Intradural lipoma

A case of an intradural lipoma in the region of the thoraco-lumbar junction in a 24 year old female is reported.     

Parapharyngeal lipoma

A rare case of parapharyngeal lipoma in an elderly male is presented. A brief review of literature is made. Unlike many other previously reported cases, this tumour was a pure lipoma rather than a fibrolipoma.     

A pleomorphic lipoma of the palm--comparison to spindle cell lipoma

A pleomorphic lipoma usually occurs in the neck, the shoulder, and/or on the backs of men over the age of 50. This tumor displays a mixture of fat cells, pleomorphic cells, floret cells, and bundles of mature collagen fiber. Herein we report on a pleomorphic lipoma that occurred on the palm of a 56-year-old woman. An immunohistochemical study, performed to compare the characteristics of a pleomorphic lipoma with those of a spindle cell lipoma, has suggested that the pleomorphic and floret cells of a pleomorphic lipoma are similar to the spindle cells of a spindle cell lipoma and not to fat cells. Our result seems to indicate that these two tumors are on the same spectrum and only the quantity of the pleomorphism keeps them distinct.     

Recurrent laryngeal lipoma

A rare case of laryngeal lipoma is reported with review of literature. We describe our technique of intra laryngeal excision of this tumour by microlaryngeal dissection.     

Retropharyngeal lipoma.

Lipomata in retropharyngeal region are extremely rare. Accurate preoperative diagnosis is very important to assess invasion of muscles and to prevent local recurrence. A case of retropharyngeal lipoma is being discussed along with review of its clinical, radiological and surgical aspects. The role of CT scan in its definitive diagnosis is also discussed.     

Recurrent laryngeal lipoma

A rare case of laryngeal lipoma is reported with review of literature. We describe our technique of intra laryngeal excision of this tumour by microlaryngeal dissection.     

Parapharyngeal space lipoma

I ipomas of the Para-pharyngeal space are rare lesions Very few cases of such tumors have be en reported in the literature Definitive diagnosis and decision regarding the surgical approach Here difficult in the pre CT scan era This was further compounded by the complex anatomy of the Para pharyngeal space A case of Para pharyngeal lipoma is being presented because of its ratity and characteristic radiological features After confirmation of the diagnosis the tumor was excised via a transcertical approach     

Spindle cell lipoma.

Spindle cell lipoma is a specific type of lipoma that is easily mistaken for a liposarcoma. An analysis of 114 cases of this tumor from the files of the Armed Forces Institute of Pathology reveals that is occurs chiefly in male patients between 45 and 70 years of age and affects the regions of the shoulder and posterior neck almost exclusively. Microscopically, it consists of an intricate mixture of lipocytes and uniform spindle cells within a matrix of mucinous material traversed by a varying number of birefringent collagen fibers. Ultrastructural studies in one case support the fibroblastic nature of the spindle cells. Followup information obtained in 63 patients with this lesion revealed a uniformly favorable clinical course, indicating that local excision is the treatment of choice, and that there is no need or reason for radical surgical procedures.     

Gastrointestinal lipoma and malignancies

Twenty gastrointestinal lipomata in 18 patients are reviewed: 15 located in the colon, 3 in the distal ileum, one in the duodenum, and one in the stomach. They were found most frequently in European-born, elderly women and presented with variable abdominal symptomatology. Four lipomata were removed during endoscopy, the remainder at laparotomy, partial colectomy being performed in 10 cases. All, except 2 subserosal types, were located in the submucosa, and their average size was 2.7 cm diameter. Microscopically, none showed true encapsulation, and all were composed of mature fat cells without cellular atypia. In spite of nonspecific changes at endoscopy, one-half of the cases showed, on microscopic examination, atrophy of the overlying glands and a prominent eosinophilic and/or lymphoplasmocytic infiltration of the lamina propria. Two large subserosal lipomata were associated with Crohn's disease. In addition, in 39% of cases, malignant tumours, either single or double, were present in the gastrointestinal tract or elsewhere. Gastrointestinal "lipomata" are located in the sites of normal fatty infiltration in the elderly; these growths could be a local aging or reactive process of the intestinal wall rather than true neoplasms without any potential malignancy. However, coexistent malignancies should be carefully searched for in elderly patients with colonic lipoma.     

Symptomatic lipoma of the duodenum

A case of duodenal lipoma causing massive hemorrhage is described. Literature on the subject is reviewed.     

Unusual case of laryngeal lipoma

Lipomas are benign tumors, composed of fat cells of the adult type. While lipomas on the trunk and limbs are common, they are rare in the upper aerodigestive tract. Here we report a case of laryngeal lipoma presented with a complaint of change of voice.     

Large ulcerated cecal lipoma mimicking malignancy

Colonic lipomas are relatively uncommon tumors of mesenchymal origin, composed of well-differentiated adipose tissue supported by fibrous tissue, that usually occur in cecum and ascending colon. Colonic lipomas rarely cause symptoms and are usually detected incidentally. However, if the lesion is large, it may produce symptoms, such as abdominal pain, rectal bleeding, obstruction, intussusception, and even weight loss. Large colonic lipomas can be mistaken for malignancy, which may result in extensive surgical operations. We report a large broad-based ulcerated cecal lipoma in a 68-year-old woman, who presented with abdominal pain and weight loss. The ulcerated lesion was highly suspicious for malignancy radiologically and endoscopically. The patient underwent laparoscopic right-hemicolectomy, and the lesion was diagnosed as a cecal submucosal lipoma. The surgical approach remains the treatment of choice for large and complicated cases.     

Bilateral lipoma arborescens of the subdeltoid bursa

Lipoma arborescens is a rare cause of chronic monoarticular arthritis. It is most commonly seen in the knees, but only a few cases involving other joints, especially the subdeltoid bursa, have been described. To our knowledge, this is the first reported case of lipoma arborescens involving bilateral subdeltoid bursae. Although it is associated with joint effusion, synovial cysts and erosions, the presence of reactive bone formation has not been reported. Magnetic resonance imaging is a very effective method for the diagnosis of this rare condition because of its ability to do tissue characterization.
