Since Palmer's introduction of the torn medial collateral ligament, many clinical and anatomical studies were performed. But any reconstructive procedure of the medial collateral ligament of the knee known to us, has not solved the problem completely yet. The purpose of present study is to describe a technique of reconstruction, socalled Tatsuzawa's tenodesis surgery of transposed semitendinosus tendon, and is to report the clinical results of 45 cases treated by his procedure between April 1976 and June 1981. In addition, significance of the procerdure was compared with the result of primary closure group of the torn ligament. Tatsuzawa's procedure consists of reinforcement surgery of the repaired or unrepaired torn medial collateral ligament with forwardly transposed semitendinosus. The semitendinosus tendon was brought forward to lie adjacent to deep layer of the medial collateral ligament. The transposed part of the tendon was sutured throughout its length to the medial collateral ligament and to the medial aspect of the tibia and femoral condyle. Because the direction of transposed tendon as similar to the direction of fibers of medial collateral ligament, the procedure was very simple and anatomical one, and had some functional advantages. In this series some old cases are treated only with tendon reinforcement operation without repairing the laxed torn ligament. The results of the surgery were evaluated by the Asais modification of the Feltons evaluation criteria. Results obtained were as follows: 1. In semitendinosus tenodesis with or without primary repair of the torn ligament, satisfactory results were obtained (excellent and good) in 33 cases (73.3%). But in 20 cases of the primary repair group, the satisfactory results were obtained in 11 cases (55%). More satisfactory results were obtained with the semitendinosus tendon reinforcement operation of the torn ligament than only with primary repair. 2. In 29 cases with fresh injury of the medial collateral ligament in which the primary repair together with the tendon reinforcement procedure was performed, satisfactory (excellent and good) results were obtained in 72.4% (21 cases), and in 16 untreated old cases in which only the tendon reinforcement procedure were done, satisfactory results were obtained in 75%. 3. In 5 cases having medial collateral and anterior cruciate ligaments tear, excellent results were obtained in 3. This explains that semitendinosus tendon reinforcement procedure is the key one of the reconstructive operative procedures. It is thought that the procedure is also effective for the anterior cruciate tear to provide the anterior instability.

Nucleolar organizer regions (NORs) are loops of DNA which occur in the nucleoli of cells which possess ribosomal RNA genes. The numbers and areas of NORs have been thought to be related to cellular activities. We aimed to investigate the direct relationship between the parameters of AgNORs and cellular proliferative activity using immunohistochemical method with the monoclonal antibody Ki-67, which demonstrates proliferating nuclei. The sequential technique for the simultaneous Ki-67 immunostaining and NOR staining was applied to the same slides of a series of non-Hodgkin's lymphomas (NHL) of the low, intermediate, and high grade type. The number of AgNOR per cell was counted and mean NOR percentage nuclear area (NPNA) was measured by morphometry in both the Ki-67 positive and Ki-67 negative nuclei. The increased immunoreactivity for Ki-67 was found in the high grade than in the low grade non-Hodgkin's lymphoma. This was reflected in the two areas of the palatine tonsils and lymph nodes, the positive cell counts being higher in the follicle center nuclei than in those in the interfollicular compartment. In general the numbers and NPNA of AgNORs were higher in the Ki-67 positive nuclei than in those lacking the antigen in malignant lymphomas as well as in control. The AgNORs numbers and NPNA in controls were the highest in the Ki-67 positive cells in the follicular area and the lowest in the Ki-67 negative cells in the perifollicular area. In malignant lymphomas the numbers and NPNA of AgNORs tended to increase in proportion to their grade in both the Ki-67 positive and negative cells. The numbers of AgNORs of the high grade and the NPNA of the intermediate and the high grade were significantly higher in Ki-67 positive cells than in Ki-67 negative ones. With this double staining method it was now possible to confirm that numbers and NPNA of AgNORs were directly related to the cellular proliferative activity. In maligant lymphoma, among the several parameters of the AgNORs, NPNA in Ki-67 positive cells is proposed to be the most useful marker in determining the prognosis of the patient.

A case of invasive cribriform carcinoma of the breast is presented with fine need- le aspiration cytologic features. The aspiration was performed from a papable 2.0cm mass in the upper outer quadrant of the right breast in a 53 year-old woman. The aspirate showed cellular smear composed of larger three dimensional tight clusters, smaller monolayered loose clusters, and many individual cells on the clean background. In the clusters, the tumor cells were bordering central lumina, quite similar to the cribriform in histology. The tumor cells in the clusters and individual tumor cells had uniform, small and round nuclei. The chromatin was finely granular, and nuclear membrane was smooth. No discernible nucleoli were present (nuclear grade 1-2). Unless the abundance of individual cells and the cribriform growth pattern are recognized in the smear, the cytologic diagnosis of invasive cribriform carcinoma is difficult.

The dendriform pulmonary ossification (DPO) is a rare condition of unknown origin in which branching mature bony spicules, usually containing marrow, are found within the alveolar septa. DPO manifests slow progression over many years or may remain unchanged; spontaneous regression has not been recorded. Most patients have no symptoms directly attributed to the ossification, although they may have symptoms due to the underlying fibrotic process. We experienced a case of DPO in 38 year-old-man who presented with cough and sputum for a month. The chest X-ray showed marked coarsened interstitial lung markings in both lungs, especially in the lower lobes. Open lung biopsy was done. Grossly, there were significant dendriform osseous structures. Histologically, branching arrays of mature bone were found in the interstitium and occasionally in alveolar spaces. Some bony trabeculae contained fatty or cellular marrow. The alveolar septa showed fibrous thickening with chronic inflammation. The transition between fibrosis and bone tissue was observed. Our case suggests that dendriform pulmonary ossification may be a rare special manifestation of chronic fibrosing interstitial inflammation of the lung. Osseous structures seem to derive from metaplastic bone formation in the vicinity of undergoing fibrous process.

Myofibrosarcoma of the breast is a rare malignant mesenchymal tumor that has been reported in only four well documented cases so far. We report a case of myofibrosarcoma of the breast in an 88-year-old man who complained of a palpable mass for 1 year. Microscopically, the tumor consisted mainly of spindled cells, arranged in irregular fascicles and embedded in broad bands of dense hyalinized collagen. It showed ill-defined border infiltrating the adjacent adipose tissue, moderate cellular pleomorphism, and high mitotic rate (8~9/10 HPF). Immunohistochemical study confirmed myofibroblastic differentiation of the tumor cells with diffuse strong reaction for vimentin, smooth muscle actin, and fibronectin.

Angioma serpiginosum is a rare vascular naevoid disorder due to progressive ectatic dilatation of capillaries in the papillary dermis. We report two cases of angioma serpiginosum. A 24-year-old woman presented with asymptomatic multiple deeply red macules arranged in a serpiginous pattern on the left posterior thigh. In the other case, an 8-year-old girl had asymptomatic red nonpalpable puncta that were grouped closely together in a linear pattern from the left lower abdomen to thigh. On the histopathological examination, both cases commonly showed grouped, dilated, ectatic vessels in the upper dermis. These clinical and histopathological findings were typical of angioma serpiginosum.
