Abstract Background Spontaneous remission (SR) of cancer is a very rare phenomenon of unknown mechanism. In particular, SR of non-small cell lung cancer (NSCLC) has been scarcely reported. We present the case of a 74-year-old woman with advanced, poorly differentiated NSCLC (highly expressing programmed death ligand-1 [PD-L1]) that progressed despite multiple lines of chemotherapy but then spontaneously remitted. CASE presentation The patient presented with hemoptysis and was diagnosed with stage IIIA poorly differentiated NSCLC via bronchoscopic biopsy. She had an unremarkable medical history and moderate performance status. The initial treatment plan was surgery after neoadjuvant chemotherapy. Despite conventional chemotherapy, follow-up chest computed tomography (CT) showed gradual tumor progression and she decided against further treatment after fifth-line chemotherapy. However, the size of lung mass was markedly decreased on follow-up chest CT one year after ceasing chemotherapy. Also, follow-up positron emission tomography images showed decreased metabolic activity in the lung mass and a percutaneous biopsy specimen from the diminished lung mass revealed no viable tumor cells. A diagnosis of SR of NSCLC was confirmed, and the patient was without tumor progression on follow-up nine months later. Later, PD-L1 immunostaining revealed high positivity (> 99%) in initial tumor cells. Conclusion Our case showing SR of poorly advanced NSCLC refractory to multiple lines of chemotherapy suggested the association between immunity and tumor regression.

Unique Case

Granulomatosis with polyangiitis is a systemic necrotizing vasculitis that affects the small- and medium-sized blood vessels. The diagnosis can be challenging since the clinical and imaging findings have similarities with infection, and malignancy. Serologic and histopathological investigations often help confirm the diagnosis. However, this can be falsely reassuring. We present a unique case of the coexistence of vasculitis and squamous cell carcinoma in the same cavitating lung mass. The case highlights the importance of recognizing changes in disease behaviour early to allow for timely management.

Ischemic Attack

A 60-year-old woman with hypertension, dyslipidemia, and 35–pack-year smoking history is referred for treatment of advanced non–small-cell lung cancer (NSCLC). She initially presented after a transient ischemic attack, when a chest radiograph demonstrated a right lung mass. Computed tomography (CT) of the chest revealed a 5-cm right upper lobe mass, without mediastinal adenopathy, and a 6-cm cystic mass in the spleen. Additional imaging showed no brain metastasis. Endobronchial ulstrasound-guided core biopsies of the lung mass and ipsilateral mediastinal nodes confirmed a poorly differentiated non–small-cell carcinoma. Immunohistochemical stains were positive for napsin A and thyroid transcription factor 1, suggestive of adenocarcinoma ( Fig 1 ). Molecular analysis identified a KRAS G12C mutation. A positron emission tomography (PET) –CT scan demonstrated [18F]fluorodeoxyglucose uptake in the right upper lobe mass and splenic lesion ( Fig 2 A). CT-guided fine-needle aspiration of the splenic lesion was performed and revealed metastatic carcinoma, consistent with the lung primary. Treatment with carboplatin plus pemetrexed was initiated, without bevacizumab because of the recent transient ischemic attack; carboplatin was selected over cisplatin because of similar concerns. The patient received two cycles of chemotherapy without complications, and repeat imaging showed decrease in size of the lung mass and splenic lesion ( Figs 2 B and 2 C). After four cycles of chemotherapy, a chest CT showed ongoing response ( Fig 2 D). Her Eastern Cooperative Oncology Group performance status remained 0.

Pulmonary Actinomycosis

Pulmonary coccidioidomycosis and pulmonary actinomycosis are unheard of as co-pathogens. Infection with these organisms on their own can mimic lung cancer, thus presenting a diagnostic challenge. We present the case of a 75-year-old woman presenting with haemoptysis with a chest CT chest finding of a lung mass suggestive of lung cancer. A diagnosis of concomitant infection by Coccidioides posadasii/immitis and Actinomyces odontolyticus was made based on culture and histopathology results. The patient was successfully treated with a combination of antifungal and antibacterial therapy. This is the first reported case of co-infection by these two microorganisms.
