Squamous cell carcinoma of the lung is known to metastasize to the bones, but a presentation similar to bone abscess is rare. We encountered a case with bone metastases that mimicked bone abscess, which delayed the diagnosis of squamous cell lung carcinoma. A 67-year-old man presented with a left upper lung infiltrate and lytic lesions on the left first rib and right fifth rib. In consideration of a possible infectious process, cultures of the aspirate from the right fifth rib lesion and blood were taken; however, results were non-specific. Thereafter, bronchoscopic biopsy of the left upper lung nodule and ultrasound-guided biopsy of the right fifth rib lesion yielded a diagnosis of squamous cell lung carcinoma with bone metastases. Metastatic squamous cell lung carcinoma may have imaging characteristics of bone abscess and should be considered in the differential diagnosis of such lesions.

Objectives: To assess the usefulness of sentinel lymph node biopsy (SLNB) in patients with early-stage oral squamous cell carcinoma (OSCC).
Materials And Methods: Seventy-five patients (mean age 62 years) diagnosed with cT1-2 N0 underwent SLNB with Tc, lymphoscintigraphy/SPECT-CT, and gamma probe detection with intraoperative histological examination of the resected sentinel lymph nodes (SLNs). Elective neck dissection was performed during the same surgical procedure of primary tumor resection when malignant deposits were detected microscopically.

Background: Primary ciliary dyskinesia (PCD) is a rare autosomal recessive disorder characterized by dysfunction of motile cilia. While approximately 50 genes have been identified, around 25% of PCD patients remain genetically unexplained; elucidating the pathogenicity of specific variants remains a challenge.
Methods: Whole exome sequencing (WES) and Sanger sequencing were conducted to identify potential pathogenic variants of PCD.

Objective: Margin distance is a significant prognosticator in oral cavity cancer but its role in HPV-related oropharyngeal squamous cell carcinoma [HPV(+)OPSCC] remains unclear. Here, we investigate the impact of margin distance on locoregional recurrence in HPV(+)OPSCC.
Study Design: This is a retrospective cohort study of surgically treated HPV(+)OPSCC patients.

Background: Immune checkpoint inhibitors (ICIs) have been widely applicated for the treatment of patients with advanced esophageal cancer. Skin-related adverse reactions are frequent with ICIs, with toxic epidermal necrolysis (TEN) being a severe and potentially life-threatening cutaneous reaction.
Case Presentation: We present a case of a 70-year-old male with locally advanced esophageal cancer who developed severe toxic epidermal necrolysis (TEN) after 18 days of tislelizumab combined with chemotherapy.

Background: Malignant transformation (MT) of mature cystic teratoma (MCT) has a poor prognosis, especially in advanced cases. Concurrent chemoradiotherapy (CCRT) has an inhibitory effect on MT.
Case Summary: Herein, we present a case in which CCRT had a reduction effect preoperatively.
