Purpose: To describe innovative surgical technique for closure of large defect following complicated preauricular cyst excision secondary to prior failed excision attempts, infections, and drainage procedures. Preauricular cysts must be widely excised including any fistulous tracts in order to reduce recurrence rates; however, the resultant large local excision poses cosmetic challenges.

Methods: Retrospective chart review of 3 patient cases who underwent excision of recurrent preauricular lesions involving cervical parotid flap closure. Read More

Neonates often have congenital lumps or sinuses. It is expected that pediatricians will distinguish those with important physiologic implications from those without. Accurate understanding of these lesions is important for the practitioner to avoid unnecessary tests and anxiety and to ensure that seemingly benign lesions with important implications are addressed in a timely manner.

Congenital entities sharing imaging characteristics with true pathologies occasionally are discovered incidentally in adults. These may occur in the neck, chest, abdomen/pelvis, or musculoskeletal systems. Although these incidental findings share imaging features with true pathologic processes, up-to-date knowledge and assessment with the most appropriate imaging modalities generally allow a distinction between congenital entities that may be safely dismissed and pathologic processes requiring further assessment and treatment.

Branchial cleft cysts are the most common lesions in the lateral neck with ectopic thyroid tissue found only rarely within these cysts. Over the years, multiple cases of papillary thyroid carcinoma arising from these ectopic thyroid tissues have been described in the literature with these cases sharing a normal thyroid gland on surgical and histological evaluation. Recently, however, there are three cases of papillary thyroid carcinoma in a branchial cleft cyst reported to be the result of metastasis from a thyroid primary. Read More

The aim of this study is to evaluate the value of multi-slice spiral CT （CT） and multi-planar reconstruction （MPR） in the diagnosis of children with parotid cleft deformity. The CT images of 55 cases of branchial cleft deformity confirmed by surgery and pathology were retrospectively analyzed. CT examination showed that 37 cases had strip-like, tubular fistula or cystic mass located in the anterior cervical triangle, anterior margin of sternocleidomastoid muscle, and 2 of them had bilateral fistula structure.

Branchial cleft anomalies are common differential diagnosis of neck masses. However, depending on the origin (1st, 2nd, 3rd or 4th arch), this pathology presents at different locations as cyst, sinus and fistula. Incomplete excision or incision and drainage of infected branchial cleft anomalies (cystic presentation) can lead to multiple recurrences. Read More

Thyroid abscesses are rare as the gland has a rich blood supply, well-developed capsule and is high in iodine. However, clinicians must be aware of this fact and make an early diagnosis as it can lead to serious morbidity if left untreated. Infection may involve one or both lobes of the thyroid gland, although the left lobe is more often affected and is successfully treated with surgery and antibiotics. Read More

Introduction: A mass in the lateral aspect of the neck may cause a diagnostic dilemma for the clinician. Cystic lateral neck masses in young adults are most often benign as the most frequent cause is a branchial cleft cyst. However, this may be a pitfall as such a cystic mass can be a first presentation of occult malignancy. Read More
