We report a case of cacogeusia, specifically metallogeusia (a perceived metallic or bitter taste) following pine nut ingestion. A 36-year-old male presented with cacogeusia one day following ingestion of 10-15 roasted pine nuts (genus: Pinus). Symptoms became worst on post-exposure day 2 and progressively improved without treatment over 5 days. There were no other symptoms and physical examination was unrevealing. All symptoms resolved without sequalae. We contemporaneously report a rise in pine nut-associated cacogeusia reported online during the first quarter of 2009, and a significant rise in online searches related to pine nut-associated cacogeusia (or what the online public has termed "pine mouth") during this time. Most online contributors note a similar cacogeusia 1-3 days following pine nut ingestion lasting for up to 2 weeks. All cases seem self-limited. Patients occasionally describe abdominal cramping and nausea after eating the nuts. Raw, cooked, and processed nuts (in pesto, for example) are implicated. While there appears to be an association between pine nut ingestion and cacogeusia, little is known about this condition, nor can any specific mechanism of specific cause be identified. It is not known if a specific species of pine nut can be implicated. "Pine mouth" appears to be an emerging problem.
我们报告一例在食用松子后出现恶味，具体为金属味（一种感觉到的金属味或苦味）的病例。一名36岁男性在食用10 - 15颗烤松子（松属）一天后出现恶味。症状在接触后第2天最为严重，未经治疗在5天内逐渐改善。无其他症状，体格检查未发现异常。所有症状均无后遗症地消失。我们同时报告了2009年第一季度在线报道的与松子相关的恶味病例有所增加，以及在此期间与松子相关恶味（或网络公众所称的“松口症”）相关的在线搜索显著增加。大多数在线投稿者指出，食用松子后1 - 3天会出现类似的恶味，持续长达2周。所有病例似乎都是自限性的。患者偶尔会描述食用松子后出现腹部绞痛和恶心。生的、煮熟的以及加工过的松子（例如用于制作香蒜酱）都与此有关。虽然食用松子与恶味之间似乎存在关联，但对此病症了解甚少，也无法确定任何具体病因的特定机制。尚不清楚是否可以归咎于特定种类的松子。“松口症”似乎是一个新出现的问题。
