Primary leiomyosarcomas are extremely rare. Its clinical configuration is a round to oval, more or less hemispherical elevation of the skin, but the appearance of these lesion is not distinctive so that the diagnosis is established by the histopathologic findings. Microscopically the cutaneous leiornyosarcomas consist of a poorly delineated proliferation of spindle shaped atypical myomatous cells arranged in interlacing fascicles which merge into collagenous stroma. We experienced a case of primary cutaneous leiornyosarcoma which developed as a hen egg sized tumor on the left shin in a 71-year-old woman and present this case with the review of 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.

Vulva syringomas are rare in reviewing literature. In our case, a 29-year-old had multiple papular lesions involving both sides of the vulva. Microscopically the lesion showed dilated cystic sweat ducts some of which have small comma like tails resembling tadpoles. It is the purpose of this report to present a rare case of syringoma which was limited to the vulva without involvement of other sites.
