A ten-month-old girl presented to our clinic with a progressively enlarging congenital mass at the midline suprasternal location. Histopathologic examination revealed a benign cyst with stratified squamous keratinized epithelium with numerous eccrine glands in the sinus wall. The diagnosis was compatible with dermoid cyst. Dermoid cysts of the trunk are rare lesions, but a midline location is characteristic for these congenital masses. A dermoid cyst should be high on the list of differential diagnoses given a unilocular midline cyst in a neonate.
一名10个月大的女童因胸骨上缘中线处先天性肿块逐渐增大前来我院就诊。组织病理学检查显示为良性囊肿，囊壁为分层鳞状角化上皮，伴有大量小汗腺。诊断为皮样囊肿。躯干皮样囊肿是罕见病变，但中线部位是这些先天性肿块的特征。鉴于新生儿出现单房性中线囊肿，皮样囊肿应列在鉴别诊断清单的前列。
