Primary rectal teratomas are rare and only few cases have been reported in the literature worldwide. These usually occur in females. These are usually cystic but very rarely solid variants may occur. We present a case of a solid intra-rectal dermoid arising primarily in rectum from postero-lateral wall. Excision biopsy was done per rectally. Histology revealed the presence of squamous epithelium, fat cells, hair follicles, cartilaginous material and columnar lining of glandular structures suggestive of mature teratoma. It is usually benign but may become malignant, therefore complete resection is advised.
原发性直肠畸胎瘤很少见,全世界文献中仅报道了少数几例。这些通常发生在女性身上。它们通常是囊性的,但很少有实性变异。我们报告了一例源自直肠后外侧壁的原发性直肠内实性皮样瘤。经直肠进行了切除活检。组织学显示存在鳞状上皮、脂肪细胞、毛囊、软骨物质和柱状腺体结构,提示为成熟的畸胎瘤。它通常是良性的,但也可能恶变,因此建议完全切除。
