Ameloblastic fibrosarcoma is an uncommon odontogenic tumor composed of a benign epithelial component and a malignant ectomesenchymal component most frequently seen in the third and fourth decades of life. It mainly presents as a painful maxillary or mandibular swelling. Radiographs show a radiolucent mass with ill-defined borders. Radical surgical excision and long-term follow-up are the suggested treatment. We report the case of a 22-year-old female with a 2-month history of an asymptomatic swelling in her left mandible. Examination revealed an exophytic growth measuring3×3 cm extending from the mandibular left first premolar to the second molar. The patient underwent a left hemimandibular resection. Histopathological examination revealed a biphasic tumor composed of inconspicuous islands of benign odontogenic epithelium and an abundant malignant mesenchymal component with marked cellularity, nuclear pleomorphism, hyperchromatism, and moderate mitotic figures with clear margins; one year after the surgical procedure, the patient is clinically and radiologically disease-free.

Basaloid follicular hamartoma (BFH) is a normally benign, uncommon, malformative lesion involving the hair follicles, which usually poses challenges in the differential diagnosis with other benign and malignant tumours, especially basal cell carcinoma, due to significant clinical and morphological overlap. Here, we report the case of a 53-year-old male who presented with a mass in the upper left eyelid evolving for one year. The patient had a previous history of total colectomy and an abdominal desmoid tumour within the context of Familial Adenomatous Polyposis (FAP), with a documented germline mutation in the Adenomatous Polyposis Coli (APC) gene. The eyelid lesion was biopsied and the histological analysis of the three small tissue fragments received revealed fragments with cutaneous–conjunctival lining displaying a subepithelial proliferation of basaloid nests with peripheral palisading, compatible with primitive hair follicles. There were images of anastomosis between different basaloid nests, which had their connection to the epithelial lining preserved. The stroma had high cellularity and sometimes primitive mesenchymal papillae were evident. Pleomorphism was absent, mitotic figures were barely identified, and no necrosis was seen. The basaloid nests did not have epithelial–stromal retraction nor mucin deposits. A diagnosis of BFH was proposed, which was later confirmed after surgical excision of the whole eyelid lesion. No evidence of carcinoma was present. This case illustrates the main features of the rare benign eyelid BFH. The standard medical or surgical approach of these lesions remains to be firmly established. Nearly nine months after surgical excision our patient remains well without signs of disease recurrence.

We report a rare case of an extramedullary plasmacytoma (EMP) in the frontal sinus with an indolent clinical presentation. Although a history of trauma was absent, the initial diagnosis was a mucocele, based on the radiological findings. Upon surgical excision, the patient was found to have an EMP. EMP, a form of solitary plasmacytoma, has a significantly high rate of conversion to multiple myeloma. This mandates long-term follow-up, even after successful radiotherapy and/or resection. While radiation therapy is generally considered a first line treatment for EMP, surgical intervention may provide optimal treatment in complicated cases. This case presentation highlights the prognosis of patients diagnosed with EMP.

Ocular surface squamous neoplasia (OSSN) includes the dysplastic lesions involving the epithelium of conjunctiva and cornea with various clinical pictures. Histopathological examination of the excised tissue is the benchmark for diagnosis. Surgery, chemotherapy, immunotherapy are the various treatment modalities which in combination shows promising result. We present here a case of 83 years old female patient with history of fleshy mass covering the cornea and the patient was diagnosed clinically as ocular surface squamous neoplasia. Patient underwent surgical excision of the mass followed by cryotherapy. Histopathological examination revealed conjunctival intraepithelial neoplasia of grade 3. Six months after treatment the patient is completely tumor free with no recurrence.

<p class="abstract">Pleomorphic adenoma are common benign salivary gland tumours, which are found in majority in major salivary glands such as parotids and submandibular glands. However, Pleomorphic adenoma to originate from dorsum of the nose is a rare entity. In rare cases, it can be found in unusual sites such as upper aero digestive tracts, palate and lacrimal glands. Complete surgical resection is the treatment of choice. Though, the evolution to malignancy and recurrence is not usually encountered, still a long-term follow-up is recommended. Here, we report a 53 year old female , complained of swelling in the left side of dorsum of nose for 10 years with a feeling of heaviness over the left side of face and difficulty in vision on the side of swelling due to the enlarged size of the swelling which gave a feeling of vision disruption , also had a prior history of  incision and drainage 4 years ,done elsewhere. On clinical examination, nodular mass was palpated on left side dorsum of nose which was freely mobile, and Skin over the swelling had blackish pigmentation. Anterior rhinoscopy revealed no abnormalities. Complete surgical excision via a lateral rhinotomy incision was performed. Cytological and histological evaluation revealed the presence of pleomorphic adenoma. We observed a decent cosmetic outcome with no evidence of recurrence.</p>

Background: SPS is a disorder consisting of rigidity of axial muscles with painful spasms. More than 80 % of SPS patients have high titer antibodies against glutamic acid decarboxylase (GAD). The use of rituximab for the treatment of SPS is a recent therapeutical approach showing promising results. We present a case of SPS treated with rituximab, showing a good and safe response. Case: A 38-year-old female patient presented with a history of rigidity of abdominal and paravertebral muscles associated with painful spasms in lower back region, increased tonus, lumbar lordosis, frequent falls and severe functional limitation. The anti-GAD antibodies were positive in high titles. Electromyography showed continuous motor activity with normal morphology especially on paravertebral muscles. She had a partial response to baclofen and diazepam, but could not tolerate it because of somnolence, and started the treatment with rituximab. After one year, the baclofen was discontinued and the diazepam reduced. The axial stiffness and spasm frequency improved, including postural instability, without new episodes of falls. Discussion: Rituximab is a monoclonal antibody targeting the CD20 antigens on the surface of mature B lymphocytes. After binding to these antigens, it initiates a cascade of biochemical events leading to apoptosis. Its use has been approved for numerous diseases with promising results. The use of rituximab in the treatment of SPS is a recent approach and good results have been reported. Conclusion: Rituximab may be a promising option in SPS treatment. However, this is a preliminary paper showing partial results requiring long-term follow-up.

