Leiomyosarcoma arising in the skin is rare tumor, and diagnosis usually is made microscopically. After local excision, these lesions recur in large proportion of pat ients. The authors herein report a 53-year-old male with leiomyosarcoma appeared in the skin of the right forearm and presenting as a dark reddish colored, 5*6cm in diameter, superficial ulcerated single firm nodule with intermittent pain. Histopathological examination showed poorly circumscribed tumor consisting of interlacing bundles of spindle shaped smooth muscle cells in the middle and lower parts of the dermis. The nuclei were hyperchromatic, large, vacuolated, and irregular in shape. Electron microscopic findings revealed cytoplasmic organelles such as rough endoplasmic reticulum and mitochondria of malignant smooth muscle cells in the paranuclear area, Characteristic subsarcoelmmal caveolae and dense plaque were noted and myofilaments were distributed in the peripheral cytoplasm. The tumor did not recur in 10 months' follow-up.

Recurrent deformity following hallux valgus surgery can be technically challenging to treat. In cases of revision surgery, a surgical technique with greater corrective power is often chosen compared to the primary surgery. Therefore, minimally invasive surgery is not commonly performed. On the other hand, minimally invasive surgery minimizes soft tissue damage and allows for greater correction of deformity compared to traditional open approaches. This paper reports four cases of recurrent hallux valgus treated with a minimally invasive distal transverse metatarsal osteotomy – Akin osteotomy (MITA), resulting in significant improvements in the clinical and radiographic outcomes.

BACKGROUND AND OBJECTIVES: Angiogenesis is the process of new blood vessel development from preexisting vessel. In many human solid tumor, the extent of angiogenesis is one of the most significant prognostic factors that can be used to predict the patient survival rate and metastasis. The aim of this study is to investigate the role of new blood vessel formation in the thyroid tumors. SUBJECTS AND METHOD: We analyzed the microvascular density and proliferation index in the 70 cases of thyroid tumors by double immunohistochemistry with anti-CD34 and anti-Ki67 antibody. The microvascular density and Ki67 index were compared with the clinical parameters such as sex, age, stage, tumor extension, cervical lymph node metastasis, and prognostic factors, which were obtained through the retrospective review of the medical records. RESULTS: The microvascular density and Ki67 index were higher in malignant tumors than in benign tumors. Higher microvascular density and Ki67 index were associated with tumor stage and increased risk of AMES, AGES and MACIS scores. CONCLUSION: The microvascular density and Ki67 index may serve as significant prognostic factors in the differentiated thyroid cancer.
