Hemangiopericytoma is a rather uncommon neoplasm composed mainly of cells derived from the vascular pericytes of Zimmermann, which are normally found in close apposition to the endothelial cells of capillaries and postcapillary venules. Authors studied a case in which primary hemangiopericytoma located in the left orbit of a 54-year-old woman. Review of the literatures about incidence, clinical symptoms, histological features and biological behavior of the orbital hemangiopericytoma was presented.

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.

PURPOSE: We studied to know the influence of respiratory virus and atopic characteristics on recurrence of virus-induced wheezing in children under 3 years of age. METHODS: Between March 2006 and February 2009, 340 children who were hospitalized with symptoms of sudden onset of dyspnea, cough and wheezing after symptoms of acute upper respiratory tract infection and detected specific respiratory viruses by multiplex RT-PCR were enrolled. The data were analyzed according to age (< or =6, 7-12, 13-24, and 25-36 months) as well as previous wheezing episodes (first or recurrent episode). Respiratory viruses and atopic characteristics were compared among individual groups. RESULTS: The 3 commonly identified viruses were RSV (62.4%), PIV (15.6%) and RV (11.8%). PIV and RV were significantly associated with recurrence, but RSV was not significantly associated with recurrence. Food sensitization, aeroallergen sensitization, elevation of total IgE, history of atopic dermatitis and history of parent asthma were significantly associated with the recurrent episode, but serum eosinophil and passive smoking were not significantly associated with the recurrent episode. CONCLUSION: These findings show that specific respiratory viruses can have different influence on recurrence and that atopy may be a risk factor for recurrence of wheezing, in children under 3 years of age with virus-induced wheezing.

We report a case of liposarcoma with osteosarcomatous dedifferentiation of the chest wall in a 58-year-old man, which had been initially mistaken as myositis ossificans. CT and MRI demonstrated a soft tissue mass consisting of two components: a non-lipomatous area with amorphous calcification/ossification and a well-encapsulated fatty component. Based on local excision in the non-lipomatous area, myositis ossificans was initially diagnosed. As the mass was gradually enlarging, however, wide excision including the fatty component was performed and histological assessment revealed lipoma-like, well-differentiated liposarcoma with high-grade osteosarcomatous dedifferentiation. Here, we describe the radiological-pathological features of this rare neoplasm.

PURPOSE: To report polymicrobial keratitis involving Pseudomonas aeruginosa, Acinetobacter baumannii, and Ochrobactrum anthropi. CASE SUMMARY: A 53-year-old female complained of pain and secretion in her right eye, which started 6 weeks before her visit. She applied steroid ointment, which was received from the dermatologist, to her eyelid 7 days prior to her visit but this treatment worsened her symptoms. At the initial visit, the visual acuity of the right eye was light perception, and purulent secretions were observed. Using a slit lamp, severe conjunctival hyperemia, hypopyon, and a ring-shaped central corneal ulcer were observed. The anterior chamber and fundus were not observed due to corneal lesions but ultrasonography showed no intraocular inflammation. Infectious keratitis was suspected and cultured by corneal scraping. During the incubation period, 0.5% moxifloxacin, 2% voriconazole, and 1% cyclopentolate were administered. A total of 400 mg of moxifloxacin and 100 mg of doxycycline were given orally. In the primary culture, Pseudomonas aeruginosa and Acinetobacter baumannii were identified so 5% ceftazidime, which was sensitive for the antibiotic susceptibility results was further instilled. Thereafter, the keratitis improved but the keratitis again worsened while maintaining the topical treatment. A secondary culture was positive for Ochrobactrum anthropi. Treatment with 1.4% gentamicin, which was sensitive for the antibiotic susceptibility test was added and the keratitis improved. A conjunctival flap was performed because of the increased risk of perforation. CONCLUSIONS: We report polymicrobial keratitis involving Pseudomonas aeruginosa, Acinetobacter baumannii, and Ochrobactrum anthropi for the first time in the Republic of Korea.
