A 15-year-old Japanese girl had an asymptomatic nodule on the right thigh of seven months' duration. The clinical appearance was similar to that of a bulla. There was a history of blunt trauma from dog scratch to the skin over the tumor shortly before tumor growth. Histopathological findings were consistent with pilomatricoma. In the overlying dermis, the collagen bundles were compressed to the tissue surrounding the tumor and the large space was seen. Around the tumor, some dilated endothelium-lined vascular channels were found, which were identified as lymphatic vessels.
一名15岁日本女孩右大腿出现一个无症状结节，持续7个月。临床表现与大疱相似。在肿瘤生长前不久，肿瘤上方皮肤有被狗抓伤的钝性外伤史。组织病理学检查结果符合毛母质瘤。在上覆真皮层，胶原束被挤压至肿瘤周围组织，可见大的间隙。在肿瘤周围，发现一些内皮细胞衬里的扩张血管通道，被确定为淋巴管。
