Nevus lipomatosus cutaneous superficialis is a very rare skin disease which is characterized by the ectopic presence of rnature adipose tissue in the dermis. There are two clinical variants. The first type is the multiple lesions of zonal distribution usually on the buttocks or the lower back area. Sometimes coalescence of the papules tend to form cerebriform plaques. The second type is the solitary papule or nodule with less restricted tendency in its distribution. We describe a 24-year-old female patient who had a soft yellowish, well defined, fetal head-sized cerebriform tumor with comedo-like plugs on the right buttock and the perineal area. The skin lesions began about 10 years ago and gradually increased in size. Routine laboratory findings were within the normal limit. Histopathological findings are hyperkeratosis, acanthosis, deep crypt-like indenation in the epidermis, and ectopic collection of mature adipose tissue in the derrnis. Diagnosis was confirrned by clinical and histopathological findings. Literature was briefly reviewed for discussion.

Eosinophilic leukemia is a rare variant of granulocytic leukemia. It has distinct clinical features to involve central nervous system, heart, lung and skin more frequently than other leukemia and laboratory findings to reveal persistent eosinophilia with immature tendency, leukocytosis, anernia, thrombocytopenia and usually negative philadelphia chromosome in cytogenetic study. We describe a 33 year-old male patient who has suffered from generalizid weakness exertional dyspnea and has had well defined, hen eggs ized, oval shaped and non-in-durated ulcerative lesions on the right thigh since about 4 months prior to admission. The laboratory findings were persistent leukocytosis, eosinophilia and immature tendency in peripheral blood, nearly 100% cellularity and eosinophilic tendency (70%) in bone marrow aspiration and biopsy, and negative philadelphia chromosome in cytogenetic study. A biopsy specimen from ulcer margin showed relatively intact epidermis and heavy cellular infiltration composed of eosinophilic cytoplasm, dark and indented nucleus in entire dermis. Normal appearing skin also revealed same cellular infiltration in dermis with perivascular and periadnexal pattern.

The clinical observations regarding cutaneous manifestations of in-and outpatients with diabetes mellitus was performed in the Diabetic Clinic, Seoul National University Hospital during the period of 11 months from April, 1979 to March, 1980. The number of patients were total 525, 268 in male and 257 in female. The average age of patients was 51. 1 year-old. Results were as follows, 1. In the 525 patients, 270 patients (51. 1%) revealed various cutaneous manifestations. 2. There were statistical significant differences in sex distributions of infection, pruritus, shin spots, rubeosis and bullosis diabeticorum. 3. Systemic complications sush as retinopathy, neuropathy, nephropathy and hypertension were more frequently observed in the patients with skin microangiopathy than with infection or pruritus. 4. There were not any correlations between fasting blood sugar and cutaneous manifestations

To evaluate the cerebral blood flow in feline hydrocephalic brain, this study was designed to measure the regional cerebral blood flow(rCBF;frontal and periventricular area) by the hydrogen clearance method in different stages of the kaolin-induced hydrocephalus and the postshunt status. The results were as follows: 1) A reduction of rCBF was detected in the left periventricular area at two weeks after kaolin injection. A significant reduction of rCBF was revealed in the left periventricular area at two and four weeks after kaolin injection. However, the rCBF of the left frontal cortex was significantly decreased at four weks after kaolin injection. 2) At one week after shunt operation, the significant restroration of rCBF was found in the left frontal cortex and the left periventricular area.

BACKGROUND: To characterize the ictal electrocorticographic features in relation to surgical outcome in nonlesional neocortical epilepsy (NE). METHODS: Seventeen patients with intractable NE underwent surgeries after chronic subdural recordings. All patients did not have any lesions on brain MRI, which was confirmed by pathology postoperatively. One hundred and eighty one ictal EEGs recorded from subdural electrodes were analyzed. Surgical outcome was determined by seizure reduction rate, and free or more than 75% reduction was defined as favorable outcome. The mean duration of follow-up was 55+/-8.7 months. RESULTS: Reproducible ictal onset zone (IOZ) in more than a half of seizures (p=0.002), and persistent ictal discharges in IOZ from the onset to the end of seizure were found more frequently in the patients with good outcome (p=0.004). Ictal onset patterns consisting of low voltage fast or high amplitude beta spikes predicted a good surgical outcome while rhythmic sinusoidal activity or rhythmic spike/sharp wave were predictive of poor outcome (p=0.01). The ictal onset rhythm consisted of gamma or beta frequencies was more prevalent in the favorable group (p=0.003). CONCLUSIONS: The presence of stable ictal circuit suggested by the consistent earliest activation in more than 50% of seizures and the active participation of IOZ throughout the attack were valuable prognostic factors in addition to the morphology and frequency of ictal onset rhythm.

A non-isotopic in situ hybridization method with biotin-labelled oligonucleotide probes was used to examine growth hormone(GH) and prolactin(PRL) gene expression in 32 patients with pituitary adenomas; 13 were prolactinomas, 8 GH secreting adenomas, and 11 mixed GH and PRL secreting adenomas.Positive immunostaining for GH was found in all patients with GH secreting adenomas, and mixed GH and PRL secreting adenomas. Positive immunostaining for PRL was found in all patients with prolactinomas and 9(81.8%) of 11 mixed GH and PRL secreting adenomas, 5(62.5%) of 8 GH secreting adenomas. Immunohistochemistry revealed that 13 were lactotrope adenomas, 5 somatotrope adenomas, and 14 GH and PRL cell adenomas.In situ hybridization revealed that GH mRNA expression was found in all the patients with somatotrope adenomas and GH and PRL cell adenomas, and 6(46.1%) of 13 lactotrope adenomas. PRL mRNA expression was 100% in lactotrope and GH and PRL cell adenomas, and 4(80.0%) of 5 somatotrope adenomas.The patients with a clinical diagnosis of acromegaly had detectable PRL mRNA in their neoplasm and it is suggested that the PRL cells in the adenomas did not result from dedifferentiation, but from the neoplastic stimulus for some mixed tumors probably occurred in cells previously committed to produce PRL and GH. In lactotrope adenomas, the PRL cells of the patients without expression of GH mRNA may be arised from cells programmed to secrete PRL or precussor PRL cells rather than from mixed GH-PRL cells. The finding that some patients produced mRNA detectable by in situ hybridization, but no hormone detectable by immunohistochemistry within tumor was suggested of a silent adenoma.These observations indicated that in situ hybridization studies may improve the classification of pituitary adenomas and may provide a precise knowledge of the biology of these neoplasms.
