Tubular apocrine adenoma is a well-circumscribed intradermal benign tumor with tubular structures showing apocrine differentiation. Most of those cases occur on the scalp in middle aged women. Histologically, tubular structure with apparent apocrine decapitation secretion, cystic dilatation of tubule, and connection with epidermis are the characteristic features of tubular apocrine adenoma. We presented a case of tubular apocrine adenoma that had recurred after incomplete excision. It showed apocrine decapitation secretion histologically and both eccrine and apocrine differentiation on immunohistochemical study.

Mixed tumor of the skin (chondroid syringoma) is a rare benign tumor composed of epithelial elements intermingled with myxoid or cartilagenous stroma which is not separated by basement membrane. It had been believed to originate from the eccrine gland but recently, it was described to be of apocrine gland origin in case of showing apparent apocrine secretion. We report on a 63-year-old man with a tumor on the right upper eyelid showing typical microscopic features of mixed tumor of the skin. Many apocrine decapitation secretions were seen in tubular structures and follicular differentiations were also seen, which represents the common origin of folliculo-sebaceous-apocrine unit.

Ota nevus is a dermal melanocytic harmatoma derived from neural crest melanoblast and involves skin innervated by the trigeminal nerve. Although most cases are clinically apparent at birth or around puberty, acquired lesions in adults have been rarely reported. We reported a 73 year-old Korean man with Ota nevus of the face and scalp that onset in his eighth decade and accompanied multiple solar comedo of the face.

This study was undertaken to document the effect of transforming growth factor-beta2 (TGF-beta2(TGF-beta2) and basic fibroblast growth factor (bFGF) on the proliferation of pig retinal pigment epithelial cells (RPE). Whereas bFGF increased the proliferation, TGF-beta2 showed the inhibitory effect on the proliferation The inhibitory effect of TGF-beta2 disappeared in RPE subcultured with 10ng/ml of bFGF. Both TGF-beta2- and bFGF-specific antisense oligonucleotides blocked the autocrine effect of the growth factors. PLC-71 -specific antisense oligonucleotide inhibited the effect of TGF-beta2 and bFGF. Genistein inhibited the effect of TGF-beta2 and bFGF in dose-dependent man, ner. The data suggest the involvement. of in PLC-/1 and tyrosine kinase in signalling.

Spondylolisthesis, frequently encountered problems with increasing incidence, has been recognizid as an important clinical entity in orthopaedic field. Several methods were applicated as operative treatment of spondylolisthesis; posterior fusion or H-graft, posterolateral fusion, anterior fusion, fixation with internal devices and etc. During the past 12 years from March 1972 to February 1984, 34 patients among the 42 patients were treated surgically at Department of Orthopaedic Surgery of Ewha Womans University Hospital and following results were obtained. 1. The average age was 45.2 years(19 ~ 64 years) and female was predominent(64.7%). Isthmic type was 17 patients(50.0%), degenerative type was 13 patients(38.2%) and dysplastic type was 4 patients(11.8%). Below 40 year old, dysplastic and isthmic type were predominent and degenerative type was more common in the age group above forties. 2. The most prevalent site was L5-Sl; 21 cases(61.8%) and L4-5; 13 cases(38.2%) in orders. In isthmic type L5-Sl was 13 cases and in degenerative type, L4-L5 was 9 cases. By Meyerding classification, grade I was most common(26 patients, 76.5%). 3. The clinical pictures were low back pain only and little improvement with conservative treatment(type I: 9 patients), low back pain with sciatica(type II: 13), type II plus neurologic signs such as motor weakness, sensory change or change of D.T.R(type III, 10) and little low back pain with mainly sciatica(type IV, 2). 4. Of 34 patients, anterior interbody fusion were done in 10 patients ; posterior and posterolateral fusion with decompression were done in 22 patients. Only laminectomy were done in 2 patients(type IV). 5. Fusion rate was observed in 21 patients(95.5%) among 22 patients with posterior or posterolateral fusion and 8(80%) among the 10 patients with anterior fusion. Postopertive functional results by Gill's criteria were excellent or good in 31 patients(91%). 6. There were no difference in fusion rate and functional results in operative methods.

BACKGROUND: A number of reports have been published regarding the use of imiquimod for the treatment of melanoma in situ and metastatic melanoma. Essential steps in the process of melanoma invasion and metastasis include degradation of basement membranes and remodeling of the extracellular matrix by proteolytic enzymes, including matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs). OBJECTIVE: To evaluate the antiinvasive effect of imiquimod in human malignant melanoma cell lines, SK-MEL-2 and SK-MEL-24, in vitro, and to investigate imiquimod-induced changes in the expression of MMPs and TIMPs. METHODS: Invasiveness of melanoma cell lines following imiquimod treatment was evaluated by invasion assays. In order to investigate the mechanism of the anti-invasive effect of imiquimod, mRNA and protein levels of MMP-2, -9, membrane type 1 (MT1)-MMP, TIMP-1, and -2 were assessed by real-time reverse transcription-polymerase chain reaction, gelatin zymography, and western blotting. RESULTS: Imiquimod treatment decreased in vitro viability of melanoma cells in a concentration-dependent manner. Imiquimod also elicited a concentration-dependent suppression of invasion in both melanoma cell lines. A concentration-dependent decrease in MMP-2 and MT1-MMP protein levels and a concentration-dependent increase in TIMP-1 and -2 protein levels by imiquimod was observed in both melanoma cell lines. However, expression of MMP-9 protein was increased in SK-MEL-2 but decreased in SK-MEL-24 with increasing imiquimod concentrations. Imiquimod elicited alterations in MMPs and TIMPs mRNA levels that parallel the observed changes in protein levels. CONCLUSION: Imiquimod may elicit an anti-invasive effect on human melanoma cells by regulating MMPs and TIMPs.
