Cerebrospinal fluid (CSF) rhinorrhea is a condition characterized by leakage of CSF from skull base through the nostril(s). It is commonly associated with trauma, surgery, infections of paranasal sinuses/skull base, and intracranial and skull base tumors. Among malignant causes, lung cancer is rarely associated with CSF rhinorrhea. Herein, we report the case of a 51-year-old lady who was initially diagnosed with metastatic lung adenocarcinoma (LUAC) with anaplastic lymphoma kinase (ALK) rearrangement and initiated on treatment with alectinib. She had good clinicoradiological response, but on follow-up developed CSF rhinorrhea that required surgical correction. We also discuss the proposed mechanisms associated with occurrence of CSF rhinorrhea in the setting of metastatic ALK-rearranged LUAC.

Background: Anaplastic lymphoma kinase (ALK) immunohistochemical staining on formalin-fixed paraffin-embedded tissue or cell blocks (CB) has been reported as an effective alternative to fluorescence hybridization in situ (FISH) for the detection of ALK gene rearrangement. However, CB frequently lack adequate cellularity even when the direct smears are cellular. This study aims to assess the utility of ALK immunocytochemical (ICC) staining on direct smears using the cell transfer (CT) technique for the detection of ALK rearrangement. Methods: Fine-needle aspiration (FNA) cases of lung adenocarcinoma in which the ALK status had been determined by FISH on CB or a concurrent biopsy were identified. ICC staining for ALK was performed on alcohol-fixed Papanicolaou-stained direct smears using the CT technique. ALK immunoreactivity was evaluated using a modified semiquantitative scale. Results were compared with those of FISH. Results: A total of 47 FNA specimens were included. Five of 7 FISH-positive cases showed positive ALK ICC staining (71.4%), and 39 of 40 FISH-negative cases were negative on ALK ICC staining (97.5%). The overall correlation between ALK ICC and FISH was 93.6%. Conclusion: ICC performed on FNA smears using the CT technique is an alternative method for the assessment of ALK rearrangement, especially when CB lack adequate cellularity.

This report concerns a patient with skeletal muscle metastases due to lung adenocarcinoma harbouring an echinoderm microtubule-associated protein-like-4 (EML4)-anaplastic lymphoma kinase (ALK) rearrangement, who was successfully treated with lorlatinib after resistance to alectinib. A right lower lobectomy based on a diagnosis of lung adenocarcinoma was performed on a 77-year-old Japanese woman. After 7 months of surgical resection, a mass in the right calf was observed. A fine-needle aspiration biopsy from the mass was performed and the mass was diagnosed as metastatic adenocarcinoma harbouring EML4-ALK rearrangement. Alectinib was administered for 10 months. Then, administration of lorlatinib, an ALK tyrosine kinase inhibitor classified as third generation, was initiated after resistance to treatment with alectinib. After starting treatment with lorlatinib, the gastrocnemius tumour diminished and has maintained a stable condition. Our case suggests that EML4-ALK positive lung adenocarcinoma is treatable with lorlatinib after resistance to treatment with alectinib.

Epidermal growth factor receptor ( EGFR) mutations and anaplastic lymphoma kinase ( ALK) rearrangements are considered mutually exclusive in non-small cell lung cancer (NSCLC), especially in lung adenocarcinoma (LUAC). However, sporadic cases harboring concomitant EGFR and ALK alterations have been increasingly reported. There is no consensus opinion regarding the treatment of patients positive for both molecular alterations. NSCLC with EGFR/ ALK coalterations should be separated into two subtypes: unifocal and multifocal LUAC. Here, we present an overview of the available literature regarding this rare group of patients to provide useful suggestions for therapeutic strategies.
