RESUMEN
Pulmonary osseous metaplasia is a disease in which mature bone is found within the parenchyma of the lung. The current study presents a case of pulmonary osseous metaplasia in a 64-year-old female. The patient was previously diagnosed with transitional cell carcinoma (TCC) of the lower ureter. During a routine check-up, an enhancing basal lung nodule was found on chest computed tomography scan, which was suspected to be metastatic lung disease. The patient underwent a thoracoscopic resection of the nodule. The histopathological examination of the specimen confirmed it to be myeloid osseous metaplasia. The disease usually has no significant complications and can also be found in association with other pulmonary diseases. Very limited information is available on the phenomenon; therefore, there is no exact treatment guide for clinicians to follow. In conclusion, myeloid osseous metaplasia of the lung is a rare finding, and based on this report, it may be associated with TCC.
RESUMEN
Mullerian anomalies occur as a result of errors during embryogenesis. The estimated incidence of these anomalies is around 1% in the general population and 3% in women complaining of suboptimal reproductive outcomes and infertility. A 21-year-old female patient was referred to our hospital due to primary infertility for 18 months. After a proper history, physical examination and further diagnostic steps, including ultrasound and magnetic resonance imaging, a diagnosis of complete septate uterus with septate cervix and longitudinal vaginal septum was made. Following hysteroscopic resection of all the septa and two cycles of ovulation induction, the patient was able to conceive. However, she needed cervical cerclage later due to cervical insufficiency. The baby was delivered at term and was healthy. A uterine, cervical and longitudinal vaginal septum is a unique entity of Mullerian anomalies. Resection of all septa through a hysteroscopic approach resulted in a good outcome for our patient.
RESUMEN
Introduction and importance: Hydatid cysts are seldom identified in cytologic smears and are often incidental. This report highlights a case where fine needle aspiration cytology was unintentionally utilized to diagnose a pulmonary hydatid cyst clinically mistaken for an abscess. Case presentation: A 29-year-old female presented with intermittent respiratory symptoms, including a mild cough and sputum, that she has been complaining of since 2020. A blood investigation revealed an elevated erythrocyte sedimentation rate (25 mm/h), C-reactive protein (>5 mg/dl), and white blood cells (>11×109/l). A high-resolution computed tomography scan of the chest revealed an irregular pulmonary opacity in the right lower lobe with central fluid attenuation, suspecting an abscess or, less likely, a pulmonary neoplasm. The patient underwent fine needle aspiration cytology, which was diagnosed as a hydatid cyst. A thoracotomy was performed, and the cyst was totally excised. Histopathological results of the specimen confirmed the previous diagnosis. Clinical discussion: Various diagnostic modalities have been discussed for diagnosing hydatid cysts, including radiology, serology tests, and fine needle aspiration. These modalities have been evaluated in terms of their respective advantages and drawbacks. Conclusion: Hydatid cysts can be challenging to diagnose based on imaging findings and may be misidentified as abscesses or masses. Despite the risk of anaphylaxis, fine needle aspiration cytology can be a reliable diagnostic method if performed meticulously by experienced radiologists.
RESUMEN
INTRODUCTION: Thoracic outlet syndrome (TOS) caused by superior mediastinal soft tissue mass has never been reported in the literature, the aim of this study is to discuss a case of TOS caused by a superior mediastinal mass in which the histopathological examinations of the mass showed vascular malformation. CASE REPORT: A 45-year-old female presented with left upper limb pain and numbness for three months, associated with swelling and attacks of shortness of breath. Imaging studies showed soft tissue mass involving the superior mediastinum. The condition of the patient deteriorated and the signs and symptoms of TOS became clearer, all provocative tests and nerve conduction studies were positive. The patient underwent thoracic outlet decompression. The patient did not respond and the symptoms deteriorated further. After a multidisciplinary board discussion, the patient was prepared for median sternotomy under general anesthesia. A total resection of the mass was done. The patient was totally relieved a few hours after the operation. DISCUSSION: The etiology of TOS can be multifaceted. Several factors contribute to its onset, and these can be categorized as congenital or acquired. Congenital causes include anatomical anomalies such as a cervical rib, or an elongated transverse process of the cervical vertebrae. These anatomical deviations can reduce the size of the thoracic outlet and make it prone to compression. CONCLUSION: Although it is rare, TOS could be due to superior mediastinal mass and the treatment of choice is total resection either through median sternotomy or thoracoscopic procedure.
