“…Li et al. reported a pedicled mass in the bladder wall, which was consistent with primary bladder cancer and difficult to distinguish ( 12 ). Therefore, if bladder metastasis is suspected, cystoscopy and transurethral resection (TUR) biopsy are necessary.…”

“…Thus, the combination of CK7 and CK20-related results may provide a preliminary diagnosis of the primary site. For example, CK7+/CK20+ or CK20- phenotypes suggest lung or bladder as sites of the primary lesion, and CK7-/CK20+ phenotypes suggest a gastrointestinal origin (although some colorectal cancers may express CK7 and some bladder tumors may be CK20+) ( 12 ). Thyroid transcription factor 1 (TTF-1), which is expressed in primary lung adenocarcinoma, is highly sensitive and specific.…”

“…In the auxiliary examination, color ultrasound and CT often indicate focal or diffuse thickening of the bladder wall, which is difficult to distinguish from primary bladder cancer (10,11).

Therefore, if bladder metastasis is suspected, cystoscopy and transurethral resection (TUR) biopsy are necessary.…”

BackgroundLung cancer is the most common cause of cancer-related mortality in the world. Unfortunately, more than 50% of patients have already metastasized at the time of diagnosis, contributing to morbidity and mortality. Common sites of metastasis are adrenal glands, liver, bone, and brain. Bladder metastasis is rare and should prompt a careful differential consideration of primary bladder cancer.Case descriptionHere, we report a 72-year-old female who went to the hospital for “gross hematuria for one day”. Cystoscopy showed space-occupying lesions in the bladder. During the general CT examination, space-occupying lesions in the lower lobe of the lung were found. Peripheral lung cancer with multiple lymph node metastases, pulmonary metastasis, and left pleural effusion were considered. Transurethral cystoscopic resection of the bladder tumor and pleural effusion cell block examination were performed to clarify the diagnosis. Combined with morphological and immunohistochemical results, both pathological results supported a diagnosis of lung adenocarcinoma metastasis, and gene detection was carried out. EGFR, ALK, and ROS-1 were negative. According to the genetic testing results, there was no corresponding targeted drug, so we administered chemotherapy, and one-year survival was achieved, which was better than expected based on other studies.ConclusionThis paper describes a case of lung adenocarcinoma metastatic to the bladder and includes a review of the literature to provide clinicians with diagnostic and treatment experience and help avoid misdiagnosis and mistreatment.

“…1 PSCC mostly manifests with a unique intrabronchial papillary growth pattern. 2 Although the preferred therapy is surgery for such benign tracheal tumors, our previous publication (Jiang et al) showed that bronchoscopic interventions (such as using Endostar and cisplatin) are important and effective alternatives for patients who are not candidates for surgical resection. 3 A variety of techniques, such as electrocautery, argon plasma coagulation (APC), laser, and cryotherapy through a flexible or rigid bronchoscope, have been used to treat tracheobronchial tumors.…”

Squamous cell carcinoma (SCC) is a malignant epithelial tumor originating from the bronchial epithelium that shows keratosis and/or intercellular bridges. Papillary squamous cell carcinoma (PSCC) is an extremely rare subtype of SCC that manifests with a unique intrabronchial papillary growth pattern. Surgical resection is still the first recommendation for localized noninvasive SCC. However, some patients are not candidates for surgical resection. With the development of interventional pulmonology, bronchoscopic interventional therapy has played a key role in the treatment of central airway tumors. Here, we report a case of noninvasive PSCC in the airway treated with an electric snare, argon plasma coagulation (APC), and cryotherapy. After removing the tumor by electrotomy, cryotherapy, and APC, the tumor was injected with Endostar 15 mg (3 ml) and cisplatin 20 mg (diluted to 3 ml with 0.9% normal saline) in six separate sites, once every 21 days. The tumor was eliminated, and the treatment was stopped after four treatment cycles. During the 1-year follow-up, there was no recurrence of PSCC in the airway. In this case, submucosal injections of Endostar combined with cisplatin was a feasible and effective endoscopic method for treating a low-grade intratracheal malignant tumor.
