Positron emission tomography (PET) with 2-[F-18]-Fluoro-2-deoxy-D-glucose (FDG) was performed in ninteen patients who had benign musculoskeletal tumors in order to determine if there was a relationship between histologic grade of tumor and FDG uptake of tumor. These patients had been evaluated previously with computed tomography (CT) or magnetic resonance (MR) imaging or both. The diagnoses were confirmed with incisional or excisional biopsy or by radiographic follow-up. Generally high-grade tumors had significantly greater uptake of FDG than low-grade lesions . Benign lesions such as giant cell tumor, fibrous dysplasia, and osteofibrous dysplasia showed significant elevation of SUV (Standardized Uptake Value) above 4.0. On the contrary. The current studies suggest the utility of FDG-PET imaging as an adjunct to CT or MR imaging in the evaluation of benign tumors. And results of PET suggest benign tumors with high SUV are histologically active lesion and tend to be locally aggressive.

We report a case of atrophoderma vermiculata with an unusual location. Besides symmetrical small pitted macules and linear atrophic depressions on both cheeks, there were unilateral atrophic depressed macules on the forehead, the right popliteal fossa and left up-per arm in our case. The histopathologic findings of these lesions showed a slight degree of epidermal atrophy with follicular pluggings and flattened rete ridges. In the dermis, there were mild perivascular in-filtrations of mononuclear cells. In addition, we could find out no pilosebaceous unit and other adnexal structures were diminished in number.

Molluscum contagiosum is a common, benign, viral disease of the skin and mucous membrane that generally affects children. This disease is characterized by a 2 to 7 week incubation period; the involvement of the face, trunk, and extremities; spontaneous resolution within 2 to 4 months; and common autoinoculation. Individuals are susceptibile from the age of one. Herein, we report a case of molluscum contagiosum with an unusual manifestation. The skin lesions, which occured at ten days postpartum, showed two adjacent hard papules on the posterior scalp. They remained for 8 months in the same size and number.

An 18-year-old man had suffered from intense burning with redness and an increased temperature of both the lower legs, forearms and hands since the age of 5. Symptoms were exacerbated by exposure to heat or walking. The patient obtained temporary relief by immersing his feet and hands in cold water. We observed the increase of skin temperature in relation to pain by thermography. No specific abnormalities were noted in laboratory studies. Treatment with aspirin was ineffective. We report a rare case of primary erythermalgia with typical features.

We report a rare case of sporadic keratosis punctata palmaris et plantaris in a 49-year-old woman. Thirty years ago, firm semitranslucent papules developed on the middle portion of her palms without any subjective symptom. The lesions had flat-topped smooth surfaces. They were concentrated along the margins of the hands, especially on the lateral surfaces of both index fingers and finger tips/ Ten years ago, similar hyperkeratotic papules with or without central craters developed on the weight bearing portions of her soles. Her family and past histories were negative. The biopsy specimen revealed a dense hyperderatotic stratum corneum which fitted into a cup shaped depression in the stratum malpighii and a turning inward of the rete ridges at the margin. The Masson trichrome and elastic strains showed no peicific dermal changes.

From January 1985, to June 1986, 7 cases in which supracondylar and intercondylar fractures of the femur were treated at our orthopaedic department using the Extensile Approach for an anatomical reduction and firm internal fixstion, show successful results in follow up stuides. l. All 7 cases were type III fractures of Neers classification. 2. Among the 7 cases treated surgically using the Extensile Approach, 5 cases showed excellent and good results and the remaining 2 csses showed one fair and one failed results. 3. Probably due to the additional open proximal tibia and patella fracture and delayed surgery from trauma one case had a fair results. The case which failed wss due to ipsilsteral ligamentous injuries and a nerve injury in addition to the femur fracture and slso the impossibility of early knee joint exercise due to associated injuries. 4. None of the results of the 7 csses had any relationship with the patients age. 5. One case of postoperative skin necrosis developed around the tibial tuberosity and was treated successfully by a cross leg flap. 6. In comminuted supracondylar and intercondylar fractures of the femur, the Extensile Approach is thought to be an excellent surgical technique by means of a wide surgical field for an anatomical reduction and firm internal fixation with the repair of associated ligamentous injuries.

Congenital pseudarthrosis of the tibia was accepted as one of the most difficult disease in respect of the frequency and treatment for the orthopaedists. Since April, 1984, we experienced 3 cases of congenital pseudarthrosis of the tibia, one 2 year-old boy involved left tibia only and the other 4 year-old female involved bilaterally, obtained solid bony union in all which were treated by massive surgical management that contained vascularized bone graft and electric stimulation. Several complications were faced such as refracture, valgus deformities of the ankle, skin irritation sign, angular deformities. But refracture was healed without delayed or nonunion by simple plaster cast immobilization. The vascularized bone graft snd electric stimulation is thought to be more improved methods for the treatment of congenital pseudarthrosis of the tibia. Althought solid bony union was obtained in congenital pseudarthrosis of the tibia, periodic follow-up and adequste management must be mandatory up to the end of the bony growth.

We report two cases of malignant lymphoma of mucosa-associated lymphoid tissue arising in the conjunctiva. Case 1, an 18-year-old girl, showed her left lower conjunctival swelling for four months and Case 2, a 29-year-old man, showed similar lesions on both his eyes for one year. Histologically, both cases revealed monomorphous dense lymphoid infiltrates invading the overlying conjunctival epithelium with diffuse patterns. The infiltrates were composed of small lymphocytes admixed with centrocyte-like cells within the conjunctival epithelium and stroma in association with B-cell lineage. No relapse was noted during the period of about 1½ years follow-up in case 1 treated by local excision only and in the follow-up period of 2 months in case 2 treated by local excision and subsequent chemotherapy.

A 34-year-old man visited our hospital with alopecia areata on the occipital scalp, which began to develop two months prior to his visit. He was sensitized with 0.2% diphenylcyclopropenone(DPCP) in acetone that was applied to the inner side of his right arm. Two weeks after sensitization, we applied DPCP on his bald lesion once weekly for skin challenge. Following the third application of DPCP, polycyclic erythematous target-like lesions developed around the sensitized area. A clinical diagnosis of erythema multiforme was made. Histologically, the target-like lesion showed few eosinophilic dyskeratosis, exocytosis, and hydropic de-generation of basal layer in the epidermis, and mononuclear infiltration around superficial blood vessels in the dermis. We report herein a rare case of erythema multiforme following topical application of DPCP in the treatment of alopecia areata. This complication must be noted because of the wide-spread and frequent use of DPCP in dermatotherapeutic fields.

Genital melanosis is an acquired, irregular, brown to black discoloration of the glans or shaft of the penis, or of the vulva and vagina. Although genital melanosis seems similar to malignant melanoma clinically, the histologic findings of genital melanosis show basal layer hyperpigmentation with or without melanocytic hyperplasia and no atypia of the melanocytes. We report a rare case of genital melanosis ; a vulvar melanosis.
