METASTASIS MASQUERADING AS LUNG ABSCESS-A RARE CASE REPORT

Abstract :

Co– existence of multiple malignancies in a patient with different cell line is a very rare presentation. These type of occurrence is probably due to exposure to various carcinogens and genetic mutation mediating the carcinogenesis. There are various case reports in the literature about genetic predisposition due to mutation involving hereditary non–polyposis colorectal cancer (HNPCC) with synchronous and metachronous occurrence of malignancies of renal, ureteral, ovarian and endometrial cancers. Such patients present with varied clinical presentation which may often be misleading causing a delay in diagnosis and progression of staging of the disease. Here we report a case of 75–year–old male who has underwent radical cystectomy for transitional cell carcinoma of bladder 10 years ago, on preoperative pulmonary risk assessment of thyroidectomy with follicular carcinoma of thyroid, Chest radiograph revealed a cavitating lesion with air–fluid level in the right upper lobe of lung which was initially thought to be aspiration pneumonia complicated with lung abscess following an event of cereovascular accident 2 months ago from the current presentation. Bronchoscopic examination revealed no evidence of intraluminal malignancy and onchoscopic ush and wash from right upper lobe was negative for malignancy. CT guided biopsy of the right upper lobe lesion showed transitional cell carcinoma deposits from primary carcinoma of bladder. This case presented for sensitizing on the rare occurrence of dual malignancies in a patient with rare presentation of carcinomatous deposits from TCC of bladder presenting as cavitory lesion.
