Intracranial fibro-osseous lesion, also reported as calcifying pseudoneoplasm of the neural axis, is an uncommon lesion of the central nervous system. Since the discovery of this entity by Rhodes and Davis in 1978, there have been a total of 21 cases reported in the literature. We encountered one such case in a 28 year old male, who presented with left hemiparesis for 1 year. By the MR images, a 1.5 cm sized round mass was found at right parietal lobe near motor cortex. The mass lesion enhanced well, homogenously and revealed clear, slightly irregular margin. Excisional biopsy of the mass was performed. Microscopically the lesion was composed of calcified fibrous tissue with an amorphous gray-blue, coarsely fibrillar to chondromyxoid nodular areas. Sparse spindle cells, immunohistochemically negative for GFAP, vimentin and S-100, were scattered within the amorphous material. Palisading spindle or polygonal cells were present at the more cellular periphery of the lesion, which were vimentin positive but S-100 negative. There was no evidence of the pilocytic astrocytes, Rosenthal fibers, or GFAP positive hypertrophic astrocytes. Intracranial fibro-osseous lesions are apparently slow-growing with generally excellent prognosis after wide excision. The etiology remains unclear, but most investigators favor a reactive rather than neoplastic process.

Trichilemmal horn(trichilemmal keratosis) is a rare keratinizing tumor that resembles a cutaneous horn. Histologically, it is characterized by an abrupt maturation of keratinocytes into lamellar keratin without the formation of a granular layer. We describe a case of a trichilemmal horn on the right cheek of a 78-year-old woman.

While lipomas are common in the rest of the body, intracranial lipomas are rare condition which are usually found in the midline of the brain. The majority of these lesions show few or even no symptoms and hardly ever produce alarming neurological defects. We experienced a case of corpus callosum lipoma in a 7 year old boy, who has had headache and loss of consciousness twice. He was diagnosed by skull x-rays and brain CT. We made a brief review of literatures. @PG 428.

A 38-year-old man presented with a black pigmented patch overlying his upper lip, a part of the gingiva and the hard palate. An intradermal tumor mass was palpated at the central portion of the pigmented patch of the upper lip. Diphenylcyclopropenone (DPCP) is a potent contact sensitizer that could stimulate non-specific immunity. We report a case of desmoplastic malignant melanoma (DMM) in which an atypical lentiginous pigmentation disappeared with topical DPCP immunotherapy and the dermal tumor mass was removed by a surgical wedge-shaped excision. Though an atypical lentiginous pigmentation of DMM sometimes undergoes extensive spontaneous regression, in our case it could be attributed to the therapeutic effect of topical DPCP immunotherapy rather than a spontaneous regression.

Preeclampsia is a syndrome of hypertension, proteinuria and generalized edema after the 20th week of gestation and usually abates within 48 hours of delivery. Patients with severe preeclampsia and eclampsia have changes consistent with low grade DIC. In severely ill patients with DIC, generalized but nonspecific signs of fever, hypotension, hypoxia and acidosis may be found. Any pattern of bleeding may be seen, but bleeding from wound or venipuncture site is common. A case is presented of acute respiratory distress resulting from DIC combined with right upper lobe atelectasis and hemothorax after right internal jugular vein cannulation. We report this case along with review of the literature.
