Multiple Brownish Patches on the Trunk in a Patient With Neck Masses.

Multiple brownish patches and plaques in a patient with lung adenocarcinoma indicate cutaneous metastases associated with systemic lymphoid and inflammatory changes.

• Why it matters: This highlights the importance of recognizing skin manifestations as potential signs of metastatic disease, which can influence prognosis and management strategies.
• What they did: The approach involved clinical examination, imaging (CT showing splenomegaly and lymphadenopathy), and laboratory tests revealing elevated inflammatory markers and immunoglobulins, suggesting systemic involvement.
• The result: The findings support a diagnosis of cutaneous metastases from lung adenocarcinoma with systemic lymphoid activation, prompting further oncologic evaluation and tailored treatment planning.
