Thoracic Endometriosis-A Rare Cause of Haemoptysis

Endometriosis of the lung: A case report and review of literature

BACKGROUND

Lung endometriosis is an extremely rare gynecological disease. Current literature reports suggest that the majority of patients will present with only generic symptoms, such as hemoptysis, pneumothorax, and hemopneumothorax, which often leads to misdiagnosis. To date, there are 18 case reports of lung endometriosis that describe the clinical manifestation, imaging changes, treatment, and prognosis of the disease. To provide further insights into this rare disease, we present a new case report and a brief review of pulmonary endometriosis.

CASE SUMMARY

We report here about a 19-year-old woman who was admitted to the hospital for repeated catamenial hemoptysis over a 3-mo period. computed tomography (CT) imaging during menstruation revealed patchy high-density shadows, approximately 0.5 cm³ in size, in the right middle lobe of the lung. The patient’s hemoptysis and changes in the CT scans resolved after menstruation. Thoracoscopic right middle lobectomy, right lower lung repair, and closed thoracic drainage were performed. Postoperative histopathology confirmed lung endometriosis. There was no recurrence of symptoms at the 6 mo follow-up.

CONCLUSION

We propose diagnosing lung endometriosis by thoroughly taking reproductive history, clinical details, imaging, and histopathology followed by treatment with surgical resection.

Cyclical Hemoptysis and Pelvic Pain in a Young Female: A Sign of Thoracic Endometriosis Syndrome

Distant autoimplantation of endometrial implants presents with signs and symptoms specific to the affected site. The constellation of cyclical hemoptysis, pleuritic chest pain, dyspnea, or cough in the right gynaecologic setting should raise concern for thoracic endometriosis syndrome (TES). Although extra-pelvic implications of endometriosis are well known, TES is exceedingly rare. We present an unusual case of aggressive TES that re-emerged after a period of latency despite suppressive therapy, making the case for future studies to establish surveillance schedules and advanced therapies. As these implants become sizable, they require a combination of medical and surgical therapies often with psychological support. This case illustrates the importance of prompt diagnosis and a multidisciplinary approach to TES.

Recurrent unilateral hemorrhagic pleural effusion: A rare manifestation of thoracic endometriosis syndrome

Unilateral recurrent pleural effusions are commonly encountered in critical care practice. Relevant clinical history, physical examination, radiology, and diagnostic thoracentesis usually identify the cause of pleural effusion in most cases. Thoracoscopy or video-assisted thoracic surgery may be required in selective cases. We report a case of 32-year-old female with recurrent unilateral hemorrhagic pleural effusion that was the presenting feature of thoracic endometriosis syndrome.

Catamenial pneumothorax caused by thoracic endometriosis

BACKGROUND

Thoracic endometriosis syndrome is a rare form of extrapelvic endometriosis characterized by the presence of functioning endometrial tissue in pleura, lung parenchyma, and airways, associated with a high rate of infertility.

CASE REPORT

We have reported a case of successful management and treatment of thoracic endometriosis syndrome that occurred in a 37-year-old female patient. She underwent thoracoscopic resection of the lesion. During follow-up, we revealed the recurrence of a previously surgically treated thoracic endometriosis. She was initially treated with a gonadotropin-releasing hormone agonist; subsequently this was replaced by a prophylactic treatment with Dienogest.

CONCLUSION

The diagnosis of thoracic endometriosis is challenging. The first line of treatment is medical, whereas the surgical treatment is performed secondly. Moreover, surgical treatment can lead to a significant rate of recurrence, often reduced by a coadjutant medical treatment.

A case report of thoracic endometriosis - A rare cause of haemothorax

•

The diagnosis of thoracic endometriosis is complicated, because it has no specific symptoms and signs, and often delayed. TES should be suspected in a reproductive age woman with exacerbating symptoms during the menstruation.

•

TES treatment should be started with medicine. If medical therapy fails, surgical treatment should be performed.

•

Our case report shows that TES may be the cause of dangerous situation when an urgent operation must be performed. It is the first case of TES that has required urgent surgical treatment in our hospital in past fifteen years. Not all clinicians know that TES sometimes might complicate to pneumothorax or massive bleeding, which might cost a patient’s life. We suggest performing VATS as soon as possible for reproductive age woman with unknown aetiology of pneumothorax or haemothorax to find out the lesions in pleural cavity and start appropriate treatment on time.

Introduction

The presence of endometrial tissue in airways, pleura and lung parenchyma is called thoracic endometriosis syndrome (TES). It is a rare pathology, and typically consists of catamenial pneumothorax, haemothorax, haemoptysis, and pulmonary nodules. We report a case of a 36-year-old woman with thoracic endometriosis causing catamenial haemothorax.

Conclusions

The diagnosis of thoracic endometriosis is complicated and often delayed. TES should be suspected in a reproductive age woman with exacerbating symptoms during the menstruation.

Treatment may be medical and surgical.

Pulmonary Endometriosis which Probably Occurred through Hematogenous Metastasis after Artificial Abortion

Pulmonary endometriosis (PEM) is a rare disease characterized by the proliferation of ectopic endometrial tissue in the lungs, which presents as catamenial hemoptysis. A 20-year-old-woman was admitted for repeated hemoptysis. Chest CT revealed a ground-glass opacity that appeared consistently with her menstrual cycle. Our detailed inquiry revealed a history of artificial abortion, which was followed by the use of oral contraceptives and catamenial hemoptysis after the discontinuation of these medications. Surgical removal was performed and histopathological examinations confirmed PEM. This clinical course suggested hematogenous metastasis. An inquiry regarding the patient's history of uterine procedures and use of oral contraceptives was suggestive for the diagnosis of this disease.
