Desmoplastic reaction to breast cancer. Desmoplasia refers to growth of dense connective tissue or stroma. [2] This growth is characterized by low cellularity with hyalinized or sclerotic stroma and disorganized blood vessel infiltration. [3] This growth is called a desmoplastic response and occurs as result of injury or neoplasia. [2]

The signs and symptoms of most neoplasms are due to their mass effects caused by the invasion and destruction of tissues by the neoplasms' cells. Signs and symptoms of a cancer causing a paraneoplastic syndrome result from the release of humoral factors such as hormones , cytokines , or immunoglobulins by the syndrome's neoplastic cells and/or ...
Between 26% and 80% of TSC patients have benign tumors of the kidneys called angiomyolipomas, with hematuria being the most frequent presenting symptom. [ 8 ] TSC angiomyolipomas differ from non-TSC angiomyolipomas in age of presentation (31.5 years vs 53.6 years), mean tumor size (8.2 cm vs 4.5 cm), and percentage of cases requiring surgical ...
[citation needed] There are four elements in this tumour: solid, papillary, sclerotic and hemangiomatous. These are present in variable proportions depending on the lesion. These are present in variable proportions depending on the lesion.
Inflammatory demyelinating diseases (IDDs), sometimes called Idiopathic (IIDDs) due to the unknown etiology of some of them, are a heterogenous group of demyelinating diseases - conditions that cause damage to myelin, the protective sheath of nerve fibers - that occur against the background of an acute or chronic inflammatory process.
Eye cancers can be primary (starts within the eye) or metastatic cancer (spread to the eye from another organ). The two most common cancers that spread to the eye from another organ are breast cancer and lung cancer. [2] Other less common sites of origin include the prostate, kidney, thyroid, skin, colon and blood or bone marrow.
