Fibro-adipose vascular anomaly, also known as FAVA, is a type of vascular anomaly that is both rare and painful.FAVA is characterized by tough fibrofatty tissue taking over portions of muscle, most often contained within a single limb.
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 are typically the size of a grain ...
Osteofibrous dysplasia is a rare, benign non-neoplastic condition with no known cause. It is considered a fibrovascular defect. Campanacci described this condition in two leg bones, the tibia and fibula, [1] and coined the term. This condition should be differentiated from nonossifying fibroma and fibrous dysplasia of bone.
Pannus is an abnormal layer of fibrovascular tissue or granulation tissue. Common sites for pannus formation include over the cornea, over a joint surface (as seen in rheumatoid arthritis), or on a prosthetic heart valve. [1] Pannus may grow in a tumor-like fashion, as in joints where it may erode articular cartilage and bone.
The inflammatory fibroid polyp is a benign lesion whose cause is unknown; [13] some reports attribute its genesis to myofibroblasts, [16] while others propose vascular or perivascular tissue. [17] It is widely acknowledged that this is a reactive process to chemical, physical, or microbiological stimuli rather than a neoplasm . [ 18 ]
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]
Pilomatricoma is a benign skin tumor derived from the hair matrix. [ 2 ] [ 3 ] These neoplasms are relatively uncommon and typically occur on the scalp, face, and upper extremities. Clinically, pilomatricomas present as a subcutaneous nodule or cyst with unremarkable overlying epidermis that can range in size from 0.5 to 3.0 cm, but the largest ...
Nodular fasciitis occurs in all age groups but most often affects those between 20–40 years old. Males and females are equally affected. NF tumors, which may be tender or painful, typically present as rapidly growing solitary lesions that reach their final size (usually 2–3 cm) within a few weeks. [10]
