A very rare case of eyelid metastasis originating from lung adenocarcinoma

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.

Pulmonary Adenocarcinoma Metastatic to Periocular Skin and Orbital Tissue Presenting as Orbital Cellulitis

A 56-year-old man presented with a periorbital subcutaneous mass and ipsilateral visually significant orbital inflammation that was refractory to broad-spectrum antibiotics. Orbitotomy with biopsy revealed the diagnosis of metastatic lung cancer, and the patient was initiated on systemic chemotherapy and adjuvant radiation. This is the first report of pulmonary adenocarcinoma metastatic simultaneously to the periocular cutaneous and intraorbital soft tissues. Atypical periorbital and orbital inflammation may be the initial presentation of occult malignancy and require a high index of suspicion and tissue biopsy for diagnosis and life-saving management.

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.
