Lichenoid keratosis (LK), a lichen planus-like keratosis, is a rather frequent skin disorder that has some histological features similar to lichen planus. However, the classification system for LK has not been settled. We report two cases of LK and propose a new classification for LK correlating with clinicohistopathological findings.

Winkelmann granuloma is a very rare disorder characterized by histologic findings of perhaps[ic] infiltration, collagen degeneration, and granulomatous inflammation, which usually show palisading features. A number of diseases, especially systemic immunoreactive diseases, are associated with this disorder. We describe a focal neutrophilic necrosis : type of Winkelmann granuloma associated with hypothy- roidism and rheumatoid arthritis.

Indeterminate cell proliferations are rarely described in dermatology literature. Indeterminate cells are characterized by positivity for S-100 protein and CD-la, but are distinguished from Langerhans cells by the absence of Birbeck granules. We present a case of congenital indeterminate cell histiocytoma in a 6-day-old male infant. A Skin examination revealed a solitary, erythematous, 6*6cm, superficially crusted, dome shaped papule on his forehead. A Histopathologic examination showed a dense cellular infiltrate in the dermis, below the atrophic epidermis. Frequently, the nucleus demonstrated a single cleft or crease like the shape of a kidney. These cells showed positivity for S-100 protein. Birbeck granules were not found on electron microscopic examination.

Blastomycosis-like pyoderma is a rare reaction pattern to a superficial bacterial infection in persons with a variety of underlying coniditions, including inflammatory and neoplastic pathologic conditions, and in associaton with a primary immunodeficiency state. We describe a clinically recurrent blastomycosis-like pyoderma on the right ankle area in an otherwise healthy man.

BACKGROUND/OBJECTIVES: Although the antioxidative effects of lycopene are generally known, the molecular mechanisms underlying the anti-inflammatory properties of lycopene are not fully elucidated. This study aimed to examine the role and mechanism of lycopene as an inhibitor of inflammation. METHODS/MATERIALS: Lipopolysaccharide (LPS)-stimulated SW 480 human colorectal cancer cells were treated with 0, 10, 20, and 30 µM lycopene. The MTT assay was performed to determine the effects of lycopene on cell proliferation. Western blotting was performed to observe the expression of inflammation-related proteins, including nuclear factor-kappa B (NF-κB), inhibitor kappa B (IκB), mitogen-activated protein kinase (MAPK), extracellular signal-related kinase (ERK), c-jun NH2-terminal kinase (JNK), and p38 (p38 MAP kinase). Real-time polymerase chain reaction was performed to investigate the mRNA expression of tumor necrosis factor α (TNF-α), interleukin-1 beta (IL-1β), interleukin-6 (IL-6), inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2). Concentrations of nitric oxide (NO) and prostaglandin E2 (PGE2) were determined via enzyme-linked immunosorbent assays. RESULTS: In cells treated with lycopene and LPS, the mRNA expression of TNF-α, IL-1β, IL-6, iNOS, and COX-2 were decreased significantly in a dose-dependent manner (P < 0.05). The concentrations of PGE2 and NO decreased according to the lycopene concentration (P < 0.05). The protein expressions of NF-κB and JNK were decreased significantly according to lycopene concertation (P < 0.05). CONCLUSIONS: Lycopene restrains NF-κB and JNK activation, which causes inflammation, and suppresses the expression of TNF-α, IL-1β, IL-6, COX-2, and iNOS in SW480 human colorectal cancer cells.

BACKGROUND AND OBJECTIVES: Although CO2 laser turbinate surgery is known to be an effective method in reducing the nasal symptoms of perennial allergic rhinitis, the long term effects have not yet been evaluated. Therefore, the purpose of this study was to assess the subjective and objective long term results of CO2 laser surgery. MATERIALS AND METHODS: The charts and questionnaires of 49 patients who received laser surgery at our department from January 1994 to December 1999 were reviewed. Preoperative and postoperative nasal volume of 20 randomly selected patients were measured by acoustic rhinometry. Nasal mucosa of 10 patients before and after laser surgery yearly for 6 years were examined under light and electron microscopy. RESULTS: Watery nasal discharge, nasal obstruction and sneezing had improved significantly after laser surgery. Postoperative nasal volumes also increased significantly. Histological findings 6 years after laser surgery revealed focal squamous epithelium and regenerating ciliated columnar epithelium. Decreased goblet cells, fibrous proliferation and scarce vessels and glands were also observed. CONCLUSIONS: CO2 laser surgery proves to be an effective method in reducing the symptoms of perennial allergic rhinitis for short and long periods.

OBJECTIVE: The aim of this investigation was to analyze the association between ovarian tumor markers and the clinicopathologic features of ovarian mature cystic teratoma. METHODS: The medical records of 195 patients whose pathologic diagnosis were made as mature cystic teratoma after surgery from June, 2000 to July, 2006 at Ewha Womans University Mok-dong Hospital were reviewed. The proportions of elevation of each tumor marker were evaluated in all patients and CA19-9 which showed the greatest elevation rate was selected as a promising relevant tumor marker. The patients were alloted to either Group I showing elevated CA19-9 or Group II showing normal level of CA19-9. The relationship between CA19-9 level and demographic data or clinicopathologic features were investigated by usual statistical method. RESULTS: The mean age of all patients was 35.4+/-12.8, and the average size of tumor was 7.1+/-3.5cm. Bilaterality of the mature cystic teratoma was 12.8%. The proportion of the patients showing elevated levels was greatest in CA19-9 as 33.3% (65/195), compared with 12.0% in CA-125, 5.8% in CEA, 1.1% in AFP. Significant difference between Group I and Group II were found in age, parity, tumor size, and bilaterality. Bilaterality and tumor size were greater in Group I, and age and proportion of parous women were lower in Group I. On the other hand, the rate of ovarian torsion or laparotomy conversion showed no difference. Likelihood ratio for bilaterality which may be clinically used during surgical procedure were 2.2 for CA19-9 suggesting its potential role in gynecologic practice. CONCLUSION: This study shows that CA19-9 may be a useful tumor marker associated with tumor size and bilaterality in ovarian mature cystic teratoma. Further confirmative study with larger sample size is in need in order to establish its definite clinical role in ovarian mature cystic teratoma.

Although ultrasonography is regarded as the gold standard in the diagnosis of obstructive nephropathy, dilatation is sometimes not observed by ultrasonography. We report upon a case of minimally dilated obstructive nephropathy due to an ureter stone in a kidney donor with volume depletion. A 54-year-old man was admitted due to anuria and abdominal pain of 2 days duration. Ten years previously, his right kidney was donated for transplantation, and one month before admission, he abstained from all food except water and salt, for 30 days for religious reasons. He had lost 8 kg of body weight. On admission, he had clinical signs of volume depletion, i.e., a dehydrated tongue and decreased skin turgor. Laboratory data confirmed severe renal failure, his blood urea nitrogen level was 107.3 mg/dL, and his serum creatinine 16.5 mg/dL. The plain X-ray was unremarkable and ultrasonography showed only minimal dilatation of the renal collecting system. On follow-up ultrasonography, performed on the 5th hospital day, the dilatation of the collecting system had slightly progressed and a small stone was found at ureter orifice by cystoscopy. Removal of stone initiated dramatic diuresis with a rapid return of renal function to normal by the third day.
