Intramuscular hemangiomas of the masseter muscle are uncommon tumors and therefore can be difficult to accurately diagnose preoperatively, due to the unfamiliar presentation and deep location in the lateral face. A case of intramuscular hemangioma of the masseter muscle in a 66-yearold woman is presented. Doppler ultrasonography showed a 34× 15 mm hypoechoic and hypervascular soft tissue mass in the left masseter muscle, suggesting hemangioma. The mass was excised via a lateral cervical incision near the posterior border of the mandibular ramus. The surgical wound healed well without complications.

In the face, the nose plays an important role in both function and appearance. Among the subunits on the nose, the alar is a critical nasal structure of high aesthetic value. Previously, many surgeons have insisted that structural support should be added to the reconstruction of alar and particularly so in the case of a full-thickness defect. In a 58-year-old male patient who had a third-degree burn injury and full-thickness defect in most of the left nasal alar, forehead flap surgery alone was successfully performed without structural support.

PURPOSE: The goal of this study was to evaluate the fracture resistances of various monolithic crowns fabricated by computer-aided design and computer-aided manufacturing (CAD/CAM) with different thickness. MATERIALS AND METHODS: Test dies were fabricated as mandibular molar forms with occlusal reductions using CAD/CAM. With different occlusal thickness (1.0 or 1.5 mm), a polymer-infiltrated ceramic network (Enamic, EN), and zirconia-reinforced lithium silicate (Suprinity, SU and Celtra-Duo, CD) were used to fabricate molar crowns. Lithium disilicate (e.max CAD, EM) crowns (occlusal: 1.5 mm) were fabricated as control. Seventy crowns (n=10 per group) were bonded to abutments and stored in water for 24 hours. A universal testing machine was used to apply load to crown until fracture. The fractured specimens were examined with a scanning electron microscopy. RESULTS: The type of ceramics and the occlusal thickness showed a significant interaction. With a recommended thickness (1.5 mm), the SU revealed the mean load similar to the EM, higher compared with those of the EN and CD. The fracture loads in a reduced thickness (1.0 mm) were similar among the SU, CD, and EN. The mean fracture load of the SU and CD enhanced significantly when the occlusal thickness increased, whereas that of the EN did not. CONCLUSION: The fracture loads of monolithic crowns were differently influenced by the changes in occlusal thickness, depending on the type of ceramics. Within the limitations of this study, all the tested crowns withstood the physiological masticatory loads both at the recommended and reduced occlusal thickness.

Basal cell carcinoma is a malignant epithelial neoplasm of the skin and the most common human skin cancer. It is generally associated with a good prognosis. In this case report, a giant basal cell carcinoma of the nodulo-ulcerative type showing wide ulceration with marginal multiple small nodules, is presented. It was trapezoidal in shape, having dimensions of 7 cm at the greatest basal width, 6 cm vertically with different anterior and posterior margin dimensions, and 5 cm horizontally at the top margin. After wide excision of the lesion including 5–10 mm safety margins, the wound was reconstructed with a local skin flap and split-thickness skin graft. The reconstructed wound healed well without recurrence for 1 year.

Background/Aims:
Cirrhosis is the most important risk factor of hepatocellular carcinoma (HCC), and patients with cirrhosis are recommended to receive semiannual surveillance for early HCC detection. However, early cirrhosis is often asymptomatic and can go undiagnosed for years, leading to underuse of HCC surveillance in clinical practice. We characterized the frequency and associated factors of unrecognized cirrhosis in a national sample of patients with HCC from the United States.
Methods:
HCC patients aged 68 years and older, diagnosed during 2011 to 2015 were included from the SEERMedicare Linked Database. If cirrhosis was diagnosed within 6 months immediately preceding HCC diagnosis or after HCC diagnosis, cases were categorized as unrecognized cirrhosis. Factors associated with unrecognized cirrhosis were identified using logistic regression analyses. Factors associated with overall survival were evaluated using Cox regression analyses.
Results:
Among 5,098 HCC patients, 74.8% patients had cirrhosis. Among those with cirrhosis, 57.4% had unrecognized cirrhosis, with the highest proportion (76.3%) among those with NAFLD-related HCC. Male sex (aOR: 2.12, 95% CI: 1.83–2.46), non-Hispanic Black race (aOR: 1.93, 95% CI: 1.45–2.57), and NAFLD etiology (aOR: 4.46, 95% CI: 3.68–5.41) were associated with having unrecognized cirrhosis. Among NAFLD-related HCC patients, male sex (aOR: 2.32, 95% CI: 1.71–3.14) was associated with unrecognized cirrhosis. Unrecognized cirrhosis was independently associated with worse overall survival (aHR: 1.17, 95% CI: 1.08–1.27) compared to recognized cirrhosis.
Conclusions
Unrecognized cirrhosis is common in NAFLD-related HCC, particularly among male and Black patients, highlighting these groups as important intervention targets to improve HCC surveillance uptake and outcomes.
