[National guidelines of diagnosis and treatment of the non-Hodgkin lymphoma].

Non-Hodgkin lymphoma comprises a heterogeneous group of haematological malignancies, classified according to their clinic, anatomic-pathological features and, lately, to their molecular biomarkers. Despite the therapeutic advances, nearly half of the patients will die because of this disease. The new diagnostic tools have been the cornerstone to design recent therapy targets, which must be included in the current treatment guidelines of this sort of neoplasms by means of clinical trials and evidence-based medicine.

[Cystic neoplasm of the pancreas: a ten years experience].

Background: Pancreatic cystic lesions (PCL) are identified in 1 % of patients who undergo abdominal computed tomography scans, because it is difficult to discriminate clinically between benign and malignant PCL. The PCL must be distinguished from inflammatory pseudocysts, which can have a similar radiographic appearance. The aim of this study was to review the incidence of PCL during 10 years.

[Perianal leukemic infiltration. Case report].

Background: Leukemic infiltration of perianal skin (leukemia cutis) is quite uncommon, and may consist of no diffuse infiltration, erythema, ulceration, fistula, and abscess. Diagnosis may be established by biopsy and adequate hematologic studies. Treatment must be conservative in patients with poorly controlled disease (sitz baths, antibiotics, radiotherapy), and surgical in patients with risk of fulminant sepsis and death.

[Chronic invasive rhinocerebral mucormycosis].

Rhinocerebral mucormycosis is a fulminant fungal disease that typically presents acutely in patients with diabetic ketoacidosis or immunosuppression. The case of a 55 year-old male patient is presented; the patient experienced chronic infection that involved nose, paranasal sinuses, hard palate, orbit, pterygopalatine fossa, infratemporal fossa with cavernous sinus thrombosis and compression of the internal carotid artery which develops in insidious manner after metabolic imbalance with predominantly ocular symptoms. The patient was managed with Amphotericin B and radical surgical debridement of affected tissue, the patient presenting cure without complications or added disabilities.
