Cutaneous or subcutaneous metastases occur in 2% to 9% of visceral malignancies. Skin metastases are seen most commonly from carcinomas of the breast, lung, large intestine. Skin metastases of prostatic origin are quite uncommon and preferentially localized to the lower abdomen and genital area. Two cases of cutaneous metastases of prostatic origin have been reported in the Korean dermatological literature in our review. We report a case of cutaneous metastases from prostatic cancer

Nevus lipomatosus superficialis is a fairly uncommon disease characterized by ectopic fat tissue in the dermis. Lesions most commonly occur on the lower trunk, especially on the back, buttocks or abdomen. Rarely, lesions also occur on the knee, axilla, arm, ear and scalp. To our knowledge this is the first case of nevus lipomatosus superficialis developing on the dorsal foot.

PURPOSE: This study was performed to evaluate the efficiency of Platelet-rich plasma (PRP) for acceleration of bone healing process on allograft transplantation after curettage in benign bone tumor. MATERIALS AND METHODS: From December 2007 to February 2009, twenty-one patients who had benign bone tumor and underwent allograft transplantation after curettage were evaluated. Mean follow-up period was 14.6 months (range, 12-26 months). We compared with 13 cases of PRP group and 8 cases of non-PRP group in terms of size of lesion, bone resorption, amount of applied PRP and complications. The mean age at surgery was 23.6 years (range, 4-73 years). The most common diagnosis was simple bone cyst (7) followed by enchondroma (4), giant cell tumor (3), undifferentiated benign bone tumor (3) and so on. RESULTS: The mean size of lesion was 33.5 cm3 (range, 2.3-181.9 cm3) (29.4 cm3 in PRP group and 40.2 cm3 in non-PRP group). The mean volume of injected PRP was 7.4 cc (range, 3-12 cc). Bone union started at 3.0 months (range, 1.5-5.8 months) in PRP group and 5.3 months (range, 4-8 months) in non-PRP group. Three cases for each group were excluded due to recurrence and pathologic fracture. One patient had febrile episode 3 weeks later after surgery which subsided with antibiotics. CONCLUSION: The PRP could accelerate bone union in allograft transplantation after curettage of benign bone tumor. Furthermore, we expect that PRP can accelerate bone union in fracture or non-union.

Fifty percents of patient with achondroplasia present neurological disturbances of varying degree. Congenital narrowing of the spinal canal in achondroplastics seems to be the main cause of the cord disturbance, and there are several other causes such as prolapse of intervertebral discs, spondyloarthitic degenerative manifestations and wedging of vertebral body. Surgical treatment of the cord disturbance consist of anterior decompression with fusion and posterior decompression. We experienced L1-2 disc herniation in achondroplasia with rapid progression of neurologic symptoms and treated with posterior decompression. Two years after operation, the patient had good result.

Operations on the inner aspect of the pelvis are often necessary for irreducible fracture of the ilium, irreducible fracture of superior and medial portion of the acetabulum, tumors and infections involving iliac fossa, and fracture-dislocation and infection of the sacro-iliac joint. Until now Letournel and Judet's ilioinguinal and iliofemoral approaches provided access to anterior column of the pelvis by elevating muscle layer on inner aspect of the pelvis. We used modified iliofemoral approach using ASIS(anterior superior iliac spine) osteotomy to gain better access to anterior column, the pelvlc brim, and in some occasions as far as anterior sacroiliac joint while avoiding injury to the structures in the inguinal ligament and lateral femoral cutaneous nerve and reported six cases treated with this approach. In conclusion, a modified iliofemoral approach using ASIS osteotomy is a useful approach which can obtain an excellent exposure in the inner pelvis.

There are several considerations in performing free vascularized fibular graft for the treatment of the large bone defect, e.g., bone fixation, additional bone graft, and management of complication. Authors have analyzed 25 cases treated with free vascularized fibular graft at Holy Family Hospital between Jun. 1985 and Dec. 1994. The mean follow up was 27.4 months The results were as follows: 1. The causes of the defect were traumatic defect with infection of 16 cases, bone tumor of 4 cases, congenital pseudoarthrosis of tibia of 3 cases and osteomyelitis of 2 cases. 2. Hypertrophy of the graft was more common in the lower extremity and in the patient under the age of 15. 3. Nonunion of graft occurred in 4 cases(16%). These cases were fixed with screws and/or pin ini tially and subsequently treated with rigid internal fixation. 4. Stress fracture of graft occurred in 3 cases(12%). Two cases of them were treated with internal fixation. 5. Additional bone graft were performed in 6 cases(24%), among 17 cases who had bone defect of lower extremity in adult. In conclusion, authors emphasize that rigid internal fixation and additional bone graft in performing free vascularized fibular graft are recommended for obtaining early solid bony union and achieving early rehabilitation.

Incidence of non-contiguous multiple spine fracture was increased from 3.2%~4.5% at 1960th and 70th to 5.7% ~23.8% at 80th and 90th. But there is no reports in Korea which has high incidence of traffic and industrial accidents. In 345 consecutive patients with acute spine fracture, we found that 43 patients (12.5%) had multiple non-contiguous spine fractures. At the 43 patients studies 37 (87.4%) sustained fractures at 2 levels while 6 had more than 3 levels of injury, 26 were injured by fall from heights, 27 (62.8%) had 2.33 associated injuries on an average, and 12 (27.9%) had a neurologic deficit. There are five patterns account for 26 (50%) of the total number of patients. In 19 patients (44.2%), there was a mean 29.3 days delay (from 3 to 233 days) in diagnosis of the minor lesions. In 19 delay diagnosed minor lesions, it confirmed by bone scan in 12 patinets(63.6%). Two patients died within 24 hours after accident, and 41 patients (41 major and 50 minor fractures) were treated in our hospital. Among them, 21 (51.2%) needed modification of treatment by the presence of non-con- tiguous multiple spine fractures. According to above findings, the physician must be aware of the possible noncontiguous multiple spine fractures when examine and treat the patients with spine fracture.

Hepatoblastoma (HB) is a rare embryonic malignant tumor of the liver. Most morphological studies on HB have limited to the histological characteristics and only 3 cases of HB have been described in the cytology literature. We present 2 cases of HB occurring in children aged 1 year and 3 years, respectively. The distinctive cytologic features of fine needle aspiration of HB were clusters of tumor cells showing acinar and trabecular pattern, smaller tumor cells with a high nuclear-cytopalsmic ratio and hyperchromatic nuclei having prominent nucleoli, and the presence of extramedullary hematopoiesis and osteoid material. These features were also found in the cell block and the biopsy specimen, and appeared very useful in the differentiation of HB from hepatocellular carcinoma.
