Recently, a case of deep-lobe lipoma with enucleation was reported, but frozen-section biopsy for the confirmation of the malignancy was not done. It has been suggested that lipoma in the deeper tissues should be regarded as a well-differentiated liposarcoma and be treated with wide excision. Our experience is that of a 75-year-old woman who had a mass with fat density in the deep lobe of the right parotid gland, which extended through the parapharyngeal and the buccal spaces. Lumpectomy with frozen-section biopsy was performed, not only preserving branches of facial nerve but also ruling out the malignancy. Frozen-section biopsy showed a lipomatous lesion without malignancy, so further treatment such as total parotidectomy was not needed.

Tubulin Acetylation Enhances Microtubule Stability in Trabecular Meshwork Cells Under Mechanical Stress.

Purpose: To study the roles of tubulin acetylation and cyclic mechanical stretch (CMS) in trabecular meshwork (TM) cells and their impact on outflow pathway physiology and pathology.
Methods: Primary TM cell cultures were subjected to CMS (8% elongation, 24 hours), and acetylated α-tubulin at lysine 40 (Ac-TUBA4) was assessed by western blotting and immunofluorescence. Enzymes regulating tubulin acetylation were identified via siRNA-mediated knockdowns of ATAT1, HDAC6, and SIRT2.

Background: Penile cancer is a rare malignancy treated via various surgical techniques guided by disease stage and grade with current guidelines suggesting partial or total penectomy for those with pT2 or greater. We report a case of a patient with pT2 squamous cell carcinoma (SCC) of the penis who underwent circumcision with left partial-glansectomy and resection of preputial mass with good oncological control while providing good urinary and sexual function.
Case Description: An 82-year-old male presented to the clinic due to a mass that doubled in size in an 8-month timeframe.

Introduction: Clear cell hidradenoma (CCH) is a rare type of benign breast tumor that may undergo malignant transformation in a few cases. It clinically manifests as a painless breast mass, and may include nipple discharge. Complete surgical excision with adequate safety margins is the primary treatment.

Objectives: Liver transplant is the most effective therapeutic option for patients with end-stage liver disease, nonalcoholic steatohepatitis, and acute liver failure. We evaluated whether the percentage of hepatic fat percentage affected transplant outcomes to determine whether livers with varying severity of macrosteatosis should be considered suitable for donation.
Materials And Methods: We analyzed data from 381 patients with liver failure who received liver transplant at Montaseriyeh Hospital in Mashhad, Iran, between 2013 and 2022.

Introduction: During revision surgery for the management of patients presenting with long-bone upper extremity nonunion, it is crucial to rule out fracture-related infection (FRI). This is especially true if there are clinical signs suggestive of FRI, or if there is a history of prior FRI, open wound fracture, or surgery. This study aimed to determine the efficacy of frozen section analysis (FSA) in providing real-time diagnosis of FRI in patients with upper-limb long-bone nonunion undergoing revision surgery.
