Abstract
Melanoma can spread to any organ of the body. The most affected sites are the skin and subcutaneous tissue, lymph nodes, lungs, liver, brain, bone, and intestine. Early diagnosis is crucial to prompt treatment. Although the incidence of melanoma is rising, novel treatment options are being developed, enabling a better prognosis. The authors present a rare case of metastatic melanoma affecting the muscle, lymph nodes, and subcutaneous tissue. The patient complained of redness and swelling of the right thigh and inguinal region, red, painful lumps on her chest wall, and pain in the left upper abdominal quadrant. A CT of the thorax, abdomen, and pelvis was performed, and surgical excision of the left thoracic mass led to the diagnosis of metastatic melanoma. However, no primary lesion was found despite extensive investigation. The unusual presentation of muscular metastasis heralds a poor prognosis. This case highlights the difficulty of diagnosing patients with rare presentations of a rather frequent disease.
