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.

Well Differentiated

AbstractBackground:Liposarcomas rarely occur in the parapharyngeal space and only a few case reports exist. For curative therapy of liposarcoma, surgical excision remains the dominant modality. Although a wide surgical margin is important to prevent local recurrence, wide excision is often difficult in the head and neck region.Case report:We report a case of a 19-year-old female with a well-differentiated liposarcoma arising in the parapharyngeal space. We removed the tumour surgically utilising a cervical–parotid approach. The histological diagnosis was well-differentiated sclerosing liposarcoma. There is no recurrence after five years and nine months of follow up.Conclusion:The patient's age and the tumour site made it difficult for us to make a quantitative diagnosis before the operation. Well-differentiated liposarcoma rarely develop distant metastasis, but often recur locally. The benefit of adjuvant radiotherapy for well-differentiated liposarcoma is still not clear and careful and long-term follow up is necessary.

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.

Background. Osteoblastoma is a rare benign tumor. This tumor is characterized by osteoid and bone formation with the presence of numerous osteoblasts. The lesion is more frequently seen in long bones and rarely involves maxilla and mandible. Due to its clinical and histological similarity with other bone tumors such as osteoid osteoma and fibro-osseous lesions, osteoblastoma presents a diagnostic dilemma.Case Report. Very few cases of osteoblastomas involving maxillofacial region have been reported in the literature. This case report involves osteoblastoma involving right maxilla in an 18-year-old male patient. Following detailed clinical examination, radiological interpretation, and histopathological diagnosis, surgical excision was performed. The patient was followed up for a period of 3 years and was disease free.Summary and Conclusion. Benign osteoblastoma involving jaw bones is a rare tumor. There is a close resemblance of this tumor with other lesions such as fibro-osseous lesions and odontogenic tumors and thus faces a diagnostic challenge. Surgical excision with a long-term follow-up gives good prognosis to this lesion—Benign Osteoblastoma.

AbstractThe present study is a case report of vulvar lipoma. The vulva is a rare site for the development of lipomas, and the aim of the study is to determine if the current imaging modalities can diagnose lipomas correctly. A 43-year-old patient presented with a painless, slowly progressive, oval, mobile and non-tender right vulvar mass compressing the vagina and totally covering the introitus. Both the ultrasonography and magnetic resonance imaging (MRI) exams suggested the diagnosis of lipoma. Surgical excision was performed, and the histopathological examination of the mass confirmed a lipoma.

ABSTRACTHuman coenurosis is a rare zoonotic disease caused by the larvae of Tinea multiceps seen in sheep-rearing countries. We report the case of a 63-year-old male who was referred to our hospital with a working diagnosis of skull base chondrosarcoma. Histopathological examination after surgical excision revealed characteristic feature of coenurus with multiple scolices invaginating from the outer cuticular layer. Coenuri are often mistaken for giant cysticercal cysts and hydatid cysts. Despite its wide prevalence in cattle, only two cases of human coenurosis are reported from India till date. We report the third case from India.

Neurenteric cysts account for 0.7-1.3% of spinal axis tumors. These uncommon lesions results from the inappropriate partitioning of the embryonic notochordal plate and presumptive endoderm during the third week of human development. Heterotopic nests of epithelium reminiscent of gastrointestinal and respiratory tissue lead to eventual formation of compressive cystic lesions of the pediatric and adult spine. We report a 40-year-old male  presenting with slow-progressive myelopathic manifestation and ovoid non-enhancing cysticintradural extramedullary lesion at C7 level on MRI, mimicking intraspinal arachnoid cyst, who underwent successful surgical excision. The histopathological examination prove it to be neurenteric cyst.

Ossifying Fibromyxoid Tumor

A 13-year-old boy who complained rapid swelling on the left side of mandible is presented. Histopathological examination revealed ossifying fibromyxoid tumor (OFMT). OFMT is a rare soft-tissue neoplasm that occurs usually in the subcutaneous tissue of the extremities. Head and neck involvement is relatively rare. In this case, we present the diagnosis, surgical treatment and long-term follow-up of an OFMT due to its unusual site of occurrence. The precise clinical behavior of atypical and malignant types of OFMTs is still unclear. Thus, histopathology report is important, leading surgeon to decide how often and how long to follow-up patient with OFMT.

Extraskeletal Myxoid Chondrosarcoma (EMC) is a rare malignant soft tissue sarcoma with uncertain differentiation, most often seen in males. The incidence is 3% of all soft tissue tumours with limited literature available on its cytological features. EMC may arise from lower extremities, upper extremities, retroperitoneum, pelvis, and buttocks. This case report was an effort to understand the role of Fine Needle Aspiration Cytology (FNAC), histopathology and immunochemistry in the diagnosis of EMC. Authors hereby report a case of a 70-year-old male patient with slow-growing soft tissue swelling on the back just behind the right shoulder who was referred for FNAC. Patient complete history and clinical findings were recorded. Radiological images were suggestive of malignant soft tissue neoplasm with no involvement of underlining bone. FNAC reveled tumour cells which appeared monotonous and they were seen in a myxoid stroma background. Subsequently, the excised lesion was sent for histopathological examination and the report revealed the presence of abundant chondromyxoid matrix material within which were found numerous elongated spindly shaped cells. These cells had moderately pleomorphic elongated nuclei with focal solid fibrocollagenous areas along intersecting fascicles of the moderately pleomorphic spindly cell. Few of these cells had multilobulated bizarre nuclei with nuclear inclusions. Immunohistochemical stains showed diffuse positivity for S-100, vimentin, and focally positive for Epithelial Membrane Antigen (EMA). The FNAC, histopathology and immunohistochemical features confirm the diagnosis of EMC on right shoulder. It’s a rare tumour whose diagnosis is made depending on history, clinical location, growth pattern, histopathology, and immunohistochemistry.

Cutaneous Leiomyomas

<p class="abstract">Cutaneous leiomyomas are benign tumors that can be exquisitely painful. Comprise three distinct types such as piloleimyoma, angioleiomyoma, and genital leiomyoma. Piloleiomyomas, derived from arrector pili muscle, are solitary or multiple firm papulonodules located mostly on the extremities and trunk; genital leiomyomas, derived from dartoic, vulvar, or mammary smooth muscle, are solitary or papulonodules located on the scrotum, vulva, or nipple; and angioleiomyomas, include solid, cavernous, or venous subtypes, are derived from the tunica media of small arteries and veins and typically present on the extremities. Excisional biopsy is required for diagnosing all cutaneous leiomyomas Histology shows interlacing fibers of spindle cells with moderate amounts of eosinophilic cytoplasm and a blunt-ended, elongated nucleus with perinuclear halos. Surgical excision is curative for cutaneous leiomyomas, with other management options including medical or destructive therapy. A 36-year-old male patient presented with a 13 years history of painful, multiple lesions over the back. Based on the histopathological examination, imaging, and past medical records, a diagnosis of familial leiomyoma was made. His brother had similar disease. The patient was started on tab gabapentin 300mg at night. Patient advised for carbon dioxide laser excision. The present case report has been reported for its interesting clinical presentations and rarity.</p>
