Chlamydia are obligate intracellular eubacteria that are phylogenetically separated from other bacterial divisions. C. trachomatis and C. pneumoniae are both pathogens of humans but differ in their tissue tropism and spectrum of diseases. C. pneumoniae is a newly recognized species of Chlamydia that is a natural pathogen of humans, and causes pneumonia and bronchitis. In the United States, approximately 10% of pneumonia cases and 5% of bronchitis cases are attributed to C. pneumoniae infection. Chronic disease may result following respiratory-acquired infection, such as reactive airway disease, adult-onset asthma and potentially lung cancer. In addition, C. pneumoniae infection has been associated with atherosclerosis. C. trachomatis infection causes trachoma, an ocular infection that leads to blindness, and sexually transmitted diseases such as pelvic inflammatory disease, chronic pelvic pain, ectopic pregnancy and epididymitis. Although relatively little is known about C. trachomatis biology, even less is known concerning C. pneumoniae. Comparison of the C. pneumoniae genome with the C. trachomatis genome will provide an understanding of the common biological processes required for infection and survival in mammalian cells. Genomic differences are implicated in the unique properties that differentiate the two species in disease spectrum. Analysis of the 1,230,230-nt C. pneumoniae genome revealed 214 protein-coding sequences not found in C. trachomatis, most without homologues to other known sequences. Prominent comparative findings include expansion of a novel family of 21 sequence-variant outer-membrane proteins, conservation of a type-III secretion virulence system, three serine/threonine protein kinases and a pair of parologous phospholipase-D-like proteins, additional purine and biotin biosynthetic capability, a homologue for aromatic amino acid (tryptophan) hydroxylase and the loss of tryptophan biosynthesis genes.

In August 1997, a 68-year-old man presented with right pelvic pain. Pelvic computed tomography (CT) and bone scintigraphy showed a huge tumor of the right iliac bone. No other lesion was detected, in spite of a high serum carcinoembryonic antigen level (CEA, 963 ng/ml). In October 1997, the iliac bone tumor was widely resected, and thereafter was diagnosed to be a metastatic adenocarcinoma of unknown origin. After a resection, the serum CEA level dropped as low as 6.4 ng/ml, but gradually went up to 80 ng/ml in October 1999. Next, a lung tumor in the left upper lobe was detected by routine chest CT. In January 2000, a left upper lobectomy was performed, and based on not only the pathological findings but also on an immunohistochemical analysis for napsin A expression, the tumor was diagnosed to be lung adenocarcinoma. The histological and immunohistochemical findings in the previously resected bone lesion were completely compatible with those in the pulmonary tumor, which was finally regarded as M1 lung cancer. In October 2002, the patient was alive without any symptoms, although the serum CEA level was elevated again. We consider this case worthy of presentation because of its unique clinical course as well as the successful long-term survival after surgical treatment alone, for both the primary and metastatic lesions.

The case concerns a 40 years old smoker male, treated for an adenocarcinoma of the left upper lobe, metastatic in muscle extended to the right femur cortex. The patient had first a surgical excision of the mass of the thigh, an intramedullary femoral nailing, and six courses of chemotherapy (cisplatin-vinorelbine) with concurrent thoracic radiotherapy. This treatment led to disease stability. One year later, hematuria revealed a bladder tumor. Cystoscopy with biopsy concluded to an adenocarcinoma pulmonary origin. The PET-scanner showed an uptake of the bladder mass, a hypermetabolic right adrenal gland and subcutaneous left shoulder nodule. The patient had a partial cystectomy associated with enterocystoplasty and left ureteral reimplantation, plus excision of the subcutaneous nodule located in the left shoulder and a right adrenalectomy during the same time. All of the sites were metastasis from adenocarcinoma of pulmonary origin. A salvage chemotherapy was initiated. In the vast majority of cases, bladder metastasis as primary bladder tumours is revealed by hematuria, cystitis or sometimes vague pelvic pain. Our case is a very unusual bladder metastatic site from lung cancer. We will discuss the different procedures and the therapeutic strategies on the basis of the published data.
