Abstract
Chondroid syringoma is a rare, benign, appendegeal neoplasm. It was initially termed as mixed tumor as it comprises both epithelial cells and chondromyxoid stroma. It usually presents as a slow growing, solitary, painless, subcutaneous, or intracutaneous mass, frequently in the head and neck region. Cytological features usually include the presence of both components, similar to histology but aspiration of only one component or atypical features can pose challenges in diagnosis. According to literature, only a few single case reports describing the cytological features of chondroid syringoma has been published. We report three cases of chondroid syringoma and its differential diagnosis on cytology.

Pleomorphic Adenoma of External Auditory Canal: Case Report of First Endoscopic Resection and Literature Review. ACTA ACUST UNITED AC 2020; 56:medicina56050248. [PMID: 32443830 PMCID: PMC7279297 DOI: 10.3390/medicina56050248] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2020] [Revised: 05/14/2020] [Accepted: 05/15/2020] [Indexed: 11/26/2022]
Abstract
Ceruminous pleomorphic adenoma is a very rare, mostly benign tumor originating from the ceruminal glands in the external auditory canal. Histologically, it is a mixed tumor with epithelial and stromal parts of different proportions, and is recognized today by the World Health Organization (WHO) as a ceruminous adenoma. Similar to the pleomorphic adenoma of salivary glands, recurrence or malignant degeneration with cellular atypia and metastasis can occur on rare occasions. Here, we describe an 87-year old female patient with a growing spherical mass in the right external auditory canal. After exclusive endoscopic tumor resection, a ceruminous pleomorphic adenoma was histologically diagnosed. Due to the absence of nuclear pleomorphism, no increased mitotic rate, no perineural invasion and no fusion transcripts of the MYB or MYBL1 gene loci, an adenoid cystic carcinoma could be excluded. The postoperative course was without any evidence of complications. A literature review identified 44 articles with 49 patients that were considered. Hearing loss and ear sensations were the most commonly reported symptoms. Most cases underwent an excision via an endaural or retroauricular approach. Recurrences were described in four patients, three of which had a malignant transformation.

Abstract
Chondroid syringoma (CS) is a rare benign adnexal tumor of the skin with a resemblance to pleomorphic adenoma of salivary gland, most commonly involving the head and neck region. In the present literature, reports of the cytologic appearance of CS are scarce as it is rarely encountered by fine needle aspiration (FNA). A 67-year-old woman presented with a 1 year history of a 1 cm subcutaneous nodule in the right axilla. FNA biopsy was performed revealing an epithelial-mesenchymal biphasic neoplasm suggesting CS. Surgical excision confirmed the diagnosis and demonstrated extensive ossification, an extremely rare feature, with only seven reported cases, all located on the head. CS is a rare benign adnexal tumor of the skin, often overlooked due to its unremarkable clinical presentation. FNA is a reliable tool for the diagnosis of CS and helps guide optimal surgical management.

Abstract
Chondroid syringoma, or pleomorphic adenoma of the skin, is a rare, benign skin adnexal tumor. It is usually exhibited as a slowly growing intradermal or subcutaneous nodule, typically located in the head and neck region. Because of the unremarkable clinical symptomatology of this rare tumor, the diagnosis is exclusively made retrospectively based on histological confirmation of the surgically excised tumor. We present a rare case of a chondroid syringoma located in the left medial canthus of a 58-year-old man. The patient had no symptoms and decided to excise it for cosmetic reasons only. Local excision with a macroscopic wide cuff of normal tissue was done, without destroying the aesthetic and functional structures, since the defect was restored by a finger flap. One year postoperatively, the patient has remained disease-free. Chondroid syringoma usually appears in the face but the location in the medial canthus is not mentioned in the literature for the last twenty years.

Abstract
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 well-defined 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.

Abstract
Chondroid syringoma is a rare benign skin adnexal tumor of eccrine/apocrine origin affecting commonly the head and neck region. It is also called as mixed tumor of skin because of the presence of both the epithelial and mesenchymal components. There are very few case reports of chondroid syringoma diagnosed on fine needle aspiration cytology (FNAC). We hereby report a case of giant chondroid syringoma occurring over the lower back in a 50-year-old male, diagnosed initially on cytology and confirmed by histopathology. This case is reported for its unusual size and site of occurrence. We describe the clinical features, cytology, histopathology, immunohistochemistry, and differential diagnosis of giant chondroid syringoma along with review of literature.

Abstract
Chondroid syringoma is a generally benign, adnexal tumor most commonly found in the head and neck. It is typically diagnosed retrospectively from histopathology, and careful evaluation must differentiate it from tumors of salivary gland origin. It presents as a slowly growing, subcutaneous or intradermal nodule. Treatment consists of wide local excision with a margin of normal tissue. We report a case involving a 51-year-old man with a chondroid syringoma arising from the scalp. Clinical features, histopathology, and treatment are discussed.

Rapidly growing chondroid syringoma of the external auditory canal: report of a rare case. Case Rep Med 2011; 2011:589680. [PMID: 21941560 PMCID: PMC3173968 DOI: 10.1155/2011/589680] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2011] [Accepted: 07/15/2011] [Indexed: 11/17/2022] Open
Abstract
Introduction. Chondroid syrinoma of the external auditory canal is an extremely rare benign neoplasm representing the cutaneous counterpart of pleomorphic adenoma of salivary glands. Less than 35 cases have been reported in the international literature. Case Presentation. We report a case of a 34-year-old male in whom a rapidly growing, well-circumscribed tumor arising from the external auditory canal was presented. Otoscopy revealed a smooth, nontender lesion covered by normal skin that almost obstructs the external auditory meatus. MRI was performed to define the extension of the lesion. It confirmed the presence of a 1.5 × 0.8 cm T2 high-signal intensity lesion in the superior and posterior wall of EAC without signs of bone erosion. The patient underwent complete resection of the tumor. The diagnosis was confirmed by histopathologic examination. Conclusion. Although chondroid syringoma is extremely rare, it should always be considered in the differential diagnosis of an aural polyp. Chondroid syringomas are usually asymptomatic, slow-growing, single benign tumors in subcutaneous or intradermal location. In our case, the new information is that this benign tumor could present also as a rapidly growing lesion, arising the suspicion for malignancy.

Abstract
Chondroid syringoma is a rare benign skin adnexal tumor of eccrine/apocrine origin affecting commonly the head and neck region. It used to be previously called as mixed tumor of skin because of the presence of both the epithelial and mesenchymal components. There are only few case reports describing the fine needle aspiration cytologic features of chondroid syringoma for diagnosis. We studied a 20-year-old male case from Taplejung district of Nepal came to Otorhinolaryngology out patient department with the complaints of painless, progressively enlarging swelling on the dorsum of nose. On examination, 2.0 x 2.0 cm, firm, non-tender swelling was seen on the right side of dorsum of nose. Overlying skin was normal, and the swelling was fixed to the skin but freely mobile over underlying structure. A clinical diagnosis of dermoid cyst was entertained, and the case was subjected to FNAC. FNA yielded mucoid material which on microscopy showed clusters of round cells with moderate to abundant cytoplasm embedded in chondromyxoid ground substance. The nuclei were monomorphic, centrally to eccentrically located and had fine chromatin. On the basis of these cytologic features, a diagnosis of chondroid syringoma was made. We concluded that Chondroid syringoma may be considered as a rare differential diagnosis in the swelling of head and neck region and the diagnosis can be easily confirmed or ruled out by means of fine needle aspiration cytology.
