Pretibial myxedema, which consists of localized cutaneous accumulations of acid mucopolysaccharides, oceurs in a few patients with hyperthyroidi';m after its correction by surgery or radioactive iodine therapy. We report a case of pretibial myxedema with exophthalmos in a 36 year old male. He has suffered from hyperthyroidism with bilateral pretibial myxedema for a period of 4 years. He was treated with a subtotal thyroidectomy and excision of both pletibia lesions 1 year ago. The lesions recurred on t,he left pretibial area, as a 11 X 16cm sized, non pitting, non tender, swollen, brownish plaque. The histopathologic findings showed epidermal hyperkeratosis and a considerable arnount of mucin in the mid-dermis. We treat.ed him with intralesional injection of triamcinolone acetonide with marked improvement.

Cutaneous horns of the penis are rare. We report a case associated with squamous cell carcinoma in a 56-year-old male. A gradually enlarging nodule had been on the glans penis for four years. He had suffered from an erythematous crusted tumor mass and horny excrescence on the glans penis which recurred and was aggravated after excision of the nodule seven months ago. Histopathologic findings of the lesions showed characteristic findings of squamous cell carcinoma and cutaneous horn. In situ DNA hybridization for human papillomavirus types 6, 11, 16, 18, 32, and 33 were all negative. The tumor mass were surgically excised and we have not found any sign of recurrence since then.

3.Histologic evaluation of low-intensity pulsed ultrasound effects on bone regeneration in sinus lift.
Journal of Periodontal & Implant Science 2010;40(6):271-275
PURPOSE: Many techniques have been described for achieving vertical augmentation of the maxillary sinus. The aim of this study is to evaluate the effect of low-intensity pulsed ultrasound (LIPUS) to enhance bone regeneration after sinus floor elevation. METHODS: The sinus lifting technique was performed through a lateral approach on 8 different sites of 5 patients (3 males and 2 females) and their mean age was 45.7 years old. The sites were randomly assigned to the control or test groups. The control group had 4 sites that received lateral sinus lifting procedure only, while the test group had 4 sites that received LIPUS application after the lateral sinus lifting procedure. 24-32 weeks (an average of 29 weeks) postoperatively, new bone formation in the augmented sinus sites was evaluated through histologic and histomorphometric analyses of the biopsy specimens obtained during implant placement. RESULTS: In the test group, the mean percentage of newly formed bone was 19.0+/-2.8%. In the control group, the mean percentage of newly formed bone was 15.2+/-3.1%. The percentage of newly formed bone was approximately 4% higher in those cases where the sinus was treated by LIPUS than the percentage in those cases where it was not used. The difference was statistically significant. CONCLUSIONS: Within the scope of this study, low-intensity pulsed ultrasound application after sinus lifting appeared to have a significant effect on the development of new bone formation.

Bart's syndrome was initially described as a genodermatosis characterized by congenital localized absence of the skin with blistering and nail deformities 1-3. However, it is considered as any type of epidermolysis bullosa(EB) with localized congenital absence of the skin on the extremities. A 33-day-old fbmale baby was presented with congenital absence of the skin over the left shin and dorsa of both feet which were covered with the thin, translucent, and brown-red glistening membranes. Blistering of the right calf and left great toe nail deformity were also noted. She was diagnosed as a recessive dystrophic EB by the histopathological, ultra- structural and immunomapping studies.

Leukemia cutis are clinically divided into the specific and nonspecific types. The former demon strates a malignant cell infiltrate on histopathologic examination. We report a case of leukemia cutis in a 29-year old female which developed specific cutanous manifestations previous to peripheral blood abnormalities, She had suffered from several discrete, bean to walnut sized, tender, erythematous patches and nodules on the trunk for 3 months and these gradually spread to the right cheek and upper arm. Atypical lymphocytes and incesassed lymphoblasts were notifced on a peripheral blood smear and bone marrow aspiration. A bone marrow biopsy revealed compact marrow finding, and increased celluarity. The histopathlogic findings showed diffuse dermal and subcutaneous infiltration of atypical lymphocytes. An immunohistochemical study with kappa, lamda, and leukocyte common antigen(LCA) revealed lymphoid malignancy, T-cell type. We treated her with various combined chemotherapy for 2 year, but her skin lesions were not inproved.

Adult T-cell leukemia/lymphoma (ATLL) is an often aggressive and fatal malignancy of mature CD4+ T lymphocytes, characterized by leukemia, lymphadenopathy, hypercalcemia and lytic bone lesions. Diagnosis of ATLL is based cm abnormal T lymphocytes in the peripheral blood and histologically and cytologically proven lymphoid malignancy with T cell surface antigens. Anti-HTLV-I serum antibodies and demonstration of clonality to HTLV-I proviral DNA are included. We report a case of ATLL in a 64-year-old man who had a painful nodule on the right cheek and multiple scattered papules and nodules on the trunk for 2 months. He had multiple cervical and axillary lymph node enlargements and hepatosplenomegaly. On laboratory finding peripheral leukocytes count was 33,400/mm3 with 63% atypical lymphocytes. Clover-shaped lyrnphocytes with multilobulated nuclei were found in peripheral blood and bone marrow. Histologic findings showed dense bandlike infiltrations of atypical lymphocytes in the dermis with angiocentricity. The surface phenotype of these abnormal cells were CD2+, CD3+, CD4+, CD30+ and HLA-DR+ and HTLV-I specific antibodies were found.

An 82-year-old male patient was admitted for neck pain, motor weakness in both upper extremities, and gait disorder. The patient had no history of rheumatoid arthritis or other specific histories, and the findings of cervical myelopathy with retro-odontoid pseudotumor were confirmed by cervical magnetic resonance imaging. On cervical radiography, there was no evidence of atlantoaxial instability or subluxation. Therefore, posterior fusion was not performed; only a C1 laminectomy was performed. Immediately after surgery, the pain decreased, and neurological symptoms were also improved. In the case of a retro-odontoid pseudotumor without atlantoaxial instability, it is believed that the symptoms can be improved only with C1 laminectomy.

PURPOSE: Stress distribution and mandible distortion during lateral movements are known to be closely linked to bruxism, dental implant placement, and temporomandibular joint disorder. The present study was performed to determine stress distribution and distortion patterns of the mandible during lateral movements in Class I, II, and III relationships. METHODS: Five Korean volunteers (one normal, two Class II, and two Class III occlusion cases) were selected. Finite element (FE) modeling was performed using information from cone-beam computed tomographic (CBCT) scans of the subjects' skulls, scanned images of dental casts, and incisor movement captured by an optical motion-capture system. RESULTS: In the Class I and II cases, maximum stress load occurred at the condyle of the balancing side, but, in the Class III cases, the maximum stress was loaded on the condyle of the working side. Maximum distortion was observed on the menton at the midline in every case, regardless of loading force. The distortion was greatest in Class III cases and smallest in Class II cases. CONCLUSIONS: The stress distribution along and accompanying distortion of a mandible seems to be affected by the anteroposterior position of the mandible. Additionally, 3-D modeling of the craniofacial skeleton using CBCT and an optical laser scanner and reproduction of mandibular movement by way of the optical motion-capture technique used in this study are reliable techniques for investigating the masticatory system.
