概括
由于类似的症状和成像结果,诊断鼻瘤具有挑战性. 组织病理学对于准确的诊断至关重要,正如在一个最初被误诊为状细胞癌但被证实为嗅觉神经母细胞瘤的病例中所见.
科学领域:
- 耳鼻喉科 耳鼻喉科 耳鼻喉科
- 病理学 病理学 病理学
- 在瘤学瘤学.
背景情况:
- 鼻瘤很少见,通常具有重叠的临床和放射性特征,使诊断复杂化.
- 血管瘤占鼻瘤的不到2%,从良性到恶性范围.
- 像CT和MRI这样的先进成像可以显示范围,但很难区分良性与恶性血管瘤.
研究的目的:
- 报告一个具有挑战性的鼻瘤诊断病例.
- 强调在鼻瘤诊断中组织病理学评估的重要性.
主要方法:
- 一个42岁的女性的病例介绍,她有一年的鼻腔阻塞,头痛和表.
- 诊断成像包括CT和MRI,以评估高度血管性鼻瘤.
- 手术切除与手术内冷截面分析,其次是确定的术后遗传学.
主要成果:
- 最初的成像表明血管瘤,差异诊断包括良性血管新生瘤和罕见的恶性瘤.
- 冷部位分析表明差异化鼻腔状细胞癌.
- 术后组织病理学最终诊断出嗅觉神经母细胞瘤.
结论:
- 鼻瘤,特别是血管瘤,由于重叠的特征,存在诊断挑战.
- 组织病理学评估对于准确的诊断和最终的治疗计划至关重要.
- 这一案例强调了确定的病理学对罕见鼻瘤的初步评估的关键作用.

9.6K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.
