ABSTRACT

Introducción: El hemangiopericitoma es un raro tumor mesenquimal (vascularizado y potencialmente maligno) derivado de los pericitos, que puede aparecer en cualquier parte del cuerpo; sin embargo, en el cuello se describen casos aislados. La resección quirúrgica completa constituye la piedra angular del tratamiento. Objetivo: Presentar un caso de un hemangiopericitoma en el cuello, como un caso inusual, con potencial maligno desconocido, diagnóstico y tratamiento oportuno. Presentación de caso: Paciente de sexo masculino, de 39 años de edad, sin antecedentes de enfermedad conocidos, con una masa perceptible a nivel V del cuello derecho. Estudios de imagen muestran un tumor vascularizado de aproximadamente 6 x 7 x 6 cm, entre los músculos escalenos, que fue originado en la arteria cervical profunda. Se confirmó mediante biopsia incisional el hemangiopericitoma, el cual fue tratado mediante resección tumoral completa y radioterapia adyuvante. Actualmente el paciente no tiene actividad tumoral después de su tratamiento inicial. Conclusiones: El hemangiopericitoma en el cuello es raro, el diagnóstico constituye un reto clínico e histológico, ya que, al ser poco común, su potencial maligno resulta desconocido. Aquellos tumores que tienen bajo grado de malignidad pueden ser controlados, de acuerdo a su localización y tamaño, mediante resección completa; mientras que los tumores de alto grado pueden recurrir y dar origen a metástasis. Nuestro paciente tuvo características histopatológicas con invasión capsular, lo que trajo como consecuencia un incremento del riesgo de recurrencia local. Por ese motivo, se decidió aplicar tratamiento adyuvante con radioterapia. El paciente se mantiene sin recurrencia tumoral local y a distancia después de 9 años de vigilancia médica(AU)


Introduction: Hemangiopericytoma is a rare mesenchymal tumor (vascularized and potentially malignant) derived from pericytes. It can occur anywhere in the body; however, isolated cases are described in the neck. Complete surgical resection is the cornerstone of treatment. Objective: To present a case of hemangiopericytoma in the neck, as an unusual case, with unknown malignant potential, as well as its timely diagnosis and treatment. Case presentation: A 39-year-old male patient, with no known history of disease, had a noticeable mass at the V level of the right neck. Imaging studies showed a vascularized tumor of approximately 6 x 7 x 6 cm, between the scalene muscles, which originated in the deep cervical artery. Hemangiopericytoma was confirmed by incisional biopsy, as well as treated by complete tumor resection and with adjuvant radiotherapy. Currently, the patient has no tumor activity after his initial treatment. Conclusions: Hemangiopericytoma in the neck is rare. Its diagnosis is a clinical and histologic challenge because, being uncommon, its malignant potential is unknown. Those tumors with low-grade malignancy can be controlled, according to their location and size, by complete resection; while high-grade tumors may recur and give rise to metastases. Our patient had histopathologic features with capsular invasion, which resulted in an increased risk of local recurrence. For this reason, adjuvant treatment with radiotherapy was decided to be applied. The patient remains without local or distant tumor recurrence after 9 years of medical surveillance(AU)

ABSTRACT

Haemangiopericytoma is a rare soft tissue tumour characterised by tightly packed tumour cells situated around thin walled endothelial lined vascular channels, ranging from capillary sized vessels to large gaping sinusoidal spaces. The tumour cells are surrounded by reticulin and are negative for muscle, nerve and epithelial markers. The diagnosis of extra-pulmonary intra-thoracic, extra-pleural mediastinal mass is difficult. It constitutes only 6% of all primary tumours and cysts of the mediastinum. We report the rare occurrence of primary intra-thoracic, extra-pulmonary mediastinal haemangiopericytoma of mesenchymal origin with perivascular localisation. The patient underwent right postero-lateral thoracotomy and postoperatively received chemotherapy with adriamycin (60 mg/m2) on day 1 and ifosfamide (1.5 g/m2) on day 1 to 3. Thirtyseven months after the operation, the patient has been well with evidence of a single recurrence in the left lower lobe.
