Histopathologic study of the rectum in 1,438 consecutive rectal specimens in a single Japanese hospital: I. benign lesions.
Abstract The author investigated histopathology of 1,438 consecutive rectal specimens in the last 10 years of our pathology laboratory in Japan. A computer review of pathologic reports was done. Observations of pathologic slides were performed, when appropriate. The rectal specimens were composed of 1,022 benign lesions and 416 malignant lesions. The 1,022 benign lesions were composed non-specific proctitis (n=460, 45%), adenoma (n=248, 24%), ulcerative colitis (n=98, 10%), hyperplastic polyp (n=54, 5%), carcinoma in adenoma (n=40, 4%), rectal ulcer (n=37, 4%), serrated adenoma (n=24, 2%), hyperplastic nodule (n=21...

Large gastric lipoma presenting with GI bleeding
A 60-year-old man presented with melena, easy fatigability of 2 weeks' duration, and pallor. The results of systemic examination were normal. His hemoglobin was 7.2 g/dL, with normal blood biochemistry. Upper GI endoscopy (UGIE) showed a large smooth submucosal bulge along the lesser curvature of the stomach (). Contrast-enhanced CT (CECT) of the abdomen showed a well-defined encapsulated submucosal fat-containing mass along the lesser curvature of the stomach, with a vessel running through it (). The patient received a transfusion of packed red blood cells and underwent laparotomy. A large (15 × 12 cm) submucosal tumor w...

Lipomas of the cerebellopontine angle and internal auditory canal
ConclusionsWhile rare, lipomas should be included in the differential diagnosis of CPA and IAC lesions. Owing to a generally benign clinical course and high morbidity associated with resection, microsurgery should only be considered in cases of definite tumor enlargement with intractable symptoms from mass effect. Careful radiological evaluation is critical for establishing an accurate diagnosis in order to prevent unnecessary morbidity associated with resection. Level of Evidence2b. (Source: The Laryngoscope)

Cyclin‐dependent kinase inhibitor 2A (p16) distinguishes well‐differentiated liposarcoma from lipoma
Distinction between lipoma and well‐differentiated liposarcoma (WDL) is crucial because of the differences in prognosis and in treatment regimens. Although this is often readily accomplished via routine histopathologic examination, cases occur regularly in which the diagnosis is equivocal. Currently, the gold standard diagnostic test for this differential diagnosis is fluorescence in situ hybridization (FISH) for amplification of the MDM2 and CDK4 genes.1‐2 © 2013 Blackwell Publishing Ltd (Source: Histopathology)

Management of Intraneural Fibro-Lipoma of the Median Nerve and the Role of Pressure-Specified Sensory Device (PSSD) for the Patient's Motor and Sensorial Evaluations.
CONCLUSION: The decompression of intraneural fibro-lipoma of the nerve with limited excision and epineurotomy without sacrificing the main nerve and its branches is the ideal surgical procedure. We recommend the use of PSSD in the investigation of patients with peripheral nerve compression, and chronic unusual volar forearm and wrist swelling. PSSD is an important tool for pre-operative evaluation and diagnosis of intraneural fibro-lipoma. PMID: 23344864 [PubMed - in process] (Source: Turkish Neurosurgery)

The m.3291T>C mt-tRNALeu(UUR) mutation is definitely pathogenic and causes multisystem mitochondrial disease
Abstract: Mitochondrial tRNA point mutations are important causes of human disease, and have been associated with a diverse range of clinical phenotypes. Definitively proving the pathogenicity of any given mt-tRNA mutation requires combined molecular, genetic and functional studies. Subsequent evaluation of the mutation using a pathogenicity scoring system is often very helpful in concluding whether or not the mutation is causing disease. Despite several independent reports linking the m.3291T>C mutation to disease in humans, albeit in association with several different phenotypes, its pathogenicity remains controversial. ...

Tumors of the Foot and Ankle: A Single-institution Experience
Abstract: Tumors of the foot and ankle are rare, and the particular clinicopathologic features, therapeutic approach, and outcomes in this setting are not well established. From January 2000 to December 2010, 72 patients with primary musculoskeletal tumors of the foot and ankle, both benign and malignant, were treated at a single institution. Of the 72 patients, 56% were female. The median age was 52 years. Of the 72 tumors, 62 (86.11%) were located in the foot and 10 were located in the ankle; 63 (87.5%) were soft tissue tumors and 9 (12.5%) were bone tumors. Overall, 56 (78%) were benign tumors and 16 (22%) were maligna...

Nonepithelial skin tumors with multinucleated giant cells
Recognition of the different types of multinucleated giant cells in neoplastic and pseudotumoral lesions of the skin may be helpful in the differential diagnosis of these tumors. In this review, we will analyze the different types of multinucleated giant cells that can be found in nonepithelial cutaneous tumors and, more importantly, the clinicopathological context in which they are found. Touton giant cells are typically present in juvenile xanthogranuloma, necrobiotic xanthogranuloma, and some subtypes of xanthomas. Giant cells with a ground glass appearance are typically present in the solitary reticulohistiocytoma and ...

Dedifferentiated Liposarcoma With Lipoma-Like Well-Differentiated Liposarcoma: Clinicopathological Study of 30 Cases, With Particular Attention to the Comingling Pattern of Well- and Dedifferentiated Components: A Proposal for Regrouping of the Present Subclassification of Well-Differentiated Liposarcoma and Dedifferentiated Liposarcoma
Dedifferentiated liposarcoma (DDL) is defined as nonlipogenic sarcoma, with an abrupt transition from coexisting well-differentiated liposarcoma (WDL). However, intermingled transition in a mosaic pattern between WDL and DDL is not infrequently encountered. Here, the authors review clinicopathological features of 30 cases of DDL associated with lipoma-like WDL. Histological examination revealed 20 tumors that showed an abrupt transition between WDL and DDL. Among these, 13 tumors showed high-grade spindle-cell sarcoma having histological features of unclassified malignant fibrous histiocytoma (MFH)-like sarcoma (high-grade...

