Enchondroma is a type of benign bone tumor belonging to the group of cartilage tumors. [1] [2] There may be no symptoms, [3] or it may present typically in the short tubular bones of the hands with a swelling, pain or pathological fracture. [4] Diagnosis is by X-ray, CT scan and sometimes MRI. [4] Most occur as a less than three centimetre size ...
A glomus tumor (also known as a "solitary glomus tumor" [1]) is a rare neoplasm arising from the glomus body and mainly found under the nail, on the fingertip or in the foot. [2]: 670 They account for less than 2% of all soft tissue tumors. [3] The majority of glomus tumors are benign, but they can also show malignant features. [4]
Bizarre parosteal osteochondromatous proliferation (BPOP), also known as Nora's lesion, [4] is a type of non-cancerous bone tumor belonging to the group of cartilage tumors. [1] [2] [5] It is generally seen in the tubular bones of the hands and feet, [6] where it presents with a rapidly enlarging painless lump in a finger or toe.
Fibroma of tendon sheath is a benign tumor that presents as a small subcutaneous nodule that slowly increases in size. [1] This is a notably uncommon condition. According to case report literature, the tumors often have a multinodular growth pattern, with individual nodules being composed of bland, slender, spindle-shaped cells (myofibroblasts) in a dense, fibrous matrix.” [2] A common ...
Infantile digital fibromatosis (IDF), also termed inclusion body fibromatosis or Reye's tumor, usually occurs as a single, small, asymptomatic, nodule in the dermis on a finger or toe [1] of infants and young children. [2] IMF is a rare disorder with approximately 200 cases reported in the medical literature as of 2021. [3]
Koenen's tumor (KT), also commonly termed periungual angiofibroma, [1]: 668 is a subtype of the angiofibromas. [3] Angiofibromas are benign papule, nodule, and/or tumor lesions that are separated into various subtypes based primarily on the characteristic locations of their lesions.
Glomangiosarcomas display many of the same antigens as their benign counterparts on immunohistochemical labeling; these antigens include vimentin, smooth muscle actin, and muscle-specific actin. [10] On the other hand, benign tumors stain more highly for actin and myosin, and malignant tumors stain more intensely for vimentin. [11]
A benign tumor is a mass of cells that does not invade neighboring tissue or metastasize (spread throughout the body). Compared to malignant (cancerous) tumors, benign tumors generally have a slower growth rate. Benign tumors have relatively well differentiated cells.
