“…The clinical characteristics of primary sacral benign tumors were distinct from the one of spinal benign tumors. Some rare histologic types should be considered when the differential diagnosis [19][20][21][22][23][24][25]. It has been reported that hemangioma was the most frequent benign primary spine tumor in one hospital of China, which was different from the region of sacrum and our database showed giant cell tumor was the most common histological type at the sacrum [1].…”

Background: Sacral tumors and tumor-like lesions are a rare group of lesions that can affect children and adults of all ages. Little is known about clinical characteristics of age, gender, histologic type and anatomic site in China.Methods: 1385 patients with sacral tumors and tumor-like lesions, which had the clinical record at our bone tumor center from January 2000 to November 2018 were analyzed. The metastatic cancers were not included in the present study.Results: 51.7% (716 cases) were malignant and 48.3 % (669 cases) were benign tumors or tumor-like lesions. Of malignant tumors, chordoma was the most common malignant tumor (316 cases, 22.8% of all tumors), followed by chondrosarcoma, myeloma and other histologic types. The most common histological type of benign tumors was giant cell tumor accounting for 14.8% (205 cases) of all tumors, followed by neurofibroma, schwannoma and other types. The most common age group affected by malignant bone tumors was the 51- to 60-year-old group, followed by the 41- to 50-year-old group. The most commonly affected age group for benign tumors and tumor-like lesions was the 31- to 50-year-old group, followed by the 21- to 30-year old group. Furthermore, the following histologic types had the gender predilection. Chordoma, chondrosarcoma, myeloma and osteosarcoma affected more frequently males than females. Malignant peripheral nerve sheath tumor, lymphoma, giant cell tumor, neurofibroma, tuberculosis, teratoma and epidermoid cyst more frequently affected females than males.Conclusions: The large cohort of sacral tumors and tumor-like lesions in our database may reveal their clinical characteristics of age, gender, histologic type and anatomic site in China and features of sacral tumors and tumor-like lesions is fairly distinct from the mobile spine and extremities.

“…Neither of the three conditions' own etiology is not clear. The cause of epidermoid cysts is believed to be the introduction of ectoderm cells arising in early fetal life between 3 and 5 weeks [12]. In 2017, Dai et al reported a series cases of familial lumbar scheuermann disease with idiopathic scoliosis in China, which might indicate the genetic etiology of Scheuermann disease with IS.…”

Background and importance: Scheuermann’s disease (SD), intradural-extramedullary epidermoid cysts and idiopathic scoliosis (IS) are all rare conditions. The co-occurrence of the three condition on one case has not been reported in literature before. We describe an extremely rare case of SD co-occurrence with IS and intradural-extramedullary epidermoid cyst, which is the first in the literature. Clinical presentation: A 13-year old boy and his parents presented at Honghui Hospital complaining of progressive hyperkyphosis for 5 years and back pain for 2 months. Thorough medical examination and radiology confirmed the diagnosis of SD kyphosis, IS, and intradural-extramedullary epidermoid cyst. Medical panel with spine surgeons, oncologists, neurosurgeons, histopathologists and radiologists were consulted. Tumor excise, kyphosis recorrection and spine reconstruction surgery was conducted. Postoperative histological examination detected desquamation of keratin from the epithelial lining and stratified squamous epithelium without skin adnexa. The boy was ambulant 2 days postoperative with walking aids. Conclusion: This is the first case report of Scheuermann’s disease (SD) co-occurrence with idiopathic scoliosis (IS) and intradural-extramedullary epidermoid cyst. The co-occurrence of intradural epidermoid cyst, SD and IS might not be a coincidence, indicating a kind of genetic etiology need to be illuminated.
