Biopsy of a suspicious skin lesion is necessary. The correct way is to do a full thickness biopsy with 1-2 mm of normal margin.

Depth is important to include dermis and part of subcutaneous tissue for assessing the architecture of the lesion and also for measurement of tumor thickness.

Secondary chest wall tumors from other sites are most common.

Chondrosarcoma is the most common malignant chest wall tumor. It accounts for 20% of all chest wall tumors. 

Radiology shows a poorly defined tumor mass that is destroying cortical bone.

Primary osteosarcomas in the chest account for 10% to 15% of malignant
tumors.  tumor grows rapidly, and radiographic characteristics include a sunburst pattern on CXR.

Ewing sarcoma commonly arises in bones of the pelvis, humerus, or femur of young
men. It is the third most common malignant chest wall tumor
(5% to 10%).
 Radiographic characteristics include an onion peel appearance with periosteal elevation and bony remodeling.

Edema of the mylohyoid muscle causes the tongue to displaced upwards and backwards causing dysphagia and airway obstruction.

Treatment is broad spectrum antibiotic with anaerobic cover

Surgical incision, if required is curved submental to drain both submandibular triangles and mylohyoid muscle.
