Pityriasis rotunda is characterized by perfectly circular to oval brownish scaly patch on the trunk and extremities. This disease is considered to be a form of acquired ichtkyosis of unknown etiology and develops usually in association with certain systemic diseases, such as tuberculosis, malignant neoplasrn, leprosy, ovarian cyst and uterine myoma etc, We experienced 2 cases of pityriasis rotunda on the abdomen, chest and back associated with liver cirrhosis in 66 year old man 43 year old woman and clinical presentation was made with review of related literatures.

PURPOSE: To analyze the imaging features of brain abscess. MATERIALS AND METHODS: MR studies of nine patients with surgically verified brain abscess were retrospectively reviewed. RESULTS: The shape of abscesses were round(n=6), multilobulated(n=2) or triangular(n=1). All lesions were located in corticomedullary junction and extended into white matter. On gadolinium-DTPA enhanced images, smooth rim-like(n=6) or irregular thick enhancement(n=3) of abscess wall was noted. Budlike projection from the abscess capsule was found in 4 cases. The signal intensity of abscess capsule was either hyperintense (n=5) or isointense(n=4) relative to white matter on Tl-weighted images, and hypointense(n=6), isointense (n=2) or mixed hypo and isointense(n=l) on T2-weighted images. Satellite nodules were found in 2 cases. PNS inflammation(n=2), meningitis(n=1), ventriculitis(=2) and subdural empyema(n=1) were associated CONCLUSION: The MR features of brain abscess included characteristic intensity of abscess capsule, budlike projection from the abscess wall, moderate amount of peripheral edema, satellite nodules, and associated meningitis, ventriculitis or PNS infection. The morphology of abscess wall was not specific for the diagnosis of brain abscess.

A 22-year-old-male patient has numerous brownish-black, soft follicular papules which compatible with acne are scattered on the chest, scapular regions, back and buttocks for 4 5 years duration. Biopsy specimen revealed cystic structures in the mid-dermis lined by squamous cell epithelium w4ich contained laminated keratinous material and varying number of vellus hairs, histopathologically, compatible with diagnosis of eruptive vellus hair cysts. Related literatures and histogenesis were discussed,

Monilethrix is a rare familiar disorder of unknown cause, occurring in either sex, and ueually confined to the scalp. In most cases it is manifested in early childhood. lt is characterized by localized or widespread dystrophy of hair and follicles, the shafts showing regular variations in diameter producing alternate "nodes" and "internodes" which confer a striking beaded or moniliform appearance on the hair. We experienced a case of monilethrix, which was associated with keratosis pilaris and occurred in three generations. The patient's one sibling, mother, 4 uncles and 2 aunts of mother side and grandmother with her sister were all affected with a similar diaorder of hair.

Respiratory syncytial virus (RSV) and Influenza virus are the most common pathogen for causing severe upper respiratory infection in all age groups. A multiplex reverse transcription polymerase chain reaction (RT-PCR) has been developed to detect and subtype influenza A (H3N2 and H1N1), B virus and RSV simultaneously in one tube reaction. Amplification with primers derived from conserved sequences within the nucleocapsid for RSV and hemagglutinin subunit for Influenza A (H3N2 and H1N1) and B viruses yielded a 384 bp, a 300 bp, a 236 bp and a 151 bp, respectively. Assay specificity was confirmed by pulse field gel electrophoresis and autosequencing method. Assay sensitivity was 3 PFU/ml of RSV, 22 PFU/ml, 45 PFU/ml of Influenza type A (H3N2 and H1N1) and 6.6 PFU/ml of Influenza B virus by plaque assay. A rapid and sensitive detection method of a one-tube with multiplex RT-PCR capable of identifying more than one viral template as well as synchronizing reverse transcription and PCR had the potential to produce considerable savings of time and cost effectiveness in the diagnostic laboratory.

PURPOSE: To analyze the characteristies of traumatic brainstem injury by CT and MR MATERIALS AND METHODS: CT and MR studies of 10 patients with traumatic brainstem lesion in MR were retrospectively reviewed, particularly attended to location, signal intensity and associated lesions. RESULTS: CT failed to depict 8 of 10 brainstem lesions. All lesions were detected in MR images with T2-weighted images showing higher detection rate (n=10) (100%) than Tl-weighted images (n=3) (30%) or CT (n=2) (20%). The brainstem lesions located in the dorsolateral aspects of the rostral brainstem(mid brain and upper pons)in 7 (70%) cases, in ventral aspects of rostral brain in 2 (20%) cases and in median portion of pons in 1 (10%) case. Corpus callosal (n=5), Iobar white matter(n=5) diffuse axonal injury, and 2 hemorrhagic lesions in basal ganglia were the associated findings. CONCLUSION: MR imaging is more helpful than CT in the detection of brainstem injury, especially T2 weighted images. Primary brainstem lesions were typically located in the dorsolateral aspect of rostral brainstem(midbrain and upper pons). Corpus callosum and white matter lesions were frequently associated.

Purpose: We report a lenticular cyst in an 8-year-old boy.Case summary: An 8-year-old boy visited our clinic with reduced visual acuity. On slit lamp examination, an immobile lenticular cyst was evident on the posterior lens capsule of the left eye. There was no other abnormality. He had no history of ocular trauma or surgery. His Snellen best-corrected visual acuities (BCVAs) were 1.0 (-0.50 Dsph 0.50 Dcyl ×180°) in the right eye and 0.3 (+3.25 Dsph 1.00 Dcyl ×180°) in the left. After diagnosis of a primary lenticular cyst and anisometropic amblyopia, the child was prescribed glasses and occlusion therapy (8 hours daily). After 3 months, the BCVA improved to 0.9 in the left eye and was maintained. No change in lenticular cyst size was observed during 8 months of follow-up. Conclusions Primary lenticular cysts are very rare in children. When the cyst is too small to occlude the visual axis, amblyopia treatment (glasses and occlusion therapy) is preferable to surgery, being both non-invasive and effective.

We report a case of tinea corporis occurring in one family caused by Trichophyton verrucosum. Father, mother and a son in a family had well defined scaly erythematous patches on the forearm, cheek and postauricular area. Histopathologically fungal hyphae were found in the horny layer of the epidermis in PAS stained sections. In mycological study, charact,eristic feature of T. verrucosum were found. The possible source of the infections was the cattle that they raised in their house. After eight weeks administration of ketoconazole, the lesions were healed leaving slight brownish discoloration.
