A 67-year-old man noted a 4×6cm sized, erythematous, erosive, oozing patch on the penile shaft, which resisted conservative therapy for three years. Histopathologic examination revealed typical findings of extramammary Paget's disease. Interestingly, nests of Paget's cells in some hair follicular structures were shown in the middermis. The lesion was excised by microscopically controlled excision, using the fresh-tissue technique. There were histologically involved areas extending to quite a distance beyond the clinically normal appearing skin. Mohs micrographic surgery might offer the unique advantage of effective surgical treatment with microscopically controlled tumor free borders in the extramammary Paget's disease.

BACKGROUND: Keloids and hypertrophic scars are benign fibrous growths which usually occur in predisposed individuals after trauma. Numerous modalities have been used to treat keloids and hypertrophic scars, but the final results have been so far unsatisfactory. OBJECTIVE: The purpose of tlis study was to evaluate the effect of the combination of cryosurgery and intralesional corticoster oid for treatment of these scars. METHOD: Thirty patients, aged 17 to 45 years old, with keloids or hypertrophic scars(mean duration, 6.4 years) were treated using solid CO2 followed by intralesional injection of triamcinolone acetonide(13.3 mg/ml). Two freeze-thaw cycles per lesion were employed. Freezing time was chosen arbitrarily from 7 to 20 sec depending on the characteristics of each scar. RESULTS: The results are summarized as follows. 1. Excellent and good results were achieved in 57% of all subjects on average, 77% of those who were treated more than 3 times, and 48% of those treated less than twice. 2. The keloid of less than 2 years duration showed better results than older ones. 3. No recurrence was seen in 63% of patients, but partial recurrence in 21% of patients and complete recurrence in 10% were observed. Lesions on the trunk showed less improvement (p<0.05) and were more recurrent than other lesions. 4. There were complications in 9 patients, such as hyperpigmentation(6), hypopigmentation(1), infection(1) and telangiectasia(1). CONCLUSION: Cryosurgery and intralesional corticosteroid injections produced synergistic advantages. A cornbination of these modalities might be an effective treatment modality in keloids and hypertrophic scars.

A 34-year-old Korean man presented with a 3 week history of a yellowish eczema like patch on the left thigh. Sixteen months prior, he was diagnosed with polymorphie r eticulosis of the left nasal cavity. The patient, refuse<3 conventional radiation therapy and took herbal medication and diet therapy instead. Biopsy of the nasal cavity, hard palate and left thigh lesians showed extensive necrosis and polymorphic infiltrates of atypical lymphocytes with angiodestructive invasion. Irnmunohistochemical study of left thiyh lesion showed strong CD2 positivity con sistent with the diagnosis of peripheral T cell lymphorra.

OBJECTIVE: Fragile X syndrome is the most common form of familial mental retardation, attributable to (CGG)n expansion in the FMR1 gene. This study was undertaken to ascertain the distribution of FMR1 CGG repeat in the general Korean women and to identify ethnic difference in FMR1 CGG repeat number. Material and METHOD: Between January 1999 and December 1999, we evaluated 1,000 low risk women who visited Gachon Medical School Hospital. DNA samples were extracted from the venous bloods by routine methods, and G-C specific Polymerase Chain Reaction (PCR)s were performed to evaluate FMR1 CGG repeat number. RESULTS: Mean FMR1 CGG repeat number was 26.9 (6-50), single PCR bands were detected in 776 cases (77.7%). There were two more bands in 22.3% of the cases. Most of the cases are located between 21 and 35 repeats, especially 21-25 repeats. The pattern of distribution of CGG repeat is dispersed. In 13 cases, we could not obtain the PCR results. CONCLUSION: Low risk of transmission rate of the FRX in Korea can be expected.

We report a case of dysplastic gangliocytoma of the cerebellum(Lhermitte-Duclos disease) that can cause progressive mass effect in the posterior fossa. Cowden disease is a rare autosomal dominant disorder characterized by mucocutaneous hamartoma and high incidences of systemic malignancies. The patient had no mucocutaneous lesions indicating Cowden disease. With recent advances in molecular genetics, the association between Lhermitte-Duclos disease and Cowden disease has been recognized, it is considered that Cowden disease is a new phakomatosis. Recognition of this association has direct clinical relevance and long term follow up may lead to the early detection of malignancy.

The authors defined precaval retropancreatic space as the space between pancreatic head with portal vein and IVC analyzed the CT findings of this space to know the normal structures and size in this space, We evaluated 100 cases of normal anbdominal CT scan to find out normal anatomic structures of precaval retropancreatic space retrospectively. We also measured the distance between these structures and calculated the minimum, maximum and mean values. At the splenoportal confluence level, normal structures between portal vein and IVC were vessel (21%), lymph node (19%), and caudate lobe of liver (2%) in order of frequency. The maximum AP diameter of portocaval lymph node was 4mm. Common bile duct(CBD) was seen in 44% and the diameter was mean 3mm and maximum 11mm. CBD was located in extrapancreatic (75%) and lateral (60.6%0 to pancreatic head. At IVC-left renal vein level, the maximum distance between CBD and IVC was 5mm and the structure between posterior pancreatic surface and IVC was only fat tissue. Knowledge of these normal structures and measurement will be helpful in differentiating pancreatic mass with retropancreatic mass such as lymphadenopathy.
