Surgical treatment of a rare case of tracheal inflammatory pseudotumor in pediatric age
No full textTracheal inflammatory pseudotumor (IPT) is a rare solid lesion with an unpredictable biological course. Treatment can vary and surgical resection may sometimes be necessary, even in pediatric age. We report the case of a 12-year-old male patient who presented to our institution with sudden dyspnoea after some months of wheezing and cough, wrongly considered and treated as asthma. Neck-chest CTscan and fiberbronchoscopy showed an intraluminal tracheal mass, originating from the left antero-lateral wall at the level of the 5th cartilagineous tracheal ring, involving three rings, that was removed by rigid bronchoscopy. Histopathology revealed a tracheal IPT. Due to rapid tendency to recurrence of the lesion, two more endoscopic recanalizations were performed, but a new recurrence appeared, with CT evidence of transmural involvement of the tracheal wall. Resection of the three involved tracheal rings and termino-terminal tracheal anastomosis were successfully performed through cervicotomy and sternal split. CT-scan and fiberbronchoscopy at 17 months from surgery show a stable tracheal lumen without signs of recurrence. A tracheal IPT should be suspected in any pediatric patients with tracheal mass and asthmatic symptoms. After radical removal prognosis is generally excellent and recurrences after tracheal resection are rare
Surgical treatment of a rare case of epithelioid hemangioendothelioma of the azygos vein
No full textEpithelioid hemangioendothelioma (EHE) of soft tissues is a rare low-grade vascular tumour, with variable malignancy. Mediastinal localization is exceptional. We report the first case of a radically resected EHE of the azygos vein (AV). A 47-year old man presented to our institution with an asymptomatic incidental neck–chest computerized tomography (CT) evidence of a 3 cm mediastinal mass, resembling a station 4R lymphadenopathy, with rather distinct margins, strictly adjacent to the AV. 18F-fluorodeoxyglucose positron emission tomography (FDG-PET)/CT revealed a SUV max of 2.3. Fiberbronchoscopy with EBUS-trans-tracheal needle aspiration of station 4R yielded nondiagnostic cytology result. A right lateral thoracotomy revealed an ovoidal mediastinal mass originating from the AV, unresectable from it but showing cleavage from the superior vena cava. The mass with the involved AV was resected en bloc by vascular stapler. Histopathology revealed a venous EHE arising from the AV. For the low mitotic rate and small tumour size, no adjuvant therapy was administered. Total body CT scan at one year from surgery shows neither local recurrence, nor distant metastases. EHE should be considered in the differential diagnosis of mediastinal masses in adult patients. After radical removal prognosis is generally favourable, but strict follow-up must be performed because aggressive forms have been described
