Aims. Chondroid lipoma (CL) is a benign tumor that mimics a variety of soft tissue tumors and is characterized by translocation t(11;16). Here, we analyze CL and its histological mimics. Methods. CL (n = 4) was compared to a variety of histological mimics (n = 83) for morphological aspects and immunohistochemical features including cyclinD1(CCND1). Using FISH analysis, CCND1 and FUS were invest...

Lipomatous hypertrophy of the heart is a benign rare abnormality characterized by large fatty tissue deposits in the interatrial septum. An increased incidence of atrial arrhythmias is described in these patients, significant blood flow obstruction however is not the rule. We report a case of lipomatous hypertrophy of the interatrial septum, detected by transeosophageal echocardiography (TEE). ...

Lipomatous hypertrophy of the interatrial septum is a benign cardiac mass that should be considered as part of the differential diagnosis for any atrial cardiac tumour. In the reported case, this lesion was initially suspected to be malignant and the patient was thus referred directly to cardiac surgeons for surgical removal. Unnecessary surgical intervention was swiftly averted because the car...

Lipomatous hemangiopericytoma is a rare variant of hemangiopericytoma. Only a few cases of LHPC have been reported to date, with only two cases of this entity having been reported in the head and neck area, and none intracranially. We present the clinical, radiological, and histological features of the first reported case of a sellar lipomatous hemangiopericytoma, and review the literature. Mat...

Introduction: Lipomas are among the most common tumors of the human body. However, they are uncommon in the oral cavity and are observed as slow growing, painless, and asymptomatic yellowish submucosal masses. Surgical excision is the treatment of choice and recurrence is not expected.    Case Report: The case of a 30-year-old woman with a huge lipoma on the tip of her tongue since 3 years, is ...

Mature fat tissue can be found in both benign lesions and neoplasms of the thyroid gland. The pathophysiology of adipose tissue infiltration in the thyroid gland is not clear. Three cases of diffuse lipomatosis and two cases of thyroid papillary microcarcinoma containing mature fat in their stroma were diagnosed between 2002 and 2009 years. These five cases are presented in this report with a r...

Lipomatous tumors range from benign lipomas to high-grade liposarcomas. Liposarcomas are classified into five histologic subtypes: well-differentiated, dedifferentiated, myxoid, round cell, and pleomorphic, which differ in outcomes and patterns of recurrence. Surgical resection is the mainstay of curative treatment; however, large, high grade liposarcomas may benefit from multimodality treatmen...

ISSN 0001-5555 Sir, Benign symmetric lipomatosis is a rare form of multiple, symmetrical fat distribution. The disorder was first described by Brodie in 1846. It was subsequently characterized by Madelung in 1888 and Launois & Bensaude in 1898 (for review see ref 1). Histologically, cells in th...
