Leukocytes and macrophages, obtained from fibroma-immune rabbits and added to immune serum-fibroma virus mixtures, significantly increased the neutralization of fibroma virus as compared with immune serum alone. Immune cell suspensions from peritoneal exudates, regional lymph nodes, buffy coats, spleen, and liver were all effective in inhibiting fibroma virus. Approximately 2000 to 4000 immune ...

Cardiac fibromas are rare benign tumors usually seen in the pediatric population. Generally, long-term survival after surgical resection is favorable, and recurrence of fibroma has been hardly reported. Herein, we report a case of a 34-year-old woman who presented with ventricular tachycardia 21 years after resection of a cardiac fibroma and was found to have a recurrent giant cardiac fibroma. ...

Introduction Gingival growths are one of the most frequently encountered lesions in the oral cavity. Most of these lesions, such as irritational fibroma, pyogenic granuloma, peripheral ossifying fibroma and peripheral giant cell granuloma, are innocuous and rarely present with aggressive features. In majority of cases, these lesions are the result of trauma or chronic irritation. One of the inf...

Chondromyxoid fibroma is a rare benign bone tumor. The etiology of chondromyxoid fibroma is still unknown. We report a case of a 26-year-old male who suffered from chronic cough for a year. His chest radiograph showed a lobulated tumor over the left seventh rib. The computed tomography (CT) examinat ion further revealed an osteolytic tumor arising from the left seventh rib with calcified matrix...

Background: Nevus lipomatosus cutaneous superficialis (NLCS) of Hoffmann–Zurhelle is a benign idiopathic hamartoma. There are two types NLCS, multiple and solitary. They found in the abdomen, lower back, buttocks, hips, upper posterior thighs, pelvis. The diagnosis can be evaluated with typical histopathological mature fat cells dermis, 10%–50% dermis.
 Case Report: We reported case NLCS c...

juvenile ossifying fibroma (jof) is a rare, benign, locally aggressive entity of the extragnathic craniofacial bones with a high tendency towards recurrence. two distinctive microscopic patterns of juvenile ossifying fibroma have been described: a trabecular juvenile ossifying fibroma (trjof) and a psammomatoid juvenile ossifying fibroma (pjof). psammomatoid variant is predominantly a craniofac...

detected in several cases [4]. In our case, immunohis-tochemical staining for vimentin was not performed. Positivity for vimentin implies that the tumor cells are of fibroblastic lineage. However, we were able to determine that with the satellite to spindle shape of cells. Histopathologically, the tumors appear well-mar-ginated under low-power microscopic examination. The tumor cells are relati...

Central cementifying fibroma is a rare non odontogenic tumor coming in the group of fibro osseous lesion, arising from periodontal ligament and is usually seen in tooth bearing area. It can affect both the mandible and the maxilla, particularly the mandible. This bone tumour consists of highly cellular, fibrous tissue that contains varying amounts of calcified tissue resembling bone, cementum o...

Nuchal-type fibroma, initially described in 1988 by Enzinger and Weiss, is a rare clinical entity associated with distinct subcutaneous and dermal fibrous tissue proliferation. The etiology of nuchal-type fibroma largely remains to be elucidated. Typical characteristics of this entity include hypocellular, haphazardly arranged collagen with entrapped adipose tissue, paucity of elastin and entra...

Twelve neonate calves were repeatedly challenged with bovine papilloma virus. All calves were initially susceptible to bovine papilloma virus and complete resistance to challenge occurred after the onset of fibroma regression. Fibroma regression was not correlated with serum antibody titers to bovine papilloma virus as measured by an immunodiffusion assay. Fibroma regression occurred prior to t...
