Hepatocellular carcinoma (HCC) remains a leading cause of cancer-related deaths worldwide, with poor clinical outcomes due to challenges in early detection and limited efficacy of current treatments such as receptor tyrosine kinase inhibitors and immunotherapy. HCC exhibits significant heterogeneity at both histopathological and molecular levels, complicating its management but offering potential for personalized therapeutic approaches. This review outlines the morpho-molecular heterogeneity of HCC and summarizes various histological subtypes, including steatohepatitic, clear cell, macrotrabecular-massive, scirrhous, lymphocyte-rich, and fibrolamellar HCCs. Each subtype possesses distinct clinical, histological, and molecular features; for instance, steatohepatitic HCC is associated with metabolic dysfunction and shows IL-6/JAK/STAT activation, while clear cell HCCs often have IDH1 mutations and favorable prognosis. The macrotrabecular-massive subtype is linked to poor outcomes and TP53 mutations, whereas scirrhous HCCs express stemness markers and have TSC1/TSC2 mutations. Lymphocyte-rich HCCs are characterized by immune cell infiltration and better prognosis. CTNNB1-mutated HCCs show specific morphological features and may benefit from targeted therapies. Understanding these subtypes and associated molecular alterations is crucial for developing effective diagnostic and therapeutic strategies, including potential predictive biomarkers and personalized treatments. Additionally, the identification of patterns like vessels-encapsulatingtumor-clusters offers prognostic implications and may guide therapeutic decisions. Recent molecular studies have enhanced our comprehension of HCC heterogeneity, laying the groundwork for more personalized approaches. Pathologists play a vital role in recognizing these subtypes, aiding in prognosis prediction and treatment planning. Advances in digital pathology and artificial intelligence may further facilitate biomarker research, ultimately improving patient outcomes in HCC management.

Hyperbaric oxygen therapy (HBOT) was conducted on two male patients with chronic prostatitis/chronic pelvic pain syndrome who were resistant to conventional medical therapies. Both patients underwent 20 sessions of 100% oxygen inhalation (2.0 atmosphere absolute for 90 min/day, five days/week for four weeks) in a hyperbaric chamber. The follow-up period was three months. Although the patients reported a slight improvement in the pain domain of the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) after HBOT, no changes were noted in the other domains of NIH-CPSI and International Prostate Symptom Score. No adverse events were encountered during or after HBOT.

Purpose: To investigate the prevalence of anogenital warts (AGW) caused by human papillomavirus in men and the characteristics and changes of the disease in Korea. Materials and Methods: From 2007 to 2018, male AGW corresponding to the International Classification of Disease-10 A63.0 were targeted. Through a big data analysis of the Health Insurance Review & Assessment Service, data of patients diagnosed with AGW as either the main or secondary diagnosis were extracted. The overall prevalence and prevalence by age were calculated through the population by year and the population by 5-year-old unit of the National Statistical Office. Additionally, the amount accrued through the disease code was confirmed and compared as AGW-related medical expenses. Results: The annual number of patients increased by 3.5 times from 32,709 in 2007 to 114,734 in 2018. Additionally, the annual prevalence increased by 3.34 times from 132.83 per 100,000 to 443.57. The age-specific prevalence was the highest among the 25-to 29-year age group. The highest prevalence was observed in the 25- to 29-year age group in 2018 (1,492.15 per 100,000), and the lowest was noted in the 10- to 14-year age group in 2014 (7.28 per 100,000). AGW-related medical expenses increased by approximately 9.76 times from US$ 2,789,215.1 in 2007 to US$ 27,227,254.9 in 2018. Conclusions In Korea, cases of male AGW are increasing yearly, with the 25- to 29-year age group having the highest prevalence.Medical costs related to AGW are also increasing tenfold. For male AGW, further studies and national interventions are needed.
