Benign fibrous histiocytoma is a tumor composed of a mixture of fibroblastic and histiocytic cells that are often arranged in a cartwheel or storiform pattern and accompanied by varying number of inflammatory cells, foam cells, and siderophages. Benign fibrous histiocytoma represents one of the common soft tissue tumors with most cases presenting in the skin. The common sites of incidence are the limbs, trunk, head, neck, and posterior peritoneal cavity: less commonly, these lesions arise in female reproductive organs. This report documents a case of benign fibrous histiocytoma arising in the ovary of 48 year-old female whose chief complaint was abdominal pain.

Cavernous hemangiomas rarely involve the female genital tract. It is difficult to identify vascular malformations when these lesions are concealed in the vagina or deep vulva area. We present a rare case of vaginal cavernous hemangioma in a 30-year-old primiparous woman with an early severe postpartum hemorrhage (PPH) and delayed continuous bleeding from the episiotomy site. She was treated successfully with transarterial embolization of the left vaginal artery. To our knowledge, this is the first reported case of PPH caused by rupture of a vaginal hemangioma during vaginal delivery in English literature.

Cerebrovascular complications are of the most frequent intracranial complications of bacterial meningitis. Most of the previous reports suggest that the prognosis for the pafients with cerebrovascular complications was unfavorable. We recently experienced a case of meningococcal meningitis with fulminant meningococcemia associated with multifocal non-enhancing lesions on, initial brain MRI. These lesions were hyperintense on T2weighted image and were located in left basal ganglia, both medial thalami, periventricular white matter, left cerebellar hemisphere, and right midbrain and were considered to be resulted from small vessel involvement. Gram negative diplococci were detected by Gram staining of specimens from skin lesion. After antimicrobial therapy and glucocorticoid replacement the patient was recovered without any neurologic sequelae. After one month, follow-up MRI showed resolution of all the ischemic lesions except in midbrain. Additionally there was a small focal hemtoma formation in left basal ganglia. The small hematoma was considered to be resulted from rupture of microaneurysm and disappeared on follow up MRI performed after 3 months. This case suggests that the cerebrovascular complications in meningococcal mningitis might be treated successfully.

Tufted hair folliculitis is an inflammatory disorder of the scalp characterized by a peculiar tufting of hair within areas of scarring alopecia. Histopathological studies reveal perifollicular inflammation around the upper portions of the follicles sparing the hair root level. Within areas of inflammation, several follicles converge toward a common follicular duct with a widely dilated opening. The cause of tufted hair folliculitis is unknown, and the therapeutic approach is problematic. We present herein a patient with a 28-year history of recurrent and progressive tufted hair folliculitis. A 33-year-old man was referred to our department for the treatment of chronic and relapsing inflammatory lesions of the scalp. The clinical examination revealed a circumscribed area of 15cm length and 10cm width on the occipital area of the scalp which was characterized by hair tufting and exudates. Histopathologic findings were typical for tufted hair folliculitis. We believe that hair tufting is a secondary phenomenon which may occur in several inflammatory diseases of the scalp.

Histopathology of pulmonary lymphangioleiomyomatosis(LAM) is studied using four new cases and six previously reported cases, which include two cases without definite evidence of LAM. The important diagnostic features of this lesion were nodular proliferation of immature smooth muscle and cleft or cyst formation within the nodules of smooth muscle cells. The nuclei of the smooth muscle cells were bigger than those of blood vessels or fibrotic lung, and the direction of nuclei was irregular. The lung parenchyma showed little inflammatory change but there were multiple air cysts with smooth muscle nodules at their margin. There were two cases with exuberant proliferation of smooth muscle nodules and two cases with papilliferous projections of the cells into lymphatic lumen. Whereas, three cases had only a few small slender nodules of smooth muscle cells at the margin of air cyst. The lymphatic lumen with smooth muscle nodules is dilated in four cases but other four cases show collapsed lumen. Pulmonary hemorrhage and hemosiderosis were prominent in three cases. There were variety of histology in terms of the cellularity of smooth muscle nodules, the size of the lymphatic lumen and the degree of pulmonary destruction, which may have significance on the clinical presentation and prognostication.

Cancers of an unknown primary site are heterogenous with respect to their clinical and pathologic features. They are generally very aggressive, but specific favorable subsets have a better prognosis. For these favorable subsets, taxane based chemotherapy is very effective for a subset of woman with papillary serous peritoneal adenocarcinoma. A 52 year-old woman underwent [18F]-FDG PET/CT for routine health screening. On PET/CT, multiple hypermetabolic lymph nodes were detected in the paraaortic spaces, and there were no other hypermetabolic abnormalities. The patient was diagnosed with an unknown primary cancer that probably originated from the ovary or peritoneum, according to clinical studies and biopsy results. This was not a typical case of a favorable subset of cancer of an unknown primary site, but the tumor showed complete biologic response to taxane based chemotherapy as revealed by PET/CT, and necrotic tumor cells were confirmed by surgery.

Objective: : The fate of partially thrombosed intracranial aneurysms (PTIAs) is not well known after endovascular treatment. The authors aimed to analyze the treatment outcomes of PTIAs. Methods: : We retrospectively reviewed the medical records of 27 PTIAs treated with endovascular intervention between January 1999 and March 2018. Twenty-one aneurysms were treated with intraluminal embolization (ILE), and six were treated with parent artery occlusion (PAO) with or without bypass surgery. Radiological results, clinical outcomes and risk factors for major recurrence were assessed. Results: : The initial clinical status was similar in both groups; however, the last status was better in the ILE group than in the PAO group (p=0.049). Neurological deterioration resulted from mass effect in one case and rupture in one after ILE, and mass effect in two and perforator infarction in one after PAO. Twenty cases (94.2%) in the ILE group initially achieved complete occlusion or residual neck status. However, 13 cases (61.9%) showed major recurrence, the major causes of which included coil migration or compaction. Seven cases (33.3%) ultimately achieved residual sac status after repeat treatment. In the PAO group, all initially showed complete occlusion or a residual neck, and just one case ultimately had a residual sac. Two cases showed major recurrence, the cause of which was incomplete PAO. Aneurysm wall calcification was the only significantly protective factor against major recurrence (odds ratio, 36.12; 95% confidence interval, 1.85 to 705.18; p=0.018). Conclusion : Complete PAO of PTIAs is the best option if treatment-related complications can be minimized. Simple fluoroscopy is a useful imaging modality because of the recurrence pattern.
