With the popularization of chest computed tomography examination in physical examination, the detection rate of multiple pulmonary nodules has significantly increased. However, there are no unified guidelines or consensus for the diagnosis and treatment of multiple pulmonary nodules, and the clinical diagnosis and treatment of such patients are often inadequate or excessive. Therefore, it is of great clinical significance to attach importance to the moderate diagnosis and treatment of multiple pulmonary nodules and formulate unified clinical practice standards for the prevention of lung cancer and the diagnosis and treatment of multiple pulmonary nodules.

Lung cancer leads to the highest cancer-related morbidity and mortality worldwide. With the development of multi-slice spiral computed tomography technology and the implement of lung cancer screening, more and more lung nodules have been discovered, many of which are multiple pulmonary nodules. These pulmonary nodules are usually diagnosed as multiple primary lung adenocarcinomas from a pathological perspective. For multiple nodules with different imaging features, the preferred treatment methods are different, and the treatment of each lung nodule is still controversial. In recent years, the interactions between multiple lesions and the evolution of the lesions as well as the inter-tumoral and intratumoral homogeneity and heterogeneity of the genomics also arouse attention. Our review gathered the research progress in multiple pulmonary nodules from the points of histopathology, genomics and surgical management.

A 9-year-old boy was admitted to Xiangya Hospital due to pain after trauma in the left lower limb for 5 days and fever with generalized pain for 2 days. The results of X-ray of the left lower limb were normal. Pulmonary computed tomography (CT) showed multiple pulmonary nodules in both lungs. Adrenal CT showed marked enlargement of the left adrenal gland. The patient also experienced generalized herpes and intermittent delirium and had a blood pressure up to 155/93 mm Hg. He was transferred to our hospital with a suspected diagnosis of pheochromocytoma. On admission, the patient had a blood pressure of 86/44 mm Hg, sporadic maculopapule and herpes, touch-evoked pain, exposure of superficial veins, white pus coating on the right side of the tongue, and tension in the abdominal muscle. No skin damage was observed in the left lower limb, and the patient was forced to be in the extending position and experienced significant swelling below the knees. Laboratory examination showed a reduction in platelet count, hypoproteinemia, a significant increase in creatase, a C-reactive protein level of 348 mg/L, and a procalcitonin level of >100 ng/mL. Thoracoabdominal and pelvic CT showed multiple patchy and nodular lesions in both lungs, which had an undetermined nature, as well as an enlarged spleen. The tests of puncture fluid from the left knee joint and the periosteum of the left tibia, blood culture, and bone marrow culture all showed methicillin-resistant Staphylococcus aureus. The patient was given anti-shock treatment, anti-infective therapy with vancomycin, debridement and continuous irrigation/drainage of osteomyelitis lesions in the left tibia, but the patient still experienced recurrent shivering and severe fever and increased subcutaneous and pulmonary nodules. Linezolid was added on day 8 after admission, and the patient's body temperature returned to normal on day 24 after admission. Subcutaneous and pulmonary nodules were gradually reduced and disappeared. The patient was treated for 2 months and then evaluated as cured.

Syphilis is a sexually transmitted disease caused by Treponema pallidum. The prevalence of this disease has recently increased worldwide. However, pulmonary involvement in secondary syphilis is extremely rare. A 51-year-old heterosexual male patient presented with multiple pulmonary nodules with reactive serology from the Venereal Disease Research Laboratory test and positive fluorescent treponemal antibody absorption testing. A hematogenous metastatic malignancy was suspected and an excisional lung biopsy was performed. Histopathological examination showed only central necrosis with abscess and plasma cell infiltration, but no malignant cells. The patient reported sexual contact with a prostitute 8 weeks previously and a penile lesion 6 weeks earlier. Physical examination revealed an erythematous papular rash on the trunk. Secondary syphilis with pulmonary nodules was suspected, and benzathine penicillin G, 2.4 million units, was administered. Subsequently, the clinical signs of syphilis improved and the pulmonary nodules resolved. The final diagnosis was secondary syphilis with pulmonary nodular involvement.
