“…AXG in the EAC is extremely rare and clinically may mimic other benign mesenchymal tumours and tumour‐like lesions (neurofibroma, leiomyoma, haemangioma, carcinoid, fibroepithelial polyps, exostosis, osteoma, inflammatory polyps and adenomas) 7,20 . They appear as yellow to brown polypoidal, smooth, nodules which are firm to feel and around 0.5 to 1.5 cm in size.…”

“…Extracutaneous involvement is uncommon in JXG and usually manifests in the eye 6 while it is almost unknown in AXG. AXG arising in the external auditory canal (EAC) is extremely rare with very few cases reported in literature 7 . We report a case of AXG arising from EAC, the only one to be described with both cytology and histopathology correlation.…”

Juvenile xanthogranulomas (JXG) are the most common type of self‐limiting non‐Langerhans cell histiocytosis (LCH) usually presenting in infancy and early childhood. Clinically, they present as solitary to multiple rounded cutaneous nodules which resolve over time. Adult type xanthogranulomas (AXG), though histologically similar to JXG, are usually single and do not regress spontaneously. AXG arising in the external auditory canal (EAC) is a rare occurrence with very few cases reported in literature. We present a case of AXG in a 48‐year‐old man, arising from the right EAC. This case is unique as it is the only case to be described with both cytology and histology correlation. On cytology, smears showed scattered foamy histiocytes, inflammatory cells and thick stromal fragments. Cytology differential diagnoses of xanthomatous lesion, benign fibrous histiocytoma (BFH) and ceruminous adenoma were given; final diagnosis was deferred to histopathology which confirmed it to be an AXG. Thus, it is important to keep the diagnosis of AXG in mind while dealing with solitary polypoidal lesions in EAC showing prominent foam cell component. Lipidised BFH forms a close differential diagnosis, however can be excluded by subtle points on cytology and on histopathology.

Background: Pinna contributes enormously to the facial aesthetics, and also an important part of the peripheral auditory system. Although lesions of pinna are not uncommon, a comprehensive study on various lesions encountered in clinical practice have been less carried out. Early intervention and confirmation of diagnosis by histopathological examination helps not only in successful management but also in preventing disfigurement of the ear and psychosocial complications. Methodology: A Prospective study was done in the Department of ENT, for duration of 18 months, total of 30 patients of both genders in age group of 18 - 60 years with clinical features of benign lesions of pinna were enrolled in the study, and were subjected to clinical examination and history regarding onset and predisposing factors. Surgery was carried out under local anesthesia in all of the cases. Results: Majority of patients were in the age group of 31 - 40 years. Most of the patients presented with Keloid 16 (53% ) , 8 (27 % ) cases were Seroma, 3 (10 % ) were Epidermoid cysts , followed by 2 (7% ) cases of sebaceous cyst and a case of Neurofibroma. Ear piercing is the predisposing factor in most of the cases, followed by Trauma . Conclusion: Early intervention and confirmation of diagnosis by histopathological examination helps not only in successful management but also in preventing disfigurement of the ear and psychosocial complications.
