Well circumscribed mass

Her only significant medical history was a routine cesarean section 4 years earlier. Physical examination findings revealed a firm, mobile, nontender, midline abdominal mass. A computed tomographic (CT) scan was performed, which showed a well-circumscribed, 10-cm mass . The patient was scheduled for elective exploratory laparotomy and resection Differential Diagnosis for a solitary, well-circumscribed mass A mass suspicious of breast cancer is a 'space-occupying' lesion seen on at least two mammogram projections. Furthermore, cancerous tumors also tend to be more dense in the middle than at the edges The mammographic mass corresponds to a well-defined sonographic mass that is predominantly isoechoic to fat with a few anechoic oval lucencies within it. This mass was biopsied and found to be a complex benign cyst

A well circumscribed mass lesion with no microcalcifications or architectural distortions would be more in favour of a benign lesion. You should follow up with your breast specialist or doctor about the possible diagnosis and further plan of management. Let us know if you need any other information and post us about how you are doing In the mammography, this composition accounts for the well-circumscribed, round or oval mass, containing fibroglandular tissue and radiotransparent fat, in certain cases associated with a peripheral pseudocapsule, histologically corresponding to the compression of the adjacent normal tissue Lymphangioma appears as a well-circumscribed unicystic or multicystic, homogeneous, or heterogeneous mass.4,32 The lesion may show an isointense or hyperintense signal on Tl-weighted images and an isointense or hypointense signal on T2-weighted images with respect to the vitreous (Table 10.4) Grossly FNHs are well-circumscribed but non-encapsulated and show a central fibrous scar on cut section. They are characterized histologically by hepatic parenchyma arranged in incomplete nodules separated by fibrous tissue which contains abnormal thick-walled vessels, bile ductular proliferation and chronic inflammation (Figure 4). Figure If the margin of the suspected mass seems well-circumscribed in both it's inner and outer edges and is thin and even, this tends to be a sign of a benign mass. The lesion is 'encapsulated' by the compressed adjacent breast tissue and the mass itself is 'pushing against' this tissue, rather than infiltrating and invading it

  1. The most common benign renal mass is called an oncocytoma. Oncocytomas have a typical appearance when large, but when small look similar to malignancy. Another common benign renal mass, more common in fertile women, is called an Angiomyolipoma
  2. The palpable lump corresponds to a well-defined, oval, solid mass of heterogeneous echogenicity. The peripheral portion of this mass is isoechoic to fat (arrows), and the central portion is hyperechoic (arrowheads). This mass corresponds to the lesion identified in Fig. 5.3

Pathological examination revealed that the mass comprised an irregular combination of squamous epithelial and spindle cells, with a mature adipose tissue. Family Medicine 21 years experience Border around nodule: 'circumscribed' defines how sharp the border is around the nodule which is suggestive of benign vs cancerous nodule. If nodule is well-circumscribed, it can be benign or cancerous, but more likely benign. If a nodule is poorly circumscribed, it's more likely to be cancerous Low-grade lesions can present as a well-circumscribed parotid mass, mimicking benign entities, while high-grade lesions can have ill-defined or infiltrative margins (Figure 7). Evaluation for malignant nodes or perineural spread along CN VII is important for accurate staging (Figure 8)

Fibroadenomas typically present as well-circumscribed, rubbery, non-tender, firm masses that slowly grow to a size of 2 to 3 cm.10 Most remain static in size or resolve spontaneously. Clinical. Abstract Most well-circumscribed breast masses are benign lesions such as cysts, fibroadenomas, and intramammary lymph nodes. Nevertheless, 10%-20% of breast malignancies are well-circumscribed masses, and these malignancies include papillary, mucinous, medullary, and metaplastic carcinomas, as well as malignant phyllodes tumors On mammography PASH typically presents as a non-calcified oval mass or as a developing focal asymmetry (Figure 4e). 37 On ultrasound it most commonly presents as a well-circumscribed oval hypoechoic mass. 36,37 Histologically PASH is characterized by slit-like spaces in the stroma lined by spindle-shaped myofibroblasts

A mass must be managed on the basis of its worst features. The histologic findings from excisional biopsy disclosed an invasive ductal carcinoma, with an associated ductal carcinoma in situ. The recommended BI-RADS description is a hypoechoic mass with angular posterior margins, parallel orientation, and no posterior acoustic features: BI-RADS 4B A hypoechoic mass may be a tumor or abnormal growth. It may be benign or malignant. A benign tumor may grow but it will not spread (metastasize) to other organs. A malignant (cancerous) tumor can.. usually seen as a well-circumscribed mass inferior to the conus flow voids are typically seen along the surface of and within the tumor nodule hemorrhage is common, leading to a cap sign on T2 weighted images the characteristic salt-and-pepper appearance of neck and skull base paragangliomas may be see Dr. Mila McManus answered 21 years experience Family Medicine Border around nodule: 'circumscribed' defines how sharp the border is around the nodule which is suggestive of benign vs cancerous nodule. If nodule is well-circumscribed,.. Renal cell carcinoma (RCC) is unusual among cancers in that it often grows as a spherical, well-circumscribed mass. Increasing tumour size influences the pathological pT stage category within pT1 and pT2, with cutoffs of 40, 70 and 100 mm; however, with increasing size also comes a sharp increase in

A hypoechocoic mass in the liver may represent a growth of cancer cells. In the liver, a hypoechoic mass may represent a growth of cancer cells which have traveled from an original tumor elsewhere in the body. This kind of malignant mass, which originates elsewhere, is known as a metastasis, plural metastases Mammogram: Large subareolar well circumscribed mass.

An 18-year-old woman presents with a non-tender mass in the left breast. Breast ultrasound shows a 4.0 cm hypoechoic, oval, circumscribed mass at 4 o'clock. The mass was first noted five years prior and is stable in size. Gross examination of the excised mass reveals a well-circumscribed lesion with a tan-yellow, vaguely lobulated cut surface The specimens consisted of a right upper lobe wedge resection and a right lower lobectomy. The upper lobe wedge revealed a 0.5 cm, firm, tan-brown, stellate nodule. The lower lobectomy showed a 2.7cm, gray tan, firm, well-circumscribed mass, puckering the pleura, and a slightly emphysematous, background lung parenchyma. MICROSCOPIC DESCRIPTIO Bone lesions are lumps or masses of abnormal tissue produced when cells within the bone start to divide uncontrollably. They can stem from an injury or infection, and they may result in bone tumors With the awareness about breast cancer, most women are now cautious about any breast lump in the event that it is a malignant tumor (cancer). However, cancer is not the only cause of an abnormal breast mass and understanding the different types of breast lumps and the character of these masses may help to ease unnecessary concern

A lung (pulmonary) nodule is an abnormal growth that forms in a lung. You may have one nodule on the lung or several nodules. Nodules may develop in one lung or both. Most lung nodules are benign (not cancerous). Rarely, pulmonary nodules are a sign of lung cancer. Lung nodules show up on imaging scans like X-rays or CT scans The most common qualitative ultrasound finding from patients in Group 1 was a well-circumscribed, lobulated echogenic mass, which was observed in 17 (94.4%) patients (Figures 2a, 3a and 4a). The reference ultrasound scans are presented as Figures 2 b, 3 b and 4 b Mass formation occurs due to the excessive, abnormal growth of tissues due to anomalous cell division. Mediastinal mass may be cancerous or benign in nature, which is formed in the chest wall present between the two lungs. Due to the site is termed as mediastinum, so the name of the mass is medically termed as mediastinal mass Here a patient with a mineralized mass in the soft tissues.