Cardiac Lipoma at Unusual Location – Mimicking Atrial Myxoma
We report a 26‐year‐old female presenting with atypical chest pain. Transthoracic echocardiogram showed a mass in relation to interatrial septum suggestive of atrial myxoma, but was confirmed to be cardiac lipoma on magnetic resonance imaging. Owing to the asymptomatic character and the benign nature of the tumor, a decision for conservative management was made. (Source: Echocardiography)

Intramuscular lipoma of the tongue masquerading as angioedema.
We report a case of an infiltrating lipoma of the tongue that masqueraded as angioedema. The patient, a 68-year-old man, presented with tongue swelling that had followed a waxing and waning course over a 6-month period. Physical examination showed a diffusely enlarged tongue with no discrete mass. A laboratory evaluation for angioedema was unremarkable. After the patient's condition did not respond to treatment with antihistamines and oral prednisone, a further workup was initiated. Magnetic resonance imaging of the neck and computed tomography of the oral cavity revealed only diffuse enlargement of the tongue. The patient...

Breast cancer cells that undergo an Epithelial-to-Mesenchymal transition co-opt LPP, a regulator of mesenchymal cell migration and invasion.
Transforming Growth Factor β (TGFβ) promotes breast cancer cell metastasis to multiple sites, including the bone and lungs. TGFβ is a strong inducer of Epithelial-to-Mesenchymal transitions (EMT) and breast cancers that exhibit features of an EMT acquire stem cell-like characteristics, are highly aggressive, are resistant to therapy and are refractory to tumor suppressive processes. While TGFβ itself is non-oncogenic, it is a potent modifier of the malignant phenotype in breast cancer and is capable of enhancing the migration, invasion and metastasis of ErbB2 expressing breast cancer cells.We have ident...

Spinal Cord Tumors: New Views and Future Directions
Spinal cord tumors are uncommon neoplasms that, without treatment, can cause significant neurologic morbidity and mortality. The historic classification of spine tumors is based on the use of myelography with 3 main groups: (1) extramedullary extradural, (2) intradural extramedullary, and (3) intradural intramedullary. This chapter focuses on intramedullary spinal cord tumors (ISCTs), with an emphasis on new diagnostic imaging modalities and treatment options. The common ISCTs include ependymoma, astrocytoma and hemangioblastoma, which together account for over 90% of primary ISCTs. Rare tumors such as gangliglioma, oligod...

Pleomorphic lipoma lacking mature fat component in extensive myxoid stroma :a great diagnostic challenge
Pleomorphic lipoma is a relatively uncommon entity, and is considered as a variant of spindlecell lipoma. Histologically, spindle cell lipoma/pleomorphic lipoma consists of varyingquantity of mature fat, bland spindle cells and ropey collagen. In addition, pleomorphiclipoma is characterized by multinucleate giant cells, which possess the "floret-like" nucleiand marked pleomorphism. So, in contrast to spindle cell lipoma, pleomorphic lipoma ismore easily misdiagnosed as a malignant tumor. Herein, we report a peculiar case ofpleomorphic lipoma occurring in axilla with entirely devoid of mature fat in a 71-year-oldmale. The h...

Benign anal and perianal polypoid neoplasms and tumor-like lesions.
Abstract Mesenchymal anal and perianal tumors are relatively uncommon. The majority are malignant. Benign mesenchymal anal tumors are rare. Some are common stromal neoplasms, but with the rare presentation as anal polyps. Other lesions are rare, but unique to the anal/perianal region. Common keratinous cysts might uncommonly present as anal polyps, while other rare cysts are unique to the anogenital region. A retrospective review study of 493 anal and perianal specimens conducted over seven years showed twenty cases (4.0%) of benign anal polypoid lesions. We excluded the usual fibroepithelial polyps, anal tags, pap...

Cases were stratified into four patterns of staining: 1-diffuse positivity, when 30% of cells were strongly immunoreactive; 2-moderate positivity, when 10–29% of cells were moderate to strongly immunoreactive; 3-focal positivity, with 10% immunoreactive; and 4-negative.

Intraoral surgical approach of large dermoid cysts in floor of mouth
Dermoid cysts are uncommon, benign congenital tumors of ectodermal origin that can occur in any region of the body. Nearly 7% occur in the head and neck region and 1.6% occur on the floor of the mouth. The etiology includes accidental or surgical events in which the epithelium is traumatically implanted within deeper structures. We hereby report a case of a large dermoid cyst on the floor of the mouth of a 13-year-old boy. He was complaining of a bulge on the bottom of his mouth. Although he experienced no painful symptoms, he reported the lump growing over two months and noticed changes in his speech. The lesion was a smo...

Atypical lipoma of the tongue
A 60-year-old Caucasian male patient, presented with an asymptomatic nodule of 2.5 cm, with yellowish coloration and firm consistence, in the right lingual border, with 2 years of evolution. The clinical diagnosis was lipoma and an excisional biopsy was performed. The histopathological examination revealed a proliferation of adipocytes, and in some specific areas, spindle cells with hyperchromatic/peripheric nuclei and some small vesicles in the cytoplasm, interpreted as atypical lipoblasts. Also, there was a capsule lining the lesion and a fragment of normal stratified epithelium. The immunohistochemical analysis revealed...
