RESUMEN
We present the case of a 22-year-old man who presented with cough, haemoptysis and fever of 3 days' duration. A teratoma had been diagnosed 2 years previously. Physical examination was unremarkable but laboratory tests showed anaemia, neutrophilic leucocytosis and an increase in C-reactive protein. Chest CT revealed a teratoma of the anterior mediastinum with post-obstructive pneumonitis suggestive of tumour rupture. Antibiotic treatment resulted in a good clinical outcome. The patient was submitted to a left upper lobectomy and pathological examination revealed a mature teratoma. Teratomas are germ cell tumours that are usually asymptomatic and their rupture is a rare event. LEARNING POINTS: Mature teratomas are usually asymptomatic.Teratoma bronchial rupture is rare.The most frequent location for mature teratomas is the anterior mediastinum.
RESUMEN
Behçet syndrome (BS) is a variable vessel vasculitis that has pleiotropic manifestations. A 43-year-old male with a previous diagnosis of Crohn's disease (CD) presented with deep venous thrombosis and bilateral superficial femoral artery aneurysms. A diagnosis of BS was made, and the patient was treated aggressively with immunosuppressive therapy and bilateral bypass surgery, attaining a favourable outcome. CD has many features that overlap with BS, and it may be challenging to distinguish between these two conditions, as our case illustrates. Nonetheless, the combination of venous thrombosis and arterial aneurysms should point the clinician towards a diagnosis of BS. LEARNING POINTS: Behçet syndrome is a variable vessel vasculitis of unknown aetiology that has pleiotropic manifestations.Crohn's disease has many overlapping features with Behçet syndrome, namely gastrointestinal, cutaneous, articular, ocular and cardiac manifestations.The combination of venous thrombosis and arterial aneurysms should point the clinician towards a diagnosis of Behçet syndrome.
