A 38-year-old woman is described who presented with a slowly growing mass on the posterior aspect of the left ear. Excision and histopathologic evaluation revealed a pleomorphic adenoma (PA) originating from heterotopic salivary gland tissue. Many authors have presented cases of PAs originating from ceruminous glands in the external auditory canal or of so-called chondroid syringoma originating from apocrine and eccrine sweat glands. This is the only case in the recent literature of a PA originating from a heterotopic rest of salivary gland tissue in the retroauricular region...

Non-melanoma skin cancer is the most common type of cutaneous neoplasm worldwide. While basal cell carcinoma is the most common tumor, squamous cell carcinoma (SCC) causes higher morbidity and has a risk of metastatic spread, depending on immune status, tumor size, and desmoplastic growth. We reported the case of a 77 year old male patient with retroauricular tumor, which started growing 3 years ago and was excised, buth relapsed three times. The initial diagnosis was infundibular cyst. Delayed Mohs surgery was performed, as was an additional open lymph node biopsy of the patient's right groin, on the occasion of an indolent swelling of the same which developed within 3 months...

The objectives of the study were to introduce and investigate the reliability of a new flap for postauricular defects using the retroauricular artery perforator.Twenty auricles from 10 Asian human cadavers were dissected to examine the retroauricular perforator distribution and diameter. Fourteen patients with postauricular defects underwent reconstruction using the retroauricular artery perforator from 2013 to 2015. After locating the position of the perforator by ultrasound Doppler blood flow detection, a suitable flap was designed according to the defect's size, condition, and distance from the pedicle...

CONCLUSIONS: Adverse skin reactions were equally distributed among age groups, surgical technique, or presence of a retroauricular incision. Implant loss was observed more frequently in children when compared to adults and elderly. OBJECTIVE: A bone conduction (osseointegrated) implant can be used for rehabilitation of patients with conductive hearing loss or single-sided deafness. The surgical technique has been modified to minimize adverse skin reactions and other complications...

A 59-year-old female patient, previously healthy, immunocompetent, presented left bulbar conjunctiva lesions and nodular-ulcerated lesions on the arms and cervical region, besides left cervical and retroauricular lymphadenopathy. She had previous contact with domestic cats that excoriated her face. The diagnosis was conclusive of disseminated sporotrichosis through clinical and epidemiological history and cultures of skin and ocular secretions. It evolved with good response to oral antifungal therapy.

Lateral and sigmoid sinus malformations are uncommon and dangerous anatomical variations that surgeons may encounter when performing a retroauricular approach. We report three cases of rare temporal bone venous sinus anomalies seen in patients who underwent cochlear implant surgery. The first patient had a diagnosis of CHARGE syndrome and presented a bilateral persistent petrosquamosal sinus with sigmoid sinus agenesis, which made mastoidectomy for cochlear implantation difficult. The second patient presented an anomalous venous lake in the occipital region, which communicated the left dural venous sinuses with a conglomerate of pericranial vessels in the left nuchal region, also consistent with left sinus pericranii...

Spindle cell lipoma represents a distinct clinicopathological entity and is related to cellular angiofibroma and mammary-type myofibroblastoma. Spindle cell lipomas are composed of mature lipogenic cells and a variable number of CD34-positive spindle cells that show loss of retinoblastoma protein expression. Spindle cell lipomas occasionally express S-100 protein. We studied one case of purely dermal spindle cell lipoma and four cases of classical subcutaneous spindle cell lipoma arising in one female and four male patients (age ranged from 55 to 69 years)...

OBJECTIVE: This study aimed to evaluate and compare learning curves for the retroauricular (RA) and transaxillary (TA) approaches in endoscopic hemithyroidectomy. METHODS: The medical records of 290 patients who underwent hemithyroidectomy by either the RA or TA approach from November 2007 through December 2015 were retrospectively reviewed (113 patients with RA and 177 with TA). The two groups were compared with regard to patient characteristics, perioperative clinical results, and complications...

Epidermnoid cysts are henign, cutaneous cysts which commonly occur on face, neck and trunk. Retroauricular epidermoid cyst is rare reported which should be differentiated from auricle pseudocyst, lipoma, steatocystoma and fibroma. The hitopathological examination is a gold standard of diagnosis. Surgery of complete excision is the first choice of treatment methods.

We present a case of a 27 year-old Malian male referred to our hospital for two large, painless retroauricolar masses that had appeared two years earlier. Bilateral cervical painless lymphadenopathy was present at physical examination, without any other systemic symptoms. His history was relevant for bilateral Kimura’s disease lesions resected 5 years earlier in the same locations. Lymphocytosis and a mild hypereosinophilia were found in routine blood tests, together with increased total IgE levels. After surgery, histology showed lymphoid infiltrates with reactive prominent germinal centres containing eosinophils, suggesting relapse of Kimura’s disease, in the context of nonencapsulated fibrous proliferation with discontinuous collagen fibers, consistent with keloid...

The incidence of thyroid cancer has abruptly increased recently, with a female predominance. Conventional thyroidectomy using transcervical incision inevitably leaves an unfavorable neck scar; therefore, various extracervical approaches have been introduced to improve cosmetic satisfaction after thyroidectomy. Several reports demonstrated that these extracervical approaches have advantages not only in terms of cosmesis but also in terms of surgical outcomes and postoperative functional preservation. The retroauricular approach has advantages as the dissection area is smaller than that in the transaxillary approach (TA) and surgical anatomy is familiar to the head and neck surgeons...

BACKGROUND: Cystic hygroma is a rare benign abnormality of the lymphatic system generally occurring in young children less than 2 years old. The standard transcervical surgical treatment of cystic hygroma may often leave a permanent scar in the neck region. CASE PRESENTATION: We report a case of cystic hygroma in a 19-month-old Asian baby girl successfully treated with robot-assisted excision through a hairline neck-lift approach. We present the use of the Yang's retractor as an instrumental advancement to this surgical approach...
