Keratin granulomas in the peritoneum are a rare finding with multiple etiologies and can be especially challenging for both the pathologist and the surgeon when these lesions are grossly visible. We report a case of a unique frozen section diagnostic scenario of evaluation of keratin granulomas in the peritoneum of a 47-year-old woman in the setting of multiple potential culprits: endometrial endometrioid adenocarcinoma following fertility sparing treatment, and a concurrent dermoid cyst. We discuss the various etiologies of keratin granulomas in the peritoneum, mechanism of their formation, diagnostic significance, as well as implications of fertility sparing treatments. To the best of our knowledge, this is the only case of keratin granulomas in the peritoneum with multiple distinct potential pathologic culprits as well the only case following fertility sparing treatment.

Introduction: Keratinous cysts are benign lesions that primarily affect the skin but can occasionally involve bones, presenting a diagnostic challenge due to their rarity and varied manifestations.
Case Report: We present a case of a 65-year-old male farmer who presented with swelling and persistent pain in the right foot, particularly over the third toe. The patient had a history of trivial trauma and previous incision and drainage for a foot swelling.

Diffuse keratinization of peritoneum can be seen in various neoplastic and non-neoplastic diseases. This exuberant keratinization exhorts a granulomatous response with multinucleated giant cell reaction. In malignancy of ovary or endometrium they mimic tumor deposits, sometimes leading to erroneous upstaging.

To investigate the clinicopathological features, treatment-effect assessment and prognosis of SMARCA4-deletion non-small cell lung cancer (NSCLC) that was treated with neoadjuvant therapy. Eleven consecutive cases of SMARCA4-deletion NSCLC treated with neoadjuvant therapy in Guangdong Provincial People's Hospital, Guangzhou, China from January 2007 to October 2024 were collected. Their clinicopathological features, pathological assessment of treatment effect, and prognosis were retrospectively analyzed.

Epidermoid cysts are rare intracranial lesions comprising approximately 1% of all brain tumors, with petrous apex involvement accounting for 4%-9% of cases. These congenital lesions arise from ectodermal remnants during neural tube closure, while acquired cases may result from trauma or chronic middle ear pathology. Clinical presentation is variable and depends on the lesion's location and impact on surrounding neurovascular structures, with cranial nerve dysfunction being the most common symptom.

Beyond enchondromas, the most common bone tumors of the hand, there are numerous less common benign bone tumors and mimickers with which orthopaedic and hand surgeons should be familiar. These include other benign cartilage tumors, cystic lesions, osteogenic tumors, giant cell tumor, and fibrous dysplasia. Particularly unique lesions include bizarre parosteal osteochondromatous proliferation (Nora lesion), florid reactive periostitis, turret exostosis (acquired osteochondroma), giant cell reparative granuloma (solid aneurysmal bone cyst), and epidermoid cyst.
