A case of nevoid basal cell carcinoma syndrome dominated by facial basal cell carcinoma / 中南大学学报(医学版)

Nevus-like basal cell carcinoma syndrome (NBCCS) is a rare autosomal dominant disease characterized by the occurrence of multiple maxillofacial keratocysts, basal cell carcinoma, child medulloblastoma, and various skeletal and soft tissue dysplasia. In 2020, a patient with NBCCS dominated by facial basal cell carcinoma was admitted to Xiangya Hospital of Central South University. The patient was an elderly woman. Ten years ago, the systemic mass appeared, especially on the face, but it was not treated. Later, these masses gradually increased in volume and number, and showed invasive properties. The nasal mass was broken and suppurated, seriously affecting the patient's life quality. The patient came to the hospital to improve the symptoms. Staphylococcus aureus and Providencia rettgeri were cultured in the patient's nasal secretions. Nasal sinus enhanced MRI showed that the subcutaneous soft tissue of the right cheek and the anterolateral mucosa of the left nasal cavity were invaded, indicating multiple malignant skin lesions. After admission, local anesthesia was performed and some masses were removed. Pathological examination of the mass showed basal cell carcinoma. After general anesthesia, multiple masses were resected. The postoperative pathological examination showed that multiple basal cell carcinoma invaded the deep dermis near subcutaneous fat layer. Combined with the results of clinical and immunohistochemical examination, the patient was diagnosed as NBCCS. There were no clear tumor thrombus in the vessel and no nerve invasion. No recurrence or new tumor was found after 1 year follow-up. The incidence rate of NBCCS is low and clinical symptoms are different. The patient's life quality is poor and the patient needs long-term individualized treatment.

Effect of progesterone on the pathogenesis and development of hemangioma in nude mice / 中南大学学报(医学版)

To explore the role of progesterone in the pathogenesis and development of hemangioma in nude mice.
 Methods: The hemangioma model was established. Progesterone was injected intramuscularly at different doses (0.2, 0.4, and 0.8 mg/d) for one week. Camellia oil (0.4 mL/d) was injected intramuscularly as control. The size of hemangioma was observed dynamically. The subcutaneous implants were harvested on the 14th and 28th days. The expression of vascular endothelial growth factor in the tumor tissues were evaluated using immunohistochemistry and microvessel density (MVD) was counted under the microscope.
 Results: On the 14th day, the expression of vascular endothelial growth factor (P0.05). The expression of vascular endothelial growth factor (P<0.01) was lower, and MVD (All P<0.05) were less in the middle-dose and high-dose progesterone group than those in the control and low-dose progesterone group.
 Conclusion: Progesterone promotes angiogenesis via upregulation of vascular endothelial growth factor expression, promotion of hemangiomas proliferation, suggesting that excessive progesterone supplementation may be one of the initial factors for early hemangioma formation.
