Osteolytic lesion at the bottom of the radius, diagnosed by a darker section that indicates a loss of bone density. An osteolytic lesion (from the Greek words for "bone" (ὀστέον), and "to unbind" (λύειν)) is a softened section of a patient's bone formed as a symptom of specific diseases, including breast cancer and multiple myeloma.
On X-ray, giant-cell tumors (GCTs) are lytic/lucent lesions that have an epiphyseal location and grow to the articular surface of the involved bone. [8] Radiologically the tumors may show characteristic 'soap bubble' appearance. [9] They are distinguishable from other bony tumors in that GCTs usually have a nonsclerotic and sharply defined border.
Ischaemic fasciitis, previously termed atypical decubital fibroplasia or decubital ischemic fasciitis, was thought to be a non-neoplastic lesion and to occur only in the deep subcutaneous tissue at pressure points or bone prominences but more recently has been found to be a benign neoplasm that can occur in a wider range of tissue sites. [5] [6]
If a lesion is caused by a tumor, it can be classified as malignant or benign after analysis of a biopsy. A benign lesion that is evolving into a malignant lesion is called "premalignant". [1] Cancerous lesions are sometimes classified by their growth kinetics, such as the Lodwick classification, which characterizes classes of bone lesions. [3]
Precancerous conditions of the skin or oral cavity can appear as visible lesions without associated pain or discomfort, [7] while precancerous conditions of the hematological system are typically asymptomatic, and in the case of monoclonal gammopathy of unknown significance, it may only rarely cause numbness and tingling in the hands and feet ...

Benign tumors of bone can be similar macroscopically and require a combination of a clinical history with cytogenetic, molecular, and radiologic tests for diagnosis. [23] Three common forms of benign bone tumors with are giant cell tumor of bone, osteochondroma, and enchondroma; other forms of benign bone tumors exist but may be less prevalent.
President Joe Biden had a skin lesion removed that tested positive for basal cell carcinoma.
