Objective: A rare case of adenoid cystic carcinoma of ceruminal gland with pulmonary metastasis presented with characteristic cytological and histological findings. Method: The biopsy specimen of the patient, a 45 year-old man with painfull, growing mass in his external auditory canal was interpreted as an adenoid cystic carcinoma. He was treated surgically and received post-operative radiotherapy. After 8 years, a distant metastasis relapse was observed. Computed tomography (CT) of the chest depicted multiple spiculated masses suggestive of metastases throughout both lung fields, the diameter of the largest measuring 2 cm. CT guided percutaneous transthoracic fine needle aspiration biopsy was performed from the largest lesion. Results: Cytological examination of the aspirates revealed large spherical hyaline globules representing basement membrane material surrounded by neoplastic cells. The cells were cohesive, closely packed, and had uniform round to oval hyperchromatic nuclei with scanty cytoplasm. These features were suggestive of an adenoid cystic carcinoma. Conclusion: Patients with adenoid cystic carcinoma could be frequently encountered with disease recurrence confined to the lung. Fine-needle aspiration cytology provided a conclusive diagnosis of adenoid cystic carcinoma. Objective: Often some of a fine needle aspiration (FNA) sample is left behind in the hub of the needle when the specimen is ejected on the slides ( Figure 1A) . Method: We have designed a device that collects this material. It consists of a plastic adaptor that has a core of polyvinyl alcohol foam protruding from its lumen at one end ( Figure 1B) . The other end of the adaptor then fits on to the syringe (Figure 1 C) . As the FNA is being performed the sample material flows up the lumen of the needle's shaft and emerges into the hub of the needle where it is absorbed into the tip of the foam core ( Figure 1D ). Smears are made by ejected the specimen from the needle onto a slide by air pressure from an attached syringe. The air passes through the foam forcing some of the sample in the foam back down the needle but some remains behind. The device is then removed and placed in a formalin specimen pot. Once fixed the core is pulled from the adaptor ( Figure  1E ), processed and sectioned as for routine histology specimens ( Objective: The presence of DCs has been studied histologically in PTC, but their presence and potential diagnostic value in thyroid FNAs has not been evaluated. Method: We assessed the presence of DCs in cytological samples of histologically confirmed PTCs (n=31) and benign thyroid nodules (BTN) (n = 29) using CD1a. Corresponding PTCs (n=11) and BTN (n=10) from surgical excisions were stained with both CD1a and Langerin. Results: CD1a + DCs were identified in 30/31 PTCs on cytology (97 %). They were either isolated in the background or more typically closely associated with tumor cell clusters. The 3 PTC cases with the least DCs corresponded to the follicular variant on histology. In contrast, most BTN (69 %) lacked CD1a + DCs. When DCs were present, they were primarily isolated in the background although 5/29 cases (17 %) contained rare DCs among tumor cells. Tumor-infiltrating DCs and background DCs were both higher in PTCs than in BTN, but only the former was statistically significant (P<0.0001 and P=0.1173 respectively). Similar findings were found on histology where all PTCs contained CD1a + and Langerin + DCs while only 2/10 BTN (20 %) contained rare DCs. Conclusion: DCs are present in FNAs of PTC, typically among tumor cell clusters, while they were absent or rare in FNAs of BTN. Thus DCs may be useful as an additional diagnostic marker for PTC.
