A 42-year-old female patient presented with a complete ear amputation resulting from a collision with a machine. The ear was avulsed by blunt trauma, meaning that it was torn away rather than being cleanly cut. Fortunately, the auricular cartilage remained intact and preserved its overall shape despite the amputation. However, the surrounding blood vessels were not suitable for microanastomosis. In the first-stage operation, the auricular cartilage was de-epithelialized and embedded into the postauricular area. Three months later, during the second-stage operation, the embedded auricular cartilage framework was elevated to achieve normal auricular projection. During the postoperative period, a customized mold based on the shape of the patient’s contralateral ear was fabricated using 3D printing technology and applied to the reconstructed ear to refine the contour and achieve a natural appearance. The overall outcome was favorable, with no complications observed during the postoperative care period.

Elastofibroma is a rare soft tissue tumor that most commonly occurs in the subscapular region. It has also been reported in several other anatomical locations. To our knowledge, no previous reports have described elastofibromas in the anterior aspect of the face. A 36-year-old man with intellectual disability was referred to our department for the evaluation of a painless multinodular lesion on the philtrum. The lesion was initially misdiagnosed as a dermatologic condition by the department of dermatology and was treated accordingly, however, it worsened, prompting referral to our department. We performed a surgical excision of the lesion and reconstructed the resulting skin defect with a skin graft. Histopathological examination confirmed the diagnosis of elastofibroma. This case underscores the importance of including elastofibroma in the differential diagnosis of facial neoplasms, particularly when the presentation is phymatous.

A significant portion of newly diagnosed lung cancer cases occurs in populations exposed to air pollution. The World Health Organization has identified air pollution as a human carcinogen, prompting many countries to implement monitoring systems for ambient particulate matter (PM). PM is composed of a complex mixture of organic and inorganic particles, both solid and liquid, that are found in the air. Given the carcinogenic properties of PM and the high prevalence of lung cancer among exposed populations, exploring their connection and clinical implications is critical for effectively preventing lung cancer in this group. This review explores the relationship between ambient PM and lung cancer. Epidemiological studies have demonstrated a dose-response relationship between PM exposure and lung cancer risk. PM exposure induces oxidative stress, disrupts the body’s redox balance, and causes DNA damage, which is a crucial factor in cancer development. Recent findings on the strong correlation between ambient PM and adenocarcinoma highlight the importance of understanding the specific molecular and pathological mechanisms underlying pollution-related lung cancer. In addition to efforts to control emission sources at the international level, a more individualized approach is essential for preventing PM-related lung cancer.
