Background and Objectives : Interstitial cells of Cajal(ICC) are the pacemakers in gastrointestinal tract that modulates gastrointestinal motiliey and these cells also transmit neural input from enteric nerves to smooth muscles. Recent work on tissues from patients with motility disorders that suggest that loss or defect in ICC could be related to pathophysiology in human and animal models. Immunolabelling of ICC in intestinal wall is recently developed by using specific marker, anti-c-kit antibody. Immunohistochemistry was done for ICC network in attempt to provide a morphological basis for the mechanism regulating gastrointestinal motility Methods : Cryosection was done, and whole-mount preparations of mouse stomach, gastrointestinal tract were immunolabelled using the anti-c-Kit. Immunolabelled ICC networks were observed under a confocal laser scanning microscopy. Results : According to three dimensional reconstruction study, we found that the c-Kit-positive celluar networks were widely distributed in the gastrointestinal muscle (1) circular muscle layer(IC-IM), (2) myenteric plexus(IC-MY), (3) deep muscular plexus(IC-DMP) in ileum, (4) submucosal plexus(IC-SMP) and longitudinal muscle layer(IC-LM) in colon. Conclusion : The characteristic profiles of ICC celluar networks provide a morphological basis upon the mechanism regulating gastrointestinal motility. Additional studies for the enteric nerves-ICC interaction are need to evaluate the detailed roles of Icc in gastrointestinal tract.

Background: Acquired bilateral telangiectatic macules (ABTM) are a newly recognized clinical entity with multiple telangiectatic pigmented macules confined mostly to the upper arms. Objectives: To evaluate clinical and dermoscopic features in a group of 50 patients with ABTM and to determine the usefulness of dermoscopy for identifying patients with chronic liver diseases (CLD) Methods: Patients were selected from two tertiary teaching hospitals in Korea. Overall, 50 patients with ABTM in the skin were included in the study. The dermoscopic findings were graded on a 0-3 scale of severity: none (0), mild (1), moderate (2), severe (3). Results: We identified three valuable dermoscopic features in diagnosing ABTM including brown pigmentations, telangiectasia and angioid streak pattern. The brown pigmentations from the group without CLD were scored more severely than the group with CLD (mean score: 2.00 vs 1.48, P < 0.001). The mean severity score of telangiectasia from the group with CLD was higher than the mean from the group without CLD (2.14 vs 1.39, P < 0.001). The angioid streak pattern was characterized as bilateral, narrow and irregular lines configuring in a radiating fashion. The angioid streak pattern was observed in 63.0% of patients with and 26.1% of those without CLD (1.37 vs 0.35, P < 0.001). Conclusion: The detailed observations in ABTM with dermoscopy provide the first clues for the underlyingchronic liver disease.
Case Reports : Giant Piloleiomyoma of the Forehead

Cutaneous piloleiomyomas are benign smooth muscle tumors arising from the arrector pili muscles. Piloleiomyomas appear as firm dermal papules of skin color or with a reddish to brown surface, and are commonly located on the extremities. Histologically, these lesions are composed of interlacing bundles of smooth muscle cells in the reticular dermis. Our case presented with an unusually large nodule on the forehead that was accompanied by intermittent pain. Histological analysis was compatible with piloleiomyoma and the lesion showed haphazardly arranged bundles of smooth muscle in the dermis. We describe herein an interesting case of a giant piloleiomyoma occurring on the forehead. (Ann Dermatol 23(S2) S144~S146, 2011)
Case Reports : Delayed Diagnosis of Scrofuloderma Misdiagnosed as a Bacterial Abscess

An 82-year-old woman presented with a four-month history of an ulcerative plaque overlying her left neck. This lesion had developed as a subcutaneous nodule, gradually increased in size, and evolved into ulcers. Before visiting our Dermatology clinic, the patient had been diagnosed as having a bacterial abscess, but treatments with antibiotics were unsuccessful. The presence of a purulent discharge and prominent ulceration caused further confusion as bacterial abscess, and radiologic evaluation on computed tomography also led to the possibilities of secondary lesions from an abscess or malignancy. However, the characteristic appearance of her lesion allowed us to discern cutaneous tuberculosis, especially scrofuloderma. Based on clinical examinations, staining for acid-fast bacilli, and positive findings of polymerase chain reaction, a quick diagnosis of scrofuloderma was made. After that, she was treated successfully with anti-tuberculosis therapy and the ulcer healed. Our case highlights the problem of delayed diagnosis of scrofuloderma presenting as a bacterial abscess. In conclusion, having a high index of suspicion is needed to diagnose cutaneous tuberculosis correctly. (Ann Dermatol 24(1) 70∼ 73, 2012)

Background: Labial melanotic macules are benign pigmented lesions that may clinically mimic melanoma. Whereas the dermoscopic features of other pigmented skin lesions have been extensively described, little is known about labial melanotic macules. Objectives: To describe the dermoscopic aspects of labial melanotic macules and find schematic dermoscopic patterns to these lesions. Methods: A retrospective dermoscopic study was conducted on 80 lesions with histopathologically proved labial melanotic macules. Results: We describe and define, for the first time to our knowledge, landscape painting patterns found in 65 of 80 melanotic lesions (81.3%), characterized by parallel lines orcircle lines, overlapping vessels with background brown pigmentation. The background brown pigmentations were observed in 74 of 80 lesions (92.5%), the parallel lines in 62 (77.5%), the circle lines in 20 (25.0%), and overlappin vessels in 69 (86.3%). The structureless black pigmentations were only presented in 26 of 80 melanotic lesions (32.5%). Conclusion: Dermoscopy can be useful for the clinical detection of labial melanotic macules, and “Landscape painting patterns” may represent a dermoscopic clue for the diagnosis of these lesions.
