  • In this paper, we propose a skin lesion detection to develop the system of fluorescence image analysis to identify the fluorescence of topical methyl aminolevulinate(MAL) idduced PpIX in patients with BCC accurately. By fluorescence image analysis we define the border between tumo and tumor-free areas on fluorescence image after topical application of MAL ointment. We excised both the tumor and peri-tumoral areas widely from the 10 patients with BCC, and divided tissue samples into 3 area, such as tumor area, suspected tumor area, tumor-free area, respectively. Our proposed method migt play a role as an adjunctive tool to define the border between tumor and tumor-free areas for Mohs' micrographic surgery.

  • The anomalous connection of umbilical vessels to the heart is rare and has not yet been reported in the international scientific literature. Herein, we report the case of a newborn who was diagnosed with an anomalous connection of the umbilical vessels to the left ventricle. These anomalous vessels were functionally open for 2 weeks, and cellulitis was present in the area of the blood vessels connected to the skin. We performed division of these abnormal vessels and removal of the skin lesion.

  • Chronic burn scars often cause various skin malignancies at rates of up to 2%. These lesions are usually squamous cell carcinomas, but rarely, malignant melanoma is reported. We report a 67-year-old male with a malignant melanoma on a burn scar with regional metastasis. This patient presented an ulcerative lesion only in 2 weeks. After histopathological diagnosis, we performed only palliative surgery on patient's demand, and followed up the subsequent deterioration course. Our case reemphasizes the need for rapid diagnosis and treatment when suspect lesions are present on chronic burn scar. Also, physician should be in mind and inform the patient about malignant melanoma and its aggressive course.

  • Aqualyx (Marllor International Ltd, Rimini, Italy) was originally developed in Italy by Professor Pasquale Motolese and has been commercially available since 2009. It is a deoxycholate, aqueous gelatinous solution mixed with saline and buffering compounds. It is the only drug approved by the European Union for the reduction in localized fat. Aqualyx is sold exclusively to doctors and nurses trained in intralipotherapy. In the case of our patient, the product administered was advertised as Aqualyx, but was not administered by a trained health professional and was administered too superficially. The patient developed severe pain following the injection and was unable to sit for several weeks. There was localized skin necrosis, and palpable collections where the injection was administered. Our initial suspicion was development of an abscess or hematoma. To characterize further, we arranged an ultrasound scan that showed a "superficial hypoechoic lesion" but no deeper infection or spread. The numerous painful nodules ruptured onto the skin surface, resulting in purulent and bleeding lesions. This case demonstrates the importance of appropriate training and competence in performing cosmetic procedures including injections and fat dissolving treatments.

  • Nevus sebaceous of Jadassohn is a congenital cutaneous hamartoma with epidermal, sebaceous, follicular, and apocrine structures that usually appears at birth or in early childhood. It has the potential to generate a variety of secondary neoplasms of different lineages, and the risk increases with patient age. Although multiple neoplasms may occasionally arise within the same lesion, the coexistence of more than five secondary tumors is extremely rare. Here we report a case of seven secondary tumors including syringocystadenoma papilliferum, desmoplastic trichilemmoma, sebaceoma, trichoblastoma, pigmented trichoblastoma, sebaceous adenoma, and tumor of follicular infundibulum arising within a nevus sebaceous. The complete diagnosis relies on the histopathological analysis of multipoint biopsies and delicate pathological sections.

  • Fifteen dogs with superficial pyoderma were investigated clinically. Dermatological signs were mainly consisted of papule (66.6%), pustule (86.6%), epidermal collrarette and patchy (40%), and hyperpigmentation (53.3%). Distribution of skin lesion were consisted of back (35.5%), abdomen (29.0%), axillary (6.4%), leg (3.2%), neck (3.6%) and foot (16.1%), respectively. In pustular cytology PMN cells and cocci were examined. Cephalexin was very effective antibiotics on superficial pyoderma at administration of 30mg/kg bid P.O. for 3 weeks. Hyperadrenocorticism and atopy were diagnosed as a primary cause on pyoderma in 2 dogs.

  • The results of treatment of eighteen lesions of fibrous dysplasia which of them seventeen lesions were treated with surgery were reviewed at the Department of Orthopedic Surgery, College of Medicine, Hanyang University Hospital. We studied to evaluate the functional clinical results and the recurrence according to the type of disease, grafted bone, methods of treatment and location of lesion. We treated sixteen patients(five males and eleven females) and their mean age was 22.6 years. There was no association with skin pigmentation or dysfunction of endocrine system. Twelve patients had a monostotic pattern and four patients had a polyostotic pattern. Twelve lesions were treated with curettage and bone grafting and four lesions in the proximal femur were treated by internal fixation with curettage and bone grafting. One lesion was treated by en-bloc resection. There were eleven satisfactory results in twelve monostotic lesions and there were four satisfactory results in five polyostotic lesions, but the recurrence were four cases, respectively. The two unsatisfactory results were seen in two patients treated by autografting, but there were three recurrence of four lesions in autografting only, one of five in autografting and allografting, four of eight in allgrafting or xenografting. Four of six lesions in upper extremity were recurred after curettage and bone grafting and five of them showed satisfactory results. In pelvic and lower extremity lesions, the recurrence were occurred in two lesions after curettage and bone grafting and in two lesions after internal fixation and bone grafting. The recurrence does not always provide an unsatisfactory functional results and the recurrence showed higher rate in radiologic pattern of ground glass appearance with-out marginal sclerotic rim, but the recurrence according to grafted bone showed similar rates. Curettage and bone grafting is adequate for a symptomatic lesion and firm internal fixation is needed for a lesion in proximal femur. In use of grafted bone, xenograft or allograft may be preferable to autograft because of the disadvantage of autografting like a increased blood loss, prolonged operation times, etc.
