RESUMO
Thymomas are rare tumors originating from thymic tissue and rarely metastasize. They can be diagnosed either incidentally or symptomatically when compressing or invading nearby structure. A 36-year-old man presented with significant high-grade fever, chest pain that worsens upon lying down, and dyspnea. A chest X-Ray and computed tomography followed by biopsy confirmed the diagnosis of thymoma. The management included chemotherapy cycles, followed by surgery. Pericardiectomy was performed with en-bloc thymectomy and partial resection of the infiltrating lung. Venous drainage was restored by 8/16 mm inverted bifurcated brachiocephalic-superior vena cava Dacron bypass. The pericardium was reconstructed by a synthetic Dacron patch, and the right diaphragm metastasis was resected. Neoadjuvant chemotherapy was initiated. After 3 months of follow-up, no recurrence was evidenced by computed tomography.
RESUMO
Introduction and importance: Systemic sclerosis (SSc) is divided into three subtypes: limited cutaneous SSc (lcSSc), diffuse cutaneous SSc (dcSSc), and systemic sclerosis sine scleroderma (ssSSc). ssSSc is a rare subtype of SSc that presents with internal organ manifestations but no cutaneous findings. Case presentation: We report the case of a 58-year-old patient with a history of pulmonary hypertension who presented with symptoms of fatigue, inflammatory polyarthritis, and joint swelling. Following a comprehensive clinical examination and laboratory tests, the patient was diagnosed with ssSSc. Clinical discussion: Due to its atypical clinical course, we present this case report, which commenced with idiopathic pulmonary hypertension. Subsequently, after 7 months, the patient presented complaints of polyarthritis with positive antinuclear antibodies. Raynaud's phenomenon was identified 2 months later during the rheumatology clinic examination. Typically, the clinical course encompasses all three features simultaneously, without any gap between them. Conclusion: Diagnosis of ssSSc remains challenging, and it is essential to consider this disease form in all cases involving unexplained fibrotic involvement of the internal organs.
