ABSTRACT
A 54-year-old female patient presented with a left nasal obstruction. On physical examination a pink delimited mass in the left nostril was observed. A cranial computed tomography scan revealed an expansive mass in the upper anterior third of the left nasal fossa, partially obstructing it. Endoscopic resection of the mass was performed. Histopathology revealed an atypical mesenchymal proliferation formed by cells disposed in disorganized and interconnected long bundles. Tumor cells had abundant eosinophilic cytoplasm and an oval, vesicular and hyperchromatic nucleus. Frequent mitotic figures were observed, many of them atypical. Necrosis was not observed. Immunohistochemistry showed tumor cells to be positive for calponin, muscle specific actin, caldesmon and smooth muscle specific myosin. Ki-67 index proliferation was 30%. A diagnosis of leiomyosarcoma of the nasal fossa was established.

Paciente mujer de 54 años que acude a consulta por un cuadro de obstrucción nasal. En la exploración física se observa una lesión rosada, bien delimitada, en la fosa nasal izquierda. Se realiza TAC de macizo facial en la que se observa una masa expansiva a nivel del tercio anterosuperior de la fosa nasal izquierda. Se realiza resección endoscópica. Histológicamente se observa una proliferación mesenquimal atípica constituida por células que forman haces largos desorganizados y entrecruzados. Las células tumorales presentan un citoplasma amplio eosinófilo y núcleo ovalado, vesiculoso e hipercromático. Se aprecian frecuentes figuras mitóticas, muchas de ellas atípicas. No se observa necrosis. En el estudio inmunohistoquímico se evidenció inmunorreactividad de las células tumorales frente a calponina, actina muscular específica, caldesmón y miosina específica de músculo liso. El índice de proliferación frente a KI-67 fue de un 30%. Con todos estos hallazgos se estableció el diagnóstico de leiomiosarcoma de fosa nasal.(AU)

Spindle cell carcinoma of the nasal cavity is a rare variant of squamous cell carcinoma. We report a case of a 50 year-old male presenting with a polypoid mass in the left nasal cavity. Histologically, the tumor was biphasic, composed of non-keratinizing squamous nests and a sarcomatoid stroma with positivity for CKAE1-AE3. Metastatic ipsilateral lymph nodes were present and the patient underwent radical neck dissection, followed by adjuvant radiotherapy and cisplatin. Two years after diagnosis the patient is free of disease.

Los leiomiosarcomas de la cavidad nasal y senos paranasales son neoplasias malignas de baja frecuencia, localmente agresivas. Presentan una alta tendencia a la recurrencia de aproximadamente 55% en nariz y senos paranasales. Están conformados por células musculares lisas. Según diversos autores, aproximadamente el 50% de los pacientes mueren antes del primer año y la supervivencia a los 5 años es del 20%. Anteriormente se pensaba que no poseían potencial metastásico, sin embargo, en series actuales se ha visto que presentan un alto poder metastásico de hasta el 50%. Las metástasis se presentan de forma tardía. El tratamiento recomendado consiste en la resección radical del tumor primario con un amplio margen de tejido normal y la radioterapia es de uso controversial en el manejo.
Leiomyosarcoma of the nasal cavity and paranasal sinuses are malignant, low frequency, locally aggressive neoplasm. They present a high tendency to recurrence of approximately 55% in the nose and paranasal sinuses. They are made up of smooth muscle cells. According to different authors, approximately 50% of patients die before the first year and survival at 5 years is 20%. Previously it was thought that they did not possess metastatic potential, however in current series it has been seen that they have a high metastatic power of up to 50%. Metastases present late. The recommended treatment consists of radical resection of the primary tumor with a wide margin of normal tissue.

El carcinoma renal de células claras es el tipo histológico más frecuente. En el momento del diagnóstico, las metástasis están presentes en 25-30 por ciento de los pacientes aproximadamente. La peculiar tendencia de dicho carcinoma a metastizar en localizaciones poco usuales, hace de este proceso oncológico un tumor primario a tener en cuenta en el diagnóstico diferencial de las metástasis como primera manifestación de neoplasia. Se presenta un caso poco frecuente, con tumor en fosa nasal izquierda y epistaxis recidivante, secundaria a metástasis de carcinoma renal como primer síntoma(AU)
The renal carcinoma of clear cells is the most frequent histological type. Metastasis is present in approximately 25-30 percent of the patients in the diagnosis. The peculiar tendency of this carcinoma to make metastasis in not very usual areas, makes of this oncological process a primary tumour to keep in mind in the differential diagnosis of metastases as the first neoplasia manifestation. A not very frequent case is presented, with tumour in the left nasal cavity and recurrent epistaxis, secondary to metastasis of renal carcinoma as first symptom(AU)

ABSTRACT
Supernumerary nostril is a very rare congenital anomaly, which includes additional nostril with or without accessory cartilage. In the present case of the left supernumerary nostril, a small cavity of around 3 mm diameter and accessory lower lateral cartilage were present. The cavity was lined with mucous membrane and filled with mucoid discharge .Nasal endoscopy of accessory nasal cavity revealed that it was small as compared to normal nasal cavity and did not communicate with the ipsilateral nasal cavity. The diameter of the normal anterior nasal opening was less on left side as compared to right side. Unilateral supernumerary nostril may occur because of the Assuring of the lateral nasal process during fetal growth.
Fosa nasal supernumeraria es una anomalía congénita muy poco frecuente, que incluye una nueva fosa nasal con o sin cartílago accesorio. En el presente caso de fosa nasal supernumeraria izquierda estaban presentes, una pequeña cavidad de unos 3 mm de diámetro y cartílago lateral accesorio inferior. La cavidad estaba revestida con membranas mucosas y llena con descarga mucoide. La endoscopía nasal de la cavidad nasal accesoria reveló que ésta era pequeña en comparación con la cavidad nasal normal y que no se comunicaba con la cavidad nasal ipsilateral. El diámetro normal de la apertura nasal anterior fue menor en el lado izquierdo en comparación con el lado derecho. La fosa nasal unilateral supernumeraria puede ocurrir a causa de las fisuras del proceso lateral nasal durante el crecimiento fetal.

Se trata de un tumor de baja frecuencia constituido de células plasmáticas que pueden aparecer a nivel de cabeza y cuello. Estos constituyen menos del 1 por ciento de las neoplasias malignas de esta región. Deben ser diferenciados del mieloma múltiple, lo que puede ser dificultoso porque un variable porcentaje va asociado a un desarrollo más tardío de esta patología. Describimos dos casos de plasmocitoma solitario parietal. La clínica, diagnóstico y los problemas terapéuticos(radioterapia, cirugía o combinación de ambos) son discutidos y revisados en la literatura
Solitary plasmocytoma is a rare plasmactic cell tumor occurring in the head and neck. These constitute, less than 1% of all head and neck malignancies. They must be differentiated from multiple myeloma because a varying percentage may be associated at a later date with the development of multiple myeloma. We describe two cases of plasmocytomas, both in parietal bone. The clinical, diagnosis and therapeutic problems (radiation, surgery or a combination of both) are discussed and reviewed in the literature
