other case was compatible with PV. The psoriatic lesions and bullous eruptions of the two patients cleared in several weeks after administration of cyclosporine.

BACKGROUND: Inflammatory bowel disease(IBD) such as ulcerative colitis or Croln's disease is often related with varied diseases including pyoderma gangrenosum, erythema nodosum, ankylosing arthritis and psoriasis. To date, however, a cIinical observation of IBD accompanied by psoriasis has been sparcely accomplished although an immunogenetic mechanism explaining a coexistence of IBD and psoriasis has been proposed. OBJECTIVE: We estimated the prevalence of IBD in patients with psoriasis in Korea and investigated the clinical characteristics of IBD accompanied by psoriasis. METHODS: 92 psoriatic patients and 389 non-psoriatic control subjects were enrolled in this study. Colonoscopic biopsy and barium series were performed in 47 psoriatic patients and 110 control subjects showing irritative intestinal symptoms. RESULTS: 1. The prevalence of IBD in psoriatic patients(14.1%) was significantly greater than in the control group(1.0%). 2. In the temporal relationship, psoriasis developed several years prior to the onset of IBD in 84.6% of psoriatic patients. 3. The frequency of arthropathies in the psoriatic patients possessing IBD(84.6%) was significantly higher than that of non-psariatic counterparts with IBD(25.0%) or that of psoriatics without lBD(2.5%), 4. The psoriatir. patients with IBD demonstrated much more frequently diffuse colonal extension than in non-psoriatic subjects with IBD. CONCLUSION: Our findings of an increased prevalence of IBD in the psoriatic population present further evidence of an association between IBD and psoriasis. In the psoriatic patients showing acute or chronic gastrointestinal symptoms, colonoseopic evaluation might be mandatory for the evaluation of IBD.

BACKGROUND AND OBJECTIVES: We investigated the clinical value of additional von Kossa staining in thyroid nodules with "suspicious for malignancy" on cytology. MATERIALS AND METHODS: From March 2010 to November 2010, 55 patients with 55 nodules which were diagnosed as "suspicious for malignancy" on cytology and had microcalcifications on ultrasound (US) underwent surgery and made up our final study population. We evaluated the role of the von Kossa stain as a preoperative diagnostic factor for thyroid cancer using histopathology as the "gold standard". Diagnostic performances were calculated of the presence of psammoma bodies on both cytology and the von Kossa staining and of US in predicting thyroid cancers. RESULTS: Of 55 nodules with microcalcifications on US and "suspicious for malignancy" on cytology, 53 (96.4%) were malignant and 2 (3.6%) were benign on histopathology. All pathologically benign nodules were negative on the von Kossa stain. The sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) of the von Kossa stain were 28.3%, 100%, 30.9%, 100%, and 5% for diagnosis, respectively. CONCLUSION: Von Kossa staining can be a valuable diagnostic tool in a thyroid nodule with "suspicious for malignancy" on cytology and microcalcifications on US, objectively.

Ossifications of the ligamentum flavum(OLF) and the posterior longitudinal ligament(OPLL) are uncommon clinical entities as a cause of the progressive compression myelopathy or radiculopathy. Although there are considerable literatures concerning OPLL or OLF in cervical and thoracic spine, there are only a few references about OPLL or OLF in the lumbar spine. OLF and OPLL have been reported that they may lead to severe complication only with a minor trauma or even without trauma, such as paraplegia. The authors have experienced 2 cases of OLF accompanied by OPLL In the lumbar spine, who were treated with decompressive laminectomy and excision of ossified ligaments. For its rarity of OLF and OPLL in the lumbar region, we report here with review of literature.
