1/5. A case of pelvic lipomatosis presenting with edema of the lower extremities.We report a 29-year-old male with pelvic lipomatosis that presented with edema of the lower extremities. The patient visited our department because of the marked edema of the lower extremities with body weight gain. The pelvic region was generally radiolucent on plain abdominal radiogram. Excretory urogram and pelvic computed tomography scan revealed compression of the bladder by an adipose tissue mass. On lymphograms, lymph vessels were compressed from the inguinal area in the common iliac region. The edema of the lower extremities was thought to be caused by lymph vessel obstruction.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/5. Congenital infiltrating lipomatosis of the face: report of cases and review of the literature.Three cases of infiltrating congenital lipomatosis of the face are presented. These lesions shared the following morphologic criteria: 1) nonencapsulated congenital fatty tumor; 2) infiltration of adjacent muscle and soft tissue; 3) absence of lipoblast and malignant characteristics; 4) presence of fibrous elements with numerous nerve bundles and vessels; and 5) hypertrophy of subjacent bone. Although these tumors are benign, all three recurred after surgical excision. Extensive specimen sampling is advisable to exclude infiltrating lipoma, diffuse angiomatosis, infiltrating angiolipoma, and well-differentiated liposarcoma. Relationship with lipoblastomatosis and histogenesis of infiltrating congenital lipomatosis of the face are discussed.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
3/5. Congenital infiltrating lipomatosis of the face: clinicopathologic evaluation and treatment.Congenital lipomatosis of the face is characterized by collections of nonencapsulated, mature lipocytes which infiltrate local tissues and tend to recur after surgery. These lesions represent a distinct clinicopathologic entity that has not been previously reported in this location in children. Three children with congenital lipomatosis of the face were treated at the Institute of Reconstructive Plastic Surgery over a 2- to 14-year follow-up period. In each instance, pathologic evaluation by light and electron microscopy revealed similar lesions sharing the following morphologic criteria: (1) nonencapsulated tumors containing mature fat cells, (2) infiltration of adjacent muscle and soft tissue, (3) absence of malignant characteristics, (4) absence of lipoblasts, (5) presence of fibrous elements in conjunction with increased numbers of nerve bundles and vessels, and (6) hypertrophy of subjacent bone. All three lesions recurred after numerous excisions, some of which were extensive. All were benign by histologic examination and remained so for as long as 14 years. Surgical treatment improved the aesthetic appearance of each child despite evidence of tumor persistence. Although these tumors are benign, we recommend an early aggressive surgical approach to control the infiltrative nature of their growth and to improve facial appearance.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
4/5. Pelvic lipomatosis.Although usually in the domain of the urologist, pelvic lipomatosis sometimes first may present to the general surgeon. Often called perivesical lipomatosis, this process of unknown etiology has been defined as a nonmalignant overgrowth of normal fatty tissue limited primarily to the perirectal and perivesical spaces in the pelvis. Typically it occurs in middle-aged, nonobese, men presenting with dysuria and sometimes with suprapubic fullness. High position of the prostate may be noted on rectal examination. urinary tract roentgenograms show a high, gourd-shaped bladder with the surrounding radiolucency of fatty tissues. Elongation of the urethra usually makes cystoscopy difficult. sigmoidoscopy and barium enema may reveal extrinsic pressure on the rectum. Pelvic venography rarely shows external venous compression; arteriography does not suggest neoplastic vessels. Fat metabolism studies are of little value. The absence of adequate cleavage planes renders direct surgical management difficult. The frequently progressive lower ureteral obstruction eventually may require urinary diversion. Four biopsy-proved cases from the Eastern virginia Medical School hospitals are reported, and the 57 previous cases from the literature are reviewed.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
5/5. Radiologic case study. Macrodystrophia lipomatosa.Macrodystrophia lipomatosa is a rare form of gigantism involving an extremity consisting of predominately fibroadipose tissue. Radiographically, it appears as hypertrophy of soft tissues and bone. CT and MR scanning delineate the tissues involved and are virtually diagnostic, demonstrating the predominantly adipose component as well as the overgrowth of the bones, nerves, and vessels also involved.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
