Subcutaneous dermoid cysts on the eyebrow and neck

Pediatric Orbital and Skull Base Pathology

Pediatric orbital and skull base pathologies encompass a spectrum of inflammatory, sporadic, syndromic, and neoplastic processes that require a broad and complex clinical approach for both medical and surgical treatment. Given their complexity and often multicompartment involvement, a multidisciplinary approach for diagnosis, patient and family counseling, and ultimately treatment provides the best patient satisfaction and clinical outcomes. Advances in minimally invasive surgical approaches, including endoscopic endonasal and transorbital approaches allows for more targeted surgical approaches through smaller corridors beyond more classic transcranial or transracial approaches.

Skin sonography in children: a review

Skin lesions are not uncommon in children, and most of them are benign. However, they can be a matter of concern. Although in most cases the diagnosis can be suspected based on clinical history and physical examination, in some cases clinical findings are nonspecific. High-frequency color Doppler US is a noninvasive technique that can play a relevant role in these cases and give important anatomical information for final clinical management. US can be helpful to avoid unnecessary surgery, plan a surgical excision and avoid advanced imaging studies such as MRI and CT, which have a lower resolution for the skin. Different lesions can look similar on US, and clinical correlation is always important. The purpose of this article is to show a variety of skin lesions that occur in children, emphasizing clinical-sonographic correlation, and to familiarize pediatric radiologists with the US technique and sonographic appearance of common skin lesions in children.

Dermoid Cyst of Nasal Tip and Nasal Septum

ABSTRACT

Dermoid cyst is a congenital and benign disease with most occur on the head and neck. It is rarely that occur on the nasal tip and nasal septum at same time and rarely repair of using nasal septum mucosa. The authors treated a child with dermoid cyst in the nasal tip and septum. Only the dermoid cyst at the tip of the nose caused the change of appearance. Dermoid cyst of nasal septum did not cause any clinical symptoms. She underwent excision of the dermoid cyst at the tip of the nose and endoscopic surgery for the dermoid cyst in the nasal septum and used the nasal septum mucosa for repair at the same time. After 6 months of recovery, the appearance of the nasal tip recovered well without obvious scar, the nasal septum area recovered well, and the local stoma was unobstructed without recurrence. The authors found that this kind of nasal septal cyst with no clinical symptoms can achieve good therapeutic effect through endoscopic surgery and repair of using nasal septum mucosa, with less damage, rapid recovery, and good prognosis.

The congenital sternoclavicular sinus: a single-institution retrospective study of 88 patients

BACKGROUND

Sinus near the sternoclavicular joint was considered as a rare congenital neck abnormality. Though it was reported as a dermoid sinus in some literatures, the embryological origin of the sinus was unclear. This study aimed at reviewing the clinical and histological characteristics and analyzing the possible embryological origin of this malformation in children.

METHODS

The medical records of all patients with congenital sternoclavicular sinus who underwent surgical resection between March 2018 through June 2020 were reviewed retrospectively. The clinical presentations, complications, histological examination, and treatment were analyzed.

RESULTS

Of the 88 patients with congenital sternoclavicular sinus included, the mean age of surgery was 2.73 ± 1.71 years old. The sinuses occurred on the left side in 73 (83.0%) cases. Sixty-three patients experienced sinus infection and 44 patients underwent incision and drainage before excision. All patients received surgical resection with one patient who recurred after surgery. Histopathological examination showed that the sinuses were lined by squamous epithelium in most patients. However, ciliated epithelium was observed in one patient and salivary glands were detected in two patients.

CONCLUSIONS

The congenital sternoclavicular sinus should be excised promptly to prevent recurrent infection. According to the ciliated epithelium and salivary gland were found in the wall of sinus, it should be viewed as the skin side remnant of the fourth branchial cleft rather than a dermoid cyst/sinus.
