D03.5
Melanoma in situ of trunk
Clinical Classification Guidelines
Medical Intelligence & Overview
Melanoma in situ of the trunk is an early form of skin cancer that develops on the main part of the body, excluding the limbs and face. 'In situ' means the cancer cells are confined to the outermost layer of the skin and have not invaded deeper tissues. Accurate diagnosis and treatment are essential to prevent progression to invasive melanoma, which can be life-threatening.
Causes & Symptoms
Clinical Causes: Excessive exposure to ultraviolet (UV) rays from sunlight or tanning beds Having fair skin, light-colored eyes, or red hair, which may increase susceptibility History of sunburns, especially during childhood Genetic predisposition or family history of melanoma or other skin cancers Presence of numerous moles or unusual moles (dysplastic nevi)
Key Symptoms: A new mole or skin growth that looks different from others A changing mole, with alterations in size, shape, or color A flat or slightly raised brown or black patch with irregular borders An unevenly pigmented lesion with varying shades of brown, black, or even pink Itching, tenderness, or bleeding in the affected area (less common)
Diagnostic & Treatment
Diagnosis Path: Diagnosis generally involves a thorough skin examination by a healthcare professional. If suspicious lesions are identified, a biopsy is performed, where a small sample of skin tissue is removed and examined under a microscope to confirm the presence of melanoma cells confined to the epidermis. Additional imaging or tests may be used if invasive melanoma is suspected or to evaluate the extent of the disease.
Treatment Protocols: Treatment options focus on complete removal of the melanoma in situ to prevent progression. Common approaches include:
