“…Metastatic tumors (12.8 %) were third in their series with recognized primary tumors originating from lung, colon and breast cancers. Other less common tumors include tumors of the skin appendages differentiated from follicular (2.3 %), sebaceous (4.3), or eccrine (3.5 %), and tumors of the soft tissue including angiosarcoma (6.8 %), dermatofibrosarcoma protuberans (2.8 %), and leimyosarcoma (2.0 %) [15].…”

Solitary fibrous tumors are an uncommon slow growing benign neoplasm originally described as a pleural neoplasm but can also be found in the lung, mediastinum, peritoneum, or any other sites including the head and neck. Case ReportA 37 year old female presented to the Oral and Maxillofacial Surgery clinic complaining of a bump on her posterior scalp. She was referred to our clinic by general surgery for evaluation and removal of this lesion. She states that the lesion had slowly begun to increase in size approximately 2 years ago, but was first noticed approximately 4 years ago. She stated that the lesion was very uncomfortable for her and hurt at times when sleeping. On clinical examination, there was a well-circumscribed mass at the right occipital quadrant. The lesion was approximately 5 9 6 cm in size. It was soft, not fluctuant, with a sessile base and mildly tender to palpation. No overlying erythema or ulceration was noted.It was difficult to ascertain the mobility of the lesion due to the location in the posterior occipital region and the thickness of the scalp tissue but appeared to be mobile. No neurological deficits were noted. A Computed Tomography (CT) scan was performed, revealing a well circumscribed 65 mm 9 30 mm 9 60 mm right parietal soft tissue mass of heterogeneous densities which was contiguous with the calvarium over 50 mm without bony erosion or remodeling and sharply defined from adjacent soft tissues (Fig. 1). After the risks, benefits, and alternatives were discussed with the patient, informed consent of excisional biopsy was signed. The patient was then prepped and draped in the standard sterile fashion. An incision was made using a #15 blade taking an elliptical portion of tissue overlying the lesion. After initial dissection, it was noted that the lesion

“…Treatment regimens commonly include actinomycin D, adriamycin, vincristine, and cyclophosphamide and methotrexate. Response rates to chemotherapy range between 30-40% and less than 50% are disease free at 5 years after diagnosis of metastasis [8]. Although the patient is tumourfree at 6 month follow-up further follow-up is mandatory.…”

Hemangiopericytoma is rare tumor originating from the pericytes, the contractile cells that surround capillaries. This tumor arises from pericapillary cells or pericytes of Zimmerman and can occur anywhere where capillaries are found. However hemangiopericytoma develops mainly in the lower extremities, retroperitoneum or pelvis. The recommended treatment for a hemangiopericytoma is wide excision. Since many benign and malignant diseases occur in the area surrounding the anus, recognizing the presence of this malignant tumor in the presacral space is important in order to avoid inappropriate surgery such as piecemeal excision. We describe a rare case of a hemangiopericytoma in the presacral space. With posterior approach the tumour was completely removed. Pathological examination including immunohistological stains was consistent with a hemangiopericytoma.

“…En general, el pronóstico es bueno cuando se obtiene resección completa en ausencia de metástasis, con sobrevida a los 5 y 10 años de 80% y 70% respectivamente. El seguimiento a largo plazo es fundamental; en un 44% las recurrencias y metástasis aparecen después de los tres años del diagnóstico 5,14,15 .…”

Hemangiopericytoma. A report of 3 cases and a literature review Introduction: The hemangiopericytoma (HPC) is a rare vascular tumor that can be potentially malignant. It can be found in any part of the body but usually in the lower extremities or the retroperitoneum. Because its potential malign nature, it's necessary to perform oncological resections when are operating on. Methods: Three cases are presented. Results: One of them was located at the sacrococcigeal space, being the second reported case in the international literature. The other cases were in cervical and adrenal localization.
