We report a case of multiple cutaneous focal mucinosis in a 22 year-old male, who presented with multiple, asymptomatic, nodular lesions on the left upper trunk and left arm which had persisted for about one year. They were 2 to 17 mm in size, firm, yellowish, dome-shaped elevated, slightly movable papules or nodules which were distributed over the area of the left C3-7 and TI-3 sensory dermatomes. The histopathologic findings showed homogeneous mucinous material in the upper dermis. The material was confirmed to be hyaluronic add by, alcian blue stain. Some of the lesions showed improvement with intmlesional injection of triamcinolone acetonide. Such an entity, to the best of our knowledge, has not yet been reported.

A 17-year-old male had a coin sized, follicular plaque on the glabella for 3 months. Histopathologic examination revealed reticular degeneration in the pilosebaceous follicles and amorphous homogenous materials between the degenerated cells. Alcian blue and toluidine blue stained the material as blue and metachromatically purple, respectively. The material was subsequently confirmed as acid mucopolysaccharide. Two months after the initial visit, the lesion showed a tendancy to heal spontaneously. According to the data obtained, the case was considered as an acute benign form of follicular mucinosis.

We report a case of an uncommon cutaneous neoplasm of nerve sheath myxoma in a 25-year-old woman who had a papule on the left cheek of her face. The histologic findings of the lesion showed that lobulated tumors were composed of spindle shaped and stellate tumor cells in an abundant matrix of mucosubstances. The electron microscopic findings showed numerous cytoplasmic myelin figures, and interdigitating long cytoplasmic processes. 5-100 protein was not discovered and alcian blue and PAS stain showed positive. After surgical excision of tumor, the patient did not have any evidence of disease for one year.

BACKGROUND/AIMS: Intestinal metaplasia (IM) has been regarded as a premalignant condition. This study evaluated the role of the transforming factor CDX2 according to the severity and type of IM. METHODS: This analysis was performed on 383 subjects with IM in the antrum and/or body, with diagnoses that were categorized as controls, dysplasias, and gastric cancers. The IM grades were classified into four groups as negative, mild, moderate or severe using the updated Sydney scoring system. The IM subtypes were categorized as type I, type II, and type III using high iron diamine and alcian blue (pH 2.5) staining. The CDX2 expression in the IM foci was evaluated using immunohistochemistry in specimens from the antrum and/or body. RESULTS: CDX2 expression increased according to IM severity (p=0.001) but was not associated with the IM subtype (p=0.881) in the antrum specimens. Similarly, CDX2 expression increased according to the IM grade (p=0.001) but was not associated with the IM subtype (p=0.755) in the body specimens. CDX2 expression was also increased according to baseline disease in the antrum, especially dysplastic and GC group (p=0.003), but not in the body (p=0.582). However, status of Helicobacter pylori infection was not associated with CDX2 expression in the antrum (p=0.692) and body (p=0.271). CONCLUSIONS: These results show that CDX2 expression is associated with the IM grade regardless of the IM subtype and that it was more frequent in the dysplasia group. These results suggest that CDX2 expression might play an important role in the progression of IM in various environments that can affect neoplastic change.

BACKGROUND: The various manifestations of intrinsic cutaneous aging may reflect the age-related changes of dermal ground aubstances, the important components of the dermis. OBJECTIVE: This study was undertaken to observe whether there is any age-relsted change, quantitatively and qualitatively, in dermal glycosaminoglycan(GAG) METHODS: The Senescence-A.ccelerated-Mice(SAM) strain "Prone" to develop senescence(P/8), aged 4 days(P-Y a group, n=5) and 4 months old (P-0 group, n=5) were used, with SAM strain Resistance to senescence (R/1), aged 4 montha old (R-0 group, n=5). The whole skin of SAM was incubated in 0.1 sodium phosphate buffer(NaPB), 2M guanidine-HC1, and 4M guanidine-HCl, sequencially, for the extractiop of GAG. The amount of GAG was measured by using alcian blue and by methylene blue metachrometic assay. Uronic acid(UA) was estimate l employing carbazole reaction. Extracted skin protein profiles were analyed by SDS-PAGE. RESULTS: 1. The total contents of GAG per wet weight of skin, as measured uairq, alcian blue, was highter in R-0 group than R-Y and P-Y group, which is statistically significant. 2. The methylene blue metaehromatic assay yielded highter absorbance values in 2M guanidine-HCl extract than NaPB ext:racts. 3. The total contents of UA decreased with aging in R strains, buttriking increase was noted in the P strain. 4. On SDS-PAGE, the protein profiles of NaPB extracts showed similarity to serum protein. 125 kDa protein band was noted only in guanidine-HCl extracts. 37.40kDa protein bands were appeared in 2M, 4M guanicline-HCl extract of R-0 group. But. there was no significant difference in both strains. CONCLUSION: These findings suggest that macromolecules, such as GAG, is one of the target molecules of the cutaneous eging process, and these change muy be related to the age-related changes of dermal water content.

