A 36-year-old female kitchenworker twice developed eczematous lesions corresponding exactly to the area around her neck where she had worn a wooden necklace. Contact dermatitis lasted longer than 1 week. The necklace consisted of 42 brown wooden beads and 63 other wooden parts, 0.5 to 3 cm diameter. Most parts could be identified as Cocobolo wood, Brazilian and East Indian rosewood, and teak. Patch tests with the pure constituents gave +3-reactions to three dalbergions and obtusaquinone, which are known to be the sensitizers of Cocobolo and the above-mentioned rosewoods. Because of these test results, the identification of the species by eye examination could be corroborated. Further detailed questioning revealed that the patient had played a recorder, probably made from Cocobolo (Dalbergia retusa), when a child, to which she unknowingly became allergic.
一名36岁的女性厨房工作人员颈部周围佩戴木质项链的部位两次出现了与项链形状完全相符的湿疹样皮损。接触性皮炎持续时间超过1周。这条项链由42颗棕色木珠和63个其他木质部件组成，直径为0.5至3厘米。大多数部件可鉴定为黄檀木、巴西玫瑰木和东印度玫瑰木以及柚木。对纯成分进行的斑贴试验对三种黄檀醌和钝叶醌产生了+++反应，已知这两种物质是黄檀木和上述玫瑰木的致敏原。基于这些检测结果，通过肉眼检查对木材种类的鉴定得到了证实。进一步详细询问发现，患者小时候曾吹奏过一支可能由黄檀木（Dalbergia retusa）制成的竖笛，她在不知不觉中对其产生了过敏反应。
