  • Purpose: Dermatofibrosarcoma protuberans is a rare tumor, accounting for 0.1% of all malignant tumors. Although metastasis is very uncommon, local recurrence occur frequently. Dermatofibrosarcoma protuberans occurring in children is even more rare; this is the first case report of congenital dermatofibrosarcoma protuberans in Korea. Methods: The patient is a 14-month-old male infant with a lesion that was first thought to be a birthmark. The lesion grew larger, and a punch biopsy revealed dermatofibrosarcoma protuberans. A wide local excision was performed with a 2 cm peripheral resection margin beyond the gross tumor lesion. Deep fascia and a portion of muscle underneath the central part of the lesion were also taken. The surgical defect was covered by a split-thickness skin graft. Results: There has been no clinical sign of recurrence over one year after the surgery. Conclusion: A patient with congenital dermatofibrosarcoma protuberans detected at an early stage underwent a wide local excision of the tumor after accurate diagnosis was carried out by biopsy and immunohistochemical studies. There was no clinical evidence of tumor recurrence during over a 1-year follow-up.

  • Objective: To determine STAT3, P-STAT3, and VEGF-C expression levels in small cell lung cancers (SCLCs), and discuss their role and clinical significance in SCLC development. Method: Immunohistochemical methods were applied to 128 cases of SCLC and 40 cases of adjacent normal tissue. Results: The expression levels of STAT3, P-STAT3, and VEGF-C were higher in SCLC than in normal tissue (P<0.05). Pairwise comparisons showed positive correlations with lymph node metastasis, clinical stage, and tumor size (P<0.05). The expression levels were also related with the overall survival rates. Conclusion: STAT3 and VEGF-C play important roles in the development of SCLC, and might be expected to become new targets for SCLC treatment.

  • Background: Biomarkers in breast neoplasms provide invaluable information regarding prognosis and help determining the optimal treatment. We investigated the possible correlation between cancer stem cell (CSC) markers (CD133, and ALDH1) in invasive ductal breast carcinomas with some clinicopathological parameters. Aim: To assess the correlation between expression of cancer stem cell (CSC) markers (CD133, and ALDH1) and clinicopathological parameters of invasive ductal breast carcinomas. Materials and Methods: Immunohistochemical analysis of CD133 and ALDH1 was performed on a series of 120 modified radical mastectomy (MRM) specimens diagnosed as invasive ductal breast carcinoma. Results: Expression of both CD133 and ALDH1 was significantly changed and related to tumor size, tumor stage (TNM), and lymph node metastasis. A negative correlation between CD133 and ALDH1 was found. Conclusions: Detecting the expression of CD133 and ALDH1 in invasive ductal breast carcinomas may be of help in more accurately predicting the aggressive properties and determining the optimal treatment.

  • We have studied Meckel's diverticulum(MD) of the duck(Anas platyrhynchos platyrhyncos, Linne) by histological and immunohistochemical methods. Because MD were first observed in 2 weeks after hatching, tissues were taken from 2 weeks to 32 weeks after hatching groups. MD were observed as like any parts of intestinal tract that composed with simple columnar epithelium and numerous mucosal gland especially, cecum except that many lymphocytes were exist in this study. Also a number of bovine chromogranin(BCG)-, serotonin, and somatostatin(SOM)-immunoreactive cells were observed in epithelium and submucosal gland in this study, so it could be suggest that the MD of the duck serve as some digestive and lymphatic functions.

  • In order to study the effects of bee venom herbal acupuncture on the neurotransmitters of the rat brain cortex, herbal acupuncture with the bee venom group and normal saline group was performed bilaterally on the point corresponding to LI 4 of the rat. The average optical density of the neurotransmitters from the cerebral cortex was analyzed 30 minutes after the herbal acupuncture with immunohistochemical methods. The results were as follows: 1. The density of NADPH-diaphorase in the bee venom group was increased significantly at the motor cortex, visual cortex, auditory cortex, cingulate cortex, retrosplenial cortex, and perirhinal cortex, compared to the normal saline group. 2. The average optical density of vasoactive intestinal peptide in the bee venom group had significant changes at the insular cortex, retrosplenial cortex, and perirhinal cortex, compared to the normal saline group. 3. The average optical density of neuropeptide-Y in the bee venom group increased significantly at the visual cortex and cingulate cortex, compared to the normal saline group.

  • Analysis of intraepidermal nerve fibers using skin biopsy is a recently developed technique, providing diagnostic information on small fiber neuropathies. The specimens are obtained by 3 mm punch biopsy, which is safe and minimally invasive. Immunohistochemical staining by Protein gene product (PGP) 9.5 demonstrate not only intraepidermal nerve fibers but dermal structures, such as sweat gland and erector papillae. Up to now, many studies agree that intraepidermal nerve fiber density is dramatically reduced in various sensory neuropathies. The utility of density measure was confirmed with high sensitivity in the diagnosis of sensory neuropathy, comparable to sural nerve biopsy or quantitative sensory testing. Besides quantitative methods, morphological changes like axonal swelling and fragmentation can be used as predegenerative markers. This article reviews the technique of skin biopsy and clinical and experimental usefulness of skin biopsy in diagnosing and monitoring peripheral neuropathies.
