PURPOSE: To experimentally investigate the effect for muscle weakness after superior rectus Z-myotomy and histological changes. METHODS: Superior rectus muscle fibers of rabbits (16 rabbits, 32 eyes) were cut transversely with scissors across 75% of the muscle in two different positions on opposite sides. In group 1 (16 eyes), myotomies were performed at 2 and 7 mm from the muscle insertion (5 mm gap) and in group 2, performed at 2 and 5 mm (3 mm gap). The change of mark, eyeball position, and muscle tension after myotomy and 4 weeks postoperatively was evaluated, the location of the mark was examined, and muscle tissue biopsy was performed. RESULTS: After Z-myotomy, the marks of the two groups moved significantly posteriorly from insertion within groups (p<0.05), with no significant differences between groups (p=0.469). Eyeball positions of the two groups moved significantly inferiorly (p<0.05); the amount of position change of group 1 was greater than group 2 (p<0.05). When the globe was pulled in opposite directions for muscle action, the degree of change decreased with significant difference within groups (p<0.05), but there were no significant differences between groups (p=0.32). CONCLUSIONS: Z-myotomy of the superior rectus muscle affected the recession of eyeball position and weakened the muscle action. Muscle weakening affected by the different gaps between myotomies did not show consistent results.

Although it is commonly appreciated that there is an inordinately large number of anormalies associated with the excretory ducts of the liver, comparatively little attention has been paid to the position of the orfice of the common bile duct into the duodenum. But, obiviously the site of entrance of the common bile duct into the duodenum becomes of great importance to the endoscopist, radiologist, and surgeon in diseases of the extra-hepatic biliary tract diag-nostically and therapeutically. We report 'a case of anomalous termination of the common bile duct into the duodenal bulb with the gall bladder empyema.

Palisaded encapsulated neuroma (PEN) is a rare intraneural neuroma. It usually occurs as a solitary asymptomatic skin-colored papule, and commonly affects the butterfly area of the face of middle-aged adults. We report a case of PEN which developed on the right upper eyelid of a 30-year-old man. It was a 3 mm-sized skin colored papule, and histologically, there was a well- defined encapsulated nodule in the dermis, composed of spindle cells with basophilic and plump nuclei in a palisading pattern. On immunohistochemical staining, the tumor cells of the nodule were positive for S-100 protein, while the capsule of the nodule was positive for epithelial membrane antigen.

Primary cutaneous CD30-negative large T-cell lymphoma without prior or concurrent mycosis fungoides represents a distinct group of cutaneous T-cell lymphoma with an aggressive clinical behavior. Primary cutaneous CD30-negative large T-cell lymphoma is a rare disorder which represents only about 5% of primary cutaneous T-cell lymphoma. A 51-year-old woman presented with a rapid growing, ulcerative plaque on the right lower leg of 2 years duration. Histologically, it showed diffuse infiltrates with a predominance of medium-sized to large pleomorphic lymphocytes in the dermis and subcutaneous fat layers, which stained positively with CD3 and negatively with CD20, CD30, CD56 on immunohistochemical staining. There was no evidence of extracutaneous metastsis.
