Intra thoracic extra pulmonary hydatidosis: prognosis and outcomes of 8 operated patients.

Hydatid cyst disease is a parasitic disease known from the times of hippocrates, and is still endemic in our country Morocco among others, affecting mainly the liver and lungs, while intra thoracic extra pulmonary location remains a rare entity of the disease. In our department of thoracic surgery, Mohamed VI University Hospital, Oujda, Morocco, we operated 92 patients for thoracic hydatid cyst in the period between January 2016 and December 2021, 8 patients of this group had exclusive extra pulmonary location of the hydatid cyst, epidemiological and clinical data were recorded for the 8 patients (5 men, 3 women). The mean age was 40.3 years, all patients presented mainly with chest pain, dyspnea and cough. The locations of the hydatid cysts were chest wall, pericardium, pleural space and diaphragm. The hydatid cysts were removed via extirpation technique through thoracotomy in all patients. The average duration of hospitalization was 7 days. Postoperative complications consisted of atelectasis in one patient, parietal hematoma in another, and surinfection with pleuro-cutaneous fistula and chronic neurological chest pain in one patient. No deaths were noted in our series.

INTRODUCTION: Glomangiomatosis is a benign tumour proliferation which develops from the glomus cells in the wall of a vessel, and which contains abnormal venous capillaries. Its usual location is dermal at the extremities, mediastinal presentation is exceptional. OBSERVATION: A 63-year-old patient, followed for scoliosis, was admitted for a spontaneous haemothorax. The CT scan found hypervascularized left paravertebral masses. Thoracoscopy with biopsy provided the diagnosis of a glomus tumour. Given that its diffuse nature makes surgical excision difficult and the risk of intraoperative bleeding very high, treatment with interleukin alpha 2 was proposed to the patient. After a 3-year course, we did not observe any evolutionary change in the lesions. CONCLUSION: Glomangiomatosis is an insidiously evolving vascular tumour which must be considered in the presence of vascular lesions. The reference treatment is surgical excision when possible. On the other hand, hasty surgery in diffuse forms remains dangerous given the haemorrhagic nature of this tumour.
