Paraneoplastic Scleroderma: A Case Report of Systemic Sclerosis in the Setting of Pulmonary Adenocarcinoma

A 42-year-old female with a past medical history significant for scleroderma and extensive tobacco use presented with a dry cough and pleuritic chest pain. Further workup was significant for leukocytosis, macrocytic anemia, left lower lung mass, bilateral supraclavicular, hilar, and mediastinal lymphadenopathy. After a comprehensive rheumatologic workup was completed, the patient was found to have strongly positive antinuclear antibody (ANA) and negative scleroderma-specific antibodies with fluorescent ANA indicating a nucleolar pattern. We present a case of paraneoplastic scleroderma in the setting of lung adenocarcinoma which emphasizes the bidirectional relationship that exists between malignancy and rheumatic diseases.
