Abstract Spermatocytic tumor is a rare testicular tumor, which is originated from gonocytes. It is characterized by the histological feature of tripartite which is composed of large, medium, and lymphocyte-like small cells. It is well-known that spematocytic tumor is benign, thus a good prognosis is expected after simple resection. Metastatic spermatocytic tumor is extremely rare and usually accompanied by histological variants including sarcomatous changes and anaplastic variants. In this case, however, we report a canine metastatic spermatocytic tumor without prominent sarcomatous changes and anaplastic variants. The mass was composed of three kinds of cells including large, medium, and small cells with high pleomorphism. The neoplastic cells had an indistinct cytoplasmic border and mitotic figures were frequently observed. The primary spermatocytic tumor metastasized to the abdominal organs one month after the resection, and the dog died 13 months after the surgery. Thus, careful follow-up is recommended after surgical resection of canine spermatocytic tumor even though metastasis in spermatocytic tumors is rare.

Different cellular constituents of the central nervous system occurring in encephaloceles or neuroglial heterotopias (NGHs) have been reported, but the ependymal morphology has rarely been described in the previous literature, let alone the related histological images. To determine the ependymal morphology in encephaloceles or NGHs, we report a rare case of encephalocele with numerous ependymal components. Radiological examination showed that a 6.2 × 3.1 cm nasal dorsum mass-forming encephalocele in a 24-year-old woman, who had an intracranial connection through a frontal bone defect. This patient underwent a resection of the encephalocele under nasal endoscopy and a reconstruction of the cranial base. The patient had a good prognosis with no postoperative complications during follow-up. Microscopically, the ependymal components entrapped in a collagenized background showed numerous slit-like spaces lined by columnar cells with abundant palely eosinophilic cytoplasm and apical surface microvilli. With immunohistochemistry, in addition to the expression of EMA along with the slit-like spaces, GFAP and S100 were diffusely expressed in the slit-like spaces. In conclusion, the ependymal component in either encephaloceles or NGHs may present slit-like spaces arranged in an anastomosing pattern. The unusual morphology of ependyma continues to be underrecognized by pathologists and is easily misdiagnosed; therefore, an awareness of the morphological change in ependyma is necessary.

Rare Case Report

Abstract Spinal Teratomas are rare tumor and cervical intramedullary location in infancy still rarer. Only eleven cases of cervical intramedullary teratoma in pediatric patients is reported in available literature (1, ll). We are reporting a case of an infant presenting with cervical mature teratoma with associated dysraphism, adding the next in this rare case series. Arising as a result of dysembryogenesis, these lesions by virtue of their content are difficult to diagnose preoperatively. Heterogeneous intensities on MRI produced by intralesional lipomatous and osseous elements are helpful but rarely enough to diagnose the tumor. Histology is confirmatory. Mature teratomas generally have good prognosis and a timely intervention can prevent further neurological deterioration. However a strict clinical and radiological follow up is recommended.

AbstractEctopic recurrence of craniopharyngiomas after surgical resection of primary lesion is extremely rare. In this article, the authors describe a case of a 12-year-old girl with ectopic recurrence of craniopharyngioma in an extra-axial location in the right frontal region, after an attempt to completely resect the lesion originally located in the sellar region. The patient was investigated radiologically, hormonally, and histopathologic confirmation was sought. During surgery, it is important to take extra care in removing the primary lesion in toto. In case of cystic tumors, it is very important to aspirate cystic fluid completely, before resecting the capsule to avoid rupture or spillage. Long-term clinical and radiologic follow-up is suggested as ectopic recurrence may occur at a very late stage.

