Intratendinous epidermal cysts are extremely rare soft-tissue lesions. Apart from traumatic occasions which are usually painful, in asymptomatic cases, they can be easily overlooked. The purpose of our study was to report the formation of an intratendinous epidermoid cyst after traumatic penetration and irritation of a wooden foreign body.
A 79-year-old man proceeded in the emergency department, with a skin cut in the dorsal side of the right hand from a sharp wooden segment. After surgical lavage and investigation for soft-tissue damages or subcutaneous foreign bodies, skin closure was performed. Ten months after trauma, the patient came again with persistent pain and limitation in range of motion of the ring finger. Ultrasonography demonstrated an intratendinous foreign body surrounded by the cystic lesion. Both the identified wooden fragment and the cyst, which were histopathologically verified as an epidermoid cyst, were removed.
Clinicians should be aware that a tendon injury, along with chronic irritation from a foreign body, might result in the formation of an intratendinous epidermoid cyst.
肌腱内表皮样囊肿是极其罕见的软组织病变。除了通常伴有疼痛的创伤情况外，在无症状的病例中，它们很容易被忽视。我们研究的目的是报告外伤性木质异物穿透和刺激后肌腱内表皮样囊肿的形成。
一名79岁男性因右手背被尖锐木片割伤而前往急诊科。在进行手术冲洗并检查软组织损伤或皮下异物后，进行了伤口缝合。创伤后十个月，患者因持续性疼痛和无名指活动范围受限再次前来就诊。超声检查显示肌腱内有异物，周围有囊性病变。已识别的木片和经组织病理学证实为表皮样囊肿的囊肿均被切除。
临床医生应意识到，肌腱损伤以及异物的慢性刺激可能导致肌腱内表皮样囊肿的形成。
