Malignant transformation of benign cystic teratomas of the ovary is rare, with an incidence rate of 1-3%. The most common malignancy associated with benign cystic teratoma of the ovary is squamous cell carcinoma, which represents 90% of malignant transformations, followed by adenocarcinoma and carcinoid. Primary malignant neuroectodermal tumor in a mature cystic teratoma is extremely rare and microscopically can be subclassified as differentiated, primitive, and anaplatic. We experienced a case of primitive neuroectodermal tumor (PNET) associated with mature cystic teratoma of the ovary in a 11-year-old girl. Grossly, the ovary was a unilocular cyst which contained sebum material and disclosed several large, yellow to gray-tan polypoid excresences attached to the inner cystic wall. Except a large, fish-flesh, soft mass, the other polypoid masses were covered with sebum and contained small pieces of cartilage and tooth, and microscopically represented as mature teratoma. The large, fish-flesh, soft mass disclosed sheets and lobules of closely packed small cells with thin fibrovascular septa, which frequently replacing and encroaching the mature cystic teratoma. The small tumor cells were uniform and made up of round to oval nuclei with coarse chromatin and prominent nucleoli, very similar to those of PNET of the central nervous system.

OBJECTIVE: To evaluate the effect of IL-10 on development of collagen-induced arthritis, on humoral and cellular immunity and on the endogenous production of IL-10 in DBA/1J mice. METHODS: DBA/1J mice were immunized with chicken type II collagen in Freund s complete adjuvant. Murine recombinant IL-10 was given intraperitoneally twice a week from the day of second immunization (week 3) in doses of 0.002ug, 0. 02ug and 0. 2ug for 3 different groups, respectively. Dexamethasone was injected in one group to suppress the arthritis development and this group was used as negative control group. Levels of anti-collagen antibodies, serum IL-10 and stimulation indices of splenic monocytes to collagen were measured at the end of study. RESULTS: The 0. 02ug IL-10 and 0. 2ug IL-10 treated groups developed earlier and more severe arthritis (week 6 and 8) compared to that of the control group while the 0. 002ug IL-10 group has shown similar course to the control group in terms of incidence and severity of arthritis, At week 10, all groups with or without IL-10 injections developed arthritis with similar degree of severity while dexamethasone group showed far less incidence and severity of arthritis. The serum levels of anti-collagen antibody, IL-10 and spleen monocyte stimulation indices to collagen antigen showed no difference among control group, IL-10 injected groups and dexamethasone injected group. CONCLUSION: This study shows IL-10 could worsen the arthritis in CIA with the dosage used in this study without significant influence on the level of anti-collagen antibodies or stimulation indices of spenic monocyte to collagen.

Low-grade endometrial stromal sarcoma (LGESS) with intravascular extension is very rare, with only 26 cases having been reported. We experienced a case of LGESS with inferior vena cava (IVC) extension. A 60-year-old female presented with left leg edema. She had a history of total hysterectomy, and was diagnosed of leiomyoma at that time. On imaging study, tumor masses were located around both common iliac veins (CIV), and within the CIV and IVC. The pelvic masses on both side and IVC mass were resected, and then the patient received adjuvant hormonal therapy and radiotherapy over the remnant pelvic masses. LGESS with IVC extension is difficult to distinguish from intravascular leiomyomatosis. LGESS is a malignant disease and commonly recurs, even in early stages. Accurate diagnosis, complete resection, proper adjuvant therapy and close follow-up are very important.

Bullous pemphigoid(BP) and herpes gestationis(HG) are subepidermal bullous diseases which show clinical and immunological similarities. Both diseases show immune deposits along the basement membrane zone and their autoantibodies bind a common antigenic site within the non-collagenous stretch of the 180 kDa BPAG2 ectodomain. Besides its association with pregnancy, HG has some characteristic features that distinguish it from BP. The serum of patients with HG often contains an IgG that avidly fixes complement, and showes IgG1 subclass predominance. We report here two cases of non-pregnant young women presenting clinical and histological features of bullous pemphigoid or herpes gestationis. The immunopathology, IgG subtyping and immunoblotting studies showed that the autoantibodies in the patients were the characteristic ones of herpes gestationis. The patients might be a subtype of BP that have characteristics of autoantibodies of HG patients.
