Dermatofibrosarcoma protuberans (DFSP) [2] is a rare locally aggressive malignant cutaneous soft-tissue sarcoma. DFSP develops in the connective tissue cells in the middle layer of the skin (dermis). [3] Estimates of the overall occurrence of DFSP in the United States are 0.8 to 4.5 cases per million persons per year.
A dermatofibroma, or benign fibrous histiocytomas, is a benign nodule in the skin, typically on the legs, elbows or chest of an adult. [3] It is usually painless. [3] It usually ranges from 0.2cm to 2cm in size but larger examples have been reported. [3] It typically results from mild trauma such as an insect bite. [3]
They can grow in all organs, arising from mesenchyme tissue. The term " fibroblastic " or "fibromatous" is used to describe tumors of the fibrous connective tissue . When the term fibroma is used without modifier, it is usually considered benign , with the term fibrosarcoma reserved for malignant tumors.
A skin tag, or acrochordon (pl.: acrochorda), is a small benign tumor that forms primarily in areas where the skin forms creases (or rubs together), such as the neck, armpit and groin. They may also occur on the face, usually on the eyelids. Though tags up to 13 mm (1 ⁄ 2 inch) long have been seen, [2] they
[1] [2] The blue colour is caused by the pigment being deep in the skin. [4] Diagnosis is by visualisation and dermoscopy. [4] A biopsy is sometimes performed, or the whole lesion surgically removed. [3] The outcome is generally good but there is a small chance of cancerous transformation. [3] Differential diagnosis includes dermatofibroma and ...

In general, a bone marrow biopsy is part of the "work up" for the analysis of these diseases. All specimens are examined microscopically to determine the nature of the malignancy. A number of these diseases can now be classified by cytogenetics (AML, CML) or immunophenotyping (lymphoma, myeloma, CLL) of the malignant cells. [citation needed]
However, a benign tumor is not benign in the usual sense; the name merely specifies that it is not "malignant", i.e. cancerous. While benign tumors usually do not pose a serious health risk, they can be harmful or fatal. [2] Many types of benign tumors have the potential to become cancerous through a process known as tumor progression. For this ...
