Generality The pyogenic granuloma is a benign vascular tumor, which originates from the rapid and uncontrolled proliferation of an epithelial cell of a blood vessel with a cutaneous or situated on a mucosa. The precise causes of pyogenic granuloma are unknown; on the basis of certain observations, however, the doctors believe that, on the appearance of the tumor in question, circumstances or events may affect such as: skin wounds, burns, insect bites, pregnancy, use of the contraceptive pill, l 'taking certain drugs (eg chemotherapeutic drugs, systemic retinoids, etc

What is lymphoma? Lymphoma is a primary neoplasm of lymphoid cells. More precisely, by "lymphoma" we mean a heterogeneous group of malignant tumors that involve the lymph nodes and the lympho-glandular apparatus in general, including also B lymphocytes, T lymphocytes and relative precursors

Lymphocyte tumor Burkitt's lymphoma is named after the surgeon D. Burkitt, who first described its symptoms around the middle of the twentieth century; a decade later, Burkitt's lymphoma was included in the class of malignant neoplasms. Burkitt's lymphoma is considered a B-lymphocyte-derived tumor: it is a rare neoplasm with a high incidence among African children

Definition Non-Hodgkin's lymphomas represent a heterogeneous and complex group of malignant neoplasms affecting the organs and cells of the lymphatic system. However, it is not uncommon for non-Hodgkin's lymphomas to also affect extra-lymphatic areas, considering that the cells of the autoimmune system are located in very many areas of the body

Definition of cutaneous lymphoma Cutaneous lymphoma is inserted among the rare neoplasms of lymphatic tissue, and manifests itself with the abnormal development of T cells (a type of white blood cells) at the level of the skin. Cutaneous lymphoma is defined as a monoclonal proliferation of lymphatic cells that occurs at the skin level : if the skin is the onset locus ( primary cutaneous lymphoma ), it does not mean that the tumor cannot expand into other tissues, indeed, in most in some cases, cutaneous lymphoma evolves into other districts causing substantial damage

Lymphatic system tumor Lymphoma - or Hodgkin's syndrome, also called malignant lymphogranuloma , is a fairly rare neoplasm of the lymphatic system, when compared with non-Hodgkin type tumors; the disease bears the name of the discoverer, Thomas Hodgkin, who described this neoplastic form for the first time around the 1830s

Cutaneous lymphomas Among the cutaneous lymphomas affecting T cells, there are mycosis fungoides and Sèzary's syndrome, two primary neoplasms that occur at the skin level, developing an asymptomatic but incurable disease. In this regard, in most cases, therapies fail to heal patients suffering from mycosis fungoides or Sèzary's syndrome, but the treatments are useful to lighten the symptoms.

Kaposi's syndrome Kaposi's disease (or syndrome) frames a multifocal malignant neoplastic form, not very frequent, which mainly involves the skin, viscera and mucous membranes. Kaposi's bite has a vascular origin and presents with typical eruptions (papules and / or nodules) or macules with a reddish-violet color, often of a haemorrhagic nature

Definition of polyp In pathology, the term "polyp" defines an anomalous tissue spongescence, soft and spongy, which grows along a mucous membrane and protrudes into a body cavity. In the figure we see the example of intestinal polyps, which develop in the mucosa of the colon. Classification Polyps are classified based on several elements: Shape and surface: the polyps can have a regular shape and a smooth surface, or show an evident irregularity, with a rough and knurled surface

Pleural tumor Pleural cancer is a severe and potentially fatal form of cancer that affects the pleura, the double serous membrane that covers and supports the lungs in the thoracic cavity. More precisely, we speak of pleural mesothelioma when the tumor exclusively affects the mesothelium (epithelium that envelops all the large serous cavities such as the pleural cavity)
