What is solid Pseudopapillary neoplasm?

Solid pseudopapillary tumor (SPT) of the pancreas is a rare neoplasm, usually characterized by a well encapsulated mass, with low malignant potential. It occurs predominantly in young females, in their third decade of life.

What causes solid Pseudopapillary tumor?

Solid-pseudopapillary neoplasm (SPN) of the pancreas also known as Frantz’s tumor is an uncommon tumor that mainly occurs in females in their second to fourth decades of life [1]. It accounts for less than one percent of pancreatic tumors and typically arises from the pancreatic tail [2].

What does Pseudopapillary mean?

Background. Solid pseudopapillary tumor, otherwise known as solid and cystic tumor or Frantz tumor, is an unusual form of pancreatic carcinoma. Its natural history differs from the more common pancreatic adenocarcinoma in that it has a female predilection, is more indolent, and carries a better prognosis.

What is acinar cell carcinoma?

Acinar cell carcinoma, also known as acinic cell carcinoma, is a malignant epithelial neoplasm composed of cells with morphological resemblance to acinar cells and with evidence of exocrine enzyme production by the neoplastic cells.

What is acinar pattern?

From Wikipedia, the free encyclopedia. Acinar adenocarcinoma is a histological subtype of gland-forming cancer that is diagnosed when cuboidal and/or columnar shaped malignant cells in the neoplastic tissue form acini and tubules. It is a common form of cancer occurring in the lung and prostate gland.

Is acinic cell carcinoma hereditary?

The histologic features of both neoplasms were typical of acinic cell carcinoma. While this may represent a coincidental event, the possibility that this familial occurrence is a manifestation of common genetic or environmental risk cannot be excluded.

What are neoplasia, tumors and cancer?

Neoplasia is the abnormal growth and proliferation of abnormal cells or abnormal amounts of cells due to a benign or malignant process. There can be benign tumors, or neoplasms, and malignant ones. Remember that it’s the malignant tumors, or cancer, that can metastasize, which is when cancer spreads around the body.

What is a solid neoplasm?

A solid neoplasm is a particular type of tumor that can appear anywhere on the body. Different from fluid-filled tumors, these types are solid masses and may be benign or malignant.

Are all neoplasms malignant?

A neoplasm can be benign, potentially malignant, or malignant (cancer). Benign tumors include uterine fibroids, osteophytes and melanocytic nevi (skin moles). Potentially-malignant neoplasms include carcinoma in situ. Malignant neoplasms are commonly called cancer.
