Diffuse pulmonary hemorrhage syndromes occasionally present diagnostic problems if the clinical picture is not very typical. The presence of hemosiderin-laden alveolar macrophages in bronchoalveolar lavage (BAL) fluid is a useful diagnostic criterion for this entity. However, in many diffuse interstitial pulmonary diseases (DIPD) there is a lesion at the(More)
We present the case of a 16 year-old male who presented intestinal hemorrhages since childhood; he was operated in emergency for microhemangiomas located in sigmoid colon and rectum. This lesion can be considered as a complex vascular hamartoma. We review the literature and discuss the differences between this lesion and angiodysplasia.
OBJECTIVE To present our experience in the application of sentinel node (SN) biopsy in patients with breast cancer T > 3 cm without clinical evidence of axillary metastasis. MATERIAL AND METHOD Retrospective study of 393 cases in the period 2001--2006, divided into group (A) 47 patients with 3-5 cm T2N0 tumours and group (B) 346 patients T < 3 cm, N0. We(More)
UNLABELLED The sentinel lymph node (SLN) biopsy is currently the procedure of choice for axillary node staging in initial stages of breast cancer. The purpose of this study is to establish our false negative rate within a 5-year follow-up period in 258 patients with breast cancer staged with this procedure. METHODS A retrospective study on 258 consecutive(More)
We report on a case of pseudovaginal perineoscrotal hypospadias. The gross and microscopic features of this condition are described. The existence of ambiguous external genitalia without gynecomastia together with a complete inhibition of the müllerian structures is confirmed.
OBJECTIVES We report an additional case of schistosomiasis of the urinary bladder, an unusual parasitic infection in our setting, with special reference to the histomorphological findings that permitted its diagnosis. METHODS Biopsy was performed via cystoscopy and bladder tissue was obtained from an area in the trigone with an abnormal appearance. (More)
We report a case of enteritis cystica profunda observed in a patient who, owing to both his personal and familial history, had been diagnosed and suffering from Peutz-Jeghers syndrome. The patient was operated because of a clinical picture of intestinal invagination. Together with hamartomatous polyps, anatomopathological study of the segment of the small(More)
