Hemangiopericytoma is a rare vascular tumor that usually occurs in adults. The tumor is believed to originate from pericytes that are closely related to the capillary walls. Congenital hemangiopericytoma is a more rare disease that occurs in approximately 0.03% of all heamngiopericytomas. Herein, we describe a 1-month-old male newborn with huge congenital hemangiopericytoma in the retroperitoneum that exhibited a typical morphological vascular pattern.

Giant congenital melanocytic nevi are very rare skin lesions with an estimated prevalence of 1 in 20,000 live births, and have high risk of malignant melanoma development and leptomeningeal melanocytosis. Hence, its early and exact diagnosis in the neonatal period is important and essential. Only seven cases of giant congenital melanocytic nevi have been reported in Korea, of which none of the cases were associated with hemangioma. Herein, the authors describe a case of giant congenital melanocytic nevi with huge hemangioma with the patho logic findings that exhibited benign and provide a literature review.

Human placenta contains various kinds of nutritional elements essential for embryonic development. Currently, human placenta extracts are widely overused in Korea to improve certain health conditions (postmenopausal syndrome, liver function, and cosmetic purposes) without scientific evidence that they actually work. The use of placenta extracts should be restricted, due to a lack of systematic research on the therapeutic effectiveness and adverse results from these treatments. While the common adverse effects that have been reported are fever, rash, itching, nausea, vomiting, breast pain, and rare cases of anaphylactic shock, there have been no reports of pulmonary complications such as hypersensitivity pneumonitis. Recently, we experienced a patient with hypersensitivity pneumonitis following a placenta extract injection. To our knowledge, this is the first case of hypersensitivity pneumonitis associated with placenta extract use.

저자들은 악성 흑색종의 원발 부위로 흔치 않은 폐 악성 흑색종 환자에서 원발 부위의 수술적 치료 및 전이 부위에 대한 수술적 치료와 보조적 치료를 통해 생존기간을 연장시킨 증례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Melanoma develops in the skin or the mucosa of organs. It spreads via lymphatic channels or the bloodstream to the regional lymph nodes or organs such as the brain, liver, and lung. Melanoma of the lung is nearly always metastatic, and primary malignant melanoma of the lung is very rare, with only 30 cases reported in the English literature. The possibility of skin lesions that have disappeared, or of undetected primary sites, makes it difficult to confirm true primary tumors. Therefore, a thorough workup is needed to make the diagnosis. Since metastatic melanoma is incurable, the goal of treatment is palliation. However, because of the rare experience of primary melanoma of the lung, it is difficult to predict the prognosis. We experienced one patient with primary malignant melanoma of the lung with metastases who had been managed with surgery, interferon-a, chemotherapy, and radiation therapy over 5 years. This case report presents the diagnosis and management of primary malignant melanoma of the lung. (Korean J Med 76:238-243, 2009)

Lesch-Nyhan disease is a very rare X-linked recessive disorder characterized by mental retardation, spasticity resembling cerebral palsy, choreoathetosis, self-mutilation and hyperuricemia. Self-mutilative behavior is a hallmark of the disease. The underlying defect is a deficiency of hypoxanthine-guanine phosphoribosyltransferase (HPRT). We report on a fourteen-year-old boy, who manifested gouty arthritis and mild renal insufficiency with Lesch-Nyhan disease, lacking self-mutilative behavior in spite of undetectable HPRT activity. Though there were several reports about some cases of Lesch-Nyhan disease in the past Korean literature, the cases were classic forms with definite neurological manifestation. As far as we know, this is the first case of Lesch-Nyhan disease without self-mutilation in Korea.