Laryngeal Involvement

This study was performed to investigate the clinical manifestations, treatment methods, and prognosis of Rosai-Dorfman disease (RDD) with laryngeal involvement. Five clinical cases of RDD with laryngeal involvement diagnosed between 1986 and 2015 were retrospectively analyzed. The laryngeal lesions of these 5 patients mostly involved the glottis and subglottis, with the main symptoms being a hoarse voice and airway obstruction. In addition, the patients mostly exhibited a unilateral or asymmetric onset that was manifested by a laryngeal submucosal nodular mass. The patients were subjected to a regimen of hormone treatment combined with surgical resection. The median follow-up duration was 101 months (8–384 months). One case was lost, and the remaining 4 subjects are alive with disease. The follow-up examinations revealed that 4 subjects had stable laryngeal conditions, whereas one showed minor progression. RDD with laryngeal involvement is clinically rare and differs considerably from classical RDD in age of onset, gender composition, and extranodal involvement. The regimen of hormone treatment combined with surgical resection can stabilize the patient’s general condition and laryngeal lesion. Tracheotomies are recommended for patients with dyspnea. After their conditions stabilize, decannulation can be successfully performed in most cases. This therapeutic regimen generally delivers a good prognosis.

Infantile Fibrosarcoma

Infantile fibrosarcoma is a rare type of soft tissue sarcoma seen in children usually less than 2years of age. Few cases of giant infantile fibrosarcoma have been reported in literature. We report a rare case of a giant multi-nodular infantile fibrosarcoma in the left anterolateral chest wall in a 7-year-old boy. The tumour was said to have been recurrent twice for about 6 years. At presentation patient was evaluated and was commenced on 6 cycles of neoadjuvant chemotherapy with vincristine, adriamycin and cyclophosphamide (VAC) regimen to alternate with Ifosfamide/Etoposide (IE) regimen with very good response. Thereafter, had a wide local excision of the tumour and then had 4 more cycles of adjuvant chemotherapy. His 6months follow up showed no evidence of tumour recurrence. Infantile fibrosarcoma is said to be chemo-sensitive tumour with very good response, though surgical excision is the main treatment of choice and overall it is said to have a good prognosis.

Background: Kimura's disease is a rheumatic immune disease and head and neck lymph nodes are often involved. A mass occurring in the nasal forehead is rare. Good prognosis after surgical resection by glucocorticoid therapy is more rare.Case Summary: We report the rare case of a nasal forehead mass in a 45-year-old male patient with Kimura's disease. The patient underwent resection of the mass in October 2018 in a local hospital and the postoperative pathology was unclear. He then underwent a second resection in our department in December 2019 mainly because growth of the mass was affecting his appearance. Postoperative pathology confirmed that the patient had Kimura's disease, and he accepted systemic treatment with prednisone. We followed the patient for 10 months after surgery. He is now recovering well and continues to be closely monitored during follow-up.Conclusion: It is rare that the painless mass in the nasal forehead is diagnosed as a Kimura's disease.After completely resection of the mass and systemic treatment with prednisone, the patient had a good outcome. We provide experience for the treatment of Kimura's disease in nasal forehead.

Abstract Background Erdheim-Chester disease (ECD) is a rare, idiopathic, systemic non-Langerhans cell histiocytosis involving long bone and visceral organs. Central nervous system (CNS) involvement is uncommon and most cases develop as a part of systemic disease. We present a rare case of variant ECD as an isolated intramedullary tumor. Case presentation A 75-year-old female patient with a medical history of diabetes and hypertension presented with sudden-onset flaccid paraparesis for 1 day. Neurological examination revealed grade 2–3 weakness in both legs, decreased deep tendon reflex, loss of anal tone, and numbness below T4. Leg weakness deteriorated to G1 before surgery. Preoperative magnetic resonance imaging (MRI) and 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) showed an intramedullary mass lesion at T2-T4 with no systemic lesion, which was heterogeneous enhancement pattern with cord swelling and edema from C7 to T6. Gross total removal was achieved for the white-gray-colored and soft-natured intramedullary mass lesion with an ill-defined boundary. Histological finding revealed benign histiocytic proliferation with foamy histiocytes and uniform nuclei. We concluded it as an isolated intramedullary ECD. The patient showed self-standing and walkable at 18-month with no evidence of recurrence and new lesion on spine MRI and whole-body FDG-PET/CT until sudden occurrence of unknown originated thoracic cord infarction. Conclusions We experienced an extremely rare case of isolated intramedullary ECD, which was controlled by surgical resection with no adjuvant therapy. Histological examination is the most important for final diagnosis, and careful serial follow-up after surgical resection is required to identify the recurrence and progression to systemic disease.