We present a rare case of multiple spinal perimedullary arteriovenous fistulae associated with the Parkes-Weber (PW) syndrome. A 31-year-old male known to have the PW syndrome involving the left leg since birth, presented with a 7-month-history of progressive myelopathy of the lower extremities and dysfunction of the bladder and bowel. Myelography demonstrated dilated intradural vessels. Angiography demonstrated two distinct single hole perimedullary arteriovenous fistulae near the conus at two different metameres. They were supplied by the left posterior spinal artery. The patient was treated by transarterial embolisation using polyvinyl alcohol particles, which resulted in venous side occlusion of the fistulae. After the treatment, the patient developed transient worsening of the spasticity of the lower extremities, and was treated by heparinization. After heparinization, the patient partially recovered from the pre-embolisation status of his myelopathy. The follow-up angiogram one year after the embolisation demonstrated persistent obliteration of both fistulae. At long-term follow-up, the patient can ambulate without assistance and work as a farmer.

Subdural osteomas are extremely rare benign neoplasms. Here, we report the case of a 35-year-old female patient with a right frontal and parietal subdural osteoma. The patient presented with a 2-year history of intermittent headache and fatigue. Computerized tomography (CT) scan showed a high-density lesion attached to the inner surface of the right frontal and parietal skull. Magnetic resonance imaging (MRI) demonstrated T1 hyperintensity and T2 hypointensity of the lesion. Intraoperatively, the hard mass was located in subdural space and attached to the dura mater. Histopathological examination revealed lamellated bony trabeculae lined by osteoblasts and the intertrabecular marrow spaces occupied by adipose tissue. The patient underwent neurosurgical resection and recovered without complication. Surgical excision is recommended to extract the symptomatic lesions with overlying dura mater.

Two cases of calcifying cystic odontogenic tumor (CCOT) of the dental follicle in an impacted third molar without clinical and radiological evidence are reported during routine histopathological examination. In both the cases left mandibular third molar was mesioangularly impacted with pericoronal radiolucency of less than 2.5 mm, which was not indicative of any pathology. As a routine protocol (which is not practiced widely) of our institution, dental follicles associated with extracted molars were sent for histopathological examination. Histopathological features were consistent with CCOT with pathognomonic ghost cell transformation of odontogenic epithelium. The patients were followed for one year with no recurrence. This paper emphasizes the importance of routine histopathological examination of dental follicles associated with asymptomatic impacted teeth without any clinical or radiographic evidence of follicular lesion.

Intracranial intravascular papillary endothelial hyperplasia (IPEH) is very rare, and to our knowledge long-term follow-up results have not been previously published. An 11-year-old boy presented with a 6-month history of progressive visual impairment in the right eye. Magnetic resonance imaging revealed a well-enhanced, large parasellar mass involving the cavernous sinus, right frontal skull base, and ethmoid and sphenoid sinuses. Frontotemporal craniotomy and subtotal resection were performed, and the diagnosis of IPEH was confirmed. The mass increased in size during the following 3 months. A second operation was performed via frontotemporal craniotomy combined with a transsphenoidal approach, and gross-total resection of the tumor was achieved. Adjuvant radiotherapy (5040 cGy) and chemotherapy with interferon were administered. The patient's visual symptoms improved, and there was no recurrence during a 13-year follow-up period. The results of this case indicate that intracranial IPEH can recur with subtotal resection; however, optimal resection with multimodal adjuvant treatment can control the disease for many years, if not permanently.

Introduction: Hemangiopericytoma is a mesenchymal tumour originating from pericytes surrounding the capillary vessels. The etiology of this tumour is still unknown. It may be located in any part of the human body. The most common sites are pelvis and lower limbs and less often it occurs in the head and neck. The characteristic signs of hemangiopericytoma are slow growth regardless of the malignancy level and high vascularity. Surgical excision of the tumour with additional radiotherapy is the treatment of choice. Case report: A symptom presentation and diagnostic-therapeutic process in a 71-year-old woman admitted to the Department of Otolaryngology of the Medical University of Warsaw due to increasing bilateral nasal obstruction and dysphagia is herein described. Diagnostic imaging showed highly vascularized tumour in the parapharyngeal space also obstructing the left side of the nasopharynx. After evaluation, tumour resection from the external approach was planned and performed, followed by an uncomplicated postoperative course. Histopathological examination revealed hemangiopericytoma. The patient was qualified for adjuvant radiotherapy. She stays under observation with no signs of recurrence since surgery. Conclusions: Hemangiopericytoma is a rare tumour with a wide variety of clinical presentations and a relapse-free survival that is difficult to predict. Long-lasting asymptomatic tumour growth results in late diagnosis. Imaging and primarily, histopathological examination are fundamental for the diagnostic process. The best outcome is observed after radical surgical treatment. In order to reduce the risk of recurrence, additional radiotherapy is advised. Local recurrence may appear years after finished treatment, therefore long-term follow-up is essential.