Florid cemento-osseous dyspalasia (FCOD) is a benign, non-neoplastic lesion characterized by multiple sclerosing masses only within jawbones. It is frequently confused with chronic diffuse sclerosing osteomyelitis (CDSO) in previous literatures. In our study, two cases of FCOD were examined to know the characteristics of their calcifying tissues. The first case was non-infected, while the second case was severely infected, displaying the typical features of CDSO in clinico-radiologic findings. The infected FCOD case showed a lot of bacterial colonies in the main lesion with relatively rare inflammatory reaction. The globular cementum-like materials of FCOD showed woven bone pattern and was positive for Alcian blue stain, and also positive for the antibodies of ameloblastin, bone morphogenetic protein (BMP) -2 and -4. On the other hands, in the immunostains of matrix metalloproteinase (MMP) -3, -9, -10, and TNF- alpha, macrophage infiltrated in the FCOD lesion was rarely observed. These data suggest that the cementum-like materials of FCOD contain various matrix proteins, and that the cementum-like materials are relevant to the overgrowth of the bacterial colonies by inhibition of the regional inflammatory reactions.

BACKGROUND: Clear cells are defined as cells that contain abundant, clear, lightly eosinophilic cytoplasm. On rare occasions, clear cell changes have been observed in actinic keratosis (AK). OBJECTIVE: We aimed to evaluate the cytoplasmic contents of clear cells and the clinicohistopathological features of clear cell AK. METHODS: From 456 cases of histopathologically confirmed AK, we selected 30 cases (6.6%) with greater than 10% of clear cells in the epidermis. We collected the demographic data and clinical features for all specimens. In addition, the specimens were divided into five histopathologic types: hypertrophic, atrophic, Bowenoid, acantholytic, and pigmented. Clear cell distribution was classified into 3 categories: upper, middle, and lower areas of the epidermis. Periodic acid-Schiff (PAS), PAS diastase (d-PAS), and alcian blue staining were carried out, and immunoperoxidase stainings were performed for S-100, HMB45, and cardio embryonic antigen (CEA) to evaluate the origin of the clear cytoplasm. RESULTS: The cheek was the most common site of involvement. The most frequent lesion color was erythematous (66.7%). Scale and telangiectasia were found in the majority of patients (90% and 66.7%, respectively). The most common histopathological type was Bowenoid, found in 21 cases. This was followed by hypertrophic in 7 cases and pigmented in 2 cases. Seventeen specimens (56.7%) stained positive for PAS and negative for d-PAS. All of the PAS-positive specimens were Bowenoid AK. All specimens stained negative for alcian blue and immunoperoxidase staining results were negative for S-100, HMB 45 and CEA. CONCLUSION: We conclude that clear cells in AK most likely originate due to an accumulation of glycogen or due to hydropic degeneration. The presence of glycogen in clear cells may induce adnexal differentiation to an atypical keratinocyte in AK.

A 45-year-old woman had a bean-sized, asymptomatic, soft nodule on the right buttock for 4 years. Histopafhologic evaluation revealed acanthosis and a central core of adipose tissue with thin papillary and reticular dermis containing eccrine glands. Staining with alcian blue showed a slight increase of mucopolysaccharides in the reticular dermis. We made the diagnosis of pedunculated lipofibroma as a solitary form of nevus lipomatosus superficialis.
