Chondroid syringoma is a rare benign, skin appendageal tumor, also known as mixed tumors of the skin. The clinical presentation of chondroid syringoma is non-specific, and the diagnosis is made histopathologically. A case of a 74-year-old man presented with an asymptomatic 1.3-cmsized, firm, skin-colored, subcutaneous nodule of 8 years' duration on the superior helical rim of the left ear. Stretching of the skin over the tumor showed the "tent sign" with many facets and angles, a pathognomonic sign for pilomatricoma. The nodule was totally excised under the impression of pilomatricoma. The histopathologic findings showed the characteristic features of chondroid syringoma. Chondroid syringoma arising in the helix is extremely rare; only four cases have been reported in the literature. This case represented the fifth documented case of chondroid syringoma occurring in the helix with clinical presentation mimicking pilomatricoma and the first case involving a male patient. A review of the relevant literature is also presented.

“…However, at present, circumstantial evidence strongly suggests the majority of such tumours are of ceruminous gland origin [3]. According to the WHO classification [14], benign ceruminal gland tumours include adenoma, chondroid syringoma (pleomorphic adenoma), and syringocystadenoma papilliferum, and malignant ceruminal gland tumours include adenocarcinoma, adenoid cystic carcinoma, and mucoepidermoid carcinoma.…”

Background. Pleomorphic adenoma (PA) is a benign tumour that mainly arises from salivary glands, and PA of the external auditory canal (EAC) is very rare. The objective of this study was to clarify the clinical presentation and treatment of PA of the EAC. Method. The authors present a case of PA arising from the EAC together with a literature review. Results. A 40-year-old man complained of hearing loss and foreign-body sensation of the right ear. Clinical and radiological examinations revealed a welldefined tumour limited to the EAC, with no connection to the parotid gland. Preoperative fine-needle aspiration cytology findings were characteristic of PA. The tumour was removed en bloc with the overlying skin. Conclusion. PA of the EAC is very rare, and methods to rule out malignancy before treatment are lacking. Thus, long-term follow-up is necessary, because malignant tumours are common in the EAC and PA has malignant potential.

Ceruminous Adenoma (CA) is a benign neoplasm of ceruminous glands. Developing exclusively in the external auditory canal (EAC) with benign clinical behavior and was first reported by Hang in 1894. It is rare in humans and poses a diagnostic problem for the clinician, due to the variety of clinical presentations. This tumor is mainly composed of the ceruminous gland cells (modified apocrine sweat glands). These glands are localized deep in the skin mostly in the cartilaginous part of the external auditory meatus. We are presenting a 45 year old female patient who was referred to our otology department with a two year history of right ear blockage with progressive hearing loss, her other medical history was unremarkable. The surgical finding under microscope showed soft tissue mass under the skin that fulfilled half of the posterior inferior portion of the external auditory canal (EAC) that was completely excised under general anesthesia utilizing a postaurical approach. The excised tumor specimen after proper staining confirmed the diagnosis of ceruminous adenoma. In conclusion the CA is benign rear tumor raised from ceruminous gland in EAC slowly growing when getting bigger can block the EAC leading to heating loss; it can be presented with variety of symptom such as mild otolgia, ear blockage sensation and hearing loss treatment of choice is complete excision along with over line skin to prevent recurrence.
