Fine Needle Aspiration versus Fine Needle Biopsy of Biliopancreatic Lesions: Are They Really Opposing Techniques or Can They Be Complementary? Our Experience in a Large Cohort of Cases from a Single Institution.

Introduction: Nowadays, endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA), and fine needle biopsy (FNB) are considered the best procedures for the diagnosis of biliopancreatic lesions. These methods represent a milestone since they proved to be both safe for the patient and useful to achieve diagnostic material useful to plan the best treatment strategy.

Objective: Since in the literature, a debate between cytology and histology supporters is still ongoing and the trend is changing in favor of FNB, we would like to present our experience about the diagnostic yield of FNA and FNB.

Potential Difficulties in Cytological Approach of Basal Cell Adenoma of Salivary Glands: The Experience of a Single Institution.

Objective: Basal cell adenoma (BCA) is an uncommon benign epithelial neoplasm of salivary glands, which was first described by Kleinsasser and Klein in 1967 and which derives its name from the monomorphic basaloid appearance of tumor cells. This tumor represents 1-2% of all salivary gland epithelial tumors; the most common site of occurrence is the parotid gland. It usually arises in adults over 50 years of age with slight female prevalence.

Glial choristoma of the ventral part of the tongue: first report in an elderly patient.

Introduction: The aims of this report are to illustrate the first case of glial and adipose tissue choristoma at the ventral part of the tongue in an elderly patient, to discuss the possible differential diagnoses and to speculate about its pathogenesis.

Case Report: A 65-year-old female was admitted to our hospital with a swelling at the base of the tongue. MRI revealed an oval lesion with indistinct borders without contrast enhancement.

A solitary polypoid gastric metastasis 20 years after renal cell carcinoma: an event to be considered, and a brief review of the literature.

Background: The incidence of gastric metastasis is 2.6%. Although all primary neoplasms can metastasize to the stomach, most originate from melanoma or breast and lung cancer.

Role of biopsy in low-grade laryngeal chondrosarcoma: report of two cases.

Laryngeal chondrosarcomas are rare tumours that account for less than 1% of all sarcomas and originate principally from the crycoid cartilage. We report two cases: the former arising from thyroid cartilage in an 85-year-old male presenting with a palpable neck mass and hoarseness, dyspnoea and dysphagia; the other in a 54-year-old male with a mass growing from crycoid cartilage, who underwent biopsy followed by total laryngectomy. We discuss the peculiarity of the site of origin and the role of biopsy, the clinical presentation of the former case and the diagnostic and therapeutic procedures of the latter.
