[Scedosporium apiospermum brain abscess. Report of one case with literature review]. / Absceso cerebral por Scedosporium apiospermum. Presentación de un caso con revisión de la literatura.

Scedosporium apiospermum is a fungus found in the soil and in contaminated water and commonly cause cutaneous infections and is a rare cause of central nervous system infection. Invasive infection is usually associated with immunosuppresion. The authors present a 73-year-old woman with chronic renal disease who presented with headache for 2 weeks. Computerized tomography scans revealed a ring-enhancing lesion in left temporal lobe. An urgent craniotomy was performed and the lesion was totally removed. The patient died 5 days later. Scedosporium apiospermum was isolated in the culture of the extirpated lesion. The authors review the previously reported cases of brain abscess for Scedosporium apiospermum.

Breast tumor resembling the tall cell variant of papillary thyroid carcinoma: a case report.

The breast tumor resembling the tall cell variant of papillary thyroid carcinoma is a very unusual mammary carcinoma whose histologic and predominant nuclear features mimic a papillary thyroid carcinoma. We report the case of a 64-year-old woman who presented with a palpable nodule in the right breast. Fine needle aspiration disclosed abundant cellularity with isolated cells, sheets, and papillary formations of epithelial cells with nuclear grooves. Histologically, the neoplastic cells were arranged in a solid to papillary architecture, with follicular-like and cribriform areas. The cells were columnar to cuboidal with eosinophilic cytoplasm, clear chromatin, nuclear grooves, and occasional nuclear pseudoinclusions. Tumor cells were positive for cytokeratins, alpha and beta-estrogen receptors, progesterone receptor, androgen receptor, CEA, and bcl-2. We searched for BRAF mutations with negative results. Recognizing the cytologic and histologic characteristics of these peculiar mammary tumors that mimic thyroid carcinomas can avoid unnecessary clinical investigations.

Intradural extramedullar tuberculoma of spinal cord. Case report.

A case of intradural tuberculoma in an infant and the patient was diagnosed operated on successfully. The author's advice is to perform surgery followed by antituberculosis treatment during the recovery period.

[Primary epidermoid carcinoma of the stomach]. / Carcinoma epidermoide primario del estómago.

Squamous cell carcinoma primary of the stomach is an exceedingly rare neoplasm of unknown etiology. We report on a case of an antral tumour arising in the antrum of a 49-year-old woman. Histopathological study revealed a typical squamous cell carcinoma without evidence of glandular differentiation. Immuno-histochemical positivity for p53 suggests common etiopathogenic pathways with other histological types of gastric carcinoma.

[Dorsal medullary compression due to a primary vertebral chondrosarcoma]. / Compresión medular dorsal por condrosarcoma vertebral primario.

INTRODUCTION: Chondrosarcomas are the second commonest type of bony tumors, although they are not commonly found to be vertebral. They may originate in healthy bone or develop in a cartilaginous lesion with sarcomatous degeneration. CLINICAL CASE: A 62 year old woman complained of pain in the back and weakness of her legs. Following magnetic resonance studies a tumour at the level of the D6-D7 vertebrae was diagnosed. This was operated on and an extradural tumour, a grade 11 chondrosarcoma was removed. A local recurrence was removed two years later and three years afterwards she is still asymptomatic. CONCLUSIONS: A spinal chondrosarcoma is a tumour which usually presents with local pain and signs of spinal involvement. On magnetic resonance it is iso-intense on T1 and shows up with contrast. The treatment of choice is radical surgery since it does not respond well to oncological treatment.

[Malignant fibrous histiocytoma of the duramater]. / Histiocitoma fibroso maligno de duramadre.

Malignant fibrous histiocytoma is the most common soft tissue sarcoma in adults with the majority of cases that occur in patients between 50-70 years and most of cases occurs in male. Seventy percent originate from extremities. Primary MFH involving the central nervous system is a rare occurrence with most cases originating from the dura or leptomeninges. A case of primary intracranial malignant fibrous histiocytoma in a 60-year-old man is presented. The tumor was successfully excised and the patient remained well at follow-up of 12 months. The clinical features of this case and the therapeutic prognosis of 24 cases reported previously in the literature were reviewed.

[Smooth muscle tumor of the lower lip. A report of a case of rapid growing and increased mitotic activity]. / Tumor de músculo liso de labio inferior. Reseña de un caso de rápido crecimiento y elevada actividad mitósica.

Smooth-muscle tumors are not often found in the oral cavity. The tumors found usually are benign tumors of the angioleiomyoma type. We report a new case of oral smooth-muscle tumor, in the lower lip of a 74-year-old woman. Immunohistochemistry and electron microscopic study confirmed the nature of the lesion. Although some mitoses were visible, the outcome has been favorable.

Absceso cerebral por Scedosporium apiospermum. Presentación de un caso con revisión de la literatura / Scedosporium apiospermum brain abscess. Report of one case with literature review

Scedosporium apiospermum es un hongo que seencuentra en el suelo y en las aguas contaminadas, quehabitualmente ocasiona infecciones cutáneas y excepcionalmentepuede contaminar el sistema nervioso central.Sus infecciones se relacionan habitualmente consituaciones de inmunosupresión. Los autores presentanel caso de una mujer de 73 años con insuficiencia renalcrónica que se presentó con dolor de cabeza durante2 semanas y que en la tomografía computarizada seobservó una lesión en anillo en el lóbulo temporalizquierdo. Con el diagnostico de absceso cerebral sepracticó una craneotomía temporal y extirpación completade la lesión. La paciente falleció 5 días después dela intervención.

Histiocitoma fibroso maligno de duramadre / Malignant fibrous histiocytoma of the duramater

El histiocitoma fibroso maligno es el sarcoma de partes blandas más frecuente en el adulto, con una mayor incidencia entre los 40 y 60 años, afectando mayoritariamente a los varones. El 70 por ciento de los casos se sitúan en las extremidades. La localización intracraneal del HFM es muy poco frecuente y la mayoría de las veces se originan en la duramadre o las leptomeninges. Presentamos el caso clínico de un paciente de 60 años afecto de un histiocitoma fibroso maligno, originado en la duramadre craneal, que fue extirpado completamente, y con un seguimiento de 12 meses tras el diagnóstico. Realizamos una revisión de los 24 casos recogidos en la literatura y analizamos las características clínicas y terapéuticas. (AU)
