[Primary lung adenocarcinoma with ovarian metastasis: a rare presentation of bronchogenic carcinoma]

Ureteral metastasis from pulmonary adenocarcinoma: A case report and literature review

The occurrence of ureteral metastasis from distant primary tumors is uncommon, and appears to be especially rare when it originates from the lungs. In the case presented here, a patient with lumbago and left hydronephrosis was diagnosed with left ureteral metastasis of pulmonary adenocarcinoma after a CT‐guided percutaneous transthoracic needle biopsy of the lung and retroperitoneal laparoscopic left nephroureterectomy. He accepted the targeted therapy because the lung tumor epidermal growth factor receptor mutation (exon19 deletion) was positive, and preoperative staging of lung adenocarcinoma was stage IVA. After an 8‐month follow‐up, he is still alive and well, with no local recurrence or distant metastases. The therapy outcome assessment is stable disease. Although rare, our case has demonstrated that pulmonary adenocarcinoma has the possibility of metastasizing to the ureter, a risk that should be considered in some lung cancer patients.

Ureteral metastasis of non-small-cell lung cancer: a case report

Lung cancer is one of the most common causes of cancer-related death. Most of them already have distant metastasis at the time of diagnosis, but ureteral metastasis is extremely rare. Herein, we reported a lung cancer patient with a metastatic lesion from lung cancer at the distal end of the ureter. The patient is a 61-year-old male diagnosed with invasive adenocarcinoma after the right upper lobe resection and system lymph node dissection surgery. After 12 months of surgery, during routine physical examination, lower abdominal enhanced computed tomography showed there was a soft mass with uneven continuous enhancement at the distal end of the ureter. After the surgery of ureter, the mass was histologically considered to be a metastatic lesion arising from the primary lung cancer.

Ovarian metastasis from non-small cell lung cancer with ALK and EGFR mutations: A report of two cases

Ovarian metastasis from non-small cell lung cancer (NSCLC) is a rare condition. The current study presents the cases of 2 female patients aged 38 and 47 years old, respectively, who were initially diagnosed with NSCLC adenocarcinoma on histology. Both patients initially presented with chest pain and a cough, and subsequently developed ovarian metastases following multiple treatments. The 38-year old patient exhibited an epidermal growth factor receptor mutation, confirmed by scorpion/amplified refractory mutation system analysis from a lung biopsy. The 47-year old exhibited an anaplastic lymphoma receptor tyrosine kinase (ALK) rearrangement, revealed by fluorescence in situ hybridization analysis of the breast tissue biopsy, confirming a diagnosis of ALK rearrangement-positive NSCLC. These patients developed ovarian metastasis in the course of the disease. The current study reports the diagnostic challenges and clinical management of the disease, and provides a review of the literature.

Lung cancer diagnosis on ovary mass: a case report

Metastatic neoplasms to the ovary often cause diagnostic problems, in particular those large ovarian masses mimicking primary tumors. Most of these tumors arise from digestive system or breast, while 37-year-old woman diagnosed as right adnexal complex mass, with a subpleural nodule in the apical part of the left lower lobe, at preoperative chest computed tomography scan. The patient underwent total abdominal hysterectomy with right salpingo-oophorectomy (ovarian mass 220 × 200 mm), total omentectomy, left ovarian biopsy, peritoneal random biopsies, and peritoneal washings for cytology. Pathologic and immunohistochemical examination of ovarian specimen suggested morphology and expression of metastatic lung adenocarcinoma with an intense positivity for Thyroid Transcriptional Factor-1 (TTF-1) and Cytokeratin 7 (CK7) staining. Fine needle biopsy of the lung nodule found epithelioid like malignant cells, confirming the diagnosis of an ovarian metastasis from a primary lung cancer.

This report focused on the clinical and pathologic diagnostic challenge of distinguishing secondary from primary ovarian neoplasms. Issues on useful immunohistochemical stains are also discussed.

Ovarian metastasis from lung cancer: a rare entity

This paper describes a case of ovarian metastasis from lung carcinoma along with its diagnostic challenges, clinical management, and review of the literature. A 49-year-old woman was admitted to our emergency department with complaints of abdominal pain and vomiting. A laparoscopic appendectomy was performed due to acute appendicitis, and a unilateral oophorectomy (left side) via laparoscopy was performed due to the detection of an ovarian mass. Immunohistochemical staining of the ovarian mass revealed that it was reactive to cytokeratin-7 (CK-7) but negative for CK-20. The immunohistochemical and pathological features of the tumor indicated an ovarian metastasis of non-small-cell lung cancer. The patient underwent chemotherapy and was followed up by the oncology department. Her postoperative regular followup of 6 months showed that her condition was stable with no recurrence. The management of female patients with acute abdominal pain and pelvic masses should consist of a multidisciplinary approach to include the diagnosis of any distant organ metastasis.
