Atypical Lipomatous Tumor in the Submental Region

Journal of Craniofacial Surgery, 2008
A 54-year-old male patient presented to our outpatient clinic complaining of a mass under his chin, which appeared nearly 1 year earlier. Pathologic diagnosis was atypical lipomatous tumor. To the best of our knowledge, this is the first reported case to localize subcutaneously in the head and neck region. Atypical lipomatous tumors/well-differentiated

Advances in Anatomic Pathology, 2010
The so-called "giant fibrovascular polyps" of the esophagus and hypopharynx typically present as sausage-like pedunculated structures that protrude into the lumen and cause obstructive symptoms. Most are cured by local resection but they may recur.

An atypical pleomorphic lipomatous tumor arising on the cheek

Journal of Cutaneous Pathology, 2019
AbstractPathologists and dermatopathologists commonly encounter tumors with adipocyte differentiation. Most are of minimal clinical significance. Those exhibiting atypical spindle cell morphology have been reported but the terminology for such neoplasms is unsettled.

Atypical lipomatous tumors of the face: a controversial issue

European Archives of Oto-Rhino-Laryngology, 2006
We reviewed the topic of atypical lipomatous tumors including definition, diagnosis and management, with special emphasis on head and neck location and to report on the management of a rare case located in the temporalis muscle. Atypical lipomatous tumors/well-differentiated liposarcomas (ALT/WDLS) are rarely reported in the head and neck.

Atypical Spindle Cell/Pleomorphic Lipomatous Tumor

Surgical Pathology Clinics
Atypical spindle cell/pleomorphic lipomatous tumor (ASCPLT) is a rare soft tissue neoplasm, commonly arising in the subcutis (more common than deep soft tissue) of limbs and limb girdles during mid-adulthood. ASCPLT is histologically a lipogenic neoplasm with ill-defined margins composed of a variable amount of spindle to pleomorphic/multinucleated ...

Value of cytological imprints in the diagnosis of atypical lipomatous tumor

Diagnostic Cytopathology, 2004
AbstractThe diagnosis of atypical lipomatous tumor by biopsy, requires careful examination of several slides, in order to look for atypical cells. We suggest that imprints of lipomatous tumors may play a complementary role in such a search, and report a case of a 74‐yr‐old woman with an atypical lipomatous tumor of the left thigh, in which imprints ...

Atypical Lipomatous Tumor/Well-Differentiated Liposarcoma: What Is It?

Surgical Oncology Clinics of North America, 2012
Liposarcoma (LPS) is the most common soft tissue sarcoma, frequently found in the thigh and retroperitoneum. LPS is commonly classified into well-differentiated LPS and dedifferentiated LPS. Histologic subtype, tumor location, and completeness of surgical resection are important prognostic indicators for LPS.

Well-differentiated liposarcoma (atypical lipomatous tumors).

Seminars in diagnostic pathology, 2001
Well-differentiated (WD) liposarcoma accounts for about 40% to 45% of all liposarcomas therefore representing the larger subgroup of adipocytic malignancies. It tends to occur equally in the retroperitoneum or the limbs followed by the paratesticular area and the mediastinum, with a peak incidence between the fifth and the seventh decades.

Atypical lipomatous tumors of the tongue: report of six cases

Virchows Archiv, 2009
The occurrence of liposarcoma in the tongue is rare with only 34 cases published so far. We report six new cases of atypical lipomatous tumor (ALT) of the tongue, and detection of mdm-2 and CDK4 expression by immunohistochemistry and fluorescence in situ hybridization (FISH), respectively, was performed.

Smooth Muscle in Atypical Lipomatous Tumors

The American Journal of Surgical Pathology, 1990
Three cases of atypical lipomatous tumor with areas of smooth muscle are presented. The patients were a 49-year-old man, a 45-year-old woman, and a 63-year-old man; their neoplasms were located in the spermatic cord, the mediastinum, and the retroperitoneum, respectively. The smooth muscle foci were well differentiated in all cases.
