UNASSIGNED: Seven-year-old monozygotic twins presented to our department with a palpable, painless, and solid mass in the subcutaneous tissue of the right upper limb. A 1.5-cm diameter nodule was seen on the anterolateral aspect of the right upper extremity of the twins. The node was irregular in shape, and upon palpation, the patients reported no noticeable tenderness. Following the administration of local anesthesia, the twins underwent surgical procedure to excise the solid mass. Finally, they were diagnosed with pilomatricoma based on the clinical and histopathological features. Complete surgical resection followed by primary closure was performed. During a follow-up period of three years, there has been no recurrence observed in the twins.
UNASSIGNED: We reported a case of monozygotic twins with pilomatricoma in the same location on the skin of the right upper arm. Our findings underscore the requirement of considering genetic factors in the diagnosis and treatment of the rare conditions.
■7岁的同卵双胞胎被送到我们部门,无痛,和右上肢皮下组织中的实性肿块。在双胞胎右上肢的前外侧发现了一个直径1.5厘米的结节。节点形状不规则,在触诊时,患者报告没有明显的压痛。局部麻醉后,这对双胞胎接受了手术切除固体块。最后,根据临床和组织病理学特征,他们被诊断为毛囊瘤。进行完整的手术切除,然后进行初次闭合。在三年的随访期间,这对双胞胎没有复发。
■我们报道了一例在右上臂皮肤上相同位置的单卵双生子患有毛囊瘤。我们的发现强调了在罕见疾病的诊断和治疗中考虑遗传因素的要求。
