Abstract：
UNASSIGNED: Retention hyperkeratosis (RHK) is benign and commonly seen skin condition in dermatology clinics. Hyperkeratosis refers to the increased thickness of the outermost layer of skin stratum corneum. RHK occurs when there is abnormality of routine desquamation that can be associated with poor hygiene. There are various types of hyperkeratosis, and could be divided according to their etiology. Although RHK is commonly recognized by dermatologists it is rarely reported. To the best of our knowledge, this is the first reported case of RHK over surgical scar.
UNASSIGNED: A 63-year-old male presented to our dermatology clinic with severe RHK over a midline sternotomy scar post-coronary artery bypass grafting (post-CABG) in which he developed over the past 8 years. Our patient\'s history was significant in avoiding touching the surgical area as he feared disturbing the healing process of his surgical wound We discussed in details as further examination and investigations took a place on clinic-base during his management.
UNASSIGNED: Since RHK is associated with poor hygiene as we have seen in our patient\'s case, it could be prevented by providing the patient instructions regarding his wound care and general hygiene postoperatively and management of hyperkeratosis differs depending on type, severity, and chronicity. Our case represents a rare extreme manifestation related to the fear of our patient cleaning surgical wounds.

摘要：
■保留性角化过度（RHK）是良性的，在皮肤科诊所中常见的皮肤状况。角化过度是指皮肤角质层最外层的厚度增加。RHK发生在常规脱屑异常时，可能与不良卫生状况有关。角化过度有各种类型,并可根据其病因进行划分。尽管RHK通常被皮肤科医生认可，但很少有报道。据我们所知,这是首例报告的RHK手术瘢痕病例.
一名63岁的男性因冠状动脉旁路移植术后（CABG后）中线胸骨切开性瘢痕出现严重RHK，他在过去8年中发展起来。我们的患者的病史对于避免接触手术区域具有重要意义，因为他担心会干扰手术伤口的愈合过程。我们详细讨论了进一步的检查和调查在他的治疗期间在临床基础上占有一席之地。
■由于RHK与我们在患者病例中看到的不良卫生状况有关，可以通过向患者提供有关术后伤口护理和一般卫生的说明来预防，并且角化过度的管理因类型而异，严重程度,和慢性。我们的案例代表了一种罕见的极端表现，与我们的患者清洁手术伤口的恐惧有关。
