Alveolar soft part sarcoma is a clinically and morphologically distinct soft tissue tumor that was first defined and named by Christopherson et al in 1952. Since 1953, alveolar soft part sarcoma invading bone have been reported sporadically. We experienced a case of alveolar soft part sarcoma with metastasis to femoral shaft, which was treated by wide resection & vascularized fibular strut graft.

Classic Kaposi's sarcoma is a human herpesvirus-8 associated with a multicentric lymphoangioproliferative tumor primarily arising in the lower extremities, but rarely in the head and neck. We herein report a 63-year-old man with primary classic Kaposi's sarcoma on the face. He presented with asymptomatic, erythematous papules on the nasal ala which had been noticed 2 months earlier. Histopathologic examination and nested polymerase chain reaction analysis in the tissue disclosed typical features of Kaposi's sarcoma.

Objectives: . To determine the appropriate anatomical borders of implantation on the temporal bone in a cadaver study, and to develop a simplified surgical technique for Baha Attract implantation through a small incision along the hairline using anatomical evidence and a navigation system. Methods: . In a cadaver study, 20 human adult dry skulls were used to find flat areas of the temporal bone for Baha Attract magnet implantation. Four borders of the “optimal surgical site” were defined: Asterion line, occipitomastoid suture line, sigmoid sinus line, and digastric groove line. In three patients, we implanted the Baha Attract according to the newly developed surgical procedure and validated the feasibility of this technique with a navigation system. Results: . We identified the appropriate position of the implant on the temporal bone, suggesting a simplified surgical technique for Baha Attract with a small incision. We determined the spot of implantation, and the implants were inserted through a small surgical incision (<2.5 cm) under local anesthesia; the procedure lasted approximately 30 minutes. Conclusion . The optimal surgical site of the temporal bone is a safe and easily accessible location for implantation of the Baha Attract.

We herein describe the case of a 34-year-old woman who presented with a painful, movable, subcutaneous nodule on the volar surface of her left fourth finger. She complained of lancinating pain when slight pressure was applied to the nodule. An excisional biopsy specimen revealed a contiguous, fusiform, nodular mass, measuring 0.2x0.5 cm, in the subcutaneous tissue. Histopathologic examination showed several well-circumscribed nodules in a plexiform pattern, composed of large polygonal cells with abundant eosinophilic granular cytoplasm. These cells were strongly positive for S-100 protein. We diagnosed this case as plexiform granular cell tumor.

BACKGROUND: Although venous lake is asymptomatic, treatment is usually performed for cosmetic purposes or to prevent bleeding after trauma. The treatment is diverse and includes surgical excision, compression and cryotherapy. Above all, sclerotherapy is a useful and effective procedure for the treatment of venous lake on the lip. OBJECTIVE: This study was undertaken to assess the effectiveness and complications of the sclerotherapy of venous lake on the lip. METHODS: Fifteen lesions from eleven patients with venous lake on the lip were treated with sclerotherapy using sodium tetradecyl sulfate, detergent sclerosant. According to the size of lesions, the volume of infused solution was varied and the effectiveness of treatment was evaluated after four weeks. RESULTS: After a single treatment, fourteen of the fifteen lesions(93.3%) were cleared completely. The remaining lesion was treated one additional time. There were no reported complications during treatment. CONCLUSION: Sclerotherapy is highly effective and safe for the treatment of venous lake on the lip and may be a promising treatment option.

BACKGROUND: The appearance of skin lesions at the dermatome of the nasociliary nerve in herpes zoster involving the ophthalmic nerve (Hutchinson's sign) was associated with an increased incidence of ocular complications. OBJECTIVE: This study is aimed to revaluate the clinical usefulness of the original concept of Hutchinson's sign in herpes zoster involving the ophthalmic nerve. METHODS: A total of 70 patients with herpes zoster, involving the ophthalmic nerve, were enrolled in this study at the medical center, Daegu Catholic University from December 2004 to July 2006. Statistical analysis using chi-sqaure test in verified the relationship between the clinical parameters and the development of ocular lesions (p<0.05). RESULTS: Statistical analysis showed that the presence of underlying disease, severity of pain, severity of skin lesions and Hutchinson's sign were the predictive factors of the development of ocular lesions. A strong relationship formed between the Hutchinson's sign and the development of ocular lesions [Relative risk: 6.769 (Confidence interval 95%: 2.310~19.838)]. CONCLUSION: Hutchinson's sign may be a useful predictive factor in the development of ocular lesions in the herpes zoster involving the ophthalmic nerve.

Multiple endocrine neoplasia type 2B (MEN 2B) is a rare disease caused by germline mutations in the RET proto-oncogene and is transmitted in an autosomal dominant fashion. It is characterized by medullary thyroid carcinoma, pheochromocytoma and mucosal neuroma developing in the tongue, lip, intestinal tract, palate etc. Among these neoplasias, mucosal neuroma generally develops from early childhood. Therefore, early detection and proper treatment can minimize the disease course. Here we describe a 9-year-old male who presented with multiple verrucous papules and nodules on his lips, tongue and gingiva that were there since birth. Histologic findings of his lips and tongue showed well-defined nerve bundles and DNA analysis revealed a M918T mutation at codon 918 of the RET oncogene. He was diagnosed early as having MEN 2B according to his genetic and phenotypic features.

Neurofibromatosis, like malignant melanoma, is believed to be a disorder of neural crest origin, but a definite association between these two diseases has not been established. We report a patient with malignant melanoma and with segmental neurofibromatosis. The malignant melanoma was not related to neurofibromas. Physical examination revealed no cafe-au-lait spots, axillary freckles, or Lish nodules. His family history was negative for neurofibromatosis or malignant melanoma.

A 31-year-old woman presented with 2 year history of multiple, pinhead-sized erythematous papules, which had become coalescent in linear arrangement from the forehead to the left nasal ala. Histopathologically, the lesion showed hyperkeratosis, spongiosis and inflammatory cell infiltration around the skin appendages, and was therefore diagnosed as facial lichen striatus. The patient had been treated with an intermittent topical steroid application for about two years, but this had not been effective. However, application of 0.03% tacrolimus ointment showed dramatic improvement.
